I’m no billionaire industrialist, and I don’t pretend to know anything about the Kantrowitz limit, but I do know about some of the topics touched on in the Hyperloop proposal, and since I’m paying for this blog, I might as well use it.
And the end:
I’m not saying that the problems with Hyperloop can’t be solved. Money, time, and talent can solve any problem that doesn’t involve breaking physical laws, but I wouldn’t put my money, time, or talent in the hands of someone who takes me for a fool.
The stuff in between those two statements are pure gold. I actually didn’t read anything about the Hyperloop — it sounded stupid to me — but man did I love this from Dr. Drang.
