Using Aerospace Approach, Engineers Design Wave Energy System
Posted in News, Wind Power, Energy Efficiency, Renewable Energy, Energy, Hydroelectric Power, GDM on Friday, November 20 2009
Aerospace engineers from the U.S. Air Force Academy are applying the principles that keep airplanes aloft to create a new wave energy system that is durable, efficient, and can be placed anywhere in the ocean - regardless of depth. While still in early design stages, computer and scale-model tests of the system suggest higher efficiencies than wind turbines.

Harvesting Energy from Regular, Day-to-Day Motions
Posted in News, Batteries, Electronics & Computers, Energy Storage, Renewable Energy, Energy, Hydroelectric Power, GDM on Friday, October 30 2009
Duke University engineers have developed a novel approach that they believe can more efficiently harvest electricity from the motions of everyday life. Although motion is an abundant source of energy, only limited success has been achieved because the devices used only perform well over a narrow band of frequencies.

Virtually Engineering Energy Conversion Plants
Posted in News, Biomass, Solar Power, Wind Power, Renewable Energy, Energy, Hydroelectric Power, GDM on Tuesday, July 14 2009
Photovoltaic and wind energy plants, hydroelectric power stations, and biogas plants can be complex to design and maintain. In designing a hydroelectric power station, an engineer needs to know what the pressures, temperatures, and fluid flows will be in the facility. Virtual reality makes planning and operation easier.
