The Solar Sunflower: Harnessing the power of 5,000 suns Sebastian Anthony Behold, the Solar Sunflower! Here they are trying a bunch of different reflector materials, which is why the segments all look slightly different. Sebastian Anthony Behold, the Solar Sunflower! High on a hill was a lonely sunflower. The Solar Sunflower, a Swiss invention developed by Airlight Energy, Dsolar (a subsidiary of Airlight), and IBM Research in Zurich, uses something called HCPVT to generate electricity and hot water from solar power. The two constituent technologies of the Solar Sunflower—concentrated solar thermal power and photovoltaic solar power—are both very well known and understood at this point, and not at all exciting. The reflectors are simply slightly curved, mirrored panels. The collectors are where most of the magic occurs. Photovoltaic cells, like most semiconductors, become less efficient as they get hotter. How then do you stop your collectors turning into very expensive puddles of molten metal? Cooling with hot water? Airlight Energy
Wilson Solar Grill for outdoor cooking - National Green Living A group of MIT students have been working on a solar grill that uses a Fresnel lens and solar energy to melt down a container of Lithium Nitrate, which is like a battery storing thermal energy for 25 hours. The heat created at temperatures above 450 degrees Fahrenheit is used for convection cooking outdoors. The MIT students are Derek Allen Ham, Eric Uva, and Theodora Vardouli. The project is part of their Innovation Teams, or iTeams, multi-disciplinary course taught by Fiona Murray at Sloan School in May 2011. The study is to do an entrepreneurial survey of product interest and business model plan for solar grill manufacture and distribution, both in third world countries like Nigeria and the U.S. where it might be an easier sell. There should be no more concern about the danger from the lithium battery since it is a sealed system and device would have to be severely dismantled for the chemicals to become an issue.
EWAO Nigerian Man Turns A VW Beetle Into A Solar And Wind Powered Car This is one of the coolest ideas and to top it off it’s completely reasonable too! Segun Oyeyiola was a student at Obagemi Awolowo University and while he was in attendance there, he converted his gas thirsty Volkswagen into a completely green energy machine by installing a large solar panel on the top of the car, with an additional wind turbine underneath the hood. His idea is to have his concept of his new invention to become “Nigeria’s future car.” At birth, the battery took 4-5 hours to charge, that was definitely not ideal. Yet the largest challenge, according to Mr. Check out this animation of a solar/wind-powered vehicle, illustrating how the batteries are charged via the multiple turbines. The roof houses a mounted solar honeycomb-membrane panel which absorbs and collects the rays of the sun when parked and while it’s on the go, transferring that energy to the main energy housing located in the back of the vehicle.

Basic view of the Can Stirling Engine #2 – Cutting the wood board appropriately You have to make two side boards, two boards to fix the can, and a bottom one. #3 – Manufacturing the wood piston After you fit the cut balsa pieces with glue, you can glue the fishing line to the center of the piston with SuperGlue. #4 – Cutting he diaphragm #7 – Building the frame
Self-Healing Solar Cells -- Vascular Channels Based On Plant Leaves Allow For Self-Healing In New Solar Cells Clean Power Published on August 15th, 2013 | by James Ayre Self-healing solar cells — possessing “vascular” networks similar to those in plant leaves — have now been created by researchers from North Carolina State University. North Carolina State University explains: In their new paper, the researchers show that creating solar cell devices with channels that mimic organic vascular systems can effectively reinvigorate solar cells whose performance deteriorates due to degradation by the sun’s ultraviolet rays. “The design of NC State’s regenerative solar cell mimics nature by use of microfluidic channels.”Image Credit: North Carolina State University “Organic material in DSSCs tends to degrade, so we looked to nature to solve the problem,” stated lead researcher Orlin Velev, who’s also the Invista Professor of Chemical and Biomolecular Engineering at NC State. The research was funded by the National Science Foundation and the US Department of Energy. About the Author
New Printable Solar Panels Are Ready To Hit The Market! Australian solar technicians with the Victorian Organic Solar Cell Consortium have announced that they will soon put a new printable solar cell technology on the market. Trueactivist.com Image: CSIRO Printable Solar Panels May Be Coming to a Device Near You Australian solar technicians with the Victorian Organic Solar Cell Consortium have announced that they will soon be prepared to put a new printable solar cell technology on the market. Fiona Scholes, one of CSIRO’s senior researchers said that this new technology can actually print solar cells directly onto plastic and other materials. There can also be a number of commercial and industrial uses for this technology as well. “We print them onto plastic in more or less the same way we print our plastic banknotes. Scholes also pointed out that the cells are somewhat transparent, which would allow them to be printed on windows to bring power into homes and buildings.

German Engineer 3D Prints World’s First Solar Powered Stirling Engine Each and every day, I am blown away in yet another way by all of the new innovations that have quickly been coming into existence within the 3D printing space. It seems as though just a couple years ago no one even knew what 3D printing was, and today we have everything from 3D printed houses to 3D printed cars, prosthetic hands, electronics, and more. It makes me wonder just how much further along we will be in the next five or ten years. Haeuser himself is known for designing and creating several unique 3D printable devices, such as the “RepRap Windturbine.” Haeuser has designed and created the world’s first known 3D printed solar powered Stirling engine, an engine that runs completely off of the sun’s heat. “At the moment, a lot of people try to build Stirling engines with a 3D printer,” Haeuser explains to 3DPrint.com. His engine is powered using the solar rays of the sun to provide the engine with enough heat to make it run. “At this moment it’s a small engine,” Haeuser tells us.
Design Concepts | V3SOLAR Power Tree™ – Design Concept While land constraints have not been a primary concern for solar deployment in the past, this is certain to change. According to the DOE, the world currently uses about 15,000 GW of power and by the year 2050 the world will require approximately 30,000 GW. To satisfy this demand over the next 40 years, it would require building more than 1GW power plant each and every day! The Spin Cell™ can also be mounted in an array of “Power Trees” (illustration to the left), further reducing space needed for deployment as well as opening up new market opportunities — think parking lots and street lighting. Another inherent benefit of a Power Tree™ is the ability to operate Spin Cells™ above potential flood lines. Spin Cell™ solar farms can be built to include monitoring for each Spin Cell™, linked directly to a control room to maximize energy output and the overall performance of the individual Spin Cell™ or farm of Spin Cells™.
Tata Steel to Turn Steel Sheets into Solar Cells Using Spray-on PV Coating | Earth & Industry A group of organisations including Tata Steel-led Corus and Swansea University (Wales, UK) are developing a new technology that would convert steel sheets into power generating solar cells. The technology involves coating steel sheets with photo-sensitive dyes. The technology has significant applications since it is highly efficient even in diffused sunlight. Therefore, countries at higher latitudes or those with limited solar energy resource can generate significant amounts of solar-powered electricity with going for large-scale power plants. If extended, the technology can find its way to the automobile industry where photo-sensitive dyes can be applied to cars to generate electricity to split water into hydrogen and oxygen for fuel cells. Tata recently invested in an American company, Sun Catalytix, which integrates low-cost catalyst with solar-powered fuel cells to generate power. Tata has been making significant investments in the renewable energy sector, both in India and abroad.
