I want to see a study done on such a devices safety. The sound waves it emit are able to desiccate clothing. What is the effect of these sound waves escaping the device? Would it desiccate living tissue?

#152And how will my cat react to this thing? Something with enough sonic energy to vaporize a significant volume of water is probably loud enough to wake every animal in the area.
Looks like they calculated the optimum as ~500-600 Hz? That's in human hearing range too.
To get the effect they want they have to use high frequency 30-40kHz (as in name, ultrasound). They modulate it with lower frequency (which probably splits off bigger water globs) for better efficiency or something. You won't be able to hear the modulating signal as you are not able to hear the carrier frequency.

#153I sincerely hope this is no vaporware...

#154It's not the fastest clothes dryer, but I often use one that runs on fusion in outer space.
For apartment goers (or those that live in uncooperative climates) the reliability of such a system is a bigger problem than the speed. But for those that can use it, it is indeed a great system.
I used to hang my clothes indoors when I was living in Europe (some apartments had clever retractable hangers built above the bathtub), and even when raining they would dry in less than a day.

Probably the same ultrasonics hat are used in humidifiers. Hint, they don't travel far.

Lucky you. Try doing that in Chicago or Miami and your clothes will stink like holy hell thanks to the humidity.

#157If these go mainstream it would be thousands of times more handy to the small shop then for cloths. Vibratory cleaners with that kind of volume are crazy expensive!

> The idea sounds pretty neat but I wonder about longevity of the piezeoelectric transducers. If they'll wear out fast it's entirely feasible to design the dryer around user-replaceable piezos. It may end up like with inkjet printers -- where the dryer itself is just a boring spinning drum with a fan and a moisture collector and a powerful piezo driver, and you end up buying consumable cassettes with the actual trans…
You know what I want? A lemon law that states that major appliances need to run forever. Literally something that says, "This device must run without professional service for 25 years." Forget energy star stuff, 100Kwh saved a year is meaningless because we can always optimize powerplants. Stop building disposable 100LB metal boxes that have to get scrapped and thrown in a landfill. If the device fails earlier than t…
First you need engineers that can design appliances that, even if warrantied, do not need service within 25 years 100% of the time.
Perhaps they can be legislated into existence... ;)

If you use an air conditioner, you can do it the Chinese way. In humid cities people hang their clothes near the AC exhaust, since it is "free" hot air. In a super humid city I've seen clothes dry that way in only a few hours.

#160> 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…
even if they found out about it on the day of release they'd still out manoeuvre their American counterparts because.. cost.
