"As has been stated before, energy is not used up, it is transfered.
Is it stealing energy? It could be looked at that way, but it's not really."
A pound of water has 2/3 pounds of hydrogen.
Let's assume that 2/3 pounds oh Hydrogen when ignited along with 1/3 pound of Oxygen will burn and yield 1,000 Watt Hours of energy.
If you could gassify the hydrogen using 1,500 Watt hours of electricity and then burn it all you would be able to measure the Watt hours that it produces. Again, it will be 1,000 Watt hours.
Can you obtain more calories from a pound of water than are in the water to begin with? Of course not.
Can you unburn the water using electrolysis with less energy used to make it?
Of course not. That would be OU.
