@@TekuSPZ Yeah, but the scale of that energy would shockingly high. That rate of entropy when nothing's happening doesn't make a ton of sense. Then they use it once and the pocket universe goes poof. Don't get how using drones twice would require that level of energy.
Shame they didn't have more Janus in the show especially with him being confirmed to time travel, the actor really nailed his character as being the quirky Carter/McKay of his time.
I always liked Janus. Him and his experiments have always been a big part of the series and the book series based around it. In the book series the Wraith are revealed to be a failed Ancient experiment. Not really a big surprise there, but one of the books identify Janus specifically as the one responsible for that.
I very vaguely recall that they did mention in the show how the ancients were the reason for why the wraith were such a threat as you said through experimentation that created the first queens and such. Think the whole reason they peaked their interest was because of their unique genetics from those special bugs whose names I forgot that somehow/someway did something to their gene pool. I just put that as another mark on their record of being irresponsible as a whole.
@@ignisking759 Itratus bugs. Honestly, looking at the Stargate Universe overall, the Ancients were a complete menace to themselves. They created the Wraith and the Humanoid Replicators, both of which nearly wiped them out. They also went from near revered godlike status down to petty, political, incompetents pretty darn quickly in the show.
Kinda cool how Janis reprogrammed the city(or at least the shield) to run off one ZPM at a time considering that's all the Atlantis expedition were usually ever able to supply at any one time.
That helped a lot. He managed to reduce the shielding so the whole city could run off one amp for them because it bought enough time for the city to rise with aux power.
Can't imagine it would have been all that more interesting than some facility like the geo thermal one they found below Atlantis or that facility they found with the experimental power source for the guns protecting that other world.
It’s essentially a vacuum supercooled device to allow frictionless energy transfer, and I think they are also using some kind of temporal field technology To engulf the device meaning it’s a universe within a bottle. For example Liquid helium retains kinetic energy and does not freeze regardless of temperature due to zero-point energy. When cooled below its Lambda point, it exhibits properties of superfluidity I think using real science here ZPM’s do the same as this But on a universal scale, and since they make their own universe they can destroy it to extract energy from it, I think they would be within the realms of possibility for McKay or carter to make one its controlling the energy flow that’s the problem, how do you control the energy from a drawn out Big Bang ?
Marcus W, The Ancients figured it out and I am sure the procedure is somewhere in the Ancient Database or the factory where the ZPM's are manufactured. I am surprised that wasn't their primary mission, with the ability to make ZPM's they could then fully power Atlantis, travel and contact earth and super charge their own starships, even supercharge the Asgardian Starships.
they probably need a whole facility to produce a zpm, otherwise atlantis wouldve always hada ready supply, the only known place where zpms are produced indefinitely, but not been revealed in the series is the Asuran homeworld.
Due to the Ancient’s only using three ZPMs to power Atlantis, when they could be using any number higher than that, probably proves that it is extremely difficult to construct ZPMs in the first place. If it were easy then every single Ancient vessel would have ten ZPMs installed, making winning the war extremely easy. They must be either very time consuming to construct, take a tremendous amount of delicacy/specialised knowledge that can’t be replicated through a factory, or a combination of both.
@@quentinlemaitre2998 I think replicators are smarter that Ancients, in the sense that they can learn faster. They prob found a way to create them easily but kept it hidden.
In an alternate timeline, Naquadah generators continued to gradually advance to the point where, in the 2030s, a Mark XII series of generators had been developed. These were so advanced that only one was needed to power the shield of Atlantis (which normally requires at least one Zero Point Module to function) for almost 800 years (with assistance from solar panels) after having laid dormant for 48,000 years. (SGA: "The Last Man") On job Shepard, one Job.
I mean given the tiny little things they use normally all they'd need to do is build a big one say something comparable to a RL nuclear power reactor. Which is less an issue of technical knowledge and more of just needing time, materials and personel to build.
True, but it was probably only enough to power it at a basic strength for a short period (in comparison to a ZPM). Ancient shields and Asgard shields are known for being able to be stronger or weaker based on how much energy you pump into them. So there's probably a minimum power requirement and then after that the more energy you dump in the stronger the shield becomes. Asgard shields (potentially as advanced or more so than the Ancient shields) have bleed through. So that if there's an impact too strong for the shield to absorb, it absorbs what it can and then lets the remainder pass through. Ensuring the shields remain up without entirely causing them to fail.
What's funny is that Janus gets told that by the time humanity finds Atlantis that the ZPM's are depleted, always wondered why there wasn't backup's in storage in case they got depleted, they were in a war.
And because they were at war it's possible that those were the last one they had on hand. ...But this logic is also flawed because you would expect a room full of empty ZPMs given how quickly they deplete in combat situations.
@@MrCCollins1993 he did, five or six zpms and the planets they were on, the show only ever explored one world to get the zpm though, and rodney fucked it up by telling the locals they weren't ancients. So I guess the other planets were a plothole now. In the books after the series they do find several zpms, some with barely any charge others almost full but Janus's list is never mentioned again.
My headcanon for ZPMs is that the humans have it wrong, they don't somehow automagically pull energy from subspace, and that they're actually subspace bottles for black holes. A neat little RL compliant answer, assuming a fancy klein bottle like container is possible anyway.
You know what would have been cool of Janus to do? Tell Weir exactly where in the database the schematics are to build them. Obviously all the equipment to do so are somewhere in the city. They just havent found the schematics.
@@KoflerDavid Its an artificial contained region of subspace. There wouldnt be any life. I think the real problem is how they generate that subspace and how to actually safely contain it within the ZPM. Either way..we know its extremely complicated. Given that ZPMs have the ability to hold that energy for millions of years without decaying (actually it doesnt really decay at all, it can hold the energy within indefinitely if needed). It probably even takes the Lanteans a long time to create one. I feel like the Asurans were able to expedite that process because..well, they're nanites. They cant move faster & never rest.
@@roryedward2631 we also don't know how big Atlantis really was back then. It's conceivable that they had a similar city like the Asurans had for increased manufacturing capabilities. Atlantis would have continued to act as the hardened citadel of the council and the military.
@@KoflerDavid Atlantis is a single city. Yes they had multiple of them. We know this because they showed other city ships on the show. lol but they were never all together like the Asurans built. Remember the Lanteans were always exploring, and had outposts everywhere. Edit: Flashbacks always depict the Lantean homeworld to only contain one city ship. So they were likely spread out on multiple planets.
