I drove 1800 miles in a Hydrogen Car

Hey, I just wanted to add some fun facts.

There's been a large push for hydrogen cars in the nordic countries, especially in Iceland. There they had hydrogen buses prior to the financial crack in 2007, and I think they're still trying to get it running fully. Thus hydrogen cars actually predate the modern battery EV.
There's a lot of research going into increasing the hydrogen density (you could look at Torben Jensen from Aarhus university)
The hydrogen is produced via electrolysis. and was originally thought of as a way to store the power generated at night (in Denmark it's a common occurance that our wind turbines generate more power than we can use at night. We often pay Norway to use it to pump water up a mountain (as a battery), but it would be more efficient if we could just store the power ourselves)
There's also a lot of research going into producing H_2 directly from the sun (photocatalysis), that way you'd be able to skip the electrolysis.
