Hydrogen fuel-cell cars look to overtake electric autos
This is good because our batteries simply aren't very efficient at this point. They take a very long time to charge and don't go terribly far on what they've stored. I'd love to see better battery technology, too, but I suspect we'll never get as much out of batteries as we can from hydrogen fuel. To understand this visually, here's a graph of energy densities blog author Mark generated some time ago for a different purpose:
Here's a link that chart if you'd like to see it larger.
So, I'm excited to see that after repeatedly bashing our heads against the wall using old battery technology, we're looking toward a better solution.
