The Bouguer anomaly map was used to identify areas where the Earth's crust is particularly...

ESA's Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite might have burned up in Earth's atmosphere back in November 2013, but the wealth of data gathered by the probe before its demise is still being utilized to great effect. A team of scientists has used the readings to produce an online tool designed to make it easier than ever to locate potential geothermal energy extraction sites.  Read More

Like a mini power plant, this electric vehicle can bid on energy in California's wholesale...

The California utility, San Diego Gas & Electric (SDG&E), has begun bidding energy resources from fleets of electric vehicles and storage systems into the state’s wholesale power market. The pilot program, one of the first of its kind, is meant to provide insights into how electric vehicles and other kinds of distributed energy resources can make the grid more reliable and efficient.  Read More

A metallic nanocoating derived from a virus of the tobacco plant could lead to more effici...

Researchers at at Drexel University have developed a metallic nanocoating derived from a virus of the tobacco plant that could lead to more efficient steam production, improving the performance of steam turbines, air conditioning and electronics cooling systems.  Read More

The BHO3 concept tire uses a thermo/peizoelectric net to turn heat and motion into electri...

One of the biggest hurdles that electric cars face in going mainstream is range anxiety – that dreadful realization that you're in the middle of nowhere and your car might not reach the next charging station. To help combat this, Goodyear came up with its BHO3 concept tire, which generates electricity by converting heat and motion into current as the tire rolls ... and even when it's standing still.  Read More

In the future, simply running while wearing your favorite hoodie could be sufficient to ch...

We've already heard about how thermoelectric or piezoelectric clothing could be used to generate electricity for our mobile devices. Now, an international team of scientists has successfully used special fabric to serve as an electricity-generating triboelectric nanogenerator. The research could pave the way for clothing that charges devices simply by moving.  Read More

The ultimate goal of the project is to relay power from orbit thousands of miles above Ear...

A successful ground test of a system designed to ultimately collect solar power from orbit and beam it back down to Earth was announced in Japan this week by Mitsubishi Heavy Industries. The wireless power demonstration saw 10 kilowatts sent over microwaves from a transmitting unit to a receiver 500 meters (1,640 ft) away.  Read More

Microbial fuel cells turn urine into a constant flow of electrical power

Human urine has been turned into all sorts of things over the centuries. Alchemists distilled phosphorous from it, it was once used for the production of gunpowder, tanners employed it in great vats to tan hides, and it has served as the basis of a myriad chemical substances, including the first types of plastics. Now yet another use for this ubiquitous liquid has been created. Researchers working at the University of the West of England (UWE Bristol) have built a urinal that converts urine directly into electricity.  Read More

A new high-efficiency biogas plant developed at the Fraunhofer Institute in Germany could ...

Researchers at the Fraunhofer Institute have developed a "biobattery" in the form of a highly efficient biogas plant that can turn raw materials like straw, scrap wood and sludge into a variety of useful energy sources including electricity, purified gas and engine oil. The new plant design, currently being put to the test in a prototype plant in Germany, is said to be highly modular and economically viable even at the small scale.  Read More

Tesla home battery, which is currently produced for SolarCity's home energy storage system...

The same lithium-ion battery technology that powers Tesla’s electric vehicles will be used to develop a battery for the home, according to a statement by CEO Elon Musk during a recent conference call with analysts. The batteries would be used by homes and businesses to store excess energy generated from solar panels during the day, and drawn from at night when panels sit idle.  Read More

The energy-harvesting tree collects energy from light, temperature differences, and vibrat...

In January, the VTT Technical Centre of Finland unveiled its decorative, mass-producible organic photovoltaic (OPV) leaves designed to capture energy from interior lighting to power small devices and sensors. Now, the company has followed the logical path and come up with an energy-harvesting tree that generates electricity from a variety of sources.  Read More
