TG Daily - New solar cell material achieves almost 100% efficiency, could solve world-wide energy problems - 0 views

  •  
    Researchers at Ohio State University have accidentally discovered a new solar cell material capable of absorbing all of the sun's visible light energy. The material is comprised of a hybrid of plastics, molybdenum and titanium. The team discovered it not only fluoresces (as most solar cells do), but also phosphoresces. Electrons in a phosphorescent state remain at a place where they can be "siphoned off" as electricity over 7 million times longer than those generated in a fluorescent state. This combination of materials also utilizes the entire visible spectrum of light energy, translating into a theoretical potential of almost 100% efficiency. Commercial products are still years away, but this foundational work may well pave the way for a truly renewable form of clean, global energy.

The ART of the Feed-in Tariff | celsias° - 0 views

  •  
    Feed-in Tariffs in 70 words or less: Government and power utility offers premium, long-term contracts to residential, commercial, and industrial citizens to generate power on-site. Rates are based on the cost of buying and installing various renewable energy systems, but only paid on actual power produced. Citizens purchase back grid power, as per usual, from utility at regular prices. Increase in cost is paid for with a small surcharge to all electricity ratepayers.

One Wash, One Cup of Water: Nearly Waterless Washing Machine Invented - 0 views

  •  
    British inventors have designed a washing machine that takes eco-friendliness to a new level: it uses just a single cup of water to wash a load of clothes. Instead of water the Xeros machine uses thousands of special plastic chips (about 44 pounds' worth) in each wash, and when that single cup of water is heated, these chips absorb the dirt-including tricky stuff like coffee and lipstick. The chips are removed when the wash ends, and can be reused up to 100 times. Though it's still in prototyping, the inventors are intending to commercialize their machine, and it may even hit the shops next year for a price similar to conventional machines.

Philippe Starck Makes A Come Back, Designs Mini Wind Turbine ( philippe, starck,, designer,, wind, turbine,, mini, wind, turbine,) - 0 views

  •  
    Personal wind turbines are more often invented than actually manufactured. Those that make it to the commercial stage are mostly available at several thousands of dollars. That's why it is all the more surprising that as of next September you'll be able to buy a true designer windmill for way less than that.

Graphene Shows Potential of Storing Large Quantities of Renewable Electrical Energy - 0 views

  •  
    Engineers and scientists at The University of Texas at Austin have achieved a breakthrough in the use of a one-atom thick structure called "graphene" as a new carbon-based material for storing electrical charge in ultracapacitor devices, perhaps paving the way for the massive installation of renewable energies such as wind and solar power. The researchers believe their breakthrough shows promise that graphene (a form of carbon) could eventually double the capacity of existing ultracapacitors, which are manufactured using an entirely different form of carbon. "Through such a device, electrical charge can be rapidly stored on the graphene sheets, and released from them as well for the delivery of electrical current and, thus, electrical power," says Rod Ruoff, a mechanical engineering professor and a physical chemist. "There are reasons to think that the ability to store electrical charge can be about double that of current commercially used materials. We are working to see if that prediction will be borne out in the laboratory."

Ecofasa turns waste to biodiesel using bacteria - AutoblogGreen - 0 views

  •  
    A group of Spanish developers working for a company called Ecofasa just announced a new biofuel made up from trash. This isn't a biodiesel made from used frying oil; instead, it's made from general urban waste which is treated by bacteria. The result of that bacteria? Fatty acids that can be used to produce standard biodiesel. According to the company's CEO, the process is fully biologic, competes with no feedstock and is really sustainable. However, the process doesn't yield that much actual fuel: just one liter of biodiesel from 10 kg of trash. The project is now in a development phase, but Ecofasa said that a commercially viable model could be ready in three to four years.

Peak Energy: Mass Production of Plastic Solar Cells - 0 views

  •  
    In a significant milestone in the deployment of flexible, printed photovoltaics, Konarka, a solar-cell startup based in Lowell, MA, has opened a commercial-scale factory, with the capacity to produce enough organic solar cells every year to generate one gigawatt of electricity, the equivalent of a large nuclear reactor. Organic solar cells could cut the cost of solar power by making use of inexpensive organic polymers rather than the expensive crystalline silicon used in most solar cells. What's more, the polymers can be processed using low-cost equipment such as ink-jet printers or coating equipment employed to make photographic film, which reduces both capital and manufacturing costs compared with conventional solar-cell manufacturing.

