Lists Flywheel Energy Storage Solar Energy Articles (Solar Today) Provides abstracts of articles from Solar Today. 2-01 News -04-18-08 Ausra Solar Thermal Energy (Time.com) "There are two ways to get electricity from the sun. The first is the one you know: photovoltaic panels transform the light of the sun directly into electricity. The second is to harness the sun's heat. Solar thermal technology — also known as concentrated solar power — uses vast fields of mirrors to focus the heat of the sun to drive an electric turbine. Solar thermal may be low-tech, but in empty desert areas like much of the American southwest, it offers the potential to be a utility-scale replacement for fossil fuels." 04-08 -04-18-08 Enphase Micro-Inverters (Time.com) "Normally, solar installations contain a number of solar panels, but the entire installation shares one inverter, which converts the electricity generated by all the panels for use in our homes and businesses. If there's a fault in one panel, the entire system can slow down — just like a chain of Christmas lights goes out if one bulb malfunctions. Enphase puts micro-inverters on each individual panel in an installation, which boosts overall productivity. Even better, Enphase's micro-inverters communicate via the Internet, allowing the company to track the performance of every solar panel during every minute of every day." 04-08 -04-18-08 First Solar (Time.com) "Clean-tech companies are always betting on the future. But First Solar is the rare green company that is making a killing right now. The Phoenix-based thin-film solar panel manufacturer, launched with money from Wal-Mart's Walton family, began commercial production of its inexpensive solar modules back in 2002, ahead of most competitors — since then, First Solar has gone from strength to strength. It already dominates the emerging thin-film solar industry, and in 2006 the company went public in one of the strongest IPOs yet in the clean-tech sector." 04-08 -04-18-08 Nanosolar (Time.com) "The CEO of the thin-film solar cell manufacturer Nanosolar, Roscheisen says that he can sell solar panels at $1 per watt of electricity produced — a price that is competitive with coal, and far lower than what his competitors can do. The secret is that Roscheisen's company uses nanotechnology to cut the cost of manufacturing, producing roll after roll of thin-film solar panels in a process that looks like a printing press." 04-08 -06-20-05 Group to Launch Solar Sail Orbiter (ABC News) "The world's first solar sail spacecraft takes flight on Tuesday, launched by space enthusiasts who cobbled the privately funded mission together on $4 million and an untested theory that light can power limitless space exploration." 6-05 09-05-04 Solar Car to Go On Tour (MSNBC News) "Nuna 2, the world's fastest solar-powered car with a top speed of 105 mph, started a nine-day drive through the two countries Sunday to promote solar energy and space technology." 9-04 Solar Energy News (Solar Energy Industries Association) Provides news on solar energy initiatives and successes. 10-00 Papers Bicycles (Awesome Library) Summarizes strengths and weaknesses of bicycles and makes some recommendations. 6-01 Green Cities (MotherJones.com) Describes efforts cities are making to use less polluting sources of energy. 9-01 Highly Efficient Solar Cells Developed (ScienceDaily.com) "Photovoltaic panels have a new design: concentric circles that focus the sun's rays on miniaturized modules. Having the panels automatically sense sunlight and turn towards it also makes these high-tech solar cells more efficient." "Conventional solar systems are about 14 percent efficient. This system has a combined heat and power efficiency of nearly 80 percent. 'What they're doing is very efficiently capturing and transferring that light into electricity and the solar heat into hot water,' Dyson explains." 06-08 Infrared Photovoltaic Cells (J X Crystals) Describes a new cell, thermophotovoltaic (TPV), that converts infrared light into electricity. It can be used in a furnace, for example, to convert wasted infrared heat into additional electricity. 6-01 Model Solar Car Challenge (ModelSolarCar.org) Describes a challenge for young students to design a sloar powered model car. 8-01 Renewal Energy (Arizona Solar Center) Provides an overview of sources of renewable energy. 1-99 Solar Heater - Invention and Design (Cross Talk) Provides a case study in the invention and marketing of a product. Solar Maps of the USA (Bergey.com) Provides solar maps of the USA. 6-01 Solar Power - A Short History (MotherJones.com) Provides an essay that describes efforts in the 1970's to move toward solar power. Argues that political forces have since forced it into a slow pace of growth compared to its potential. 9-01 Solar Power - Cost Effectiveness (Community Office for Resource Efficiency - Udall) "If you value the future or the environment, PV [solar electric power] is cost effective. If you don't, it isn't. It's that simple." 5-01 Solar in Tennessee (MSNBC News) "TVA offered to pay 15 cents for every kilowatt hour of homegrown power they produce — slightly more than double the 6 to 7 cents a kilowatt hour homeowners pay for power from their TVA distributor. TVA also threw in a $500 bonus." 9-05 The "Green Energy Gold Rush" (Time.com) "Global investors plowed $148 billion into new wind, solar and other alternative energy assets last year, in what the United Nations describes as a 'green energy gold rush' gaining speed the last several years." 07-08 Vital Signs of Improvement in the Environment (WorldWatch.org) "Fossil fuel consumption is growing, but—good news—so is solar and wind power. Read more below and then learn what you can do." Includes articles on what you can do to reduce problems for the environment. Topics include Fossil Fuels, Carbon Emissions, Oil Spills, Urban Sprawl, Automobile Production, Bicycle Production, Car Sharing, Wind Power, Solar Power, Appliance Efficiency, and Compact Fluorescent Lamps, 4-03 Projects Build a Solar Car (University of Minnesota Solar Vehicle Project) Provides choices for building a solar vehicle online. Allows you to see the effects of your choices in a virtual race. 6-01 Lease Solar Energy Without Extra Costs (Renu.Citizenre.com) "Plainly put, the Citizenre- Corporation pays for, installs, owns and operates the solar installation. You don’t have to worry about maintaining the equipment or any of the other concerns that come with making an investment into solar power. All you are required to do is pay for the electricity generated from these panels, at a fixed rate that is at or below your current electricity price, for up to twenty-five years."
