An RC Car That Runs On Soda Can Rings

polyp2000 writes with an Engadget excerpt to inspire instant toy envy: "A pair of Spanish engineers have recently unveiled the dAlH2Orean (see what they did there?), a R/C car that runs on aluminum. Dropping a few soda can tabs into a tank of sodium hydroxide produces enough hydrogen to power the little speedster for 40 minutes — at almost 20mph."
