Scientists at Stanford University have built the world's first all-carbon solar cell. Because carbon offers a combination of low cost and high performance, it is a viable alternative to current photovoltaic materials, which are expensive. This new solar cell is made from materials such as carbon nanotubes and "buckyballs".
A group of scientists have put the world on alert that a massive solar flare could happen within the next two years that could harm power grids, communications, and satellites around the world. The scientists say that the risk of a massive flare that could harm systems on the earth increase as the sun reaches the peak of its 10-year activity cycle. The scientists say "governments are taking it very seriously."
You only have to set foot in most Walmart stores to know that the company wants to be green. For instance, in my local store, there are hordes of skylights all around the building in the ceiling and lights in the store turn off and on depending on how much light is coming through those skylights from the outside. That means you to be walking around and suddenly some of the lights turn off making the interior darker. I assume most Walmart locations use similar systems.
An enormous sunspot observed on the sun over the weekend may portend problematic solar activity, according to a National Oceanic and Atmospheric Administration report. The cool area of the sun known as AR1476, which contains multiple sunspots big enough to see with even basic astronomy equipment, displayed complex beta-gamma magnetic fields as it passed within view of the Earth on May 6th.
Scientists at the University of Southern California have developed new solar cells in the form of a liquid that can be painted or printed onto clear surfaces. The new technology is cheap to produce and relies on stable solar nanocrystals that are only four nanometers in size, which is so small you could fit 250 billion on the head of a pin. These particles are then suspended in liquid like pigment and can be printed like ink.
Sun observers have released clips of a vast solar tornado, as wide across as five Earths, that broke the surface of the star back in September 2011. Caught on camera by NASA's Solar Dynamic Observatory and spotted in the footage by the Institute of Mathematics and Physics at the University of Aberystwyth in Wales, the "coronal mass ejections" spurt from solar prominences and the coronal cavities above them.
For those of you unfamiliar with the term "Venus Express," do not worry: it's not a train heading into outer space - it's already out there, and it's a spacecraft in crisis. There aren't any humans aboard this spacecraft at the moment, it being the eyes and ears of the European Space Agency around the second planet from the sun in our solar system, but concern remains as 40 hours have passed since the most recent solar storm has pushed over the unit and it's gone "blind." The cameras aboard this spacecraft have been rendered inoperable for the time being with officials racing to get them back online before they're lost for good, they meanwhile relying on gyroscopes to keep the unit online and on track.
SolarFocus has released the first solar-charged cover for the Kindle e-Reader. As if your Kindle didn't already have great battery life, they've gone ahead and integrated a 1500mAh battery into the case. There is also an LED light that pops out once a button is pressed on the cover.
E-Ink's power-sipping frugality makes it an ideal partner to solar panels, and so it's hard to believe SolarFocus' SolarKindle idea hasn't been offered before. A combination case, recharging system and LED light for the Kindle ereader, the new accessory is fronted by a bank of solar cells that recharge an integrated 1,500 mAh battery pack. That battery can be used to top up your Kindle's power, turn on the flip-out LED lamp, or both.
When it comes to reducing the power that large data centers consume a seemingly small reduction can have huge savings in power consumption and the cost of operating the data center. Apple is getting ready to install a large solar panel farm on land it already owns in Maiden, North Carolina. Apple has been issued permits needed in Catawba County to reshape the 171 acres of land it owns adjacent to the data center.