You know what I don't understand, what did they do with all the depleted ZPMs? Did they just store them? Did they throw them away? And why wasn't there an entry in the database about how to create more or what is needed to do so? You'd think that would be the first entry
Go look at the history of human computer interfaces & filing systems. It's most likely there but finding it is uh. Not gonna be easy. Not to mention people underestimate the requirements of performing advanced material science. I don't know what you wrote this message on but it would take Tesla or Da Vinci half a lifetime to even make the material the key/screen was made of with any kind of reliability. Also. Most importantly. ZPMs might be closer to capacitors rather than batteries so who knows how much energy you need to make the things.
@@randomrazr That's not what the system was set up to do. Janus basically slapped together a hack that was sloppy but worked, but the downside was needing to manually rotate the ZPMs. He didn't have time to program a fail-proof automatic version.
the old Elisabeth was wrong when she told the young elisabeth that her life was actually not ending since The young Elisabeth ended up becoming a replicator and ended her life frozen endlessly in space
this is the only time Weir was polite. The rest of the time in the "prime" timeline, she just gave orders, insulted Rodney and dismissed peoples concerns. Here through, she is timid, quiet voiced and polite.
David Roman we can understand them,translated into English when they are actually speaking something closer to Latin;) i know English came from Latin but still they are at least 8 thousand years too early to be speaking English, considering this is 10 thousand years ago
I would pose that you need a very large, globe-spanning network of accelerators and power generation fields in order to manufacture a ZPM. The fact that Atlantis, the last refuge, is sitting in the middle of an ocean means not only do they not have any more, _they lost the ability to make any more when they abandoned whatever metropolis world they had_ . Atlantis was their "Alpha Site" with an escape route to another galaxy.
Why didn't he manufacture more ZPMs so they would be ready to be used by the SGC team when they got to Atlantis ? That there wasn't a facility to manufacture ZPMs in Atlantis is totally unbelievable ..
The Ancients appeared to use the same sort of 'beaming' construction methoids that the Asgard did (think of building Merlin's device against the Ori) . So there probably wasn't an actual 'ZPM building shed' _per se_
@brummyuk that is pure conjecture .. It was just a plot line .. Logically there should be facilities to create ZPMs in the capital ship / city of Atlantis
i mean if it was that easy to make ZPMs they could just keep an unlimited supply and the shield going forever against the wraith. obviously it didn't work that way
@@xyeahtony1 you know it right that Janus created a time machine later on so he had time to create zpms and bring them back to Atlantis after they left so Weir and her team would find them and use them.. hell he could even bring them to the present
I dont think Janus had much time and I suspect that creating ZPM was not even an easy task even for Ancients. He chose the most accessible thing to do with the little time he had left.
@@owenphillips5600 I would be OK with just 1 final movie for Atlantis and 1 final movie for Destiny to wrap things up, even if the movies themselves were an hour long. I just want closure at this point.
Shouldn't working in parallel mean they can last longer, rather than in sequence? Since power flow out of them would be at a third than using each one at capacity.
The three being equally sized sources, there shouldn't be a difference between operating them in parallel or sequence for a constant load, assuming the load is less than the capacity of a single unit. This also assumes that the efficiency of the power source doesn't vary depending on load. Unless there is a limit to how long the units can continually output before they have to cycle, it should be the same.
fatman123526 That's just in an ideal condition. But if you look at it like an engine, and run it 100% for a period of time it would likely wear down faster than running 3 engines at 33% to produce the same affect.
Could you explain to a neanderthal how to built a nuclear reactor? And even if you could, he would still lack the capability to built it. And don't forget the ancient have a strict policy of no interference with lower beings.
I've never understood how some tech needed ancient genes to use...even relatively common tech. Yet others, including what i would think should be more secure tech...did not....
always bothered me that they never found production facilities, or shipyards, or a weapons depot. The City should have had all of those and the Military would have priorities looking for them especially since they were in a fight all the time. M60s are great, but all the Ancient Guards had side arms and there would have be some kind of weapons locker in the city.
Which brings us to the question of why the city only used 3 at a time or why the battle cruisers only used 1. How about just make the city use 50 of them at once. I can't imagine how the Wraith could have slowly picked off the Lanteans if they had an incredible and seemingly limitless power source. Arrogant or not they could have taken a stock pile of 100 ZPMs and hunted the Wraith through the galaxy with just one ship. 3 ZPMS powering shields and 3 ZPM's powering drones and pulse weapons could probably withstand simultaneous attacks from dozens of Wraith cruisers at once.
You just resummarized the Lanteans history with the wraith and my entire previous response was analyzing why the Lanteans could have been hugely more successful based on their technology. I won't say they still could have won, but if the battleships could use 1 zpm what stop them from using 2, 3,4 etc? With each additional one they become exponentially more powerful.
The Asuran Replicators had the infrastructure of an entire world to manufacture them. I doubt it was easy, but with sufficient industrial infrastructure and raw materials, it’s quite possible to engage in mass production.
Also in this timeline she didn't see even those depleted ones in present, so it's first time she saw 3 on the one table. As for backups, they were at war and under a siege for a long time. Those that didn't ascent left via gate to Earth, because they couldn't keep fighting.
Remember, the Ancients evacuated the city. Why leave convenient ZPMs around where the Wraith know to get them? The 3 in the room were just left to delay the Wraith as long as possible. Even then they kept the shield going for 10000 years. I'd imagine in peacetime operation you wouldn't need to replace them for several thousand years, so why keep potentially planet destroying batteries around doing nothing?
The ZPM's were essentially backup power supply for all intents and purposes. They were just highly sophisticated batteries that stored power, very advanced but still just batteries. Every system needs a buffer, a redundancy in case the main supply fails. That's what the ZPM's were for....as a buffer. The Ancients used other power sources and no doubt, Atlantis would have had either ion-neutrino generators like the Asgard or Naquadrah power generators capable of outputting enough power to sustain the city. By the time the Atlantis expedition arrived, those power generators would have run dry, leaving only ZPM's to power the city.
@@luminatrixfanfiction but you would think they could have fount a way to start they back up at some point. Also I don't remember either of those power sources being mentioned for the city.
@@russell5078084 Officially those power sources were never mentioned, and neither were Atlantis's other weapons systems other than drones, but the few episodes in the shows hinted that the city had more to offer than what we have seen. I'm pretty sure that Atlantis main power source was a power generator more advanced than the one the Asgards used and used the ZPM'S as backup power storage modules in the even of emergencies. All the evidence points to it.
