Earlier this week, Honda began building the first hydrogen fuel cell-powered car for commercial use. In green-tech circles, this has become quite the big deal--not the least reason being that the auto's only emission is water. Oh, and did I mention that the car will get more than 70 miles per hour?
But even though the Honda FCX Clarity, which runs on hydrogen and electricity, is a study in how high tech is changing car design, it's not the only approach. Earlier, I spoke with CNET's Brian Cooley about what the future holds.
