Wireless Power Transmission Made Better by Old Electronics Principles and New Circuitry
Posted in Electric Vehicles, Nikola Tesla on May 16, 2012
NC State University researchers have recently implemented what is being used in radios for decades in wireless power transfer (WPT) receivers – the ability of the receiver to keep track of the transmitter’s frequency if the differences are really small. This could ultimately impact electric vehicle wireless power transfer systems by making them more efficient [...]

NASA Scientist Warns About Canadian Tar Sands’ Potentially Catastrophic Impact on Climate
Posted in Global Warming on May 14, 2012
Tar sands – Canada’s dream of a richer life, are about to disrupt changes so dramatic in the global climate that 20 to 50 percent of the planet’s species could go extinct and civilization as we know it could reach the edge of peril. However, those tar sands filled with bituminous fuel aren’t seeing daylight [...]

Researchers Urging Decision Makers for Agreement on Plutonium Waste Disposal
Posted in Nuclear Power on May 10, 2012
A new research on the actions to be done about nuclear waste has been recently published in the science journal Nature. Their conclusions have been that the wastes should be disposed of safely and securely, so that they are unreachable by third parties who could build nuclear weapons. Worldwide, about 500 metric tons of plutonium [...]

Gas Resulting from Geothermal Drilling Causes Respiratory Diseases in Iceland
Posted in Geothermal Power, Pollution on May 10, 2012
A three-year study performed in Iceland revealed that toxic gases associated with geothermal drilling can be dangerous to human health. The study found a link between underground-originating hydrogen sulfide (the rotten eggs-smelling substance) and asthma and various respiratory diseases. The hydrogen sulfide had been measured next to a busy intersection in Reykjavik, from March 2006 [...]

Microsoft to Become Carbon Neutral by Internally Taxing Carbon Emitted by Own Offices
Posted in Green Economics on May 9, 2012
Microsoft is going green starting July – the latest news tell that’s for sure. However they’re not taking the Facebook or Apple approach to that, but a rather more bureaucratic, systematized and nevertheless still effective way – they’re putting an internal tax on carbon emissions to each of their U.S. offices. Well, that may sound [...]

Scientists Theorize One of the Problems Facing Nuclear Fusion
Posted in Nuclear Power on May 7, 2012
Fusion reactors are thought to be the mothers of all power plants. They’ll emit no gases, eat up no polluting resources and provide all of the energy humanity needs for heading towards self-destr… evolution. However, science didn’t allow us thus far to produce more energy than we consume in a nuclear fusion process, but a new [...]

GELI to Unveil Operating System That Will Manage Future Smart Grids
Posted in Energy Storage on May 7, 2012
In the years to come, the electric grid is to change radically. What is now produced by coal-fired plants and consumed instantly, will then be produced by wind turbines and solar panels, and stored inside batteries or other forms of energy storage. The worldwide network of energy grids will be interconnected and will need software [...]