What kills me about this: Weir is talking to a live Ancient, someone who apparently knows this technology well, and she never bothers to ask (and he never bothers to offer) to leave some detailed documentation on how to make new ZPMs. These little glowy trinkets are the key to so much power, and would have liberated both Atlantis and the other Ancient lost city ("The Tower"), if only Weir's crew had access to more, fresh ZPMs. Those things are the Holy Grail of the Stargate universe. And if you can find or make more, their abilities would blossom. So, why no asky? What could it hurt to ask?
I know this seems like a reasonable thing to assume but to be honest I'm so sick of seeing this topic come up. "Oh if only they told them where the ZPMs were". "Why do we never get ZPMs" So forgetting everything else. The ancients had the ZPMs.......and had to abandon the war. But yeah humans are going to get better use out of them. But let's say they would. Why ever, in all of the world's of anything sane, would you even assume humans would know how to make them? Is it plug and play? I mean say they find the room (there is a room on Atlantis that is out of phase, for making ZPMs, as stated by a writer) are you telling me they would know how to use the equipment? And not only that😂😂😂 but do you think he'd have time to write down the instructions on how to make them???? So all of that together "here's a sketch i made on what you need to do to make ZPMs" weir "yup I know what to do now". Like Rodney said, the tech on Atlantis is so far beyond them that they barely know what they are doing, yet they would be able to make ZPMs?? Rodney blew up half a solar system thinking he was clever, with 99% of the work already done. And not only that. But the moment they get ZPMs, all you would hear is "isn't that convenient, they now have all these super weapons". The reasons they were never introduced that way is very clear.
Pretty much anything Ancient made was the most advanced and powerful stuff in stargate, even the stuff that was millions of years old seemed to still be ages ahead of most modern day factions.
Fan speculation on my part. No-but that's because the Asgard power core (and the computer core) are designed to be within our reach. Why would you put humanity's first access to knowledge far beyond them on a WARSHIP? The Tolllans made the mistake of giving technology to people who weren't ready for it and they developed weapons and destroyed themselves. The Asgard directly gave weapons, shields, transporters, hyperdrives, computers, and power sources to humans from Earth and started out by putting it on a freaking WARSHIP!!! Why? Well, these things came with Hermiod as technical assistant. And one of the most cautious/conservative members of the Asgard's ruling council. Because it was a test. We seemed promising, but how would we behave when we had access to these things? Hermiod did not always like how we used the technology, but in peace and in war, we used it as responsibly as one could expect. That much was a test, and we passed it. The computer and its power source were given to us knowing that we could interface with them and that we would likely soon be able to understand and reproduce them ourselves, I figure. We can already reprogram stargates and the like… These were not meant to be beyond us. But the full database will take decades or more to fully understand. Which is good because it's going to take us decades, even at our current rate of advancement, to be ready to handle the things we learn. They're confident that we will figure it out. I wish I shared their confidence, looking at world events.
@@knghtbrd I dont think you are right. It is specifically said that all the Asgard are leaving behind is their WHOLE legacy. If we are talking interface, I dont think it holds any truth to it. Terrans were accustomed to the crystal technology and they even left Hermiod behind to actually assist humans with anything they needed in order to utilize it...and to supervise it. Not for the lack of knowledge...but for potential lack of morals.
You you janus if you could give us help on making ZPM’s? Sure thing here is a crystal with detailed instructions on how to manufacture zpm’s Grate thanks k bye lol ?
Marcus W It likely requires massive industrial infrastructure. Do you think a factory worker at GE could just tell you how to build a jet engine? Without the industrial resources it’s a moot point. The best he could do was give her gate addresses to worlds he believed there might be spare ZPMs on.
Consider our current best high output compact energy generation source; nuclear fission. And then consider the likely next two technologies that will replace it; fusion and antimatter. What they all have in common is that they're quite dangerous, it'd be quite reasonable to infer that whatever even more powerful energy source there'd be is also nearly as dangerous. In this case the production of artificial subspace time dimension energy generation mcguffin is probably not something you'd place right in the middle of your capital.
@@7thwiew yet the city is what they left in to travel to another galaxy .. They took everything they would need .. So I think it was just a plot line .. Somewhere in the city there had to be a facility to manufacture ZPMs they just never found it
I imagine a simple answer to this question would be that such facilities might have been relatively massive undertakings. Consider the size of our current nuclear power facilities. I can imagine the ancients fully expecting to have established their outposts in the pegasus galaxy with a timeline in place to build zpm factories in due time. However after the establishing their outposts they encountered something they didn't expect. The wraith, an enemy with military capabilities that rivaled their own. zpm factories would have become a relatively low priority under such circumstances.
@@xadam2dudex Look at stargate universe it shows the tech of the ancients way before atlantis but still they had a fully autonomous spaceship making stargates. The ancients probably had ZPM production ship and they just took it with them.
So what exactly was the point of her staying there again? If she already told him to install the failsafe mechanism, then they don't need the power to last longer, the city is going to rise to the surface anyways. She just wasted her entire life.
we already knew the shield would hold till they get there, the issue was that it failed and the city didn't rise. so she could've went with Janus and fuck around with him instead of waking up evry 3k years to change around the batteries which will still fail at the same time.
if the city had risen early the Wraith might have found it first, so she had to wake up every 600 years to cycle the ZPMs. What I don't understand is how she could have aged that much if she had to wake up about 17 times (10000 years / 600), it looks like she had aged 50 years or so, 50/17= ~3, so every time she woke up she would have to spend 3 years awake before going back into suspended animation to age that much. Surely it doesn't take that long to switch out a ZPM? I would assume an hour tops.
@@Rikard_Nilsson clearly the stasis isn't a perfect status ala time dilation, rather some form of metabolic hibernation in which one still ages. 10,000 years is still impressive as all hell.
@@Rikard_Nilsson Later episodes shows that the hibernation tech still cause the people inside to age really slowly. We only have few cases where the person retained their youth.
I hate the ancients and their tech in this show, it opens up so many plot holes and ridiculous situations. If 3 ZPM shields can survive a wraith onslaught for 1000's of years and the weight of an entire ocean for 10,000 years why not just install 5-6 of them on each Aurora Class battleship with lasers, 3 ZPM for shields, 2 for weapons. A few ships could tank and solo the entire Wraith army in like 10 years and given the Ancients occupied like 3 galaxies minimum and were around for at least a million years it seems ridiculous that they lost to the wraith. The alliance storyline is really dumb too, they could have wiped out the goa'uld several times over. The time of Ra was like 3000 BC so the 4 extremely advanced allied races basically did fuck all for 5000 years and then humans show up and completely wipe out the goa-uld in the space of 30 years even after Anubis upgrades them massively.
