Imagine being born in 1890. You watch a trip to the moon at age 12 and become fascinated. The next year, you see the wright brothers fly the first powered aircraft, something that seemed impossible before. You spend your life watching the technology get better and better until aged 79 you see man land on the moon. A feat that, as a young kid, could only happen in science fiction. 🤯
The 20th century was the era of sci fi come true, but nobody seemed to realize it. WW1 was like a sci fi war, technologies that had never been seen or used before in combat vs outdated tactics from a quickly receeding era. Tanks, aircraft, artillery, chemical and biological weapons, landmines, trenches, and everything else. It was like nothing ever seen before.
I'm pretty sure they're referring to "A Trip To The Moon," the French film from 1902 that happens to be the first thing said in the video.@@josephdooley981
Thank you for explaining the re-upload in the video description!! An explanation may seem like a small detail but that transparency is something I appreciate.
Cyrano came up with magnets a long time ago, he said to throw them in the air while wearing metal. After the magnet pulled you up throw it again. One or two bugs to work out. His other plan was to gather dew into bottles, tie the bottles to yourself and wait for the dew to raise and it would pull you up. Again a few bugs. Otherwise great ideas.
Loved the video! And I have to admit that every time the words "rocket fuel" were mentioned (a lot!) I couldn't help but think about NewsRadio and the great Phil Hartman's character Bill McNeal doing ads for "Rocket Fuel Malt Liquor -- Daaamn!" LOL - happy memories.
the real problem with magnetic proportions canon is the fundamental fact the air resistance that to play load needs to pass at its fastest. basically burns up before it gets to the lighter air
Didn't mention the possible accidental launch of a manhole cover, (if it didn't disintegrate in the atmosphere it would have made it to space) from early nuclear bomb testing.
Larry Niven wrote about an orbiting space escalator, where cargo could be transported to the bottom end by planes, then lifted into space where the spaceships can take it. It would work for bringing stuff from space to Earth, so the spaceships never have to enter the atmosphere to land. HUGE advantage is your ships can be designed non-aerodynamic, however the ships have to be assembled off-Earth.
Spinlaunch may be a scam - there's a lot of questionable details in the available footage, such as that membrane that the projectile pierces not being under and kind of negative pressure as the projectile pierces it - if the chamber is in near-vacuum as they claim, then even with a rapid-cycling airlock system, that membrane should be concave just before the projectile pierces it, but it isn't. Also, the tattered edges of the membrane should be pulled in due to the lower pressure on the inside, but that doesn't happen either.
Gerald Bull was not the only rail gun/ballistics engineer killed in that year, nearly a dozen Canadian and American experts in those fields died under questionable circumstances in an 18 month period.
i got into a debate about using the largest mountain on Mars as a launch platform into space. The individual insists we dont have a rocket fuel that can get us off that rock that works in such a thin atmosphere, and im over here arguing the sling launch method shown about 4 minutes in. A key point i also pointed out is that we use compressed or liquid gasses to use rocket fuel in space where there is no atmosphere whatsoever, so his argument was already partially void. its perfect for getting anything off that rock that isnt human. Even those samples that are scattered all over the surface
I still like the idea of using a weight at the end of a super long cable, using the centripetal force of the spinning Earth to keep it aloft, and using that cable as an elevator.
I'm curious how the cable interacts as it repeatedly enters earth's atmosphere. It seems like it would be passing through more often than it would be lifting things, so I imagine there'd be a lot of wear on it
This could work with a cardioid skyhook, though notably this design of tether requires a counterweight 1000-2000x the mass of the payload (en.wikipedia.org/wiki/Skyhook_(structure)#Rotating_skyhook). So you need another skyhook, the ability to redirect an asteroid into orbit, or enough moon industry to provide the counterweight. Also of note is that you don't need booster rockets to maintain orbit, you can use long cables that push off the Earth's magnetic field: en.wikipedia.org/wiki/Electrodynamic_tether
In the 1936 science fiction movie "Things To Come" one of my favorite movies, written by H.G.Wells, they use a space gun to propel themselves into space.
The moon would have to contain VERY rare minerals to justify the expenditure. Then there are issues of how to regulate lunar mining so we don't wind up with space slavery.
It's already pretty much debunked. They are overselling their dead end. Or in other words: The remaining 92% mentioned in this video are not easier then the first 8.
