Although the allures of heat transfer science might be remote for some, and frankly boring for others, would you want to know more if they could dry your clothes with less energy? Michael Brown, not of GE or any drying machine manufacturer, has come up with a way to make clothes drying less energy intensive. Instead of using a traditional air-in-contact-with-heating-coils heater, Michael’s uses an oil as the heat-transfer medium. The oil needs less energy to heat, and, once heated, holds onto the heat better. That oil is then used to heat the air that gets blown into the drying drum.
The device is so much more efficient that it can be plugged into a regular 110 V plug (instead of 220s now required by dryers.) Additionally, the heating unit only ever reaches about 150 F, since the heat-transfer is so much more efficient. Traditional dryers have to heat their elements up to 1000 F in order to reach optimal efficiency, resulting in about 15,000 household fires each year.
The device can be installed by a technician in 30 minutes at a total cost of around $300, which would be recouped in less then four years. It might also be the first dryer to ever receive an Energy Star rating.
