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.
Step 2: Storage Bag
The reaction can take place at high pressures, so in future the lye tank and other parts of the gas generator will be pressure vessels leading into a high pressure storage tank.
Step 3: Engine Air Intake Duct
James has gotten the car to run on hydrogen concentrations between 5% and 70%, so
the mix is pretty forgiving. Here it's controlled by a tuna can resting on top of the aluminum duct tee.
In the future setup it'll be replaced by a proper butterfly valve to set the mixture to some optimum.
