There's no doubt that solar energy is one of the greenest sources of electricity and the idea of using it to power transportation is not new. We've seen solar-powered boats and solar-powered cars before, among other things, but we didn't know until now that a solar-powered high-speed train was on anyone's drawing board. Apparently, it is.

Conceived as a means of zero-carbon high-speed mass transit, the Solar Bullet would travel between Tucson and Phoenix, AZ at 220 miles per hour, cutting travel times from two and a half hours (in traffic) to just 30 minutes. Taking advantage of the high amount of solar irradiance in the American Southwest, the tracks would be covered by a huge solar array to provide it with the necessary power. The SolarBullet Campaign aims to increase awareness and support among Arizonians and build a team of university experts, engineers and transit specialists to move this project further down the line. Feel free to hit them up on Facebook or follow their Twitter feed to offer your own encouragement and keep track of the initiative.
