The Aqueon fireplace by Heat & Glo actually uses regular water to create fire.

Ordinary tap water (preferably distilled) is supplied to the fireplace through a pipe or tank, a 220 volt electrical service then separates the hydrogen and oxygen atoms through electrolysis, the Aqueon ignites the hydrogen, and ta-dah, fire! The oxygen is then added for color and brightness, while the rest is released into the room. It doesn’t require venting because it doesn’t produce any harmful emittents like carbon monoxide — just water vapor. And the whole thing is modeled to look like an artistic sculpture of a candle flame, which makes this thing all the more cooler… er… hotter.

No idea on how much this thing will cost, though apparently it’ll be out some time this summer. Now excuse us as we attempt to lift our jaws off the floor.
