> At the end of the project, appliance manufacturers including GEA will be ready to invest in this technology and commercialize it. This will result in the U.S. becoming the leader in the clothes drying industry and generate new jobs and innovative applications of the technology. Pretty sure as soon as China is aware of this idea (if not already), they will have something in production and out the door faster and at…

Well I found this design from 2012: http://www.yankodesign.com/2012/03/01/ultrasonic-drying/

Looks Chinese to me.

One day we'll invent a technology device to answer the age old question: "Still wet or just cold?"

I press it to my face to answer that question. Somehow my face is much more reliable at telling the difference between cold and wet than my hands.

I just mentioned the "wet or cold" problem to someone else and they said "just use your face"! So it's not just you. Something to try this winter...

The demonstration seems to assume that physical contact is possible. For layered clothes it may not work that well, if at all. But! Even if we assume there's no progress in that area, I can still see this being used in an industrial laundry. I've worked in one and there are machines specialized for different types of garments. With automation, it may actually make economic sense. So while use in a consumer market may seem far out, industrial applications are still possible.

Ultrasonic Dryer? Who needs this? And DOE dropped nearly a million on it? Was it an SBIR grant with nice kickbacks? :-) I found a washing machine with ultrasonic much more interesting: http://www.tovatech.com/blog/3759/ultrasonic-cleaner/ultraso... http://www.huffingtonpost.com/2015/01/21/dolfi-washing-devic... Would be a little worried about stress on your clothes AND/OR Ears. http://www.sciencemag.org/news/2014/09/…

Maybe it will keep mice and bugs away while it is running.

It's not the fastest clothes dryer, but I often use one that runs on fusion in outer space.

Once both my kids wet the bed every night for a week. 3 loads a day. Even on a sunny day in Scotland a duvet won't dry on the line in 1 day.

I'm at the top end of Scotland - we can barely dry towels and trousers, nevermind duvets.

In Australia, that's very hard to achieve because the residential energy market is heavily regulated specifically to _avoid_ exposing low-end consumers to spot pricing.

In at least WA, NSW, QLD and ACT you can go on time-of-use residential tariffs. And driers (and washing machines - which use a considerable amount of energy particularly if they heat the water internally) typically already have timer-start functions.

Sure but time of use is _far_ less volatile than actual spot pricing. Hell, in WA and QLD it's not unknown for AEMO to post _negative_ energy prices.

Perfect, of course this exists. It even has a FUN button for when waiting for the clothes to dry gets too boring.

What really struck me as remarkable was this bit: "Digital display with back light gives exact and clearly reading although you stay at the somber conditions"

I wish my TV could do that...
