Even RC cars are going green, check out this hydrogen powered RC. And it's really powered on soda can rings. Pretty sleek, don't you think?
You will see how dAlH2Orean
, can run a race.
The engine works like this: Sodium Hyrdroxide (NaOH) is a very strong base Ė itís incredibly caustic. Itís most commonly found commercially in an aqueous solution, meaning itís mixed up with water. And what you feed that solution something like aluminum, a soft metal that strong bases love to chew up, the aluminum picks up the oxygen atom from the Sodium Hydroxide, which then in turn replaces the lost oxygen by stealing one from the water in its solution. The result? Two free hydrogen atoms in gaseous form that bubble up and out of the mixture.
The process doesnít start until you add the aluminum, and with time the aluminum eventually dissolves and the reaction stops (or until all of the lye and water in the solution have shed their Hydrogen atoms.) Until then, you get the benefit of hydrogen being released that you can use to power an engine. In the dAlH2Orean, a couple of soda can tabs can get you a full 40 minutes of driving time at up to 20 miles per hour.
