In general, ultracapacitors are great solutions whenever the power demand is high, but the duration is short. For example, we are expanding into the diesel truck market, where the high power demand of engine starting can place a great strain on the batteries, greatly lowering their useful life.
The Hybrid Renewable Energy Forecasting (HyREF) solution combines big data analytics and weather modeling technology to accurately forecast the availability of wind power and solar energy.
The implementation of ASIC based current transducers opens up functionality that the traditional discrete component transducers could never achieve.
On Tuesday, the U.S. Department of Defense announced a total of 22 new defense contracts worth a combined $7.59 billion. Notwithstanding the large headline number, one single contract accounted for 92% of the funds on offer. This contract, a massive $7 billion deal to supply solar energy "from renewable and alternative energy production facilities that are designed, financed, constructed, operated and maintained by private sector entities," involves some 22 separate companies. Taking the form of a multiple-vendor, indefinite-delivery/indefinite-quantity, firm-fixed-price, non-option, non-multiyear contract, vendors will bid against each other to sell solar energy to the U.S. Army in response to individual "task orders" issued by the U.S. Army Corps of Engineers. Once won, a task order will be funded out of the $7 billion "pot" of funds allocated under this master Power Purchase Agreement. Bidders who won the right to compete for these task orders number 22, out of a total of 114 bids submitted. Most of the winners are either small, privately held concerns or small subsidiaries of foreign energy utilities whose stocks are not listed in the U.S.
Chinese solar-panel makers received subsidies, a European Union investigation showed, increasing the likelihood of EU tariffs on imports of the renewable-energy technology from China to counter trade-distorting government aid. The European Commission has concluded in a probe opened last November that Chinese manufacturers of crystalline silicon photovoltaic modules or panels, and cells and wafers used in them, benefited from preferential lending, tax programs and other aid, an EU official said today in Brussels. The inquiry is one of two that the commission is conducting into alleged unfair Chinese trade in solar goods -- the biggest EU commercial fight of its kind. The commission, the 28-nation EU’s regulatory arm, on Aug. 2 approved an agreement with China to curb Chinese shipments of solar panels as part of a parallel probe into below-cost sales, a practice known as dumping. The accord, which took effect Aug. 6, sets a minimum price and a volume limit on EU imports of Chinese solar panels until the end of 2015. Chinese manufacturers that take part are being spared provisional EU anti-dumping duties as high as 67.9 percent.
Solar panel satellite could beam a THIRD of humanity's power to Earth by 2025, claims former Nasa engineer
A cocktail glass-shaped satellite that could provide a third of the world's required energy by 2025 is being developed by Nasa. The design was created by Dr John Mankins who was commissioned by Nasa to explore the possibility of using solar panels in space to send energy to Earth. What Dr Mankins came up with was an incredible floating satellite named the SPS-ALPHA, or Solar Power Satellite via Arbitrarily Large PHased Array. n a recent interview with Becky Ferreria at Motherboard , Dr Mankins claimed that, depending on funding, SPS-ALPHA could be launched by as early as 2025. 'A single solar power satellite would deliver power to on the order of a third of humanity—not all at the same time, but any of that market could, in principle, be addressed,' he said. The technology would mean that energy would beamed down to Earth where power stations would pick it up and farm it out to customers. The system would be made up of thousands of thin, curved mirror-like pieces which could move around to ensure that they picked up as much sun as possible. The inside of the SPS-ALPHA would also be lined with photovaltic panels which convert the sun’s energy into microwaves. These microwaves would then be beamed down to Earth out of the bottom end of the ‘cocktail glass’.
Writing in The Telegraph last week, Ambrose Evans-Pritchard cited theU.S. Department of Energy as the basis for a prediction that the cost of solar power would drop by 75% between 2010 and 2020. Evans-Pritchard writes: The US Energy USEG +2 .12% Department expects the cost of solar power to fall by 75% between 2010 and 2020. By then average costs will have dropped to the $1 per watt for big solar farms, $1.25 for offices and $1.50 for homes, achieving the Holy Grail of grid parity with new coal and gas plants without further need for subsidies. Evans-Pritchard mentions several development projects sponsored by the U.S. Department of Defense as representative of the broader research effort that will drive costs down costs and drive efficiencies up. Over the past few years, the cost of solar power systems has plunged as the result of what some folks have characterized as Chinese “dumping.” For better or worse, I am among those “folks” who suspect that anti-competitive trade practices have fueled overly optimistic forecasts of future costs reductions. Excluding these trade-induced (and temporary) cost reductions, is it possible that solar costs could reduce costs 75% by 2020?
Advances in solar cell technology can make drones a more powerful tool not only for the battlefield but also for civilian uses, such as firefighting, crop surveying and oil and gas field monitoring. A Silicon Valley company called Alta Devices has been working with AeroVironment to engineer a drone that can stay airborne longer and carry out missions that are impossible before. The result of the collaboration is a 13-pound prototype drone that can fly for 9 hours and 11 minutes, AeroVironment announced recently. The military contractor credited its new battery and Alta’s solar technology for the feat. A drone similar to the one by AeroVironment typically can fly for one or two hours before it has to land and recharge, said Chris Norris, Alta’s CEO. AeroVironment’s new battery is good for three hours. By embedding Alta’s ultra thin and highly efficient solar cells on the aircraft, the battery is able to recharge twice before daylight fades and keeps the drone in the air three times longer, Norris added. California-based AeroVironment is still tinkering with the design of the drone, which is part of its Puma AE line. It plans to roll out a design that it could produce and sell in early 2014.
A prototype of India’s first floating solar power station could soon be coming up in the pond of Victoria Memorial. If the plan proves to be a success, such floating solar power stations could also be set up in the water reservoirs and dams of hydroelectric power stations thereby increasing their output. “Developing a floating solar power station would prove to be a revolutionary step as it could solve the perennial problem of land. Such pilot projects are also going on in a few countries such as France and Australia,” said SP Gon Choudhury, an international expert in solar energy and the brain behind this project. The idea is simple. A raft like platform fitted with hollow plastic or tin drums would be floating on water. The power generating equipment such as solar panels would be fitted on this raft so that they can float on water. It would not only solve the problem of land but would also help conserve water in the water bodies. The solar panels, which would be floating on water, would cut off the direct sunlight and hence slow down the rate of evaporation. “Studies have also shown that if the rear surface of solar panels are kept cooler, then their ability to generate power goes up by 16%. As these solar panels would be floating on water, they are expected to stay cool and hence we can generate more power than those set up on land,” Choudhury said.
A White House official confirmed to the Washington Post on Thursday that installation of solar panels began this week on the First Family’s residence. The plan to use solar energy was first revealed in October 2010, but was not put into effect until now. During a GreenGov symposium at George Washington University, then-Energy Secretary Steven Chu announced the plan to install American-made solar panels in the spring of 2011. “This project reflects President Obama’s strong commitment to U.S. leadership in solar energy and the jobs it will create here at home,” Chu said at the time. “Deploying solar energy technologies across the country will help America lead the global economy for years to come.” This is not the first attempt to include solar power in the White House’s energy mix. In 1979, President Jimmy Carter installed panels on the roof, which were taken down by President Ronald Reagan in 1986.
Africa has a huge untapped potential for generating clean energy, including enough hydroelectric power from its seven major river systems to serve the entire continent's needs, as well as enormous potential for other energy sources such as solar, wind and geothermal.
