It would be great if some electrolysis (or equivalent) technology is developed that can extract more energy from the process than it consumes, but to date, I have yet to see anything close.

Power from water? That would mean electrical power plants located along coasts, too.

But hydrogen and oxygen don't like being pulled apart. It's certainly the "Holy Grail" of energy, and I like to be optimistic, but I'm skeptical that water will power anything more than my plants.

Also, given the astronomical gas prices, new scams are all over the Internet selling "water-powered car" plans, books, kits, etc, to a gullible audience.
