ACCRC for running his Lincoln on aluminum soda cans. They threw
this rig together quickly to test the concept. The concept
works. Here's how it works. Soda cans are dumped into a tank of
Lye (sodium hydroxide and water). The sodium hydroxide peels off
the aluminum oxide surface from the aluminum allowing water to
come into contact with aluminum metal. The aluminum immediately
oxidizes, ripping the water's oxygen atoms away to make aluminum
oxide. That releases the hydrogen which bubbles out to be burned
in the Lincoln's engine. Here's the reaction: H2O + Al -> AlO2 +
H2 + heat Step 1: Lye tank and water bubbler His left hand is on
the hydrogen vent hose. The gas that bubbles out of it is hot
and steamy and has a fair amount of powdery white aluminum oxide
in it. So next it goes into a pipe to the bottom of the white
bubbler tank, where it bubbles through water. That makes it cool
and clean. Just like in a hookah or bong.
