I am an inventor and I am working on a method of pulling the hydrogen directly and combusting it directly from water, with two additional compounds. My proto type will burn for hours in a small container with a continuous sound of small explosions. The question is "if I was burning the hydrogen directly from water how would I calculate ie, energy in energy out and efficiency".

The first step is to calculate the energy needed to produce the 2 other compounds. Many metals will liberate hydrogen from water. The trouble is, it takes energy to produce the metals. For instance, if you are using zinc, you would need to look up the heat of formation of zinc hydroxide. You also need to calculate any electricity you use.

Sounds to me like someone going for a `perpetuum mobile´.

No , actually what he is referring to is a Brown's Gas or HHO generator. There is extensive material on the internet about these dandy little generators. Many testimonials of people using them to supplement their gasoline use. Simple and VERY safe. The most common electrode is stainless steel... it appears to help electrolize the most hydrogen and oxygen. I am currently looking for anyone that any have personal experience using one of the devices.
