Forgot to mention, forget about the hydrogen in terms of the Joe Cell.
If the Joe cell works, hydrogen and oxygen are just by-products. In 10 minutes the Joe cell wouldn't make enough hydrogen to blow your hat off!
That's not to say its doesn't work, just that if it does its using some other form of energy.
Problem is, just like Meyer, you can read a whole lot of nonsense and contradictory statements about the Joe Cell. Most of it from uneducated people without a clue. There are even the religious crackpots who seem to think that a god makes it work, and it only works if you think 'nice thoughts'.
