Electric cars to become mini power plants in California’s energy grid

By - March 29, 2015 4 Pictures
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.

Goodyear BHO3 concept tire generates electricity

By - March 17, 2015 11 Pictures
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.

Urinal prototype uses fuel cells to generate steady stream of electricity

By - March 7, 2015 2 Pictures
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

Modular biobattery plant turns a wide range of biomass into energy

By - March 1, 2015 1 Picture
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 gearing up for release of batteries for the home

By - February 25, 2015 1 Picture
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

VTT's energy-harvesting "tree" generates electricity from multiple sources

By - February 19, 2015 4 Pictures
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

Swaying this way saves energy while walking

Just two days after opening, The London Millennium Footbridge was closed to eliminate its sway. Turns out staying with the sway would have had its benefits, as researchers have found that it reduces the amount of energy expended when walking across the bridge. Read More
