You really can drive across the country on algae--and a 700-pound battery pack--or so proved the crew behind the documentary Fuel . Embarking on September 8 and pulling into New York City today, just in time for the film's premiere, the Algaeus covered 3,750 miles.
"It got 147 miles per gallon in the city," says Fuel director Josh Tickell of the converted to plug-in Prius hybrid that he drove on a mix of battery power and algae fuel blended with conventional gasoline. The Algaeus did less well on the highway: 52 mpg, because of the lack of regenerative braking that recharges the battery, among other things.

Toyota won't just be adding solar panels to its popular Prius gas-electric hybrid car—like the solar electric conversion kit seen at left—it'll be powering a version of it exclusively via sunshine, according to The Nikkei, Japan's business newspaper. In fact, Toyota will be relying on the solar-electric car to "turn around its struggling business," which resulted in its first operating loss in more than 70 years, the Associated Press reports.
ScientificAmerican.com and other media outlets reported last summer that Toyota was planning to begin selling a Prius with some solar panels as early as May of this year. But the latest reports are that the Japanese automaker is seeking to build a totally solar-driven vehicle.
