Australia's vast geothermal energy resources represent thousands of years worth of untapped power

By - July 5, 2015 3 Pictures

Australia is sitting on top of some of the world's most potent geothermal energy sources, according to government estimates. Just one percent of the hot rock energy less than 5 km under the surface would be enough to meet the whole country's entire power needs for 26,000 years if it was tapped. So why aren't we seeing more movement on it?

Could a hydrogen-powered iPhone be in the works?

For decades we've been promised that hydrogen fuel cells will revolutionize our lives, but it always seems to be around the next corner. But that hasn't stopped one UK company from pursuing a near future in which iPhones and other devices are completely disconnected from the electrical grid and instead use embedded fuel cells to power themselves for a full week between recharges.

Moth eyes inspire more efficient photoelectrochemical cells

By - July 17, 2014 3 Pictures
As nocturnal creatures, moths need to maximize how well they can see in the dark whilst remaining less visible to avoid predators. This ability to collect as much of the available light as possible and at the same time reflect as little as possible, has inspired Researchers at the Swiss Federal Laboratories for Materials Science and Technology (Empa) to design a new type of photoelectrochemical cell using relatively low cost materials.

Net-zero energy test home ends year-long study with surplus energy

By - July 10, 2014 8 Pictures
Braving a harsh winter with snow-covered solar panels, the Net-Zero Energy Residential Test Facility (NZERTF) in Washington DC has come up trumps in a year-long study of its energy harvesting capabilities. Located on campus at the National Institute of Standards and Technology (NIST), researchers used computer simulation to replicate the energy consumption of a family of four. At the end of its first 12 months, there was a large enough surplus to power an electric car for 1,440 miles (2,317 km). Read More

Seatower's game-changing wind turbine foundations could reduce the cost of offshore wind farming

By - May 13, 2014 14 Pictures
Offshore wind farming combines the clean, green, environmentally neutral benefits of land-based wind turbines, while being a lot less visually intrusive ... and restricting the usual NIMBY opposition to crustaceans and invertebrates. It's currently a lot more expensive to install turbines out at sea, though, and that's restricting the sector's development. Which is why the Seatower Cranefree turbine platform could be such a significant step forward. Cheaper and easier to install, and requiring less gargantuan and specialized equipment than standard monopile foundations, the Seatower base could help offshore wind farms reach profitability a lot quicker.

Energy-producing Honda Smart Home gives more than it takes

By - April 1, 2014 13 Pictures
With homes and light-vehicles accounting for roughly 44 percent of total greenhouse gases emitted in the US, neutralizing these emissions would certainly go a long way towards a clean energy future. What if these sources of pollution could not only be nullified, but play an active role in reducing our environmental footprint? Such is the thinking behind the Honda Smart Home US unveiled last week, which generates enough solar energy to power both car and home, with a little left over to feed back into the grid. Read More

Scientists announce breakthrough in quest for fusion power

By - February 13, 2014 2 Pictures
In a perfect example of beating swords into plowshares, a team of scientists at the Lawrence Livermore National Laboratory's (LLNL) National Ignition Facility (NIF) in California reached a milestone in the quest for practical fusion power using a process designed for the development and testing of nuclear weapons. The announcement in the February 12 issue of Nature claims that the team used the world’s most powerful laser barrage to produce a controlled fusion reaction where more energy was extracted from the fuel than was put into it.

Plug&Sun CPV system powers up remote Madagascan village

By - October 22, 2013 2 Pictures
Fondation Énergies pour le Monde (Energy for the World Foundation), an organization that promotes clean energy in developing countries, has completed the installation of a concentrator photovoltaic (CPV) system in Ambondro, southern Madagascar. The CPV system was also combined with existing wind turbines in the village, with project partner Sunidarity claiming it is the first decentralized rural electrification operation of its kind in Madagascar.
