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.
Is rooftop solar right for you? And what if it’s not? | EcoVision Sustainable Learning Center - Educating a Greener World If you’re thinking about installing solar panels on your building’s rooftop allowing you to generate your own clean and renewable electricity from the sun, you’re not alone. Solar is growing in popularity at an incredible rate. According to the Solar Energy Industries Association (SEIA), a new solar project is being installed somewhere in the U.S. every four minutes! But there are lots of things to take into consideration before moving forward with a rooftop solar installation. So, how do you know if your roof is ready for solar? Starting Out You will need to have a professional solar installer and structural engineer to perform onsite inspections of your property to determine if it is suitable for a solar photovoltaic system. Adequate Roof Space The average size of a residential solar PV system is about 5,000 watts. Correct Rooftop Orientation For optimal performance of a PV system, a south-facing roof is the most desirable. Structural Considerations Building Codes Neighborhood Ordinances
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
The perovskite lightbulb moment for solar power | Technology | The Observer The worst part of my job as a materials scientist is going to conferences. They are often turgid affairs conducted in the ballrooms of hotels so identical to one another that you can't tell whether you are in Singapore or Manchester. The same speakers are there, for the most part droning on about the same thing they droned on about at the last conference. I should know, I am one of them. But occasionally, just occasionally, someone says something so radically new that it causes you sit up and actually listen. This was the scene at the Materials Research Society conference in Boston last December, where a breakthrough in perovskite solar cells was announced. If we could capture approximately 1% of the sunlight falling on to the British Isles and turn it into electricity we would meet our current energy demands. Silicon is a poor conductor of electricity because all of its four outer electrons are bound up in the chemical bonds holding the crystal together.

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.

The Rodin Coil: Is It The Greatest Discovery of All Time? Free energy is easily one of the hottest topics in the world within alternative news. While mainstream news continues to ignore the growing interest around the subject, alternative news outlets are providing new information about the inventions, science, mathematics and suppression of free energy technologies. We even covered the subject in our new documentary The Collective Evolution III: The Shift The trouble with the advancement of free energy as it stands now lies in a couple clear areas. 1. However, these hang ups are not stopping the spread of information surrounding not only the science but also the reality of these devices. “They say mathematics is the language of god, but until now nobody has been speaking god’s language”. As stated by Marko Rodin and his volunteers, the Rodin Coil has the ability to completely transform our world given what it is capable of. Practical Implications Of This Technology More Free Energy Research Sources:
Paper-thin printed solar cells could provide power for 1.3 billion people The cost of solar power has declined dramatically over the past few decades, from $40 per watt in 1977 to $0.74 per watt in 2013. This trend is expected to accelerate as improvements in efficiency and new technologies come online. This is good news for citizens of developed countries who want to make the switch to a cleaner and increasingly cheaper energy source. The shift to solar may be most dramatic for those living in developing countries. Thanks to inexpensive printed solar cells, 1.3 billion people currently without electricity may be able to plug in for the first time. Paper-thin solar cells require only an industrial printer to manufacture and are inexpensive to produce.

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
Moss used as "biological solar panels" to power a radio Swiss designer Fabienne Felder has worked with University of Cambridge scientists Paolo Bombelli and Ross Dennis to develop a way of using plants as "biological solar panels". "Theoretically any photosynthesising plant could be used as a biological solar panel", said the team, which has developed what it calls Photo Microbial Fuel Cells (Photo-MFCs) to capture and harness the electrical power of plants. The team has prototyped the world's first moss-powered radio to illustrate the potential of its Photo-MFCs. Moss was chosen because its photosynthetic process makes the plants particularly efficient at generating electricity. Fabienne Felder developed the technology with biochemist Dr. The radio is the first time Photo-MFCs have been used to run an object demanding more power than an LCD screen. The moss grows on top of a composite of water-retaining materials, conductive materials, and biological matter. The team has high hopes for the potential of this emergent technology. Moss FM Dr.
