"From dust to dust we live but from lunar crust we ascend" is a line so hard it hits like freight train and couldn't be more true
💯
I read your comment first, and it still hit hard
This channel is criminally undersubscribed.
@@nicholasryanscroggs8761 I agree
"From dust to dust we live but from lunar crust we ascend"
Damn that gave me chills down my spine
For importing water, we don't need water per se, just the hydrogen, cause there is plenty of oxygen being produced as a byproduct of the metal refining process. That reduces the amount of mass you need to import by 88.8 percent. Or if liquid hydrogen is too tricky to import, methane would give you both hydrogen and carbon.
Just take methane. You get carbon as well as hydrogen .
True
@@RalphButtigieg I mention that at the end of my comment.
That's a very clever solution. Of course we can't be sure yet but some of the recent proves have found what they think is deep water reservoirs. If those dont pan out though this would be a much more efficient way to get the resources the moon is lacking.@@massimocole9689
@@RalphButtigieg why not take ethanol? Less boil off and in any case you can still drink it
This is my new favorite channel. The research and extreme detail you go into and they way you lay out complex information in a way that is totally digestible to a layman like me is freaking awesome.
I came here to say this exact thing. 10/10 would recommend. primo. hot fire.
Wow that's really awesome to hear!
@@Anthrofuturism Dude I could write pages about how awesome your videos are. I've never been excited by the word regolith before. I had a dream about being a tourist on the moon the other night and racing go-karts in an indoor low gravity course with ramps!
Never had a moon dream before so I think you've really captured my imagination!
The deep technical research and economic considerations in your videos honestly make everything else seem superficial and poorly thought out, video games, TV shows, other youtube videos all fall short of what you're doing here. I really hope your channel explodes dude! ❤️
@@canilernproto3018that's incredible to hear I really appreciate it. Hearing things like this is why I keep making these videos
The thing that i love about your channel is that you’re not doom and gloom. Many others would have criticisms about certain aspects of space colonization and ultimately just doom and gloom their way through the whole thing. You on the other hand give reasons why A, B, and C wouldn’t work, but offer reasons why D, E, and F would be a better solution. I especially love the point you made about our “ultimate goal” and what it is that we are trying to do on the moon and in the realm of space itself. We can’t approach this as a “Studying Science” venture or space colonization and the greater space economy itself will never be more than a heavily government subsidized endeavor, ultimately leading us to nowhere.
On a more personal note. I feel like you should be starting your own space company or something. TH-cam is a great place to share ideas and receive feedback, but I think that the information and talent that you have won’t be fully realized until you do. I hope that this doesn’t come across as preachy, but I do feel like you have something special with these videos about moon colonization.
All in all, you’re an extremely underrated channel and I will be eagerly awaiting your next video upload.👍
I appreciate that! The future is inspiring and optimism is rational!
1. Dont ship water to the Moon please. Just the hydrogen. And make your water there, it will keep things and people warm during lunar night while doing it. Moon is mostly oxygen by mass anyway and we can get it out of rock
2. There is no atmosphere on the Moon so big and massive but very simple flywheels will work better than here. Worth considering since its just spinning piece of metal
Pure water is just an example, if that is viable then anything else is even better. And with 5 liters belter ration, you do not need to take it specially, it may take 3 days to reach the moon, taking Apollo numbers, so then those 5 liters will be delivered automatically in the form of sweat and piss(sorry for the reality of it)
Bigger quantities sure more reasonable to deliver dropping oxygen and combining with other useful stuff.
Mining itself can(probably) actually deliver plenty of it(due solar wind hydrogen in upper layers of regolith), when industry is roaring, so exporting it is just a worse case scenario.
As for wheels to store energy, yeah we forgot about it (it already took plenty of time to dig stuff) and true it is a viable option, which benefits from vacuum and lower gravity.
