Submission + - Dyson Unveils New Bladeless Fans to Replace AC (inhabitat.com) 2

An anonymous reader writes: Sir James Dyson, of vacuum fame, has just unveiled two new bladeless fans that work upon the same principle as a jet engine, sucking air into a cyclone accelerator that amplifies it 15 to 18 times before blowing it out over an airfoil-shaped ramp. The new units significantly upgrade the diminutive scale of their previously unveiled Air Multiplier, making them "the opening salvo" in the inventor's "war on air conditioning". It's a valiant effort, considering that the average American household already uses 2,822 kWh of energy each year to cool off, spending $276 a year.
