Chava Energy The Market for Concentrated Solar Power is Hot and Getting Hotter BOSTON--(BUSINESS WIRE)--Despite competitive photovoltaic prices and lingering environmental and financing concerns, concentrating solar power (CSP) technologies are poised for gigawatt-scale adoption in 2011; and future growth will remain healthy as the generation stack increasingly incorporates CSP plants in excess of 100 MW. However, in order to land their share of this emerging market, utilities and developers alike will need a clear grasp of the economic and performance factors driving adoption of CSP’s four main technology contenders, according to a new report from Lux Research. “Though trough technologies have been dominant to date, we expect power tower solutions to gain increasing prominence as the technology is proven, because their integration with thermal storage technologies smashes through the fundamental constraint that has held solar back to date: intermittency.” Among the report’s key findings: Dish Stirling offers the lowest capital expenditures.

Torresol Energy - Gemasolar thermosolar plant Gemasolar is the first commercial-scale plant in the world to apply central tower receiver and molten salt heat storage technology. The relevance of this plant lies in its technological uniqueness, since it opens up the way for new thermosolar electrical generation technology. Characteristics of Gemasolar: Rated electrical power: 19.9 MWNet electrical production expected: 110 GWh/year Solar field: 2,650 heliostats on 185 hectaresHeat storage system: the molten salt storage tank permits independent electrical generation for up to 15 hours without any solar feed. The prolongation of the plant's operating time in the absence of solar radiation and the improvement in efficiency of the use of the heat from the sun makes Gemasolar's output much higher than that which is delivered by other technologies in a facility with the same power. The notable increase in the plant's power efficiency guarantees electrical production for 6,500 hours a year, 1.5 to 3 times more than other renewable energies.
Algenol Biofuels - Harnessing the Sun to Fuel the World BuildItSolar: Solar energy projects for Do It Yourselfers to save money and reduce pollution Main Page Are Solar Thermal Power Plants Doomed? Solar thermal power plants--which produce power from the heat of the sun--remain one of our favorite renewable energy technologies, but it might be in serious trouble. And this time the culprit is not cheap natural gas, the Koch Brothers, or the desert tortoise advocates. This time, the adversary is the other half of the solar family. Photovoltaic panels have plummeted in price over the last few years while companies such as First Solar and SunPower have devised strategies for building large-scale power plants with technology that in the past might have ended up on roofs or in small, ground-mounted projects. The solar thermal, or concentrating solar power (CSP) industry began to flourish in the late 1980s and early '90s in California with the construction of 354 megawatts of parabolic trough plants in the Mojave Desert. Then, the state allowed a real estate tax exemption to lapse, a change in the law that companies like Solel and Luz warned would kill them off. A bleak outlook? Conclusion
Filastruder: A robust, inexpensive filament extruder. by Tim Elmore We've successfully shipped our Kickstarter kits, and we're ready to take orders through our website - ****************************WAITLIST OPEN:Many of you have asked for more kits. We are pretty much at capacity, with orders into September, but have opened a waitlist to notify you as soon as we're ready to ship again. Send an email to firstname.lastname@example.org to reserve your spot. Are you frustrated with the high cost of filament for your 3D printer? The Filastruder meets these needs and more, because it is a filament-making machine. Others have tried to produce filament extruders, but have run into difficulties. and run for hundreds of hours, producing dozens of spools of quality filament. The design has been iterated and refined based on beta testers' feedback, and is now ready for prime time. History:In the fall of 2012, I purchased a Solidoodle 2 Pro, and began experimenting with 3D printing.

If the technology was so good, we thought, how come they didn't have any customers yet? We forgot about the invitation and the company until several months later, when our friend called again.
Insolation US annual average solar energy received by a latitude tilt photovoltaic cell (modeled) Absorption and reflection The object or surface that solar radiation strikes may be a planet, a terrestrial object inside the atmosphere of a planet, or an object exposed to solar rays outside of an atmosphere, such as spacecraft. Some of the radiation will be absorbed and the remainder reflected. Usually the absorbed solar radiation is converted to thermal energy, causing an increase in the object's temperature. Projection effect The insolation into a surface is largest when the surface directly faces the Sun. Figure 2 One sunbeam one mile wide shines on the ground at a 90° angle, and another at a 30° angle. In this illustration, the angle shown is between the ground and the sunbeam rather than between the vertical direction and the sunbeam; hence the sine rather than the cosine is appropriate.

Les avantages et limites des mobiles "écologiques" - Le blog Hi-Tech de Chonch Les chargeurs On va parler d'abord, des chargeurs économiques. Dans le but d'économiser de l'énergie, ces chargeurs sont, moins gourmands, en électricité. Les emballages Les emballages sont, eux aussi, plus écologiques, car ils sont fabriqués, en papier, ou en carton recyclé, et sont minimisés. Le solaire La plus grande avancée, en terme de téléphone écologique, est, sans doute, l'utilisation de capteurs solaires, appliqués sur le dos du téléphone. Les logiciels Les téléphones écologiques sont aussi équipés de logiciels capables de calculer les émissions de CO2 (dioxyde de carbone) économisées, grâce aux capteurs solaires (LG Pop GD-510), ou grâce à la marche à pied, plutôt que l'utilisation de la voiture (samsung Blue Earth). Le recyclage Des portables recyclables sont aussi imaginés, pour l'instant, à l'état de concept, notamment, le GreenHearth de Sony Ericsson. Les limites Pour l'instant, ces avancées écologiques sont encore limitées, à cause des composants internes du téléphone. En bref
Superconducting magnetic energy storage - Wikipedia, the free en Superconducting Magnetic Energy Storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil which has been cryogenically cooled to a temperature below its superconducting critical temperature. A typical SMES system includes three parts: superconducting coil, power conditioning system and cryogenically cooled refrigerator. Once the superconducting coil is charged, the current will not decay and the magnetic energy can be stored indefinitely. Due to the energy requirements of refrigeration and the high cost of superconducting wire, SMES is currently used for short duration energy storage. Therefore, SMES is most commonly devoted to improving power quality. If SMES were to be used for utilities it would be a diurnal storage device, charged from baseload power at night and meeting peak loads during the day.