But they can't, that is the reason they sunk their city into the ocean. To weaken the energy beams of the wraith. The shields could hold back the ocean for thousand of years, but not the weapon attack of the wraith. The water absorbed most of the energy of the wraith weapons and that's why the city survived.And the ancient won every battle with the wraith, but the problem was that there were too many wraith and too few ancient. While there ships were protecting one world the wraith had ships in thousand other systems killing humans. And don't forget at this time the wraith already got hands on zpms themself, because the ancient got careless. In the beginning the wraith were no real threat for the galaxy. Just another experiment of the ancient gone wrong, like the replicators. But the ancient were so focused on achieving Ascension, that they did not care until it was to late and the wraith had integrated their zpm technology into their own cloning facilities. And that was the reason for all their mistakes, they just did not care anymore. And it is what they do til today. The Ancient won't interfer, just sitting around in their ascended form doing nothing.
This makes very little sense to me... First of all, why would it give more power in sequence than when used together? It's still the same amount of power... Secondly, it didn't give more power... The shield collapsed at almost the same time in both timelines, what really saved them was the failsafe mechanism.. So there was really no point in leaving Weir in the stasis and waking her up periodically to change the ZPMs... Or am I missing something?
If ZPMs act similar to batteries, having 3 installed at a time would actually be better, less power draw on each ZPM. Each would last significantly longer. A battery drains a lot faster at a higher current/power load. Assuming something similar is true for a ZPM.
Using them all together means they are all depleted together. Using them in sequence and rotating them means only one is powering the shield at a time and is depleted then the next one takes its place. It only extended the time a little bit but that combined with Janus' failsafe was enough to save the expedition.
Domihork, you are not accounting for atrophy. Think of it like this. Can a battery in -40 degrees Celsius condition hold a charge as long as another that is in room temperatures? This is merely an analogy but when you consider wear and tear on technology that is run continuously, there are variables to account that cause diminishing returns. Most likely, whatever the zpm's were made of, have diminishing efficiency if run together instead of sequentially.
I think it's pretty simple. A ZPM loses power, even when "idle". If you have all three active, you have the full idle energy loss on all of them. If you only have one active at a time, and the others in... I don't know, energy saving mode or whatever, then you only have 1/3 of the idle energy loss. In war-time, where the shield needs constant high energy input due to weapons fire hitting the shield, you can't risk that one ZPM is depleted and you have to start up another one. Keeping all three of them operating is the solution that gives you the most room for incoming damage or outgoing energy requirements. Also, the show established that one ZPM can only supply that much power at a time (when they tried to lift the city up at the end of S3, while the shield was being under attack). Three ZPM's could likely pull the full weight of a Wraith- or Replicator onslaught, while lifting the city up from the face of the planet and delivering it, under fire, into hyperspace. But when you are talking about a three-thousand year time period of constantly having the same energy requirements, you can unplugg two ZPM's and, after 3333 years you plug in another one. For a short time, both are working in sync, then the first one is completely depleted, and the other one is supplying the full energy requirements on it's own. You just need someone monitoring the process - pushing some buttons on a console and perhaps manually plugging the ZPM in. Another explanation might be the voltage that is left on those ZPM's after 10.000 years. Think about it like with your phone battery. Your phone shuts itself off automatically at what, 1%? But that one percent is still enough to boot it up again. However, at 0,3%, it might not be enough anymore. So, one ZPM at 1% is strong enough to supply the shields, the lights, and some other stuff - but three ZPM's at 0,3% are not strong enough to do all of that at the same time. Like a river, where water flows through. There is a minimum amount of water in relation to the dimensions of a river, to ensure the flow of water. if you split that amount of water up into three seperate rivers of the same size, the water probably stops flowing.
Yeah I thought about it. They had naquadah reactors to keep the city running later in the series. if design of ZPM would even allow recharging, they could store excess power in ZPM so they can use it as high power battery to power shields, but only for some time as their generation is limited.
Zero point energy is some wack sci-fi bullshit meant to be a free form of infinite energy or a way to get the most energy out of a given amount of space by maximizing entropy in that point of space. ZPM's were "charged" when they were created. Basically, they were supposed to be a completely isolated part of the universe where nothing at all exists and you extract energy from the "quantum foams" random fluctuations. I know there was an episode where Janus tried to "extract energy out of the universe itself instead of the isolated pocket" and it resulted in an unstable condition, ending with McKay blowing up a planet.
One would think these ZPMs, once depleted, could be replaced and if given enough time disconnected, would recharge on their own. Recyclable/rechargeable batteries. This seems more like what the ancients would of created.
There was no implication that they would recharge themself. ZPMs as shown were creating pocket universe inside them, and after they reached maximum entropy, that pocket universe would reach what we would call heat death, a completely uniform state that you cannot extract energy from. I like to imagine that Project Arcturus, if finished, would be used to recharge ZPMs. But perhaps we are looking at it wrong. Replicators had their own design of ZPMs iirc, so it's possible that creation of those was not *that* hard given knowledge and facilities, and humans can't make them because that technology wasn't that public, like nuclear weapons irl. We know the principle, but details and materials are a bit harder to get.
why in the bloody hell didn't she ask him to take 5 minute and explain how they make them or better yet, conjure a dozen or so for her before he leaves. how about giving her the key to the super secret zpm storage locker. who the hell runs a city like this? lol. well california, detroit, nvm
They were leaving the city and he helped Weir in secret so didn't have time for anything extra. While Atlantis has the data how to make them it is simply too advanced to reverse engineer. Ancients didn't bother with "Making ZPMs for dummies guide" unlike the Asgard. The guy acutually had a super secret lab but it had a different purpose.
I love how these zero point modules later became as long lasting and efficient as AAA batteries.

Honestly, looking at the Stargate Universe overall, the Ancients were a complete menace to themselves. They created the Wraith and the Humanoid Replicators, both of which nearly wiped them out. They also went from near revered godlike status down to petty, political, incompetents pretty darn quickly in the show.
Plus they made the Ori. They were truly there own worst enemies. Makes sense once you are at the top of the tree.
@@Erakius323 They didn't make the Ori dude
@@WarGrowlmon18 I thought the Ori was a breakaway faction of ancients?
Kinda cool how Janis reprogrammed the city(or at least the shield) to run off one ZPM at a time considering that's all the Atlantis expedition were usually ever able to supply at any one time.
That helped a lot. He managed to reduce the shielding so the whole city could run off one amp for them because it bought enough time for the city to rise with aux power.
wish they made a episode of how they were built and powered
Can't imagine it would have been all that more interesting than some facility like the geo thermal one they found below Atlantis or that facility they found with the experimental power source for the guns protecting that other world.
