A great deal of electricity is already provided by the movement of water in hydroelectric power plants. Usually, large turbines are placed just after dams or under waterfalls that spin as the water rushes past at high speed. There are other ways to generate power from the movement of water, though, and automotive supplier Continental is providing its expertise towards that goal. The supplier's ContiTech subsidiary is drawing on Continental's vast experience with rubber for the project, which pla

The strong tidal currents flowing in and out of San Francisco Bay used to be one of the deterrents to prisoners trying to escape from the prison at Alcatraz by making it extremely difficult to get from the island to the mainland. Soon, those same currents may be put to use to provide electricity to communities in the Bay Area. Pacific Gas and Electric Company is teaming up with San Francisco and Golden Gate Energy to examine the viability of installing tidal power generators in the water to harn

Starting August 20th, Marine Current Turbines will install the worlds largest tidal current turbine in Northern Ireland's Strangford Lough. The 1.2MW turbine will be the first commercial scale underwater turbine powered by tidal currents. The system will generate enough electricity to power 1,000 homes.

One of the complaints about using hydrogen as a fuel, or more accurately as an energy storage medium, is that the energy required to produce hydrogen, exceeds the energy output. If hydrogen is being produced via electrolysis powered by fossil fuel electricity, this is a very serious issue. However, if you can find a pollution-free means of powering the electrolysis process, you can largely overcome this. An inventor in Houston, Texas has developed a mechanism that uses wave power to generate ele