I say we build a space gun at the bottom of the ocean, build a barrel that goes up to the surface, and use a floating platform at the surface of the ocean to stabilize the barrel's end. No need to scale a mountain, and the barrel is more or less protected from environmental wear. Maintaining the barrel would be as easy as having a platform that travels up and down the exterior of the barrel.
I remember first hearing about that specific kind of "moon shot" in, of all things, a graphic novel. Planetary, "Spacetime Archaeology" I think? The group of main characters (I don't suppose you can call them superheroes) find a HUGE cannon in the middle of the US (I think South Dakota but it's been decades). The barrel was something like a kilometer long and kinda swooped up at its terminus, looking like a whacked out oil pipeline, and according to the world-lore was built in 1885 or so, to fire a "musket ball" (hollow metal vessel) containing three travelers, into a translunar orbit. The STRANGE part? The vessel got into orbit! Just not a stable one. And it came crashing back DOWN, nearly exactly where it started off, and thus the team had to come find out what had just crashed into the Earth... Planetary was great fun, and very weird in the best ways, but that was the story that got me reading up on space elevators and so forth :D
Fixed the test pattern in place of the Weather Balloon but still have a Russian flagged, Soviet designed, fighter bomber in a graphic demonstrating a project explored by a US Government agency (NASA) and a US corporation (Boeing).
We have the ability to predict weather a week or two in advance and measure atmospheric currents. The balloon idea is not as far fetched as it may seem.
Another thing to be said about skyhooks is that there's other alternatives to using rockets to boost the satellites orbit. You can also just use solar power and long cables to directly push off of the Earth's magnetic field: en.wikipedia.org/wiki/Electrodynamic_tether So I think if included in a proposal that would made it better because you can completely avoid further rockets.
Covered lot's of decades old ideas that are also covered in Wikipedia articles, but missed all of the newest technologies (other than SpinLaunch). See Issac Arthur's "Mass Drivers Versus Rockets" for more up-to-date technologies.
I love some of these! I thought about magnetic barrel launchers too, but! they cost a hell of a lot to build & maintain even after factoring in the cost reduction of each launch, plus they are a huge security/national risk. Which sucks. But a buoyant system with towers & suspension, using copper cables & deciding to use a nitromethane & hydrogen peroxide blend for burning into the barrel together with making them generators during this that make a Bernoulli's Principle effect for air in front of the capsule (ship) made it more feasible when using a mountain to mountain setup where it just barely skims the ground with the curvature of the Earth to provide gravitation energy, wind energy & solar included while having trash & sewage being made to become profit that turns into fuel. It was still around 200 Billion to make, & cost about 2 billion every year to 5 depending on the recoating of the inside of the barrel, geo-political resources, employees, splitting the tube to more easily get in to maintain, etc etc. So I decided on non-atmosphere planets it makes more sense than on ours that are much smaller. Then balloons are nice, but they come with a primary drawback of control & no horizontal velocity increase. Which makes them annoying to deal with, even if you use a hydrogen to make them buoyant & suck it out at the end. Its still not worth the fuel to get it into orbit, no horizontal! No go for regular use, sadly. But I felt that wasn't good enough & said, "I can do that better!" So I did. A vacuum is the easiest way to get buoyancy, when using a tensegrity approach that likes using the potential vacuum energy in a peristaltic manner, that once speed gets to the appropriate amount I can acoustically vibrate to heat air coming in with diaphragms (that have little electrically conductive fiber optics) light (constructively & destructively (best way is convergence & divergence wave frequency refraction & reflection field areas for how you combine the fiber optics) done so that way it can effect the air & the electron orbits as effectively as possible to induce a light emittance & or a yanking off the orbit for ionization) , electricity (positive/negative ion plasma wind that can have pulsing frequencies of electric current running through it which makes me get a z-pinch & shear of electromagnetic field effects for movement) together with electromagnetic coils as a part of the diaphragms + stators down the path because it has to handle the forces going through with the correct materials to help. Because peristaltic pumping produces specific wave frequencies & densities (not wave frequencies the same as luminosity is different that light frequency) this means a Deval nozzle peristaltic pump is best to make this work. A sideways hourglass that is convergence at first with slight elongated divergence to introduce greater total length for increased tapering speeds to give us a Venturi effect to further increase pressure & speed for the outflow of now combusted air that has 2 different charges as a plasma. Which then can exothermically react & be further heated with the acoustic