It’s essentially a vacuum supercooled device to allow frictionless energy transfer, and I think they are also using some kind of temporal field technology To engulf the device meaning it’s a universe within a bottle.
For example
Liquid helium retains kinetic energy and does not freeze regardless of temperature due to zero-point energy. When cooled below its Lambda point, it exhibits properties of superfluidity
I think using real science here ZPM’s do the same as this But on a universal scale, and since they make their own universe they can destroy it to extract energy from it,
I think they would be within the realms of possibility for McKay or carter to make one its controlling the energy flow that’s the problem, how do you control the energy from a drawn out Big Bang ?
Marcus W, The Ancients figured it out and I am sure the procedure is somewhere in the Ancient Database or the factory where the ZPM's are manufactured. I am surprised that wasn't their primary mission, with the ability to make ZPM's they could then fully power Atlantis, travel and contact earth and super charge their own starships, even supercharge the Asgardian Starships.
they probably need a whole facility to produce a zpm, otherwise atlantis wouldve always hada ready supply, the only known place where zpms are produced indefinitely, but not been revealed in the series is the Asuran homeworld.
@@thehantavirus Hard to say since the replicators could churn them out like nothing.

@@robertg7249 Are the comics cannon or fan made?
@@xRemRooodx Probably cannon. I haven't read any fanfics yet
Unfortunately, a lot of them kind of were.
Due to the Ancient’s only using three ZPMs to power Atlantis, when they could be using any number higher than that, probably proves that it is extremely difficult to construct ZPMs in the first place. If it were easy then every single Ancient vessel would have ten ZPMs installed, making winning the war extremely easy.
They must be either very time consuming to construct, take a tremendous amount of delicacy/specialised knowledge that can’t be replicated through a factory, or a combination of both.
Creating a universe does seem pretty difficult ngl
And especially when they go over replicators and forget to take a few of them🥲
@@SSS-sz8mg seems to be a habit of the Atlantis crew. Always forgetting about those ZPMs..
But that doesn’t explain why the replicators had an unlimited amount.
@@quentinlemaitre2998 I think replicators are smarter that Ancients, in the sense that they can learn faster. They prob found a way to create them easily but kept it hidden.
In an alternate timeline, Naquadah generators continued to gradually advance to the point where, in the 2030s, a Mark XII series of generators had been developed. These were so advanced that only one was needed to power the shield of Atlantis (which normally requires at least one Zero Point Module to function) for almost 800 years (with assistance from solar panels) after having laid dormant for 48,000 years. (SGA: "The Last Man")
On job Shepard, one Job.
I mean given the tiny little things they use normally all they'd need to do is build a big one say something comparable to a RL nuclear power reactor. Which is less an issue of technical knowledge and more of just needing time, materials and personel to build.
True, but it was probably only enough to power it at a basic strength for a short period (in comparison to a ZPM). Ancient shields and Asgard shields are known for being able to be stronger or weaker based on how much energy you pump into them. So there's probably a minimum power requirement and then after that the more energy you dump in the stronger the shield becomes. Asgard shields (potentially as advanced or more so than the Ancient shields) have bleed through. So that if there's an impact too strong for the shield to absorb, it absorbs what it can and then lets the remainder pass through. Ensuring the shields remain up without entirely causing them to fail.
What's funny is that Janus gets told that by the time humanity finds Atlantis that the ZPM's are depleted, always wondered why there wasn't backup's in storage in case they got depleted, they were in a war.
And because they were at war it's possible that those were the last one they had on hand.
...But this logic is also flawed because you would expect a room full of empty ZPMs given how quickly they deplete in combat situations.
It was also 10,000 years later, it was reasonable to expect them to be exhausted after that time
Did he give Weir a small list of planets where they could find more ZPMs though?
@@MrCCollins1993 he did, five or six zpms and the planets they were on, the show only ever explored one world to get the zpm though, and rodney fucked it up by telling the locals they weren't ancients. So I guess the other planets were a plothole now.
In the books after the series they do find several zpms, some with barely any charge others almost full but Janus's list is never mentioned again.

@@aleky98 Or ask how the Ancients refer to the ZPMs
I was always hoping they would find 3 ZPMs
Well...
They did
The return…
My headcanon for ZPMs is that the humans have it wrong, they don't somehow automagically pull energy from subspace, and that they're actually subspace bottles for black holes. A neat little RL compliant answer, assuming a fancy klein bottle like container is possible anyway.
I was under the impression they have a little self contained pocket of artificial subspace they draw vacuum energy from
@@Utubesuperstar they do
You know what would have been cool of Janus to do? Tell Weir exactly where in the database the schematics are to build them. Obviously all the equipment to do so are somewhere in the city. They just havent found the schematics.
I fear that the tricky part about building one is verifying whether the bottle universe inside is indeed lifeless.
@@KoflerDavid Its an artificial contained region of subspace. There wouldnt be any life. I think the real problem is how they generate that subspace and how to actually safely contain it within the ZPM. Either way..we know its extremely complicated. Given that ZPMs have the ability to hold that energy for millions of years without decaying (actually it doesnt really decay at all, it can hold the energy within indefinitely if needed). It probably even takes the Lanteans a long time to create one. I feel like the Asurans were able to expedite that process because..well, they're nanites. They cant move faster & never rest.
@@roryedward2631 we also don't know how big Atlantis really was back then. It's conceivable that they had a similar city like the Asurans had for increased manufacturing capabilities. Atlantis would have continued to act as the hardened citadel of the council and the military.
@@KoflerDavid Atlantis is a single city. Yes they had multiple of them. We know this because they showed other city ships on the show. lol but they were never all together like the Asurans built. Remember the Lanteans were always exploring, and had outposts everywhere.
Edit: Flashbacks always depict the Lantean homeworld to only contain one city ship. So they were likely spread out on multiple planets.
@@roryedward2631 fair enough :)
You know what I don't understand, what did they do with all the depleted ZPMs? Did they just store them? Did they throw them away? And why wasn't there an entry in the database about how to create more or what is needed to do so? You'd think that would be the first entry
Go look at the history of human computer interfaces & filing systems.
It's most likely there but finding it is uh.
Not gonna be easy. Not to mention people underestimate the requirements of performing advanced material science. I don't know what you wrote this message on but it would take Tesla or Da Vinci half a lifetime to even make the material the key/screen was made of with any kind of reliability.
Also.
Most importantly.
