Clothes dryers in the United States use about as much energy each year as the entire state of Massachusetts, according to an estimate from EnergyStar, which is part of the reason the Department of Energy is trying to develop more efficient home appliances.

Among those making significant progress is Ayyoub Momen, a staff scientist at Oak Ridge National Laboratory in Tennessee.

Like most Americans, he owns a dryer. But he says he hates using it. He knows it's an energy hog, and it takes so long to dry anything.

Then, one day, he was thinking about ultrasonic humidifiers — a kind of portable room humidifier that uses high-frequency vibrations to turn water into steam without getting hot. And Momen thought: What if I use the same technology on a piece of wet fabric?

“The result was so amazing. It was, like, mind blowing," he says. "In less than 14 seconds, I could dry a piece of fabric from completely being wet. If I wanted to do the same thing with heat, it’s taking somewhere between 20 to 40 minutes."

Momen’s current prototype looks nothing like a conventional dryer. It's basically a small circle of metal called a transducer that he plugs into a battery. He then douses a small piece of fabric in water and places it on top.

What the hell is a "cloths dryer"?
We just hang our stuff on a line and let it dry naturally.

You say that like you don't understand the desire to make shit easier. Why spend a bunch of time hanging clothes up outside when you can just take them out of one box and dump them into another? C'mon, now.