Flywheels have a low energy density, time and metals used to produce this cuts into profits
@@claytonwatson7307it is relatively easy to produce them locally, not that great quality to be good for any scenario, but when you compare it to stuff delivered from the earth it may make sense
Solar themeral is an option for power and heat at night. Take all that sunlight and heat a mass and then use that stored heat to drive a generator at night and the waste heat to keep things warm.
"It can be trucked anywhere... including the moon." Space Trucker, reporting for duty.
Amazing video. I got a couple points to make:
-If you look at what does the energy consumption in ISS, thermal management and oxygen production through water electrolysis is a big part. This can be streamlined with the material wealth of the moon by storing heat in hot regolith/thermal storage and oxygen, all produced during the day. Make the product early as energy storage.
-If there is limited energy during the night, don't run anything non-essential. Stop and rest. I suspect we will see a hyper-active working day for 14 days in daytime and a R&R relaxing repairing socializing night time. Byphasic work schedule. Maybe we can manage 80-90% energy demand reduction during the night with both things, I estimate. So we would need about 200kg of 500Wh/kg FPB fancy batteries per person, much more reasonable, at 10000$/Cap cost of transport of batteries. And procurement is cheap as hell.
True
I was thinking the same. In another video he made a similar mistake assuming that people would buy just as much on the moon as they buy at Walmart when they are at home, which I highly doubt. You probably wont go there for shopping lots of things as a tourist on the moon as shipping stuff there just to bring it back seems pretty pointless, so I think the import cadence for commodities would be a lot lower than he estimated per tourist

This is a good plan Ian. You need to get the book spread out as far as you can since your plan is superior to whatever NASA is doing. If you know anyone who works for NASA; that would also be great.
Bro your channel is so in depth, I love the amount of detail you go into for these videos. Keep makin vids man
Ok I’m at 1:42 but I have to stop and say “from dust to dust we live but from lunar crust we ascend”
You're not a worthless idealist, and certainly not a rat. Thanks so much for your efforts.
The polar colony scenarios assume we won't find underground fossil water/ice deposits (non-renewable veins of extractable water) similar to those found on Mars recently, or which exists on Earth in places like Libya. People looked for underground water on Mars because they're looking for life, but haven't put the same effort in look on Luna for underground water. There's also going to be metal hydrides somewhere, which could be used as a hydrogen source to make water, and oxides are everywhere on Luna. Or instead of shipping water from Earth, ship the much lighter hydrogen then use oxygen electrolytically cracked from regolith to make water. All these require lots of power, so nuclear > solar, and nuclear removes the polar constraint of solar.
Why not just make water during the 14 day light period, using much cheaper solar energy and store the products? IMO the nuclear reactor is just needed for life support, but not for industry use. During night time there are plenty of tasks that can be postponed during lunar day, like treating the products made during day time.
I think nuclear would be great for industrial use,but have solar as well. Would need to find a task to use any excess, like construction materials, charging batteries for heavy machinery and drilling etc
I was waiting for an upload dude
Solid Channel
F.y.i I binged all your videos in a single sitting
Keep it up
That's awesome! Thanks!
A flywheel battery might be more cost effective especially considering the most expensive part is pitting them in a sealed container so they can be under vacuum to negate air resistance . Something the moon comes with for free. Then we can make the energy storage moon side without all those expensive shipping fees.
@@diyp7769 A big and heavy flywheel would be a nuisance to launch, but it would also be very easy to make on the moon. Granted you would need something in the mean time that a fission reactor would be a great fit for.
@brodyrex6987 No need to launch anything since we are building all the materials we need for a flywheel battery on the Moon.
True. Due all kinds of constraints we didn't go through all the options. As an example if we have electrolysis and those nice nasa Stirling engines, well we can store energy in those electrolytic products (Some sort of mix of Si, Fe etc) and then burn the stuff in oxygen at time of need. Not so nice as flywheels but an option to. Thermal energy storing is an option to. But yeah wheels are a solid option, if we have magneto dynamic bearings for it, which is easier than on earth for it in 1/6g.
