Please explain how we "get hydrogen gas out of water".
And then you ask me when is the last time I took a physics course.
Yes, because it must have been a long time. So, how long ago was it?
please look at this article which is very real...hydrogen gas has been gotten out of water for sometime now. The problem has been the amount of energy it has taken to do that. Now, that problem has been solved by this company and inventor. http://www.spiritofmaat.com/archive/watercar/h20car2.htm
