Research unveils extensive U.S. geothermal resources

By - October 27, 2011 6 Pictures
As a green energy source, geothermal heat is tough to beat, but until recently, it was believed to be economically feasible only in areas with shallow tectonic (volcanic) activity. Now, with a generous grant from Google.org, the search engine giant's philanthropic arm, two scientists from Southern Methodist University (SMU) have pooled together the results from more than 35,000 data sites to paint a very different, almost rosy, energy picture for the United States and, indeed, the world.

Nanotech to boost solid state hydrogen storage

By - March 9, 2011
Hydrogen has great potential as a clean fuel source for powering our cars and airplanes, but it also poses some big hurdles – in particular, how to store it. Making practical use of hydrogen in gas or liquid form raises difficulties in terms of volume and pressurization – a hydrogen gas tank for a car would need to be around four times larger than current petroleum tanks. Another possible solution is the use of solid state hydrogen and the European Aeronautic Defense and Space Company (EADS), along with the University of Glasgow, hope to boost this approach by developing a new storage system using materials modified at the nanoscale that receive and release the hydrogen at a faster rate.

New study says world can be completely powered by clean energy in 20-40 years

By - January 27, 2011
Here at Gizmag we cover a seemingly endless stream of renewable energy technologies designed to wean us off our reliance on fossil fuels and improve the health of the planet. As important as such developments are, for these technologies to have an impact they must of course be implemented – and on a large scale. What has been sorely lacking is a plan to accomplish such a Herculean feat. Now researchers from the University of California-Davis and Stanford University have published a study that details one scenario to completely convert the world to clean, renewable energy sources – and they say it could be done in 20 to 40 years using technology available today at costs comparable to fossil fuel-based energy.

Windstalk concept is a wind farm without the turbines

By - October 13, 2010 7 Pictures
Wind turbines are an increasingly popular way to generate clean energy with large-scale wind farms springing up all over the world. However, many residents near proposed wind farm sites have raised concerns over the aesthetics and the low frequency vibrations they claim are generated by wind turbines. An interesting Windstalk concept devised by New York design firm Atelier DNA could overcome both these problems while still allowing a comparable amount of electricity to be generated by the wind.

Going where the four winds blow with the mobile wind turbine concept

By - October 6, 2010 9 Pictures
Despite numerous refinements and improvements to the technology used to harness the power of the wind, windmills of old share an obvious characteristic with their gigantic modern counterparts. They're static. A network of designers coming together under the banner of Pope Designs has come up with a mobile wind turbine concept that could just change all that. Able to generate and store enough power to meet its own needs, the turbine could also be erected anywhere the wind blows to provide a source of clean energy to those who need it. Read More

New research shows real government subsidies for clean and dirty power

By - August 1, 2010
How can you tell when a politician is lying? First check to see if his/her lips are moving. New research has revealed that despite what they would have you believe, the world’s governments subsidize the fossil fuel sector far more than they do renewables and biofuels. Indeed, the assistance delivered to the oil, coal, and other fossil fuel sectors makes a mockery of claims that government is serious about reducing carbon emissions. Hey folks, that’s YOUR MONEY!

Frog Design and ECOtality team up for smart EV charging solution

By - July 29, 2010 5 Pictures
Well, it was only a matter of time. Electric vehicle charging stations aren’t even commonplace yet, but already someone has come up with a better-looking one. Frog Design, well-known for developing cool concepts such as an Intel Point-of-Sale kiosk and a range of wearable devices, has teamed up with clean energy company ECOtality to create the Blink EV charging station. There are two versions, one for homes and one for commercial use, and they’re both pretty snazzy. Read More

World's largest laser takes first steps towards nuclear fusion reaction

The quest to create a controlled fusion reaction is underway at the Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), with scientists reporting early progress ahead of ignition experiments which are due to start later this year. The ultimate aim of the world's largest laser - which is the size of three football fields - is to develop carbon-free, limitless fusion energy. Read More

ONR’s microbial fuel cell generates electricity from mud

By - April 20, 2010
It is estimated there are approximately five nonillion (that’s 5x10 to the power of 30) bacteria on Earth, and although they generally get a bad rap, there are actually many beneficial bacteria that are vital to life on our planet. As we’ve seen previously, scientists are now looking to harness bacteria to produce electricity through microbial fuel cells. These microbial fuel cells (MFCs) convert chemical energy to electrical energy to offer a clean, efficient and reliable alternative to batteries and other environmentally harmful fuels. Recognizing their potential the Office of Naval Research (ONR) has developed an MFC that could revolutionize naval energy use by converting decomposed marine organisms into electricity. Read More