cooling for the forward intake & light tube/fiberoptic areas (but wait there's always more, turns out piezoelectrics are here & solar panels fit to the outside with the correct cloth ceramic that is invisible to the light being absorbed but helps with you guessed it heat & sound wave propagation forwards & into intakes together with the ionic solid state wind effects that are needed to increase the total band gap frequency reduction thanks to electrons already moving around nearby (which layering solar panels as very small tiles between a internal rigid structure is the only way to do this...soooo there is that) which reduce the field area (orbit hall effect is what the transistor it is that they are talking about but whatever mossfet not allow to be solar panel that work with light jiggle wiggles as a type of light emittance conversion to electron movement that generates a nucleus movement as a positive effect that that shrinks and forces a vacuum negative to then create a electron but whatever) size because its gained extra energy from electron already moving (field effects shabooom!!! baby! *finger pistols*), which further helps increase the vacuum plug in front of the rigid air ship this already would have to have been to have vacuums be its primary source of buoyancy. The faster it goes, the more compression but the more buoyancy it gains, but that also is directly proportional to the vacuum assisted diaphragms that gain a increased total force for all psi outside to faster moving less dense air inside relative to them. Which means the peristaltic pumps are more efficient at higher speeds & altitudes, but it also means I am a giant rigid airship that acoustically pumps air from below to the front of the ship at the highest altitude using the skin as that huge speaker it is. Which says, horizontal velocity is gained massively & I can get into low Earth orbit with no, That's Right!!!!, no fuel at all! size 5 averaged out across the whole word cargo ships length, height 3, width 3. but it starts off at, only like 1 to 2. Its shaped phallically too....wh-which...I mean is efficient soooo....*holds back smile* is needed for the speeds here & the increased total buoyancy at those speeds and altitudes for total surface area for acoustic pump control & gathered air together with the lifting body characteristics, with phallic cleft kenards & sides of the shaft fuselage mini-wing/stators/kenards that introduce vortex effects like stated in my reverse bellend-aerospike engine rigid vacuum airship video I did like...just looked april 27th 2024. which is almost a year ago is what it feels like. time flies. anyways you stay in a...cabin in the rear which has to be shaped...oblong like....hahaha, look. I know, look, hold on *holds up hand* its because its a huge rudder surface area with a massive space behind where the exhaust is that connects it to there, which increases the total surface area with a vacuum that extends into the exhaust which means greater total control even at extremely high altitudes. So...The balls i guess yes you stay in there along with the extra air in the other. The entire fuselage is a massive connected (like an aircraft carrier) spongey like origami folding & sliding telescope latch locking vacuum area increase vacuum breaches happen which means they can be closed off & not worried about. With interconnected lines for all the extra air pumping going through them but then at high enough altitude they close down & become Quite rigid. somewhat flexible, but still.
No, this really one of my most efficient designs I made, its not about phallic stuff. It...just works out that way sometimes, for some of you that's great others its not. So moving on... After low Earth orbit is achieved a second craft (hopefully non manned but not much if it can't be helped) like the one you are in comes in and docks to fill your cabin area up with fuel, which you latch & spring tension it down with bags & tubes connecting it....yes similar I know...biomimicry is still good, doesn't matter. This expands the cabin area and creates a tension that helps squeeze them back to size allowing for a reduction of total pumping losses. which is great!!!! Yes...yes it is very much that way right now. So, to move forward though it turns into you keep an already decent amount of fuel & oxidizer on board then added more. But wait there's even more, the fuselage can slide & move back the solar panels until they "peacock" out behind it with a bunch of coils & tubes for cooling. The coils are just hollow copper cables that have refrigerant in them that release IR & endothermically react to then phase change & endothermically split to then endothermically combine with ionic, catalytic, & light based channels with they converge to. We keep a certain amount of atmosphere with us & generate a charged atmosphere that we run electricity through & through the airship to create an electromagnetic field & electrostatic field that convectively & light-wise cools us & generates electricity using linear generation as we are a huge electrostat & magnet as well during that. Going through charged ion fields, other electromagnetic fields, allows us to gain electricity on top of the solar panels & the piezoelectrics which help recapture everything inside. Almost done. We have thermophoto voltaics inside of the engine & for the solar panels for red shifted/slowing down blue shifted light. Since the inside