ZPMs might be closer to capacitors rather than batteries so who knows how much energy you need to make the things.
what i dont get is why did she need to wake up each time to set the next zpm down. couldnt the systemm do it automactially
Surely, they have been studied and stripped apart but it might take decades before they can replicate it even with Asgardian knowledge.
@@randomrazr That's not what the system was set up to do. Janus basically slapped together a hack that was sloppy but worked, but the downside was needing to manually rotate the ZPMs. He didn't have time to program a fail-proof automatic version.
Out-of-Universe, they can't "make more" because that would solve almost All the problems in the entire series.
Imagine the ancients showing up and just going to a closet filled with ZPMs.

Would just leave a few nuclear power cores around NYC?
@@Slacker28 ZPMs are not "nuclear power cores" 😏 Now, Project Arcturus... that's more dangerous.
@@nousername5673 I was referring to how dangerous they can be
I would pose that you need a very large, globe-spanning network of accelerators and power generation fields in order to manufacture a ZPM. The fact that Atlantis, the last refuge, is sitting in the middle of an ocean means not only do they not have any more, _they lost the ability to make any more when they abandoned whatever metropolis world they had_ .
Atlantis was their "Alpha Site" with an escape route to another galaxy.
Why didn't he manufacture more ZPMs so they would be ready to be used by the SGC team when they got to Atlantis ? That there wasn't a facility to manufacture ZPMs in Atlantis is totally unbelievable ..
The Ancients appeared to use the same sort of 'beaming' construction methoids that the Asgard did (think of building Merlin's device against the Ori) . So there probably wasn't an actual 'ZPM building shed' _per se_
@brummyuk that is pure conjecture .. It was just a plot line .. Logically there should be facilities to create ZPMs in the capital ship / city of Atlantis
i mean if it was that easy to make ZPMs they could just keep an unlimited supply and the shield going forever against the wraith. obviously it didn't work that way
@@xyeahtony1 you know it right that Janus created a time machine later on so he had time to create zpms and bring them back to Atlantis after they left so Weir and her team would find them and use them.. hell he could even bring them to the present
I dont think Janus had much time and I suspect that creating ZPM was not even an easy task even for Ancients. He chose the most accessible thing to do with the little time he had left.
Meanwhile the replicators had shitloads of ZPM's on their world....
Hopefully with the new series we will finally be able to manufacture them
I’m still holding on to hope there will be another show! I’m not hopeful, I’d settle for a new book series though
Yeah, especially since McKay was already experimenting with extracting vacuum energy, he just needed to figure out the pocket universe part.
@@owenphillips5600 I would be OK with just 1 final movie for Atlantis and 1 final movie for Destiny to wrap things up, even if the movies themselves were an hour long. I just want closure at this point.
Woulda been nice to hear what the Ancients called their own power sources 🤔
Potentia. Idk od IT IS oficial name od made up
Potentia. That was what they referred to them.
this dude is so smart? why does he pull all 3 zpms.....under an ocean lol
Shouldn't working in parallel mean they can last longer, rather than in sequence? Since power flow out of them would be at a third than using each one at capacity.
The three being equally sized sources, there shouldn't be a difference between operating them in parallel or sequence for a constant load, assuming the load is less than the capacity of a single unit. This also assumes that the efficiency of the power source doesn't vary depending on load. Unless there is a limit to how long the units can continually output before they have to cycle, it should be the same.
fatman123526 That's just in an ideal condition. But if you look at it like an engine, and run it 100% for a period of time it would likely wear down faster than running 3 engines at 33% to produce the same affect.
I agree with you.I'm just assuming ideal because everything the ancients "made" always seems to run that way.
The Ancients were perfect, but not...
They were perfect when the plot needed them to be lol.
could hve left few extra modules for the future humans to use
she could have asked how or where zpms are produced
Could you explain to a neanderthal how to built a nuclear reactor? And even if you could, he would still lack the capability to built it. And don't forget the ancient have a strict policy of no interference with lower beings.
I've never understood how some tech needed ancient genes to use...even relatively common tech. Yet others, including what i would think should be more secure tech...did not....
always bothered me that they never found production facilities, or shipyards, or a weapons depot. The City should have had all of those and the Military would have priorities looking for them especially since they were in a fight all the time. M60s are great, but all the Ancient Guards had side arms and there would have be some kind of weapons locker in the city.
i wounder how easy it must be to make zpm's if the replicators have more than they use
very easy, considered they had many to power thier cities, and a satellite beam weapon.
Which brings us to the question of why the city only used 3 at a time or why the battle cruisers only used 1. How about just make the city use 50 of them at once. I can't imagine how the Wraith could have slowly picked off the Lanteans if they had an incredible and seemingly limitless power source. Arrogant or not they could have taken a stock pile of 100 ZPMs and hunted the Wraith through the galaxy with just one ship. 3 ZPMS powering shields and 3 ZPM's powering drones and pulse weapons could probably withstand simultaneous attacks from dozens of Wraith cruisers at once.
You just resummarized the Lanteans history with the wraith and my entire previous response was analyzing why the Lanteans could have been hugely more successful based on their technology. I won't say they still could have won, but if the battleships could use 1 zpm what stop them from using 2, 3,4 etc? With each additional one they become exponentially more powerful.
A lot of zpm = boom
The Asuran Replicators had the infrastructure of an entire world to manufacture them. I doubt it was easy, but with sufficient industrial infrastructure and raw materials, it’s quite possible to engage in mass production.
My zipper would break if I saw three working ZPMs! Hell, it'd break with one! Get your act together Amazon...I'm not getting any younger!
Why can she not believe her eyes.
Sure the zpms are an amazing technology but wouldn't it stand to reason that their creations would have a backup?
she couldn't believe it cause it was rare for earth to even have 1 mostly depleted ZPM, and here she's looking 3 fully charged and function ones
Also in this timeline she didn't see even those depleted ones in present, so it's first time she saw 3 on the one table.
As for backups, they were at war and under a siege for a long time. Those that didn't ascent left via gate to Earth, because they couldn't keep fighting.
Why is it that they spent all that time looking for ZPMs, and not the instructions in the Atlantis database on how to make them?
Pity he couldn't build a few spare ZPMs.
*zpm's appear*
Vergil: that's a lot of power
I mean cool but why not 30? Or even better, why not keys instructions, and directions to a ZPM fab, on Atlantis or off it?
What I find ridiculous is that they didn't have an extensive supply of those moduals stored in the city.
Remember, the Ancients evacuated the city. Why leave convenient ZPMs around where the Wraith know to get them? The 3 in the room were just left to delay the Wraith as long as possible. Even then they kept the shield going for 10000 years. I'd imagine in peacetime operation you wouldn't need to replace them for several thousand years, so why keep potentially planet destroying batteries around doing nothing?
