Clothes dryers are one of the biggest energy users in the home, but a new discovery made by scientists at Tennessee’s Oak Ridge National Laboratory could change the home appliance’s energy-guzzling reputation forever. This “dryer of the future” will extract moisture from clothes using ultrasonic vibrations rather than heat. This method will not only use significantly less energy, but can also cut down drying times for a full load by as much as 15 to 20 minutes.