Flywheels tend to be good for bursts of power.
Thermal storage would be easier to build. Heat a mass with solar and then use that stored heat to drive a generator. Really a mirror(s), insolated container(s), a sterling engine and some pumps to move the coolant between the generator and thermal storage unit(s).
Or use solar to crack oxygen from metals and then burn metal at night to drive generators. Not the most efficient but it works.
Let's gooooooo, I haven't watched the video yet but I bet it's great, excellent work!
I agree. Shackleton will be a nightmare to develop beyond even a 5 person base, I'm pretty sure. Fsking land in the middle of a Mare with a starship and a couple of fuel cells to get your Moonlegs again after 50 years and go from there, that will be hard enough already. Landing from polar orbit in mountainous terrain to tinker around with prototypes in complete darkness, what. are. they. thinking???
... Probably afraid the Chinese might get there first....
BTW love the videos. I work in industry that does large scale things like water hydrolysis and hydrogen compression. I would hate to depend on a fuel cell to keep me alive during the lunar night. I have seen these systems breaking way to often in my experience.
Yeah, too many points of potential failure in this contraption, and hard to fix if things go south.
this just know this video is about to pop off
That'd be awesome
Always excited to tune in 🇺🇬
I have an idea. How about we just. Build the solars higher? Like, build something similar to a radio tower and put an array on top of that.
It is still quite a limited area on that crater thing. In general video does not say the pole base is impossible, a minimum it's reasoning should be robust, just water for humans is not strong enough. And if so then we have options instead of obvious choice, and then we choose something based on what we want to have in the future.
You seen the relief at poles in the video, just to make a regular railroad a few hundred km's - it will be a challenging task, and it may be the simplest of things we want to make, to make a small dent in us in space situation.
Build a tower with a mirror to focus light down onto a solar array.
Great Video Mr. Anthro! One of the best so far.
What about flywheel energy systems? With enough power generation we could build the flywheels on-site with minimal exports for copper and other materials to spin them up. Plenty of regolith that could be used to build them, then spin them up with excess energy during the day cycle and spin them down during the night cycles. Would be a lot cheaper to build, I think.
Viable option, but requires some industrial capacities, while the options were for an early situation. With industrial capacities there are more ways to address this issue and flywheels is one of them.
Flywheels tend to be better for storing bursts of power, not long term out put devices.
Forget copper. Aluminium wire will do the job well enough. You'll need more than if you were using copper, but if you're making it on-site, who cares? You don't need to ship it.
@@matthewconnor5483 was looking at specs of the one for satellites, NASA's stuff or something - it was good enough for a moon night. Overall efficiency was decent enough(not a high number, but better than nothing)
If we pollute the moon enough it will form an atmosphere.
With the (relative) ease of a lunar mass driver, it certainly does seem insane to electrolyse water ice into hydrogen and oxygen for rocket fuel. 100km track length for a 3g human capable track, 10km for a 30g material launching track. 10km is very achieveable with starship and can constantly send payloads 24/7 during lunar day time. There is no way that mining, transporting and electrolysing water into hydrolox, storing it cryogenically and then combusting it is more efficient than just launching payloads direct via solar electricity. You are also losing valuable water too. Upfront cost a 10km launcher for materials and use a starship orbiter+lander combo for human transfer while you work on building out a 100km track for humans. Eager Space has a good video on starship only lunar architecture and it looks very compelling cost wise.
And also worth mentioning that the permanently shadowed regions of the Moon make up like 0.01% (or less) of the lunar surface. I would imagine its scarcity alone would make it a prime real estate location in the far future, but it's probably not where we stake our lunar colonization efforts.
Not much prima in it, as some comments mentioned we forgot some ways to address accomulating energy, like flywheels and there is more, the problem alone probably worth a separate episode.
If you have any basic industrial capacity then there are multiple ways to address this problem.
