New Project to Deliver Solar Power After the Sun Goes Down

The holy grail of renewable energy is a solar power plant that continues producing electricity after the sun goes down. A California company has taken a step toward that.

…s license application.
So-called dispatchable solar farms would in theory allow utilities to avoid spending billions of dollars building fossil fuel power plants that are fired up only a few times a year when electricity demand spikes, like on a hot day.

SolarReserve is literally run by rocket scientists, many of whom formerly worked at Rocketdyne, a subsidiary of the technology giant United Technologies. Rocketdyne developed the solar salt technology, which was proven viable at the 10-megawatt Solar Two demonstration project near Barstow, Calif., in the 1990s.
United Technologies has licensed the technology to SolarReserve and will guarantee its performance a crucial advantage for the startup when it seeks financing from skittish bankers to build the Rice solar farm.
As many as 17,500 large mirrors each one 24 feet by 28 feet will be attached to 12-foot pedestals. The mirrors, called heliostats, will be arrayed in a circle around a 538-foot concrete tower.
Atop the tower will sit a 100-foot receiver…

Entire State of Texas Could be Powered by Solar

148,000 megawatts of power could be generated by just one form of solar, and there are many that could be used.

…The point of building these solar plants is to make Texas a self sufficient state that has a clean burning, permanent way to provide energy to its resident. I do not know much about the Texan geology but I have never heard about Texas being abundant in Uranium or other nuclear fuels. One thing that Texas does have is plenty of sunshine. Texas using solar power is pretty much the same as the great plain states using wind turbines. While the initial cost is a lot to ask for, it is for the long term. The cost over the period of time should be reasonably low as long as the plants do not get into disrepair. In addition, using the solar energy does not leave any waste behind. While the waste may not initially be a big deal, it will accumulate over the years and eventually turn into a big deal. While 11 900 square miles is very big, Texas is also a very big state. Texas is over 250,000 square miles which means 11,000 square miles is not really a big deal. Plus, since the whole state receives pretty much the same…

Top 12 Solar Powered Aircrafts

Incredible solar powered aircrafts ready to change the way we’ll fly in the green future.

…Designer: Eric Raymond
Eric gave shape to Sunseeker after years of hard work, changes and innovations on wings of Larry Mauro’s SOLAR RISER, Paul MacCready’s SOLAR CHALLENGER, and Gunther Rochelt’s MUSCULAIR II. The project kicked off in 1986 and was given the final shape in 1989-90 with help of Sanyo and other corporations.
11. SOLONG

Designer: AC Propulsion
Type: UAV
Weight: 10.8 kg
‘SoLong’ stands apart by flying continuously for over 24 hours by battery and solar power.
10. Solar-Powered Robot Bird

Designer: University of Missouri-Rolla
Flying Altitude: 30,000 to 40,000 feet
Unique features: World’s first flapping-wing unmanned solar aircraft
This solar-powered bird is literally an eagle and apparently is world’s first flapping-wing unmanned aircraft that runs on solar energy. Designed by researchers at the University of Missouri-Rolla with the help of NASA, the aircraft uses thin-film solar arrays and special shape changing material hence making it more flexible and efficient than the Mars…

Solar Panels Could Power 10% of US By 2025 (From 0.1% Now)

Solar energy currently generates .1% of the electricity used in the U.S. According to a study released today, this will change rapidly as the cost of electricity increases and the cost of solar energy drops.

…Donnell, executive vice president of Ausra. Solar effectively generates electricity when the rates and demand are the highest.
Action is Needed to Advance Widespread Use of Solar Energy
Solar Companies
Large-scale use of solar energy depends on prices dropping to $3 per peak watt of electricity by 2018, according to the study. This involves quickly implementing advanced technologies in a cost-effective manner. Solar technology needs to be easier to install, thus reducing installation costs and other installations barriers.
Utility Companies
Utilities have become more and more interested in solar energy. California is a great example, where many utilities have signed purchase agreements for solar plant output. The U.S. will also need trained workers, which is another opportunity for utilities to take the lead.
A large investment in solar energy is needed for…

The Largest Solar Farm in North America Coming in 2010 to Canada (40 MW)

A California company is preparing to install a massive solar installation near Sarnia, Ontario that will be the largest solar installation in North America.

…Optisolar and others have 3 years to build these solar facilities from the day that they obtain approval from the OPA. This means that most of these systems probably won’t be fully operational until 2010. The job creation coming from solar power is higher than any other renewable energy technology. This prompted many anti-solar officials in Germany to change their mind about the solar program there when they came into power. It is about time that Canada benefited from the cleantech boom. The main reason folks support large scale solar support programs is that they are frustrated that the other technologies cannot be ubiquitous. Wind Energy is wonderful but at a certain penetration it is alot of trouble because it often produces power when residents don’t use it. Also it is almost always central generation, limited by transmission capacity. Biomass is fraught with long term risk. Over a 40 year time period the sources and uses of fuel changes. There are only a limited number of projects that make sense from a…

Space-Based Solar Plant Gets Go-Ahead

The nation’s first space-based solar power plant, approved on Thursday by California regulators, is supposed to be turned on in 2016.

…s hard to argue with the audacity of the project.
Michael Peevey, California Public Utilities Commission

A Southern California start-up called Solaren will loft components for the solar power plant into orbit and sell the electricity it generates to Pacific Gas and Electric, the major utility in Northern California, under a 15-year contract. The project is supposed to be turned on in 2016.

Solaren, founded by veterans of Hughes Aircraft, Boeing and Lockheed, plans to deploy a free-floating inflatable Mylar mirror one kilometer (0.62 miles) in diameter. This will collect and concentrate sunlight on a smaller mirror, that in turn will focus the rays on photovoltaic modules, according to the…

China Offers Big Solar Subsidy, Shares Up

China has launched an unprecedented and long-awaited plan to offer subsidies for utility-scale solar power projects, sparking a rally in shares of Chinese solar panel makers on Tuesday.

…As the world’s top greenhouse gas polluter, China is trying
to catch up in a global race to find alternatives to fossil
fuels, blamed for carbon emissions affecting the planet’s
climate.

Expectations of such a move by China have underpinned a
rally in Chinese solar stocks for much of this year.

Several analysts warned on Tuesday, however, that the
subsidy program, although positive, would not lead to a
near-term pickup in solar panel demand. The solar industry has
suffered this year from a lack of available financing for
renewable energy projects due to the financial crisis.

“The China news, in our view, is providing good PR for
China-based companies,” FBR Capital Markets analyst Mehdi
Hosseini wrote in a note to clients. “Yet, in our opinion, it
may be insufficient to offset the expected shortfall in 2009
earnings expectations. We simply do not believe that the full
extent of disappointing results is baked into stock prices.”

The Ministry of Finance said the government will subsidize
50 percent of…