is so massive, bio & synthetic reactors that use pressure based, heat based, material & filter based, together with light based, enzyme based, & electrical based catalytic processes to filter air, grow crops, recycle waste (fecal, plastic, urine, etc), & even help produce resources to then grow, print, or otherwise turn into nutrients, medicine, electricity, etc. Now most of these processes are already well understood chemical reactions that aren't going to make people suddenly like them when profit needs a non-closed loop system to continue to operate a capitalist system of economy. It operates at a different timescape as well. While producing very large volumes suddenly, or a constant stream that isn't massive but always there. It does it automatically & has to be treated like a huge (like our bodies) organ that has to be fed & maintained to actually work correctly. So... Not what they like. Land in the south pole moon, use the cold & open up the bottom hatch while having a suspended net (solar panels) using the ionic & electromagnetic & you get a "tarp" out (its to seal the airship/spaceship to the crater completely with anchors & lunar soil solvents to "glue it & weld it" effectively) to seal you in & then you dig below & use your 3d printers & big reactor to churn & mix it into soil & materials/resources for you to live there. Now, you are warm, that place is cold with a bunch of ionic wind, well that electricity. Stirling & charge piezoelectric-like that does lots of work on machines & more. Guess who designed it to live on any planet, me. That's right, its all me. no one is helping me out here. Its for interstellar & intergalactic. although I have longevity biohacking on my youtube that is just as good & detailed. sucks to be people thinking I couldn't be that good, I guess. But concept, easy even with all the details. No money, no people, no go. sucks to be alive & me I guess. Did all the work & probably can't get anywhere because no PHD & I need SSI already, with a community college dropout with a GED I got only because I was forced says all you need to know I'm screwed.
@1:30 "the cost of a rocket launch grows exponentially as payload mass increases". This is nonsense. According to the Tsiolkovsky rocket equation the cost (initial mass) grows linearly with the payload. You can easily verify the truth of this by just imaging 5 rockets taking up 5 payloads. The payload increases by a factor of 5 and the cost (number of rockets) increases by a factor of 5. What the rocket equation tells us is that the cost increases exponentially with the final velocity but only linearly with the payload.
Spinlauch sounds cool, but I don't see any way it can do better than the reusable rockets that exist now. The only alternative options that sound cost effective for use on earth ever will probably be space elevators using some future material like hundred kilometer long graphene cables
The tensile strength needed for materials that would support a space elevator is insane, orders of magnitude beyond what even graphene can do. And even if we did find an exotic material with the tensile strength to hold itself and the elevator together, there's several additional physics puzzles we haven't solved. As an end solution it sounds the most elegant, but it's also one of if not the most difficult to pull off based on our current technology. I would absolutely love a space elevator and I'm rooting for some breakthrough, but in general I hope for the best and expect little.
@The_Cyber_System I am no expert but I assume that if the other end of the tether were in geostationary orbit, you could balance out tensile strength well enough that you only need to handle the weight of the cargo and send some form of fuel up to the station on the end to maintain that orbit.
@@The_Cyber_SystemIsaac Arthur (physicist and futurist) recently published an hour-long video on space elevators that goes into a lot of the details (v=V0ju74IqW0A). He used to be very sceptical of space elevators but has now changed his mind and believes them to be entirely practical, with the only major hurdle being the ability to grow longer graphene strands. Specifically, the preliminary data we have on graphene suggests that its tensile strength should be high enough for the job (somewhere in the region of 50-100 GPa).
Spinning cable - streches and comes to same problems that space elevator has. We dont have sturdy enough cable... That might be overcome by having enough lifting helium balloons in a space elevator consept. Smaller sections of self sustaining cables and less gravitational streching. Means possible space elevator with balloons. The further we go the lift is reduced, but so is Earths gravity... 80km height might be in reach and wih added counter weights in orbit we might go all the way to the orbit.
🤔 . . . Why not use centrifugal force to launch a space glider into space? It simply needs the velocity, as well as the air to help it ‘skip’ upwards into space, just like skipping rocks & such…
Wondering if we could still Cannonize into space with less fuel than a rocket, by using a V-3 Cannon design, Or a rocket in a tube cannon. with most of the propulsion of modern rockets expelling mostly down and some of it outwards, would a cannon barrel save energy focusing all the force in one direction. The rocket cone tries to get most of this but if we had a barrel. has there been a physicist who has explored this?
