Clothes dryers are great, and a key part of modern life, but they do use a lot of energy.
"Early testing found ultrasonic transducers could indeed blast droplets of moisture away from fabric, effectively drying it. However, unlike heat, the ultrasonic field doesn’t effectively permeate through a pile of clothes, nor can it readily be used with a spinning drum to dry many garments at once."
But despite this, like may other ideas including batteries, maybe the idea has a lot of merit and needs to be developed further. It has the potential to not only use less energy, but also to cause less damage to clothes with the absence of heat.
I was certainly surprised to see how well an ultrasonic cleaner could just clean some hardware items I put through mine.
