Indian-American invents dryer that requires no heat

Waiting an hour for your clothes to dry can feel tedious when you need something in a rush.
But Indian-American research and development associate Viral Patel and his team of researchers at Oak Ridge National Laboratoryin Tennessee have developeda dryerthat couldmake doing laundry much quicker.
Called the ultrasonic dryer, it's expected to be up to five times more energy efficient than most conventional dryers and abledry a large load of clothes in about half the time.
"It is a completely new approach. Instead of evaporation, it's technically performing mechanical extraction of the moisture within the fabric," Patel told Knoxville News Sentinel.

Patel said that traditional dryers generally use straight-forward technology: as air gets sucked in from the surrounding area, it travelsthrough a heater or gas burner andinto the drum where the clothestumble around allowing the heat to absorbthe moisture with the air leaving the dryer.
However, the ultrasonic dryer usespiezoelectric transducers to removemoisture: when high frequency voltage is applied to the transducers, they vibrate at a high frequency causing trapped water to leave the fabric without heat.

Basically, the dryer shakes the water out of the clothes, speeding up the process.
Patel mentioned that GE Appliances is in the process of developing an agreement with the researchers to proceed toward commercialisation.

"We're trying to develop the technology that has efficiency greater than or equal to the state of the art but with a competitive cost, so it can be sold on the US market" because "if you walk into a big box store and you want a dryer, normally the first things consumers look for is how much it costs" and not energy efficiency.
"GE brings the expertise in that area, which we do not have," he added, stating that it will take at least two to five years before the ultrasonic dryers can be available in the market.
