Elon Musk: Why I'm Building the Starship Out of Stainless Steel
- rekshaw 8y agoI know he's not a perfect human being, but damn do I enjoy people that speak clearly, logically and challenge assumptions.
- ddingus 8y agoI do too. If we're going to give people the opportunity to obtain vast amounts of wealth, I really prefer they do these kinds of things with it. And not just big picture space Tech things. Just the idea of very big risks. Go big or go home kind of work. Elon does that, and he does it because it's his passion and he's good at it, and he thinks he may succeed. Others could be doing that, or empowering those who can. There's a lot of this big work to be done. And we cannot take it with us. Might as well put wealth to use right now make a difference.

I would triple-check my calculations. If that fuel ignites, the net effect may not be cooling.
- tomatotomato37 8y agoCyrogenic fuels are cold, and they have a lot more heat density than atmospheric air; that's why you have those pictures of icicles forming on running fuel-cooled cyro engines. The problem though is that I don't think SpaceX uses cyro fuels
- gmiller123456 8y agoWhile I think it's great Musk puts his money towards such things. My main worry is that he'll be bored with it, sell off all the tech secrets and patents to patent trolls, and set us back more years than before SpaceX came about.