China claims they will use rail guns to get to space so... The Mag Lev concept is not far off, infact in my space opera I use them as a sort of magnetically charged repulsor craft in place of a space elevator
What about a vertical tube railgun, you could control the acceleration but i cbf doing the math on how fast it’d need to get to which would determine the height, i feel somewhere between 2-5km tall would be about the limit we could build (ok i did a bit of math) at 5g you’d get roughly 50m/s every second so you’d get to the top of a 2km tower/railgun in about 8 seconds so that’s about 450m/s velocity as you poke out the top….. Unless my math is off. That sounds way better than sitting on top of a controlled explosion
Obviously a meter wide and centimeter thick ribbon of graphene could support an elevator to space. But I have no idea how many trillions of dollars it would cost to construct. Revisit this concept in another couple of decades.
Honestly, solar-powered moon laser arrays are probably my favorite proposed way to move things around the solar system. It solves a ridiculous number of issues, and you could probably have the spacecraft convert a small portion of the laser to power themselves. Seems like a win all around, to me.
An elevator/tower to LEO would require a base as wide as the earth itself to support the vertical weight of it’s 250 mile height. Basic engineering folks.
No, rocket price does NOT grow exponentially in the mass of the payload . That's obviously wrong since you can put 2x the weight of stuff in space simply by launching 2x as many rockets and you save money (in the limit) by combining them into one bigger rocket. What you meant was it grows exponentially in the velocity to be achieved.
I won't be investing in spinlaunch. There are physics issues that won't go away. Like precisely releasing a payload in a vacuum that then slams into, and penetrates, a metal portal, the rocket then hits the 14.7 psi atmosphere at supersonic speeds. All that to launch relatively tiny payloads into limited numbers of orbitals.

the real problem with magnetic proportions canon is the fundamental fact the air resistance that to play load needs to pass at its fastest. basically burns up before it gets to the lighter air
That's also why the Skytram has to be so impractically long to avoid that issue by getting above the atmosphere.
I guess a vacuum chamber that long isn't practical either? You run into the hyperloop problem.
Didn't mention the possible accidental launch of a manhole cover, (if it didn't disintegrate in the atmosphere it would have made it to space) from early nuclear bomb testing.

Years ago I remember reading that Romania is trying to launch a satellite using the balloon method.

Covered lot's of decades old ideas that are also covered in Wikipedia articles, but missed all of the newest technologies (other than SpinLaunch). See Issac Arthur's "Mass Drivers Versus Rockets" for more up-to-date technologies.
I love some of these! I thought about magnetic barrel launchers too, but! they cost a hell of a lot to build & maintain even after factoring in the cost reduction of each launch, plus they are a huge security/national risk. Which sucks. But a buoyant system with towers & suspension, using copper cables & deciding to use a nitromethane & hydrogen peroxide blend for burning into the barrel together with making them generators during this that make a Bernoulli's Principle effect for air in front of the capsule (ship) made it more feasible when using a mountain to mountain setup where it just barely skims the ground with the curvature of the Earth to provide gravitation energy, wind energy & solar included while having trash & sewage being made to become profit that turns into fuel. It was still around 200 Billion to make, & cost about 2 billion every year to 5 depending on the recoating of the inside of the barrel, geo-political resources, employees, splitting the tube to more easily get in to maintain, etc etc. So I decided on non-atmosphere planets it makes more sense than on ours that are much smaller.
Then balloons are nice, but they come with a primary drawback of control & no horizontal velocity increase. Which makes them annoying to deal with, even if you use a hydrogen to make them buoyant & suck it out at the end. Its still not worth the fuel to get it into orbit, no horizontal! No go for regular use, sadly. But I felt that wasn't good enough & said, "I can do that better!" So I did. A vacuum is the easiest way to get buoyancy, when using a tensegrity approach that likes using the potential vacuum energy in a peristaltic manner, that once speed gets to the appropriate amount I can acoustically vibrate to heat air coming in with diaphragms (that have little electrically conductive fiber optics) light (constructively & destructively (best way is convergence & divergence wave frequency refraction & reflection field areas for how you combine the fiber optics) done so that way it can effect the air & the electron orbits as effectively as possible to induce a light emittance & or a yanking off the orbit for ionization) , electricity (positive/negative ion plasma wind that can have pulsing frequencies of electric current running through it which makes me get a z-pinch & shear of electromagnetic field effects for movement) together with electromagnetic coils as a part of the diaphragms + stators down the path because it has to handle the forces going through with the correct materials to help. Because peristaltic pumping produces specific wave frequencies & densities (not wave frequencies the same as luminosity is different that light frequency) this means a Deval nozzle peristaltic pump is best to make this work. A sideways hourglass that is convergence at first with slight elongated divergence to introduce greater total length for increased tapering speeds to give us a Venturi effect to further increase pressure & speed for the outflow of now combusted air that has 2 different charges as a plasma.