If you wanna refuel your rockets then the pole is meaningful. But oxygen is 4/5 of mass of rocket fuel, and maybe just export oxygen where you wanted the fuel to be, it covers 80 percent of the problem.
Export it to earth orbit, for starship refueling and then they need 2 launches to refuel starship instead of 8-10-12 so that alone can help you to deliver 4-6 times more fuel in orbit(where your rockets are)
Amazing video. I'm a PhD student so I've read a lot and written (some) scientific papers. This is a scientific paper in video format. I love it.
They should play Stellaris music in the NASA offices. Maybe we’d have a moon base sooner
I want them to remember you as the person who inspired this generation to set up an economy on the moon instead of rushing off to mars.
O'Neil cylinders are cool and all, but consider this: 2 apartment buildings tethered by a cable, spinning to create gravity. Would be way easier to buil, the cable can be made long enough that the RPM would be comfortable.

Lol that'd be crazy from 8k to a million idk if I could handle that whiplash but it'd be welcomed!
At 18:00 the Picea fuel cell system comes to mind. It is readily available and stores hydrogen during the summer from excess PV-Power making it usable during the winter for heating and electricity during winter. Price is around 80.000€ for a single home system if I remember right. Also storing oxygen as well might cost quite a lot, since it needs 16 times the volume compared to the hydrogen though
hey that system is cool hadn't seen that before. Not optimized for space or regenerative but still a good estimate for power density and capability etc. thanks
@@Anthrofuturism contact them with our topic, i am sure they will answer. If not, i will give them a call tomorrow and explain what we want in german
I agree with most of your conclusions. Actually, I agree with most of the stuff you say, so please do not consider things like my breakdown of cost per can of Coke to be criticism. They’re more like reality checks, Intended to be constructive and possibly assist in refining your vision. Because I really like your vision.
Another disadvantage of settling at the poles is that it is difficult to get to the poles. There is a significant energy cost in changing from an equatorial orbit to a circumpolar orbit. And then when you wanna go home again, there is another significant energy cost in returning to an Equatorial orbit and heading back to earth.
It is much easier and much safer to land in the tropics so to speak, and it costs way less fuel. This is why we did it six times. The equatorial regions are also much better mapped and surveyed than the poles are. It would be much easier and safer to build an outpost somewhere along the equator and then go and get the water from the south pole.
Here’s some baseline numbers : the LEM ascent stage dry weight was 2445 kg, and it had 2376 kg fuel, giving it a total weight of 4821kg. So roughly half of its mass was fuel, and that pushed it all the way into orbit on the moon. It would take considerably less fuel to do a suborbital hop along a parabolic trajectory to any point on the moon. Once you’re on the ground, you can hop to any point on the moon in about 45 minutes. so takeoff from Armstrong station at the equator and land in the Shackleton ice mine, load up your -- hell, let’s call it an Eagle transporter - A couple hundred kilograms of ice, refuel, and then hop back to Armstrong station. Easy! Plotting a parabolic orbit from the lunar surface to any other point on the lunar surface is vastly fastly vastly easier than going into orbit from earth, changing to a circumpolar orbit, and the hitting a pretty small bullseye when everything is moving. Conversely, parabolic hops are cake because every point is effectively stationary relative to your launch point.
Anyway, getting back to my original point, I enjoyed this channel and I like the way you think and please don’t take anything that I say as negative. It is not intended that way.
That's another great point I didn't even consider! This extra cost of energy would also greatly impair the effectiveness of mass drivers and any other launch infrastructure
such an underrated channel
I think something that should not be over looked with small modular nuclear is the "modular" and therefore portability. Once they get local power production jump started the reactors can be moved to jumpstart new bases or installed into massive moon scaled construction/mining vehicles.
Sometimes it can help to think of not just this one step but how will it impact things down the line. The cost of nuclear just might be worth it overall.
