The car manufacturers have it wrong—we don't need hybrids or electric cars. We need cars that run on discarded junkfood containers—like the DAlH2Orean remote-controlled car! Two Spanish engineers from the Polytechnic Institute of Catalonia figured out a way to power the little car with soda can tabs.

The aluminum tabs are mixed with sodium hydroxide and water to create a small hydrogen fuel cell that emits zero CO2 emissions. The little skamp can go 20 mph for 40 minutes, which is impressive when you consider that the Chevy Volt goes for about 40 miles on a charge. Wonder if they've considered soda-can tabs over at GM...
