Well, it made some sense, and adding O2 and H back with Fuel makes lots of sense, but $1000 is way too expensive, I'll try one when it gets down to $200 or less.
OMHO I beleive the technology has potential, but not cost effective.
We almost bought an ornimental fireplace that required a 60amp circuit to run the flame, and no chimney. but the flame was only about 12 inches high, out of a single dispursment, not worth the $5000 they wanted for the unit.
here's a quick link to one that came out in 2006 or so @ $50,000
