Using Nature To Clean Water
Nature moves in spirals, from whirlpools to hurricanes to the human heart. Scientist Jay Harmon spent 20 years working to "freeze" a whirlpool so that he could reverse-engineer it as the rotary part of a machine or pump. This "frozen whirlpool" can stir 10 million gallons of water in a storage tank for the equivalent of a couple of light bulb's worth of power, keeping the water clean without the use of chlorine or other chemicals. This design is now being used for other applications, including fans, propellers and wind turbines.
