Racing to Canada in a Hydrogen Car

Of all the teams competing in the North American Solar Challenge, only the University of Missouri won't be bothered by cloudy skies. They're making the 2,400-mile run from Texas to Alberta in a car fueled by hydrogen.

Hydrogen? In a solar car race?

Yep. The school's built a lot of solar cars over the years and decided to try something different. Tigergen is a "demonstration vehicle" competing in the 10-day race just to show that hydrogen works. The way the team sees it, hydrogen cars makes more sense than solar cars.

"We didn't feel that solar is the most efficient fuel for transportation," team member Sarah Scully told Wired.com. The team entered the last Solar Challenge, she says, "and our car's whole roof was the solar array. It generated about as much power as a microwave."
