Another great video! I only know very very little about rocket science but have learned alot just from this one video. You mentioned not understanding at first how lower molecular weight creates higher specific impulse, and I don't know at all, but does it have anything to do with when propelling a lower mass molecule you "use/waste" less energy to propel that molecule than you would need to use to propel a higher mass molecule and the fact that you only have so much potential energy to begin with? Also would I wonder if it would be possible to carry water on board a craft, then use electrolysis to split the water into oxygen and hydrogen? Then the water would be potentially serving double purpose for fuel and producing breathable atmosphere on board? What little I know about electrolysis you would need potentially sacrificial anode and cathode elements and a certain ph/chemistry of the water to produce clean H and O. Oh I just remembered the water would need an electrolyte to be able to produce electrolysis, so that could interfere with getting pure hydrogen and oxygen from the water... Yea I'm really hoping you respond to clarify this. Again great video, great work and THANK YOU for producing great content.

questions: 1. why can't an electron gun like one used in cathode tube be used to provide thrust? in that case there would not a need for a propellant. 2. fission reaction releases neutrons at speeds around 20000 km/s. can't that be directly used to provide thrust?

Instead of using a typical nuclear reactor, a molten salt reactor would allow one to extract the xenon and krypton, which are part of the products produced during radioactive decay. This would allow a reduction in the fuel carried in the rocket for an ion drive.

There are ways to store the hydrogen to only be released with heat. Also, the government has particle colliders that we use to make the shells for nuclear weapons that give them ability to sit in hellish conditions without failing to protect contents. The solutions are already mastered.. We are the Borg, and while you destroy each other we will be using Elons neural tether to do exactly what he said he made it for. To link our minds to AI to remove ANIMALS from control. 100 thousand years of this mess is ENOUGH..

Xenon and krypton are produced as byproducts in nuclear reactors. In traditional solid fuel systems they creat intense pressures inside the fuel pins. A big problem. Molten salt reactors allow these gasses to harmlessly escape the reactor core. They are collected for commercial use.

We don't need higher impulse engines. We need less limited thinking like in this video. Was the ISS assembled in a single launch? No. Then why is it assumed a Mars flight can only be fueled by a single heavy lauch? Jesus....just carry as much fuel as you need to get to Mars in pods in multiple launches. My dads truck can do this...why not a Mars flight. Musk shot his stupid car past Mars. But we can't make the conceptual leap to carry up fuel for a Mars mission in multiple unmanned launches. Also. Gravity simulation can be achieved via connecting two capsules with a long cable and spinning them. Easy enough. We don't need to torture astronauts with long months in zero g.

3:12 You dont need fuel to decelerate when landing on Mars. Mars has an atmosphere wich can take over the role as energy absorber (eg heatshield). This logic applies to all planets and moons with an atmosphere (Earth, Venus, Titan)

---Is it hard to make ion thruster? NO You can make DC plasma in the Vacuum chamber and shoot the ions out through the biased grid in the rage of KiloVolts. ---So why everyone's not making one? BECAUSE It is extremely hard to direct the ion trajectories towards the axial direction and get that theoretical perfect specific impulse. The repulsion among ions, chaotic magnetic fields due to accelerating charges, neutralizing the propulsion chamber, and many more that I don't know yet are just the tip of the iceberg.

Liquid Hydrogen is obviously best for nuclear-thermal propulsion. But SpaceX is shortly to be the world leaders in dealing with liquid methane. If the reactors could be powerful and light enough; CH4 should be able to achieve nearly 600 seconds specific impulse, which isn't lousy. LH2 needs huge, heavily-insulated and actively cooled propellant tanks (for long term). The same size tanks could hold a *really* big quantity of sub-chilled methane. On that basis; using CH4 might be an excellent compromise. But then; so might anhydrous ammonia.

To store hydrogen use water. Electrolyze water and you have oxygen to breath and hydrogen to exhaust. excess oxygen or CO2 could also be exhausted. Now add carbon as a solid or powder and you could make CH4 or any other hydro carbon. you have high power thrust when you want. You have coolants, you have a myriad of options.

What we need is nuclear power from fusion. Well, it is here in the form of the SAFIRE GENERATOR. Almost costless electricity and therefore hydrogen from new fusion nuclear is now immediately upon us. We have recently taken a new step to advance the physic of power production by enabling chemistry of the atomic nucleus, or "nuchemy" in the newest FUSION NUCLEAR POWER technology of the SAFIRE GENERATOR. We are passing the chemistry level where we interacted with the atomic electron shells and are moving on to manipulations in this "NUCHEMY" atomic nuclear era when we interact and multiply nuclear protons. We have rediscovered the lost work of the alchemists and can make new elements with different atomic weights. This was ably demonstrated in "The Safire Project". Quanta are important. We now have enough energy in them to manipulate the atomic nucleus much more easily by creating a compartment, or what is a local region of plasma containment so reactions at this atomic nuclear level can easily take place. This is about to practically enabled a really fantastic and cheap new era of energy production for the whole of mankind. This with hydrogen, so free fuel obtained from water or atmospheric moisture anywhere in the world. This new fusion nuclear is at the industrial commercial production final development point as of now. The energy argument and other power methodologies are all now virtually irrelevant as we have new and very physically and economically powered practical and local community level fusion nuclear power. Solar roof plus Teslawall battery may be the present way to go domestically but megapack batteries and multiple storage technologies interconnected with an expanded ugly grid have a less certain requirement when you consider new any-scale community based and 24 hr reliable and self-fueling fusion nuclear in the form of the "SAFIRE GENERATOR". Learn all about it at "aureon energy.com". Learn the newer EU Theory and plasma physics at "Thunderbolts Project.com" and you will be permanently reeducated with this advanced new EU theory that will allow you to understand more about the astrophysics of our whole universe and all within.
