This is certainly believable but there always seems to be some sort of "secret ingredient" that is key to the operation.

For what it's worth, it would be a great idea but I'd like to know how long do those stainless steel plates last?

For something to be produced, something has to be sacrificed/consumed.

Perhaps so many plates per hour/day/week/month, etc. There has to be a measurement unit. More will hopefully come to light soon.
(if it was a real event).

This seems to be a basic but functional device, what it needs now is some refinement of the components/plates and voltage used on the plates.

It needs some serious optimisation but very cool indeed. 

At least that's how I see it.

I had just warched this video at You Tube,  I am not sure about this because it looks like he built it on a generator and
it is possible we are being tricked.  Water flowing could produce electricy I'd say  lots of Hydro electric generators around

Thought I'd open this thread again with this vid

Not sure if I saw that vid on here first. As far as I can tell it's a hydrogen engine with a combination of a hydrogen fuel cell and a water cracker to extend range.
Looks hopeful though