@@Starjumper2821 Why leave Atlantis then? The Wraith could eventually control it.
The ZPM's were essentially backup power supply for all intents and purposes. They were just highly sophisticated batteries that stored power, very advanced but still just batteries. Every system needs a buffer, a redundancy in case the main supply fails. That's what the ZPM's were for....as a buffer.
The Ancients used other power sources and no doubt, Atlantis would have had either ion-neutrino generators like the Asgard or Naquadrah power generators capable of outputting enough power to sustain the city. By the time the Atlantis expedition arrived, those power generators would have run dry, leaving only ZPM's to power the city.
@@luminatrixfanfiction but you would think they could have fount a way to start they back up at some point. Also I don't remember either of those power sources being mentioned for the city.
@@russell5078084 Officially those power sources were never mentioned, and neither were Atlantis's other weapons systems other than drones, but the few episodes in the shows hinted that the city had more to offer than what we have seen. I'm pretty sure that Atlantis main power source was a power generator more advanced than the one the Asgards used and used the ZPM'S as backup power storage modules in the even of emergencies. All the evidence points to it.

Well We Known He Likes Taking Baths, Thanks For The Wonderful Commentary :) Please Subscribe
Funny fact a zpm is Just an extremial powerfull battery xD
What kills me about this: Weir is talking to a live Ancient, someone who apparently knows this technology well, and she never bothers to ask (and he never bothers to offer) to leave some detailed documentation on how to make new ZPMs. These little glowy trinkets are the key to so much power, and would have liberated both Atlantis and the other Ancient lost city ("The Tower"), if only Weir's crew had access to more, fresh ZPMs. Those things are the Holy Grail of the Stargate universe. And if you can find or make more, their abilities would blossom. So, why no asky? What could it hurt to ask?
The rest of the story. Same as if they added in the drones. It's ruins the story
I know this seems like a reasonable thing to assume but to be honest I'm so sick of seeing this topic come up. "Oh if only they told them where the ZPMs were". "Why do we never get ZPMs"
So forgetting everything else. The ancients had the ZPMs.......and had to abandon the war. But yeah humans are going to get better use out of them. But let's say they would. Why ever, in all of the world's of anything sane, would you even assume humans would know how to make them? Is it plug and play? I mean say they find the room (there is a room on Atlantis that is out of phase, for making ZPMs, as stated by a writer) are you telling me they would know how to use the equipment? And not only that😂😂😂 but do you think he'd have time to write down the instructions on how to make them???? So all of that together "here's a sketch i made on what you need to do to make ZPMs" weir "yup I know what to do now".
Like Rodney said, the tech on Atlantis is so far beyond them that they barely know what they are doing, yet they would be able to make ZPMs??
Rodney blew up half a solar system thinking he was clever, with 99% of the work already done. And not only that. But the moment they get ZPMs, all you would hear is "isn't that convenient, they now have all these super weapons". The reasons they were never introduced that way is very clear.
he gave her a list of planets with zpms
Are ZPMs more powerful than Asgard reactor on the ships?
Pretty much anything Ancient made was the most advanced and powerful stuff in stargate, even the stuff that was millions of years old seemed to still be ages ahead of most modern day factions.
Fan speculation on my part. No-but that's because the Asgard power core (and the computer core) are designed to be within our reach. Why would you put humanity's first access to knowledge far beyond them on a WARSHIP? The Tolllans made the mistake of giving technology to people who weren't ready for it and they developed weapons and destroyed themselves. The Asgard directly gave weapons, shields, transporters, hyperdrives, computers, and power sources to humans from Earth and started out by putting it on a freaking WARSHIP!!! Why?
Well, these things came with Hermiod as technical assistant. And one of the most cautious/conservative members of the Asgard's ruling council. Because it was a test. We seemed promising, but how would we behave when we had access to these things? Hermiod did not always like how we used the technology, but in peace and in war, we used it as responsibly as one could expect. That much was a test, and we passed it.
The computer and its power source were given to us knowing that we could interface with them and that we would likely soon be able to understand and reproduce them ourselves, I figure. We can already reprogram stargates and the like… These were not meant to be beyond us. But the full database will take decades or more to fully understand. Which is good because it's going to take us decades, even at our current rate of advancement, to be ready to handle the things we learn.
They're confident that we will figure it out. I wish I shared their confidence, looking at world events.
@@knghtbrd I dont think you are right. It is specifically said that all the Asgard are leaving behind is their WHOLE legacy. If we are talking interface, I dont think it holds any truth to it.

Why wasn't there a facility to manufacture new ZPMs in Atlantis ? Since they don't last forever how would make new ones ?
Consider our current best high output compact energy generation source; nuclear fission. And then consider the likely next two technologies that will replace it; fusion and antimatter. What they all have in common is that they're quite dangerous, it'd be quite reasonable to infer that whatever even more powerful energy source there'd be is also nearly as dangerous. In this case the production of artificial subspace time dimension energy generation mcguffin is probably not something you'd place right in the middle of your capital.

I imagine a simple answer to this question would be that such facilities might have been relatively massive undertakings. Consider the size of our current nuclear power facilities.

However after the establishing their outposts they encountered something they didn't expect. The wraith, an enemy with military capabilities that rivaled their own. zpm factories would have become a relatively low priority under such circumstances.

So what exactly was the point of her staying there again? If she already told him to install the failsafe mechanism, then they don't need the power to last longer, the city is going to rise to the surface anyways. She just wasted her entire life.
Uhhh they did this all in secret kinda. What she was supposed to do anyway also she had to do something with the ZPMs every 3k years or something.
we already knew the shield would hold till they get there, the issue was that it failed and the city didn't rise.
so she could've went with Janus and fuck around with him instead of waking up evry 3k years to change around the batteries which will still fail at the same time.
if the city had risen early the Wraith might have found it first, so she had to wake up every 600 years to cycle the ZPMs.
What I don't understand is how she could have aged that much if she had to wake up about 17 times (10000 years / 600), it looks like she had aged 50 years or so, 50/17= ~3, so every time she woke up she would have to spend 3 years awake before going back into suspended animation to age that much. Surely it doesn't take that long to switch out a ZPM? I would assume an hour tops.

