Major Breakthrough In Solar Energy: 'supercritical' Steam Generated - National News | Examiner.com

Solar-Power Buyers at Risk of Being Ripped Off, Says Arizona Attorney General Tom Horne | Phoenix New Times

horneglummy.JPG The Commonwealth Scientific and Industrial Research Organization (CSIRO) believes this could be the first step toward large-scale power stations fueled by solar energy instead of gas or coal. "It's like breaking the sound barrier; this step change proves solar has the potential to compete with the peak performance capabilities of fossil fuel sources," said Dr. Alex Wonhas, CSIRO's Energy Director, according to Gizmag . "Instead of relying on burning fossil fuels to produce supercritical steam, this breakthrough demonstrates that the power plants of the future could instead be using the free, zero emission energy of the sun to achieve the same result." The researchers used more than 600 directional mirrors known as heliostats to convert pressurized water in a receiver into supercritical steam, which then powers turbines and creates electricity. This process has worked for solar thermal power plants that run on subcritical steam, but those operations could not match the efficiency or output of the worlds most state-of-the-art fossil fuel power plants, according to CSIRO . Using this latest advancement, those plants could be converted to supercritical levels, which would vastly increase their efficiency and could help significantly lower the cost of generating solar electricity while negating the need to use fossil fuels to achieve the same result, Gizmag says. Despite this heart-racing development, CSIRO says that commercial development for the technology, may be a fair way off. "It's important to remember that what we've done is really the first step along a fairly long path still in demonstrating that we can actually do these things with solar technologies, says project leader Robbie McNaughton. Nevertheless, the announcement signals that, when it comes to large-scale power stations, solar energy may soon be ready to move up to the big kids table.

Father slams teacher with baseball bat for texting his 15-year-old daughter. On Monday, he filed a formal response denying the claims by a former employee that he conducts campaign business illegally on state time. The Citizens Clean Elections Committee and state Secretary of State's office will figure out whether Horne did anything improper. The evidence so far seems to suggest he did. Horne's facing calls for his resignation and the prospect of having to return $400,000 in donor contributions due to a previous campaign-related scandal. In these cloudy times for his campaign, he's throwing a cloud over Arizona's rooftop solar industry. Maybe it'll help him, considering that most of the opposition to solar is found in conservative circles. The national Solar Energy Industry Association didn't appreciate Horne's message, saying the state AG " fails to point out that for some solar systems, depending on application, location, and financial incentives, the payback period can be as little as four years." Four years, huh? Not if the Arizona Corporation Commission allows Arizona Public Service to charge solar users more fees . To Horne's (potentially tainted) point, you've got to check out these sorts of claims before signing on the proverbial line which is dotted . UPDATE: Solar companies, through TUSK, responded to our inquiry and blasted Horne for using "questionable judgment:" "We enthusiastically agree it's always good practice for consumers to do their homework before making a purchase," said the solar-company group, fronted by Rose and Goldwater Jr.

Solar power gains momentum after long struggle in Texas | Dallas Morning News

The development of solar power has taken off in recent years around the world, but particularly in the Middle East, where a day rarely goes by without long periods of the sun's radiation beating down on the desert sands. Over the past decade, investment in solar energy has skyrocketted, with $5bn spent in 2003 leaping to $93bn today, according to the Solar GCC Alliance . Rajendra Pachauri, chairman of the Intergovernmental Panel on Climate Change, visited the solar-panel factory for Sunday's inauguration. "What impresses me is that it's driven by a visionary view of what we should be doing for the future," Pachauri told Al Jazeera, adding the facility is "beyond state-of-the-art". "Yes, Qatar has extremely high [greenhouse gas] emissions, but I suppose the beginning of a journey starts with the first step. And would commend the fact that they are looking further into the future than most countries are." RELATED: The Gulf's bright solar-powered future Neighbouring Saudi Arabia has announced plans to produce 41 gigawatts of solar energy capacity to fuel its domestic needs by 2032, and has begun building massive solar power plants throughout the country. It is the largest proposed solar target in the world, however, it remains to be seen when production will commence. Fezzami wouldn't provide his company's production estimates, costs, or name potential investors, saying success "depends on the market". "When the demand is there, we'll be ready ... There is nobody else producing 300 megawatts in the region," he said. Qatar Solar Energy board member Kamal Onadjela said 300 megawatts would provide enough energy for 100,000 homes each year in high energy-consuming countries such as Qatar or the US. While the solar industry continues to show promise, issues such as how to hold onto the energy once captured from the sun remain an obstacle.

Qatar sheds light on its solar-power future - Yahoo News UK

The solar industry has driven prices down to where solar can compete. Recurrent announced plans last month to build a 150-megawatt solar farm in West Texas after signing a 20-year power purchase deal with Austin Energy. That comes just months after First Solar, one of the worlds largest solar companies, began construction on a 22-megawatt farm near Fort Stockton with plans of eventually expanding to 150 megawatts. From small rooftop systems to Texas largest installation, a 39-megawatt solar farm in San Antonio, the state counts less than 220 megawatts of solar power. On a per-capita basis, that is nearly the lowest in the country. But with almost 350 megawatts of new capacity scheduled to be built by 2016, that is likely to change. And an even more dramatic acceleration could be ahead. Solar developers have been flooding the states grid operators with applications for more solar farms, close to 2,000 megawatts worth, said Warren Lasher, director of system planning for the Electric Reliability Council of Texas. Its hard to say how much will actually get built, he said. Its been this way for more than a year.

Delhi eyes rooftop solar power - The Times of India

Gandhinagar's rent-a-roof project may help Delhi supplement the power supply in the capital with solar energy. If the model is replicated in Delhi, according to official sources, it has the potential to deliver 50-100 MW. This was discussed by the capital's top bureaucrats with their Gujarat counterparts on Thursday. On the direction of LG Najeeb Jung, three teams of senior officials have gone to the state to study the Gujarat model. The two-day visit ends on Friday. Among the other things they are looking at are Ahmedabad's Sabarmati riverfront project and the CCTV-based city surveillance system in Surat. On Thursday, the teams visited the river and several solar power projects. Senior officials told TOI that under the rent-a-roof project, residents give their rooftops on hire to private solar energy companies who in turn pay them Rs 3 for every unit of energy produced. Similarly, rooftops of government buildings like schools and hospitals are also leased out for solar panels. A team, headed by Delhi's principal secretary (power), visited several solar power projects, including the ones at Gandinagar secretariat, fly ash dyke and houses where solar power is being generated on terraces. The team also met Mr.
