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.

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.

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.

Advancing Technologies Harness the Power of Wind, Water, and the Sun
Posted in Hydropower, Solar Power, Wind Power, Renewable Energy, Features on
Friday, July 10 2009
Renewable energy will be the world’s
fastest-growing source of electricity
generation over the next two decades,
although it will still make up a relatively
minor portion of the global energy supply,
according to the Energy Information
Administration. The majority of that
increase will come from the use of wind
power and water power, or hydropower.

NASA Energy Concept Could Harness the Power of Ocean Waves
Posted in Hydropower, Renewable Energy, Features on
Thursday, June 25 2009
NASA Jet Propulsion Laboratory (JPL) researchers who
developed a new way to power robotic underwater vehicles
believe a spin-off technology could help convert ocean energy
into electrical energy on a much larger scale. The researchers
hope that clean, renewable energy produced from the motion
of the ocean and rivers could potentially meet an important
part of the world’s demand for electricity.