Which then can exothermically react & be further heated with the acoustic cooling for the forward intake & light tube/fiberoptic areas (but wait there's always more, turns out piezoelectrics are here & solar panels fit to the outside with the correct cloth ceramic that is invisible to the light being absorbed but helps with you guessed it heat & sound wave propagation forwards & into intakes together with the ionic solid state wind effects that are needed to increase the total band gap frequency reduction thanks to electrons already moving around nearby (which layering solar panels as very small tiles between a internal rigid structure is the only way to do this...soooo there is that) which reduce the field area (orbit hall effect is what the transistor it is that they are talking about but whatever mossfet not allow to be solar panel that work with light jiggle wiggles as a type of light emittance conversion to electron movement that generates a nucleus movement as a positive effect that that shrinks and forces a vacuum negative to then create a electron but whatever) size because its gained extra energy from electron already moving (field effects shabooom!!! baby! *finger pistols*), which further helps increase the vacuum plug in front of the rigid air ship this already would have to have been to have vacuums be its primary source of buoyancy. The faster it goes, the more compression but the more buoyancy it gains, but that also is directly proportional to the vacuum assisted diaphragms that gain a increased total force for all psi outside to faster moving less dense air inside relative to them. Which means the peristaltic pumps are more efficient at higher speeds & altitudes, but it also means I am a giant rigid airship that acoustically pumps air from below to the front of the ship at the highest altitude using the skin as that huge speaker it is. Which says, horizontal velocity is gained massively & I can get into low Earth orbit with no, That's Right!!!!, no fuel at all!
size 5 averaged out across the whole word cargo ships length, height 3, width 3. but it starts off at, only like 1 to 2. Its shaped phallically too....wh-which...I mean is efficient soooo....*holds back smile* is needed for the speeds here & the increased total buoyancy at those speeds and altitudes for total surface area for acoustic pump control & gathered air together with the lifting body characteristics, with phallic cleft kenards & sides of the shaft fuselage mini-wing/stators/kenards that introduce vortex effects like stated in my reverse bellend-aerospike engine rigid vacuum airship video I did like...just looked april 27th 2024. which is almost a year ago is what it feels like. time flies. anyways you stay in a...cabin in the rear which has to be shaped...oblong like....hahaha, look. I know, look, hold on *holds up hand* its because its a huge rudder surface area with a massive space behind where the exhaust is that connects it to there, which increases the total surface area with a vacuum that extends into the exhaust which means greater total control even at extremely high altitudes. So...The balls i guess yes you stay in there along with the extra air in the other. The entire fuselage is a massive connected (like an aircraft carrier) spongey like origami folding & sliding telescope latch locking vacuum area increase vacuum breaches happen which means they can be closed off & not worried about. With interconnected lines for all the extra air pumping going through them but then at high enough altitude they close down & become Quite rigid. somewhat flexible, but still.
No, this really one of my most efficient designs I made, its not about phallic stuff. It...just works out that way sometimes, for some of you that's great others its not. So moving on... After low Earth orbit is achieved a second craft (hopefully non manned but not much if it can't be helped) like the one you are in comes in and docks to fill your cabin area up with fuel, which you latch & spring tension it down with bags & tubes connecting it....yes similar I know...biomimicry is still good, doesn't matter. This expands the cabin area and creates a tension that helps squeeze them back to size allowing for a reduction of total pumping losses. which is great!!!! Yes...yes it is very much that way right now. So, to move forward though it turns into you keep an already decent amount of fuel & oxidizer on board then added more. But wait there's even more, the fuselage can slide & move back the solar panels until they "peacock" out behind it with a bunch of coils & tubes for cooling. The coils are just hollow copper cables that have refrigerant in them that release IR & endothermically react to then phase change & endothermically split to then endothermically combine with ionic, catalytic, & light based channels with they converge to. We keep a certain amount of atmosphere with us & generate a charged atmosphere that we run electricity through & through the airship to create an electromagnetic field & electrostatic field that convectively & light-wise cools us & generates electricity using linear generation as we are a huge electrostat & magnet as well during that. Going through charged ion fields, other electromagnetic fields, allows us to gain electricity on top of the solar panels & the piezoelectrics which help recapture everything inside. Almost done.
