Arc-liberated chemical energy - this process releases enormous pressures and little heat.
This technique reminds me of an idea I had in the mid-1980s of developing a spark plug for automobiles that would dissociate water directly inside the cylinder thus providing power on demand from dissociated water. This process would avoid modifying the carburetor which is reportedly a federal crime. During the Swiss Association for Free Energy, 1989 in Einsiedeln, Switzerland I told Stanley Meyer my idea which conversation was witnessed by Jeane Manning who was sitting at the same table in a corner cafe. Stan went on to promote this idea without mentioned where he got it. I see others now promoting the same idea around the web.
