Considering you'd have to completely submerge your dishes, I don't see this thing saving any water. I'd be interested to see the energy comparison of ultrasonic vs. heating water, but it might not be as much energy savings as you'd like.
At least it doesn't need soap. Actually, I wonder how soap would react in an ultrasonic bath. Bubble city?
@WMyers: I clean with ultrasonics almost everyday, and the parts need to be very clean.
Using a soap is necessary to remove particles. Adding heat helps also, basic chemistry/physics. You would need something to act on removing the grease from the dishes. The ultrasonic is very good at providing essentially agitation to do the work, but you are really hurting yourself if you don't have an active chemical in there. Soap is one thing that helps remove grease also, soap is a surfactant. You should be able to use a lot less soap though than a traditional dishwasher.
We used large one's to clean pistons that came off a ferry i worked on. It wasnt really that loud but the cleaner was in the engine room, worked a real treat.
Seems you need generous open space in the kitchen in order to take full advantage of this thing, in which case, such space could accommodate dedicated (and better looking) traditional kitchen furnishings. Humbug, my good man, humbug indeed.
I am all for untilitarian and stark (I LOVE stainless steel and glass), but this doesnt seem practical for a home. In most family homes, the kitchen is everything from office, to lounge to command center and this doesnt have that friendly, inviting family gathering appeal.
@Geisrud: I've heard of chicken & waffles. I do watch the food network ;c) I've just never personally eaten chicken with my waffles. It sounds weird. Though I could be missing out on an amazing combination.
Next time I make waffles, I'm frying up some chicken.