True. There also are other ways to achieve the same result.
what about having a smaller largely automated (with up to 10 people) International icemineing/research base down there. have Shackleton and most other craters on the north and south poles resrverved but the rest can be used for commercial ice mineing.
For solar energy you just need 2 installations which guarantee at least one is always in sunlight. On the pole those two installations can be close together, so we can wire it up.
Same with the long-term plan, once you have enough industry to put a wire all around the moon at whatever latitude you chose, you can then put solar panels all along it and guarantee constant light. One power grid can easily cover the entire moon's surface, thanks to AC being long-range
The stellaris BGM is incredibly fitting for this video :)
Great video
Very well argued, you've convinced me
Welp, time to play KSP.
0:58 Because cool
You make a great case for a network of solar power satellites to beam microwave power to any location on the Moon constantly.
if lunar regolith is so non-conductive, then using a ground source heat pump to store energy from the day to the night could make more sense than using electricity for heating/cooling. maybe scaled up this could also be the easiest way to create energy storage in-situ. furthermore you could use it for power as well as heat. for working fluid you'd use gasses generated by refining or perhaps as the water storage system. to make the tubes you could use microwave drilling and would only need a large but mechanically simple pumping system
I am so glad i found this channel
As a faithful communist, and son of Gagarin, your theory of space privatization concerns me. As a fellow space industrialist, and solar civilization enthusiast, your designs intrigue me ❤
well met
damn, this is the greatest youtube channel I have ever found...
bought the book!
man I love that you are against using water as rocket fuel, it boils my blood how often people roll that one out. like have we really learned nothing from fossil fuels?? we should be trying to retain as much water on the surface of the moon as possible for future generations
When you are done with the moon could you please countinue this series and perhaps make a guide to colonize the solor system
The battery mass would be much higher than for the Megapacks, considering the relatively narrow temperature range various lithium chemistries can operate in, and very wide temperature swings on the moon. Active thermal control also requires power.
Maybe in later phases pumped storage plants could be used to store energy (although liquid w/ properties special to a moon would be needed) but I didn't do economics of it so..
Also great video❤
Unfortunately capitalism will follow us into space…
but that does mean space revolutions allowed
When it comes to manufacturing on the moon, you don’t need to manufacture the whole product, just the heavy bulky parts, and import the small but complex parts. The machines you suggested needed to be imported, the majority mass wise could be manufactured locally, with the small crucial‘special sauce’ parts imported.
Printers will do more and more complex stuff for that environment you'd hope / think.
Yes, the way to go
Import the chips/control board, cast the frames.
Outstanding video
we can use mirrors on craters to direct light on panels. mirrors are cheap
I think we should construct something akin to the Nazca lines on the Moon, visible from Earth. The lunar maria would be a good place for that. At we can put a time capsule with all of humanity's knowledge at the center.
Your Argument about consumption scaling with production may be true but it doesn't really apply here. A lot of energy will be used to produce Aluminium or Steel. All these operations don't need to happen in the three days of lunar night, so no need to store them. You can also shut down fuel production and so on, I personally think the lunar economy will need to adapt to the day night cycle, produce when the energy is cheap and only store whats essential for crew comfort for the night (At the poles at least, I still think the day and night cycle will be important everywhere on the moon, but nobody wants an economy thats on standby half the time).
Yes, true, and considering preferences about the equatorial part of the moon it is the way to address the problem, where night is more than 3 days. Here it is more that even if it is just about humans and their life support those 3 days are bad enough. And it is not like there are no solutions, and more than mentioned in the video it's just that selling poles as a solution to every problem is not such a great selling point.
I've seen a lot of your videos.
I'm a guy who enjoys reasonable meaningful goals in space and i give a lot of extra kudos to those bothering to run the numbers.
Your videos are enjoyable and well thought out. Except for one big glaring exception.
Who is "we" ? We can do a lot of stuff in space (always assuming starship works as advertised, if not, its not worth discussing) but what is its purpose ? Is that "we" means space enthusiasts ? Is that "we" the US government ? Is that "we" investors ?
