Such as? SpaceX and their reusable rockets might be the closest thing I guess. Tesla and his solar company use pretty conventional technology, on the other hand. He is willing to invest a lot of money, that's true. But when talking about the Hyperloop, it's hardly just his money that's at stake if government is supposed to be involved.
>What's that network you're using to blast this tripe straight to my eyeballs right now?
A network that evolved from humble origins decades ago. Maybe if Musk financed a hyperloop prototype in the desert for a decade and showed its economic viability, then you can make that comparison. But who knows, maybe that's what he plans to do with the government approval he's supposedly gotten - good for him then, hopefully it works.
