Mechanical Extraction of Power From Ocean Currents and Tides
Posted in Hydropower, Energy Storage, Renewable Energy, Tech Briefs on Wednesday, March 03 2010
NASA’s Jet Propulsion Laboratory has proposed a scheme for generating electric power from rivers and from ocean currents, tides, and waves that not entail the high maintenance costs of other schemes that call for submerged electric generators and cables.

Using Aerospace Approach, Engineers Design Wave Energy System
Posted in Hydropower, Wind Power, Energy Efficiency, Renewable Energy, News 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 Hydropower, Energy Storage, Batteries, Renewable Energy, News 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.

$32 Million Initiative to Expand Hydropower
Posted in Hydropower, Renewable Energy, Government Initiatives, News on Wednesday, July 15 2009
U.S. Department of Energy Secretary Steven Chu announced up to $32 million in Recovery Act funding, which is designed to support the deployment of hydropower turbines and control technologies to increase power generation and environmental stewardship at existing non-Federal hydroelectric facilities.

Virtually Engineering Energy Conversion Plants
Posted in Biomass, Hydropower, Solar Power, Wind Power, Renewable Energy, News 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.

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.
