The car manufacturers have it wrong - we don't need hybrids or electric cars. We need cars that run on discarded junk food 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 aluminium 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 32km/h for 40 minutes, which is impressive when you consider that the Chevy Volt goes for about 64km on a charge. Wonder if they've considered soft drink tabs over at GM...
