Reminds me of that vacuum clothes dryer:

Tumble Dry In Vacuum - Yanko Design
DryMate is a clothes dryer that uses a new vacuum technology to dry clothes at lower temperature. As a result lesser energy is consumed, and heat-related damage to the clothes is avoided. The dryer scores another brownie point for being easily accessible from a standing position. To aid its...
The knowledge about drying clothes...
They say "As we are not heating up the fabrics, we exspect less lint".
Well, as far as I know, heat and lint are only related in a really minor way. Mechanical action would be what has to be reduced to reduce lint.
As far as I know, the vacuum dryer technology was developed by a university in the swiss. It seemed promising and the first test (protocols can be found online) worked pretty well. The estimated that they could reach an A-50% (arround the 2005 mark, that was amazing) rating.
However, further tests proofed that the systemm was pretty expensive to build and as heatpump dryers started to get into the market, the development was stopped.
On that sonic technology,I can only say: They can dry 1 single layer of fiber in 14 seconds.
A dryer has to dry multiple layered clothing that moves randomly as evenly as possible.
As far as I understand the system, the laundry has to be in full contact with the drying surfaces. Now, for example, how will the pockets inside a pair of jeans get dry? Or simmilar?
And how about cats, or birds that may hear those ultra high frequencies?
A lot of great technology worked well in small scale. Like lifting cargos with multiple consecutive explosions.
How ever, scaled up, things looked different. That's why we never launched space ships with nuclear bombs.
(And yes, the U.S. made tests about that. I think it was called project Orion.)
