Liquid Hydrogen had nothing to do with the shuttle explosions. I am not sure what he means by touting the deaths of those astronauts.
When you are dealing with the smallest atoms in existence they are going to leak through EVERYTHING. We see things as “solid.” When you are an H atom, nothing is solid…there are spaces between everything.
You’re two paragraphs contradict each other. Which is it?
The external fuel tank, rather than the fuel it contained, was the weak link in the system. It was parked right next to the SRBs with their unreliable O-rings, and was cold enough to shed chunks of ice onto the fragile shuttle.
Yeah, talking about deaths in a discussion about H is misleading and conflation — a typical commie trash trick that he should be ashamed of.
As you say, H is horrid in that it penetrates everything. What is worse is that when you find something it can’t leak thru (there are metals) it gets part way in and then embrittles the material.
OTOHand, it is ubiquitous. Just crack some water and you have fuel. Solve the storage problem and you don’t need many power distribution infrastructures. E.g., set up a solar panel for the leccy to split some water out of your house’s hose tap — voila, fuel for your car.
And, it is really cold too. I partook in handling a few gallons over the years. 😳🤔😂👍
