“Couldn’t find the address” with Safari and the .io App wanted my Apple Password and would not accept a fingerprint (No thanks). You’ve probably pulled this one down by now, but it’s one I missed and hoped this shortcut could save me from surfing.

2022-06-22 18:09:28 +0000 UTCWhat an awesome video! Not that I expected anything less though :) I am preparing a lecture for our local astronomy club on the exact same topic. My animations are just a tad less impressive :P

2022-04-28 06:58:31 +0000 UTCThis is an amazingly well organized and produced video that should be used as an educational video for budding rocket engineers. I agree with Daniel Miner. Your production quality is professional quality suitable for commercial use and sale.

2022-04-26 19:06:14 +0000 UTCI'm going to somewhat eat my words on hydrogen gas pressurization. It is being done, and the technical problems are being worked out. So maybe hydrogen could be used. 670 bar = around 10,000 psi. Technology improves. https://www.energy.gov/eere/fuelcells/high-pressure-hydrogen-tank-testing
2022-04-26 18:50:18 +0000 UTCThe problem with hydrogen is that it acts as a Lewis acid, so it wants to accept electrons. That means it eats metals, and even glass. Hydrogen is also so small that it will leak through any seal. Hydrogen is all but impossible to pressurize. It can be stored in tanks in liquid form, and as long as it is liquid it is minimally corrosive. On top of that, there are pretty high boil-off losses, and LH2 temp is 20-30 Kelvin. Liquid methane (methalox) is liquid at 91-112 K. This is why methalox is preferred over LH2. It's roughly the temperature of liquid oxygen. LOX. Hydrogen and metals. https://www.azom.com/article.aspx?ArticleID=104
2022-04-26 18:41:48 +0000 UTCThe "why don’t rocket engines melt" does not work. error message says the video is not supported.??

2022-04-26 18:04:19 +0000 UTCTim, Great video. Thanks for all you do.
2022-04-26 18:02:16 +0000 UTCFrame.io stopped working on my phone. At 3:00 - PRINCIPLES not PRINCIPALS. Mnemonic: "PrincipLE = "Law of Engineering", PrincipAL = "ALmighty".
2022-04-26 16:26:16 +0000 UTCIt's amazing and impressive how much your production quality has improved over the years. Thanks Tim!
2022-04-26 03:41:41 +0000 UTCExcellent video as always
2022-04-26 03:39:11 +0000 UTCThe animations are spectacular. I found myself pausing on each one to follow through with the descriptions and they always added to understanding. Nice work!

2022-04-26 03:01:43 +0000 UTCOh dang sorry I missed it! My brain must’ve been distracted trying to think through those awesome diagrams 😂
2022-04-26 01:34:20 +0000 UTCThere were clips from the Elon Interview in it!
