Soda Can Hydrogen Generator for Alternative Energy

Step 3The Reaction

The Reaction
Drop the activated strip in water. Watch the aluminum as it is converted into alumina and hydrogen bubbles off.

the reaction is 2Al + 3H2O --> 3H2 + Al2O3 + heat

Collect the hydrogen to run your car.

Ignoring all of the obvious problems with just telling people to go run their cars off hydrogen:
If you were planning on using hydrogen as a fuel source, why not just use electrolysis?

What about doing the electrolysis on the ground and the aircraft only carries the fuel? Especially since your own updates indicate gallium would be dangerous to have on an aircraft.

Eagle Research has a book with detailed information on building a Brown's Gas (oxyhydrogen) electrolyzer at various scales.

Have you used this to run an engine? I'm curious as to what the output is. Would it be possible for you to do a write up on the cost of this method as compared to using gasoline? Also is there any use for the alumina?

There are many variables in running a vehicle off hydrogen, for one, running a normal car, straight on it, would melt the engine.
Even mixing it with the gas, in newer cars at least, gives you a rich mixture, which can actually bring down your mileage. :/
There are many sites solely dedicated I suggest you explore if you already haven't. :)

You ned to look at it this way - A 1 litre engine running at 40 MPH at 40 MPG is using 4.8 liters of fuel per hour. BUt that is a liquid and much more dense than a gas such as hydrogen. The problem is storing enough to get any distance let alone the issues of storing a gas nder pressure.

Hi
I have a small question.
Are there any rechargeable/refillable Hydrogen fuel cells having same power specification and size specs as a AA battery?

another way to make large amounts of hydrogen and oxygen is to put steel into acid in a bottle with a balloon on the top or something
