Eh? Now who's talking drivel?

A fuel cell that magically splits water or in some other way converts
*only* water into electrical energy? This greatest, most fabulous
discovery was made a few years ago and nobody has heard of it?

This one perhaps?

"Fabulous" seems like an apt description, stuff of fables.

That looks like it. I only recall the publicity of its launch and didn't
follow up on what happened to it. However, MIT and Stanford University
have both demonstrated low energy water splitters that can run from low
voltage sources.

well I am sorry, but unless the laws of physics have changed the energy
required to split a molecule of water into hydrogen and oxygen is the
same whatever method you use, and about three times what you are likely
to get back recombining them to make mechanical or electrical power.