Solar power a strong contender (ScienceAlert) - 0 views

  •  
    Kramer Junction. Nevada Solar One. Andasol 1. Kimberlina. They're obscure names today. But they'll be household names tomorrow. The reason? Each is now providing 'here and now' proof concentrating solar power (CSP) works. That can't be said for cabon capture and storage. Nor can it be said for 'next generation' nuclear. Each faces years of additional research and development before some 'first mover' will be game enough to build one. That just isn't the case with concentrating solar power. It's got 20 years of proven commercial operation (Kramer Junction) behind it. It also has new innovations coming on line (Nevada Solar One), with solar thermal storage (Andasol 1), and the promise of super-low costs in coming years (Ausra's Kimberlina). What it adds up to is a price-declining research and development juggernaut in concentrating solar power. This is rapidly bringing concentrating solar power closer to competitiveness with dirty fossil fuels. The California Energy Commission estimates this price 'cross over' could happen by 2015. Bulls predict sooner. And in an industry where new plants and equipment can last 40 years, 5-7 years from now is like tomorrow. What this means is that for forward planning of new infrastructure, concentrating solar power is already nipping at the heels of coal. Toss in carbon prices and the reduced likelihood of protesters chaining themselves to bulldozers as they are likely to at any new coal plants, CSP starts looking like a VERY good deal indeed.

Obama to Add 20 GW of Wind Power in 3 Years : Red, Green, and Blue - 0 views

  •  
    An aide to Obama said Friday that the administration plans to add 20 gigawatts (GW) or more of wind power and 4 GW of geothermal and solar power by 2012 through loan guarantees and fast tracked national renewable energy requirements, like the Renewable Portfolio Standard. Last May the U.S. Energy Department estimated wind power could provide almost a quarter of U.S. electricity. Trade groups from the U.S. wind and solar industries were happy with the news, considering that the current economic environment for commercial credit has lowered all boats as it were, with all investment now endangered - not just investment in risky financial instruments, but even those investments in renewable energy that are essential to growing a stable economy. 4 votesBuzz up! No other country, in any single year, has added the volume of wind capacity that was added to the US electrical grid in 2007 with both wind and solar growing well over 40%, but with the credit crunch affecting all sectors of the economy, new projects could drop by as much as 50%, without help from the Federal government.

Newsvine - Organic vs Non-organic - 0 views

  •  
    How important is it to eat organic? Is it a fad, a craze or is it a warning against chemical fertilizers and GMO crops, which will help protect the next generation? Organic farming is natural farming, that means no chemical fertilisers, no genetic modification for either food crops or feed crops. Commercial farming pushing demand for agricultural produce forced a shift towards chemical fertilisers and farming methods to maximise output, for maximum profit, unaware of the significantly unnatural processes being used can be harmful. At the consumer level organic produce is a relatively new phenomena. On the supermarket shelves we are finding products labelled 'organic', most of us think it means 'natural' or 'cruelty free'. When you buy organic you are buying a green product . That means methods such as green fertilisers, crop rotation and biological pest controls are used instead of toxic chemical fertilisers and genetically modified organisms which are harmful to the land. Organic farming composes about 2% of all farming on the planet.

    The Scottish Government has created one of the biggest international innovation prizes in history - a £10 million challenge for advances in wave and tidal energy. At a ceremony this week in historic Edinburgh Castle, details of the 'Saltire Prize' were revealed to leading scientists, environmentalists and potential entrants after being finalised by a panel of international experts who comprise the prize Challenge Committee. Dr Anne Glover, Scotland's Chief Scientific Adviser and Chair of the Challenge Committee, said the Saltire Prize will be awarded to the team that can demonstrate in Scottish waters a commercially viable wave or tidal energy technology that achieves a minimum electrical output of 100GWh over a continuous two year period using only the power of the sea and is judged to be the best overall technology after consideration of cost, environmental sustainability and safety.

Peak Energy: Wave Energy to Bring Power and Jobs to San Francisco - 0 views

  •  
    CleanTechnica has a post from San Francisco mayor Gavin Newsom on the city's proposal to build a wave power plant offshore - Wave Energy to Bring Power and Jobs to San Francisco. Today, San Francisco took a meaningful step toward turning the promise of renewable ocean energy into reality. We submitted a preliminary permit application to the federal government to develop a wave power project off our coast that we believe can generate between 10 to 30 megawatts of energy, with potential of up to 100 megawatts. When this project is fully operational, upwards of 100 jobs could be created in San Francisco. Ocean power is a true "game changer" in the area of renewable energy. When wave and tidal power technologies reach commercial scale, they are expected to be able to provide thousands of megawatts of power to our coastal communities, dramatically green our energy portfolios and create thousands of new American jobs. In San Francisco, we've been doing our part to spur these technologies by aggressively advancing tidal and wave power pilot projects. We are 100% committed to this challenge. Wave power is not a new concept. In 1887, San Francisco Mayor Adolph Sutro recognized the power of San Francisco's waves and built a wave catch-basin to harness the ocean's power. Over the next century wave power development took a backseat to our dependence on oil, with oil platforms built along our coasts to feed our oil addiction.