We have thermophoto voltaics inside of the engine & for the solar panels for red shifted/slowing down blue shifted light. Since the inside is so massive, bio & synthetic reactors that use pressure based, heat based, material & filter based, together with light based, enzyme based, & electrical based catalytic processes to filter air, grow crops, recycle waste (fecal, plastic, urine, etc), & even help produce resources to then grow, print, or otherwise turn into nutrients, medicine, electricity, etc. Now most of these processes are already well understood chemical reactions that aren't going to make people suddenly like them when profit needs a non-closed loop system to continue to operate a capitalist system of economy. It operates at a different timescape as well. While producing very large volumes suddenly, or a constant stream that isn't massive but always there. It does it automatically & has to be treated like a huge (like our bodies) organ that has to be fed & maintained to actually work correctly. So... Not what they like. Land in the south pole moon, use the cold & open up the bottom hatch while having a suspended net (solar panels) using the ionic & electromagnetic & you get a "tarp" out (its to seal the airship/spaceship to the crater completely with anchors & lunar soil solvents to "glue it & weld it" effectively) to seal you in & then you dig below & use your 3d printers & big reactor to churn & mix it into soil & materials/resources for you to live there. Now, you are warm, that place is cold with a bunch of ionic wind, well that electricity. Stirling & charge piezoelectric-like that does lots of work on machines & more. Guess who designed it to live on any planet, me. That's right, its all me. no one is helping me out here. Its for interstellar & intergalactic. although I have longevity biohacking on my youtube that is just as good & detailed. sucks to be people thinking I couldn't be that good, I guess. But concept, easy even with all the details. No money, no people, no go. sucks to be alive & me I guess. Did all the work & probably can't get anywhere because no PHD & I need SSI already, with a community college dropout with a GED I got only because I was forced says all you need to know I'm screwed.
Go Go Sci Show!
@1:30 "the cost of a rocket launch grows exponentially as payload mass increases". This is nonsense. According to the Tsiolkovsky rocket equation the cost (initial mass) grows linearly with the payload. You can easily verify the truth of this by just imaging 5 rockets taking up 5 payloads. The payload increases by a factor of 5 and the cost (number of rockets) increases by a factor of 5.
What the rocket equation tells us is that the cost increases exponentially with the final velocity but only linearly with the payload.
False advertisement on Brilliance. They only offer 7-day free trial when I use the link provided here.
Spinlauch sounds cool, but I don't see any way it can do better than the reusable rockets that exist now. The only alternative options that sound cost effective for use on earth ever will probably be space elevators using some future material like hundred kilometer long graphene cables
The tensile strength needed for materials that would support a space elevator is insane, orders of magnitude beyond what even graphene can do. And even if we did find an exotic material with the tensile strength to hold itself and the elevator together, there's several additional physics puzzles we haven't solved. As an end solution it sounds the most elegant, but it's also one of if not the most difficult to pull off based on our current technology.
I would absolutely love a space elevator and I'm rooting for some breakthrough, but in general I hope for the best and expect little.
@The_Cyber_System I am no expert but I assume that if the other end of the tether were in geostationary orbit, you could balance out tensile strength well enough that you only need to handle the weight of the cargo and send some form of fuel up to the station on the end to maintain that orbit.
@@The_Cyber_SystemIsaac Arthur (physicist and futurist) recently published an hour-long video on space elevators that goes into a lot of the details (v=V0ju74IqW0A).
He used to be very sceptical of space elevators but has now changed his mind and believes them to be entirely practical, with the only major hurdle being the ability to grow longer graphene strands.
Specifically, the preliminary data we have on graphene suggests that its tensile strength should be high enough for the job (somewhere in the region of 50-100 GPa).
4:15 so it's a space yeeter
They made a really fast space yeeter
What about a spring or springs?
What if we could get a magnetic trebuchet to hurl the payload vehicle into space
Spinning cable - streches and comes to same problems that space elevator has. We dont have sturdy enough cable...
