Excellent video sir. Thanks. God bless you and your team.

The explanations has been really great. I think that with small improvements, they could have been even better. For example, showing how fuels are mixed by the injector plate and burnt should be before the explanations of the pumps. This way the trick of cooling the combustion chamber with liquid H2 comes before using it at the turbo pump. It would have been also better to show possible electric motors in operation pumping fuel, before replacing them with turbine. Aka, show the motor moving the impaller, then keep the impaller in place and replace the motor with turbine. This way, even visually, there could be no doubt which part is driving the motion. Also, You said that you are giving example with the H2, but it would be nice to have a label on the screen. Especially when you need need two of them for the gas generator. Once again. Your videos are probably the best explanations I've seen so far.

Fact: Fuels with less maximum theoretical efficency tend to have larger density, so that's why you can see a Falcon 9 (22,000 kg to LEO) , using subcooled RP - 1 as fuel, would be much smaller than, say, a Delta IV Heavy, having more than double the size of fuel tanks (using LH2) while can only carries a little bit more payload (23,000 kg). (Note: To those of you who said that the Block 5 Falcon 9 actually only have 13,000 kg as LEO payload, remember that this rocket is partially reusable, and the first stage had to perform the slowing burn upon atmospheric reentry, plus a suicide burn to have a soft landing, so yeah.)

However, this video makes it sound very much like there is a lot of secrecy going on in the domain of these propulsion systems. In a global society, I don't see the merit in that when we are talking about technologies and projects that are too big to be developed by private companies anyways.

Aluminium Lithium alloy Space X - Hold our Starship

So, when I do the math on this, I find that a propellant tank with a volume of, say, 100,000 cubic meters would be able to store about 70 tons of liquid hydrogen. That exact same propellant tank would be able to store about 800 tons RP-1 and about 1100 tons of hydrazine. So it's almost a tenfold decrease in propellant mass for only a 25% increase in specific impulse. That doesn't seem ideal to me. What am I missing? Even when you plug in the rocket equation in the other direction, you find out that a rocket powered by LH2/LOX needs a propellant tank ten time as large to get the same total delta-V as one powered by kerosine or even methane. And the larger tanks just means a much heavier rocket, which is exactly what we DON'T want, isn't it?
