Solar Power goes to Extremes for 5cents per kwh : CleanTechnica - 0 views

  •  
    We already know that concentrated solar power (CSP) is shaking things up in the solar industry. A subset within the industry is turning up the heat. "Extreme" Concentrated solar magnifies intense sunlight onto a solar cell, at temperatures that could melt it, to boost efficiency for less money.

Dying to Boost Solar Efficiency by 50% : CleanTechnica - 0 views

  •  
    The most efficient form of solar technology today is (arguably) extreme concentrated photovoltaics, essentially solar panels placed under a magnifying glass, but the problem with these systems is heat. Concentrated sunlight can melt silicon solar panels unless you include specialized cooling systems. Cooling technology costs money, and the panels require expensive tracking mechanisms to follow the sun through the day. MIT's new solar system bypasses the heat and traching problems all together.

Peak Energy: Solar in the Sahara 'could power the whole of Europe' - 0 views

  •  
    The Times has a story in the "deserts of gold" genre, confusing solar PV (panels) with concentrating solar thermal power - Solar panels in the Sahara 'could power the whole of Europe'. There is a new twist to the story now though, with North Africa's wind power potential also being touted. All of Europe's energy needs could be supplied by building an array of solar panels in the Sahara, the climate change conference has been told. Technological advances combined with falling costs have made it realistic to consider North Africa as Europe's main source of imported energy. By harnessing the power of the Sun, possibly in tandem with wind farms along the North African coastline, Europe could easily meet its 2020 target of generating at least 20 per cent of its energy from renewable sources.

Solar Balloons Get $21 Million In Funding : MetaEfficient - 0 views

  • They look like foil party balloons, but they are actually very efficient solar concentrators. These solar “balloons” were developed by a company called Cool Earth, based in California, and it has just received $21 million dollars in investor funding. The company is now planning to build a 10-megawatt plant of solar balloons in the next couple years. This power plant would be comprised of 10,000 balloons, and cover roughly 80 acres!

Aluminium Giant to Make Solar CSP Cheaper - 0 views

  • This summer Alcoa will test a new way of making the solar troughs used to make concentrated solar power (CSP) that could reduce the cost by 20%.

Wave and Tidal Energy on the Rise: But Will it Work? | Renewable Energy News Article - 2 views

  •  
    Tidal & wave is the wild card for the energy sector. With 45 kW/m power in wave fronts, it's a sources of renewables that is already concentrated by nature. But after many decades, the sector remains stuck in concepts and trials. The La Rance facility by EDF is operating since the 70s - if it had been a dream technology, we'd have seen more of this by now.

Peak Energy: We're Off To See The Wizard - Storing Energy Using Ammonia - 0 views

  • The first of these is being put together by a South Australian company called Wizard Power, which is trying to commercialise research from the Australian National University (ANU) - a solar concentrator dish and a closed loop thermochemical energy storage system using ammonia.

Largest CPV Plant in Latin America to Feature New Skyline Solar X14 System | Free Green... - 2 views

  •  
    Skyline Solar today introduced the Skyline X14 System and announced that it has been selected for a 500-kilowatt (kW) concentrated photovoltaic (CPV) plant to be built in Durango, Mexico. DelSol Systems, one of Mexico's leading solar integrators, will construct the project, which will be the largest CPV plant in Latin America.

Flat Panel Technology Boosts Solar Efficiency - 0 views

  • Xtreme Energetics has investigated the possibility of using mechanical trackers to perform the same light-focusing duties as other solar array manufacturers have. However, HP’s transparent transistor can do the job electronically, rather than mechanically, and significantly reduce the costs of such an installation. Such a solar array is known as a concentrating photovoltaic (or CPV) solar array. To date, CPV arrays are fairly expensive and cannot store energy, making them less useful. They also work best in specific sections of the world — those with the highest levels of solar radiation, such as the southwest United States and northern Africa.

Space storm alert: 90 seconds from catastrophe - space - 23 March 2009 - New Scientist - 0 views

  •  
    Interesting article from New Science describing how a "coronal mass ejection" from the Sun could melt down the electrical power gird. ".... Over the last few decades, western civilisations have busily sown the seeds of their own destruction. Our modern way of life, with its reliance on technology, has unwittingly exposed us to an extraordinary danger: plasma balls spewed from the surface of the sun could wipe out our power grids, with catastrophic consequences..." The article does offer a solution: upgrade the ACE solar satellite, to detect an electro magnetic surge and provide power grid operators with about 15 minutes to shut down their systems. The article does not discuss another possible option: stop building centralized power sources that demand increasingly massive power grids. Instead, concentrate on meeting energy needs using localized sources of power; like the highly portable Hyperion Power Module.

Land Art Generator Initiative - 0 views

  • It is important to note is that there is a lot more out there than what we see in the everyday. In fact, you will see here that there are dozens of proven methods of harnessing the power of nature in sustainable ways. Some of the more interesting examples that may be applicable as a medium for public art installations are the translucent thin films which can be flexible and offer interesting hues and textures, piezoelectric generators that capture vibration energy, and concentrated photovoltaics, which allow for interesting play with light. But the possibilities are endless and new designs are coming into the market all the time that can be artistically integrated into beautiful sustainable infrastructure.

Washing Carbon Out of the Air: Scientific American - 1 views

  • Machines with filters made from sorbent materials can bind carbon dioxide, extracting it from the air. With mass production,machines might capture CO2 at $30 a ton, less than the $100 or more charged for commercial CO2 supply. With improved sorbents, 10 million machines across the planet could reduce CO2 concentration by five parts per million a year, more than the rate of global increase right now.

DailyTech - MIT Students Develop Revolutionary Solar Dish That is Hot Enough to Melt Steel - 0 views

  •  
    The solar industry is booming. With waves of investment and grants, the solar power industry is for the first time becoming a serious business. New power plants will soon be pumping power out to consumers, while other firms market to sell panels directly to the consumer, providing them with a more direct means of experiencing solar energy.

Sopogy thinks small to make megawatts of solar power | Green Tech - CNET News.com - 0 views

  •  
    If giant solar thermal power plants spread across the desert are like a mainframe, Sopogy is making the equivalent of a personal computer. The Hawaii-based company on Tuesday at the Intersolar 2008 conference will show off the latest version of its MicroCSP--essentially a shrunk-down version of concentrating solar power (CSP) equipment used in power plants.
