Tesla unveils battery storage system for home, business and utility use

By - May 1, 2015 5 Pictures
The Tesla home battery system hinted at by CEO Elon Musk several months ago has finally been unveiled by Musk himself at the company’s design studio in Hawthorne, California. Dubbed the Powerwall, the stationary home battery offers 10 kWh of storage capacity for the relatively modest price of US$3,500. A smaller unit is also available at 7 kWh for $3,000, and homeowners can stack multiple units if needed. Read More

New heat-recovery system makes Stanford one of world’s most energy-efficient uni's

By - April 26, 2015 7 Pictures
At Stanford University in California, it’s normally the Nobel-winning researchers who make the news. But with the commissioning of a novel renewable energy system, the campus’s humble heating and cooling system has grabbed some headlines. Using a first-of-its-kind heat recovery system, and drawing a substantial percentage of its electricity from solar, the university is greening up its operations in a move that will see greenhouse gas emissions cut by 68 percent and fossil fuel use cut by 65 percent.

Audi just created diesel fuel from air and water

By - April 26, 2015 7 Pictures
Audi is looking to fuel the future without fossil fuels. One of the company's pilot plants in Germany has just produced the first batches of a synthetic diesel made using only water and air. The company's pilot plant, which is operated by German startup Sunfire, produced its first batches of the "e-diesel" this month. German Federal Minister of Education and Research Johanna Wanka put a few liters of the fuel in her work car, an Audi A8, to commemorate the accomplishment. Read More

New device combines the advantages of batteries and supercapacitors

By - April 19, 2015 2 Pictures
Scientists at UCLA's California NanoSystems Institute have developed a new device that combines the high energy densities of batteries and the quick charge and discharge rates of supercapacitors. The hybrid supercapacitor is reportedly six times as energy-dense as a commercially available supercapacitor and packs nearly as much energy per unit volume as a lead-acid battery. Read More

GOCE gravity satellite data helps produce tool for geothermal energy development

By - April 17, 2015 2 Pictures
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

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.