I hate the ancients and their tech in this show, it opens up so many plot holes and ridiculous situations. If 3 ZPM shields can survive a wraith onslaught for 1000's of years and the weight of an entire ocean for 10,000 years why not just install 5-6 of them on each Aurora Class battleship with lasers, 3 ZPM for shields, 2 for weapons. A few ships could tank and solo the entire Wraith army in like 10 years and given the Ancients occupied like 3 galaxies minimum and were around for at least a million years it seems ridiculous that they lost to the wraith.
The alliance storyline is really dumb too, they could have wiped out the goa'uld several times over. The time of Ra was like 3000 BC so the 4 extremely advanced allied races basically did fuck all for 5000 years and then humans show up and completely wipe out the goa-uld in the space of 30 years even after Anubis upgrades them massively.
But they can't, that is the reason they sunk their city into the ocean. To weaken the energy beams of the wraith. The shields could hold back the ocean for thousand of years, but not the weapon attack of the wraith. The water absorbed most of the energy of the wraith weapons and that's why the city survived.And the ancient won every battle with the wraith, but the problem was that there were too many wraith and too few ancient. While there ships were protecting one world the wraith had ships in thousand other systems killing humans. And don't forget at this time the wraith already got hands on zpms themself, because the ancient got careless. In the beginning the wraith were no real threat for the galaxy. Just another experiment of the ancient gone wrong, like the replicators. But the ancient were so focused on achieving Ascension, that they did not care until it was to late and the wraith had integrated their zpm technology into their own cloning facilities. And that was the reason for all their mistakes, they just did not care anymore. And it is what they do til today. The Ancient won't interfer, just sitting around in their ascended form doing nothing.
This makes very little sense to me... First of all, why would it give more power in sequence than when used together? It's still the same amount of power... Secondly, it didn't give more power... The shield collapsed at almost the same time in both timelines, what really saved them was the failsafe mechanism.. So there was really no point in leaving Weir in the stasis and waking her up periodically to change the ZPMs... Or am I missing something?
If ZPMs act similar to batteries, having 3 installed at a time would actually be better, less power draw on each ZPM. Each would last significantly longer. A battery drains a lot faster at a higher current/power load. Assuming something similar is true for a ZPM.
Using them all together means they are all depleted together. Using them in sequence and rotating them means only one is powering the shield at a time and is depleted then the next one takes its place. It only extended the time a little bit but that combined with Janus' failsafe was enough to save the expedition.
Domihork, you are not accounting for atrophy. Think of it like this. Can a battery in -40 degrees Celsius condition hold a charge as long as another that is in room temperatures? This is merely an analogy but when you consider wear and tear on technology that is run continuously, there are variables to account that cause diminishing returns. Most likely, whatever the zpm's were made of, have diminishing efficiency if run together instead of sequentially.
@@TianarTruegard Not necessarily. See my previous post above.
I think it's pretty simple. A ZPM loses power, even when "idle". If you have all three active, you have the full idle energy loss on all of them. If you only have one active at a time, and the others in... I don't know, energy saving mode or whatever, then you only have 1/3 of the idle energy loss.
In war-time, where the shield needs constant high energy input due to weapons fire hitting the shield, you can't risk that one ZPM is depleted and you have to start up another one. Keeping all three of them operating is the solution that gives you the most room for incoming damage or outgoing energy requirements.
Also, the show established that one ZPM can only supply that much power at a time (when they tried to lift the city up at the end of S3, while the shield was being under attack). Three ZPM's could likely pull the full weight of a Wraith- or Replicator onslaught, while lifting the city up from the face of the planet and delivering it, under fire, into hyperspace.
But when you are talking about a three-thousand year time period of constantly having the same energy requirements, you can unplugg two ZPM's and, after 3333 years you plug in another one. For a short time, both are working in sync, then the first one is completely depleted, and the other one is supplying the full energy requirements on it's own. You just need someone monitoring the process - pushing some buttons on a console and perhaps manually plugging the ZPM in.
Another explanation might be the voltage that is left on those ZPM's after 10.000 years. Think about it like with your phone battery. Your phone shuts itself off automatically at what, 1%? But that one percent is still enough to boot it up again.
However, at 0,3%, it might not be enough anymore.
So, one ZPM at 1% is strong enough to supply the shields, the lights, and some other stuff - but three ZPM's at 0,3% are not strong enough to do all of that at the same time. Like a river, where water flows through. There is a minimum amount of water in relation to the dimensions of a river, to ensure the flow of water. if you split that amount of water up into three seperate rivers of the same size, the water probably stops flowing.
Thumbed this shit down for just cutting the video short....
Janus is really evil☝
Too short a clip

I don't understand why they simply can't recharge them.
Yeah I thought about it. They had naquadah reactors to keep the city running later in the series. if design of ZPM would even allow recharging, they could store excess power in ZPM so they can use it as high power battery to power shields, but only for some time as their generation is limited.
Zero point energy is some wack sci-fi bullshit meant to be a free form of infinite energy or a way to get the most energy out of a given amount of space by maximizing entropy in that point of space. ZPM's were "charged" when they were created. Basically, they were supposed to be a completely isolated part of the universe where nothing at all exists and you extract energy from the "quantum foams" random fluctuations. I know there was an episode where Janus tried to "extract energy out of the universe itself instead of the isolated pocket" and it resulted in an unstable condition, ending with McKay blowing up a planet.
Entropy
Basic thermonuclear astrophysics
One would think these ZPMs, once depleted, could be replaced and if given enough time disconnected, would recharge on their own. Recyclable/rechargeable batteries. This seems more like what the ancients would of created.
There was no implication that they would recharge themself. ZPMs as shown were creating pocket universe inside them, and after they reached maximum entropy, that pocket universe would reach what we would call heat death, a completely uniform state that you cannot extract energy from.
I like to imagine that Project Arcturus, if finished, would be used to recharge ZPMs.
But perhaps we are looking at it wrong. Replicators had their own design of ZPMs iirc, so it's possible that creation of those was not *that* hard given knowledge and facilities, and humans can't make them because that technology wasn't that public, like nuclear weapons irl. We know the principle, but details and materials are a bit harder to get.
why in the bloody hell didn't she ask him to take 5 minute and explain how they make them or better yet, conjure a dozen or so for her before he leaves. how about giving her the key to the super secret zpm storage locker. who the hell runs a city like this? lol. well california, detroit, nvm
They were leaving the city and he helped Weir in secret so didn't have time for anything extra.
While Atlantis has the data how to make them it is simply too advanced to reverse engineer. Ancients didn't bother with "Making ZPMs for dummies guide" unlike the Asgard.
The guy acutually had a super secret lab but it had a different purpose.
How long do you think it would take to teach you how to build a fission reactor?
And do with the tools they actually have available.
