One freezing day in February 2006, physicist Andreas Mershin huddled with others around a tree on the Massachusetts Institute of Technology campus to watch an unlikely demonstration. An engineering company claimed it could produce electricity simply by wiring a nail in the tree’s trunk to a metal rod in the ground. Sure enough, the demo [...]
Nesjavellir Geothermal Power Station: Iceland’s second largest geothermal power station
A proposed high voltage electrical cable running across the floor of the North Atlantic Ocean to tap Iceland’s surplus volcanic geothermal energy would become the world’s longest underwater electrical cable, if it goes ahead. The cable would be a significant step towards a pan-European [...]
As part of its Battery 500 project — an initiative started by IBM in 2009 to produce a battery capable of powering a car for 500 miles — Big Blue has successfully demonstrated a light-weight, ultra-high-density, lithium-air battery.
In IBM’s lithium-air battery, oxygen is reacted with lithium to create lithium peroxide and electrical energy [...]
Harnessing the energy of sunlight can be as simple as tuning the optical and electronic properties of metal oxides at the atomic level by making an artificial crystal or super-lattice ‘sandwich,’ says a Binghamton University researcher in a new study published in the journal Physical Review B.
“Metal oxides are cheap, abundant and ‘green,’” said Louis [...]

A cool new concept being tested in the Abu Dhabi desert uses a wind turbine to condense water from the air and pump it into storage tanks for filtration and purification. The technology was created by Eole Water after its founder, Marc Parent, was inspired by the water he could [...]
Just 14 months ago, the Indian state of Gujarat announced that it was building a $2.3-billion solar park — the largest photovoltaic power station the world has seen so far.
Narendra Modi, Chief Minister of Gujarat, revealed this Thursday via Twitter that the solar park had been switched on:
“Gujarat dedicates 600 [...]
On April 20, 2010, a reckless attitude towards the safety of the Gulf Coast by BP, as well as Transocean and Halliburton, caused a well to blow out 5,000 feet below the surface of the Gulf of Mexico. As the world watched in horror, underwater cameras showed a seemingly endless flow of oil [...]
When populations expand, the demand for fresh water rises. And over the past two decades, population growth has contributed to a 6 percent decline in worldwide surface water, according to a new study.
Human population growth has contributed to a 6 percent global drop in surface water sources such as lakes, rivers and [...]
Scientists say the notoriously dry continent of Africa is sitting on a vast reservoir of groundwater.
They argue that the total volume of water in aquifers underground is 100 times the amount found on the surface.
The team have produced the most detailed map yet of the scale and potential of this [...]
