World record solar cell with 44.7% efficiency

World record solar cell with 44.7% efficiency
The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin jointly announced today having achieved a new world record for the conversion of sunlight into electricity using a new solar cell structure with four solar subcells. Surpassing competition after only over three years of research, and entering the roadmap at world class level, a new record efficiency of 44.7% was measured at a concentration of 297 suns. This indicates that 44.7% of the solar spectrum's energy, from ultraviolet through to the infrared, is converted into electrical energy. This is a major step towards reducing further the costs of solar electricity and continues to pave the way to the 50% efficiency roadmap. Back in May 2013, the German-French team of Fraunhofer ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin had already announced a solar cell with 43.6% efficiency. Related:  elektriciteit

A Material That Could Make Solar Power “Dirt Cheap” A new type of solar cell, made from a material that is dramatically cheaper to obtain and use than silicon, could generate as much power as today’s commodity solar cells. Although the potential of the material is just starting to be understood, it has caught the attention of the world’s leading solar researchers, and several companies are already working to commercialize it. Researchers developing the technology say that it could lead to solar panels that cost just 10 to 20 cents per watt. Solar panels now typically cost about 75 cents a watt, and the U.S. Department of Energy says 50 cents per watt will allow solar power to compete with fossil fuel. In the past, solar researchers have been divided into two camps in their pursuit of cheaper solar power. The new material may make it possible to get the best of both worlds—solar cells that are highly efficient but also cheap to make. “Between 2009 and 2012 there was only one paper.

How to Survive in the African Savannah - Survival Guide Tips | Africa Freak Blog - Your Eyes On Africa Many people visit the African continent: while some enjoy holidays to Egypt others look to explore the wide-open plains of the Savannah. Holidays to the region can include fun filled safaris and wildlife spotting activities, but on no account should you explore the region on your own without a guide. There are over 3000 species in the African Savannah and negotiating the area, especially at night, can be fraught with dangers. Finding Water The first thing you should try to do is find water. There are a few ways you can locate water; you could follow animal tracks and see if they lead to a stream, head for the highest point and find the source of a stream or you could dig beneath the surface of a dried up river bed. By heading to the highest point you may also be able to find civilization, so this might be the best course of action. From this vantage point you may be able to see smoke or the outline of villages. In some areas, roots can also be a good water source. Bi! Food Sources?

How I built an electricity producing wind turbine Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. I found a great piece of property. The problem is, it's so remote that there is no electric service available. That's not really a problem. No electricity equals no light pollution. One thing I noticed right away about my property is that most of the time, the wind is blowing. Let me state up front that I probably won't be able to help you out much if you decide to build your own wind turbine. Since no one seems to be reading the FAQ, I will answer the No. 1 question I get many, many times a day right here up front. Update: Here is a video of the wind turbine in operation. Update: Here is a video of me assembling and setting up the wind turbine on my remote off-grid property. I started the process of designing my wind turbine by Googling for information on home-built wind turbines. .

IntroJackie Chan DJ Tony Rico Checks InGet Loose DJ Tony Rico – Drop That BeatDankSleepless Nights Supa Dupa Focus Funny Looking Tower Generates 600% More Electrical Energy Than Traditional Wind Turbines The Sheerwind wind turbine promises to produce 6 times the electrical power than traditional wind turbines. This funny looking wind tower acts like a funnel, directing the wind from any angle, down through a tube to a ground based turbine generator. The funneling of the wind through a narrow passage effectively creates a “jet effect” increasing the velocity of the wind, while lowering the pressure. This is called the Venturi Effect. As such it can capture and generate electricity at a much lower wind speed than current wind power technologies. The idea is so simple, so elegant, and promises to produce so much more energy at lower cost and more efficiently, that it might just be the answer to many problems with current wind turbine technology. This technology is not really new in the science of fluid dynamics, however this is a new way to generate electricity, and if successful, promises to grow the wind energy in a more eco-friendly way than ever thought possible. via: Sheerwind Comments

6 Glasses With Integrated Displays That You Can Buy Today | Gadget Lab Google isn't the only player in the HUD market. Photo: Google While Google’s augmented-reality glasses are receiving immense attention — and scrutiny — they’re certainly not the first pieces of eyewear to include an integrated display. A company called Vuzix released its first pair of augmented-reality glasses, the iWear VR920, in 2009. The glasses contain two LCD displays that mimic a 62-inch screen sitting nine feet away. The Vuzix glasses were perhaps the first low-cost integrated-display glasses on the market that didn’t outright suck. The same can be said for the Sony Glasstron personal video headset that was released in 1997. But none of these stumbles have stopped companies from dipping their toes into the dubious waters of integrated-display eyewear. So, while Google leaves us hanging with very little actual information about Project Glass, the following headsets are doing their best to entice us into a world of integrated-display eyewear.

How Much Can You Save With Solar Panels? Just Ask Google If you’re considering solar power but aren’t quite sure it’s worth the expense, Google wants to point you in the right direction. Tapping its trove of satellite imagery and the latest in artificial intelligence, the company is offering a new online service that will instantly estimate how much you’ll save with a roof full of solar panels. On Monday, the company unveiled Project Sunroof, a tool that calculates your home’s solar power potential using the same high-resolution aerial photos Google Earth uses to map the planet. After creating a 3-D model of your roof, the service estimates how much sun will hit those solar panels during the year and how much money the panels could save you over the next two decades. “People search Google all the time to learn about solar,” says Google’s Joel Conkling. Click to Open Overlay Gallery The service is now available for homes in the San Francisco Bay Area, central California, and the greater Boston area. How Google Parses Your Roof Go Back to Top.

Love'em Some Christmas---Joseph Center Students in Zambia I am a student at Texas Christian University studying Music with minors in Arts Administration and General Business. As I was listening to Christmas hymns while talking to my boyfriend, Peter Cline, who is currently doing mission work in Zambia, a simple idea came to me---wouldn't it be nice to send some Christmas gifts to the local kids? So Peter went to talk to the headmaster and learned the bigger needs of the students in the local school/orphanage called Joseph Center. We were told that the most basic school supplies are unavailable for the students. So the idea soon expanded and we thought it's a perfect opportunity to help those students out with the advantage of Peter being in Zambia, living with a local apostle, and me being in the US. We plan to raise a minimum of 975 dollars to purchase school supplies for the kids at Joseph Center. 975 dollars for us might not mean that much, but it means: 760 small ruled note pads PLUS 1200 mechanical pencils PLUS 1240 blue ballpoint pens PLUS

HOW TO CHART THE SUN’S MOTION IN RELATION TO YOUR HOMESTEAD Learn to track the sun before you design your home to determine the best orientation for it, as well as how to take advantage of the sun rays, because the position is also important for the passive cooling and heating of the house. Understanding the sun’s motion relative to a site is an important aspect of a good permaculture design, as various elements like plants, animals and solar devices depend on sun for their functionality. A good appreciation of the earth’s rotation about its axis, its revolution around the sun and the consequences of these motions on the sun’s position and availability at a given location on the earth’s surface, is essential for maximizing plant productivity, harnessing maximum energy, minimizing energy usage and maintaining a comfortable indoor environment for humans and animals alike. For a given site, if we can create a chart that shows the areas of year round shade and year round sunshine, one can plan and design the various elements for optimal functioning.
