Although hydraulics suits vehicles that make frequent starts and stops, thus enabling higher regenerative braking and energy storage, many think a hydraulically powered car is the way to go. One such group is Lightning Hybrids, Loveland, Colo., which expects to manufacture a fully hydraulic hybrid vehicle by 2010.
A pumped storage plant uses hydro technology to store energy generated by other power stations. Storage is achieved by pumping water from a lower to an upper reservoir. The …
Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively consistent source of …