There is a fundamental conflict of interest between developing space and the profit motive. And i think you recognize it.
Apart from satellites (where the focus is earth), no other plan for expansion is attractive to those interested in monetary return on investment,let alone a short term one.
I hate to get political on this, but i don't view humanity's exodus in space as possible within the capitalist frameworks
We humans. Or royal me ;)
Poland finally can into space?
The problem with hydrogen fuel cells is that thanks to molecular diffusion (basically that hydrogen molecules are the smallest molecules) hydrogen almost always leaks out over time through even the smallest imperfection in the storage vessel, so you can't store it as hydrogen for too long.
Prolonged exposure to high-pressure hydrogen also leads to hydrogen embrittlement in many materials, including steel and aluminum, leading to brittleness and cracks and increased leakage. It's also harsh on seals and valves, again leading to increasing leaks over time.
Of course, this doesn't mean that it can't be used, just that these losses have to be accounted for.
Radioisotope thermoelectric generators make for good emergency, stop gap, or backup power supplies.
But as always, nuclear reactors beats everything else.
Hydrogen is a terrible material to work with. Nuclear is pretty much the way to go in many scenarios.
If it hasn't been mentioned, check out nickle-hydrogen batteries (not NiMH). One of the first ever rechargeable batteries used in space, they're absurdly robust and tolerant to extreme temperatures. It uses mostly just a pressure vessel capable of holding hydrogen at 1200 psi, nickel, potassium (which will be found with the rare earths you'll want to be mining anyway), and water. It's effectively a nickel cadmium battery positive nickle electrode, sandwiched with some layers of fuel cell gas diffusion material and catalyst. Charging consumes water and releases hydrogen (the pressure of which is a reliable charge indicator) and the process reverses for discharge.
Interesting! Thanks
RFCs currently have very low round trip efficiency, so you'd need a lot more generation

Most of the products of space industry seem to be used to facilitate further space development.
I think there needs to be more of a discussion on how space commercialization can benefit people that arent going to space to make it more socially acceptable. And this should be more than just an allusion to trickle down economics.
"We need to build tourist resorts for the ultra rich to finance spaceship factories." is going to be a very hard sell to the average person.
Public opinion definitely matters if you want this to succeed and Im sure you noticed that some of the driving actors in space have taken a pretty big hit to their reputation in recent years.
"For science" isn't commercially viable but is politically, "for business" isn't politically viable but is commercially. The best thing I can think of off the top of my head is starting with "for science" but in a way that heavily utilizes private industry and nudging them in the direction of tourism, hoping they take the hint. I didn't think benefits for the average person will come until construction of orbital utilities is trivialized and we can build things like orbital solar and stuff
I do support that view that space has to deliver value even for those who never heard about it, have no interest in it etc. We can state some of benefits right now, but it will be categorized as unrealistic fantasy, no reasonable human will accept it as a real option. So we have to show what is possible, how it is possible, and then the uses we may get from that and which may be beneficial if not to all humans right away then first for those who are interested in the options.
No well known notions/discorse on how space can assist us here, in near future, even if we do not want to leave - is the biggest problem of space atm.
Arh thanks matey, aye that was interesting. Keep going laddie
THOUGHTS: we create a sewage bank that can be used as manoor to grow mushrooms and other low maintnance hardy and nutritious plants that could reduce the need for exported food and collect excess gasses for industrial applications
just to clarify the hydrogen storage method will use solar to turn the water from the fuel cell to hydrogen and oxygen and just act as a battery coz if not you are describing an infinite energy machine
Everything brought to the moon must be of the highest quality to ensure dependability. Costs would be at least 5-10x greater. Plus there would need to be a bunch of spare parts. Whatever the calculations, actual costs would be 3-5x
Someone get this man a rocket and budget!
