Techno-geeks unite! General Motors has been pushing the idea of a hydrogen powered car for a generation. Now we’re getting somewhere. True, making hydrogen for fuel cells at the moment uses a lot of energy, but, interestingly, it generates a lot of energy once you do it. Far more than it takes to run a car, for example. If we could harness that extra energy, perhaps the transition to hydrogen as a fuel for vehicles could be well worthwhile. If only because the exhaust is….water vapor.

Here’s a video (thank you, Joe!) of what driving will look like in the (surprisingly near) future.
