Energy recovery from community water supplies
Recovery of otherwise-wasted energy is becoming more important. The hybrid cars now on the market and an idea about placing windmills next to highways to be turned by the constant wind suggest looking into other sources. The constant water flow from municiple water systems and water towers could be used to drive turbines just as a hydroelectric dam, but to generate electricity on a smaller scale.
