U.S. Researchers Develop Heat-Free, Ultrasonic Clothes Drying Technology

Energy.gov presents this video detailing a new approach to drying clothes that uses way less energy and time than conventional clothes drying, Via Core77

When I moved to Japan in the ’90s, the whole country was so hi-tech I felt like I was living in the future. Except for one thing: No one in my entire town owned a clothes dryer. My apartment came with a washing machine…and a bunch of rope and clothespins. My neighbor explained to me that since electricity in Japan was so expensive, no one used dryers when clothespins and patience could achieve the same results for free.
Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory also realize that clothes dryers are energy hogs, and this week they released a video showing a much more efficient solution they’re working on. Rather than using lots of electricity to create heat to evaporate the water, they use a little electricity to create sound. Specifically, ultrasound, using an amplifier. Aimed at wet clothes, the ultrasonic waves essentially shake the water droplets right out of them, enabling them to dry a wet rag in just 14 seconds!

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
