A look at battery-less, mesh sensor nets
Ultra-low-power ZigBee-based wireless mesh networks, powered by a variety of energy-harvesting technologies, make it possible to create the first truly wireless and battery-less sense and control networks for regulating energy consumption in domestic and industrial uses.
Homes, offices and factories waste energy on lighting, heating and air conditioning. With the help of light- and temperature-sensor network technologies, energy conservation processes such as turning off lights and adjusting temperature now can be automated, reducing costs.

Why would anyone use an expensive, untried and complicated energy harvesting technology when a PROVEN 20 YEAR battery is available which is environmentaly friendly and inexpensive?
