HHO Dry Cells. Has anyone tried it?

Featured Replies

I was wondering if anyone has tried installing an HHO Dry cell into their car and what their experience was like?

 

Did you have to do any extra tuning afterwords?

What type of engine etc?

total cost of parts for install?

was it done by a mechanic?

Have any photos to post?

City AND highway MPG gains?

What is that? One of the 'brown gas' generators? The problem I see with those setups, is it takes energy to do electrolysis on the water to separate it into hydrogen and oxygen. So that gets recombined in the engine, which does release a lot of energy, but not more energy than it took to do the electrolysis to begin with, which, being that the alternator is providing that power, is far less than 100% efficient. Any 'efficiency' gains by mixing the gas with gasoline while burning I think would be more than lost by the inefficiency of electrolysis and extra weight in the vehicle of the equipment and water.
