Aquaduct Bike Purifies Water As You Pedal

Mike writes "Winner of the '08 Innovate or Die competition sponsored by Google and Specialized, the Aquaduct is a pedal-powered concept vehicle that transports, filters, and stores water. The design has massive implications for communities where safe and secure sources of drinking water are not readily accessible."

      The amount of additional cooling provided by the effective wind over the body is linear with speed. Drag, however, goes up by the power of your speed. So twice as fast uses four times as much power, while only providing twice as much cooling effect. Clearly this means that at SOME point your additional exertion is going to far outweigh your additional cooling and your body reacts by sweating harder. Its to no avail, of course, but that doesn't stop additional sweat from leaving the body only to drip.

      If you're not drinking enough fluid to keep your kidneys working you're getting dehydrated and your performance is suffering.