Where are we going to put the landfill
Now, if you used microwave beams to transmit the power from 10m raised solar panels, then the transmission distance of 30km is a moot point, and solar looks a lot more attractive.
I have concerns about the Railgun, I think a better solution would be a rocket sled on a maglev rail, it wouldn't have as many cargo profile concerns for future expansion as a coil approach and you are already manufacturing oxidizer on site. Alternatively you could go nuclear for the sled. This would massively reduce wear on the rails and simply the orbital maneuvering that the sleds would need to do since your line of thrust is no longer perpendicular to your primary structural members.
There is a video on that
Steam power on the moon ticks a lot of boxes
Orbital reflectors would solve all of the solar problems
"Advanced Automation for Space Missions" + Tesla-bots + SpaceX, - Tesla-bots factory-included closed Lunar robo-economy - THIS IS THE WAY, that why we need to to to the Moon!
Yes, the way to go.
We could build an elevator from the lunar surface out past the earth moon.
With regards to importing water from Earth, it's worth noting that water is 89% oxygen by weight, and oxygen is incredibly abundant on the moon (bound up in rocks, so it will be a waste product of any metal-manufacturing industry). That means you only need to ship in the hydrogen, meaning you could the desired amount of water for one ninth the price.
True, can be coupled with carbon imports which is useful.
I saw a film awhile back: aren’t there some kind of unknown possible rock monsters on the moon? How common are they and might they pose a threat?
New vid! First commend and like!
🎉
I wonder if it would be economical to use superconducting magnetic energy storage on the moon. The vacuum nature of it all is pretty conducive for insulation and night time is already pretty close to htsc temps
Once you have water, look up Thermal power station. You only need mirrors to create the heat. Would those ultra light solar blankets do?
Maybe energy issue will be addressed with magnesium lights instead of electrical, or other solutions like that
Going retro, just like in Your excavation video
For instance there was an idea of a trolleybus-but-steam engine with one central boiler for many steam locomotives
Maybe it would be better to use the moon day radiation and sunlight to boil water or something and use it as either simple steam energy in pistons or use it as a generator
youtubes official moon man
Why chemical batteries? We have vacuum on the Moon - gyroscopes are a solution.
almost all gyroscopic losses are mechanical... do you really think if it were that easy it wouldn't already be done on earth?
@@afgor1088 On Earth we just don't need to keep much power, and there we have a better solution with pumping water up into a lake and then using it's potential energy.
During the 72hr darkness couldn't you have solar panels somewhere else that runs during that darkness to help reduce storage need
Great channel !
We will have a lot of Hg (mercury) on the Moon (after creating solar pole water mining). You can think about using this resource
Read the book its great.
Comment for the algorithm, looks like its needed.
As of now record for falcon 9 is 22 flights for booster, so information in 4:12 is outdated.
Nuclear power is very nice but in terms of storage you could have a very big Dewar flask filled with lunar regolith which you heat up during the day by hundreds of degrees. To get electricity from this you can use Peltier devices but an other option that I find appealing is a supercritical CO2 turbine which are much smaller than traditional steam turbines and work at lower temperatures but since it has moving parts it will require more maintenance. This can also be used on Earth by filling the Dewar flask with sand for example.
Any plastic bag covered with regolith is a Dewar on the moon, lol
How high of a tower would you need to build on the rim of Shackleton crater to achieve nonstop light exposure? since the moon has low gravity without atmosphere, I think suspending a tall structure even a kilometre above the surface might be feasible. I would love to hear other opinions about this idea though. Another option is molten regolith as thermal energy storage. The problem I see with SMRs is that they are developed for earth and it might be tricky to get rid of the heat quick enough with radiators on the moon, but I don't know enough about the details of the engineering. I know in one of your other videos you said we should cover the reactor in regolith to protect the astronauts working inside but if you use the ship itself as radiator, covering it might actually be disadvantageous. Then again I don't know enough about the thermal conductivity of the regolith etc