That might be overcome by having enough lifting helium balloons in a space elevator consept. Smaller sections of self sustaining cables and less gravitational streching. Means possible space elevator with balloons. The further we go the lift is reduced, but so is Earths gravity... 80km height might be in reach and wih added counter weights in orbit we might go all the way to the orbit.
I thought the missing footage section was a joke
Okay hear me out, Project Orion + HARP? I think it could be done!
The space cable would fail because of inertia unless the space vehicle has an engine
🤔 . . . Why not use centrifugal force to launch a space glider into space? It simply needs the velocity, as well as the air to help it ‘skip’ upwards into space, just like skipping rocks & such…
Maglev for sure
13:18 “Vernzez” ?
Wondering if we could still Cannonize into space with less fuel than a rocket, by using a V-3 Cannon design, Or a rocket in a tube cannon. with most of the propulsion of modern rockets expelling mostly down and some of it outwards, would a cannon barrel save energy focusing all the force in one direction. The rocket cone tries to get most of this but if we had a barrel. has there been a physicist who has explored this?
Ok, BALS is funny, but Rockoons is hilarious. They shoulda stuck with that.
So we are getting the Jakob elevator from megaman x 8?
China claims they will use rail guns to get to space so... The Mag Lev concept is not far off, infact in my space opera I use them as a sort of magnetically charged repulsor craft in place of a space elevator
What about a vertical tube railgun, you could control the acceleration but i cbf doing the math on how fast it’d need to get to which would determine the height, i feel somewhere between 2-5km tall would be about the limit we could build (ok i did a bit of math) at 5g you’d get roughly 50m/s every second so you’d get to the top of a 2km tower/railgun in about 8 seconds so that’s about 450m/s velocity as you poke out the top….. Unless my math is off. That sounds way better than sitting on top of a controlled explosion
Obviously a meter wide and centimeter thick ribbon of graphene could support an elevator to space. But I have no idea how many trillions of dollars it would cost to construct. Revisit this concept in another couple of decades.
Scientists create the spinlaunch centrifuge to simulate life as your mom.
I already feel like I weigh thousands of times more than I do.
Cannon might work from low gravity of marz or moon
cannons, rockets, catapults, slings.. you missed the one where they use lasers (not joking)
Honestly, solar-powered moon laser arrays are probably my favorite proposed way to move things around the solar system. It solves a ridiculous number of issues, and you could probably have the spacecraft convert a small portion of the laser to power themselves. Seems like a win all around, to me.
Didn't Spinlaunch go bust/lose their investors months ago?
A little drunk rn and thought the title said bathrooms ☠️
0:28 well aren't rockets kinda like canons, but with the canon stuck to the projectile xD
Well aren’t projectiles kinda like elephants, but if ballistics is zoology…?
I suppose a more fitting description would be ‘a rocket is like a cannon that throws itself’, but yeah, basically.
Rocket? / cannon? Bad joke, but let the technical differentiation commence.
@TaxPayingContributor even if it's a bad one, you at least identified it as a joke. I see that as a win xD
They WILL! We just made a video about telescopes in space, and incredible things are coming in this field
You'd be hard pressed to find people willing to use a Boeing space hook these days...
Rockaloons
An elevator/tower to LEO would require a base as wide as the earth itself to support the vertical weight of it’s 250 mile height. Basic engineering folks.
Put an asteroid in orbit and make the cable extend down from that. Then the earth end is basically the top of the cable.
No, rocket price does NOT grow exponentially in the mass of the payload . That's obviously wrong since you can put 2x the weight of stuff in space simply by launching 2x as many rockets and you save money (in the limit) by combining them into one bigger rocket.
What you meant was it grows exponentially in the velocity to be achieved.
A rocket is just a really slow cannon
A rocket is the projectile, because the cannon stays behind after being fired.
And a rocket is pretty much a really slowly exploding bomb.
@丫o the rocket is the cannon, because the projectile is the Astronaut/payload capsule that leaves the rocket behind
Your butt is a really slow cannon
I hope they invent a anti gravity so it's easy to levitate (in my opinion). 😅😅😅😅
I think scientists could replace rockets with balloons to help out with the environment
I won't be investing in spinlaunch. There are physics issues that won't go away. Like precisely releasing a payload in a vacuum that then slams into, and penetrates, a metal portal, the rocket then hits the 14.7 psi atmosphere at supersonic speeds. All that to launch relatively tiny payloads into limited numbers of orbitals.
Shame we'll be extinct before we ever have time to try these for real...
