From vaccuums  to kitchens , via fans  and bicycle wheels , Sir James Dyson  is the king of engineering  design and innovation. And now the British inventor has brought hot air to faucets, cutting down on the need for paper towels. The Airblade Tap  is the latest in his stable of hand dryers, a faucet-dryer hybrid, which is covered by 100 patents so far (another 110 are pending)--making the creation similar to  in some respects.
This new invention is basically a unit containing a motor, air filter, and sound-silencing equipment alongside air and water pipes fitted below a sink, from which a tap protrudes. Depending on where you place your hands, infrared sensors determine whether you seek wetness or dryness. Stick them in the center beneath the tap, and you get water, move them to the side and you get air--more specifically, cold air that blows at 430mph, which is more than fast enough to dry your mitts. That is to say, it's about the speed, not the heat.
The secret lies in the motor, which uses an electromagnetic field  rather than carbon brushes to accelerate from nought to 100,000 rpm in 0.7 seconds , four times the speed of most similar-sized motors. There is, however, a rather large problem. While most hand driers retail for anything between $80 and $125, the Airblade Tap costs around $1,200. Are firms really going to spend that amount on a dryer? Dyson's thinking is that one blast from his invention is five times as efficient as a hot-air dryer, and 15 times more efficient than paper towels, so, eventually you'd save money. Eventually.
