You know how public restrooms make the practice of drying your hands rather unsatisfying? Well, James Dyson, of the Dyson vacuum empire plans to change all that. His newest invention, the Airblade, is a sleek high-tech wonder that conserves over 80% of the energy wasted on the old hot air machine. It works through a sensor and blows room-temperature air at 400mph. You don't have to touch anything, your hands get pleasantly dried, and while all this is going on, the machine is sucking dirty bacteria out of the bathroom! If you want to get one for your apartment, they will go on sale in the UK for about $1000. If you just want to try it out, they will also be available for lease.
