The only way we make hydrogen a primary energy source is if we solve our 1 Cubic Mile of Oil per year problem and go oil (and natural gas! Usually left out of the equation) free.

That solution requires over $100T of nuclear investment in today's dollars.

The work required will take nearly 100 years by current estimates. The massive uranium mines we need to build won't be pretty either.

When we do that? I think we will have hydrogen cars. It would be the only responsible way.

I hope we get a real energy breakthrough in my lifetime.
