According to Desertec Foundation company's press release, project developer Nur Energie and its Tunisian partners, including Desertes Foundation plan to construct concentrating solar-thermal power (CSP) plant in the Saharan deserts of Tunisia. The project, which called "TuNur" will construct in several phases. The first phase is expected to begin in 2014 and the first electricity exports are set to reach Europe by 2016 via a new low-loss transmission line to Italy. The project has been designed to reduce water requirements to a bare minimum by using a dry, air-based cooling system. It will ultimately produce 2 Gigawatts of electricity, roughly double the average nuclear power plant. The number of jobs created directly and indirectly over the project's construction and operational period will come to around 20 thousand. Around 825 thousand flat plate mirrors and steel structures known as heliostats will be needed for the project and can be manufactured locally. Using heat storage tanks, "TuNur" can produce electricity on demand day and night, delivering enough clean electricity to power 700 thousand European homes. Desertec Foundation was established in 2009. It is an international consortium, whose goal is to provide Europe with solar electricity. The consortium includes such major European companies, as ABB and Siemens, Deutsche Bank, insurance company Munich Re, energy company RWE and so on. Desertec Foundation reported, that investors are willing to invest about 400 billion euro in solar electricity. They plan to construct solar power plants in Africa and the Middle East and to occupy about 15 percent of European electricity market.

Work on the world's largest solar bridge formally begins, as the first of more than 4.400 solar panels are installed above the new "Blackfriars" station platform, reported The Guardian. When complete in 2012, the "Victorian" bridge will play host to some 6 thousand square meters of photovoltaic (PV) panels, making it London's largest solar array. The historic London site is undergoing a multi-million pound refit, which includes extending the platform along "Blackfriars Bridge", a structure built in 1886. "Solarcentury", the UK company, managing the installation, expects the panels to generate around 900,000kWh of electricity a year, providing half of the station's energy and reducing annual CO2 emissions by an estimated 511 tons. "Station buildings and bridges are fixed parts of our urban landscape and it is great to see that this one will be generating renewable energy every day into the future. For people to see that solar power is working is a vital step towards a clean energy future," said "Solarcentury" chief executive Derry Newman in a statement. Other energy saving measures, such as rain harvesting systems and sun pipes for natural lighting, are also being fitted at "Blackfriars", as part of Network Rail's plans to reduce carbon emissions by 25 percent per passenger kilometer by 2020. One other solar bridge is known to exist, "The Kurilpa" footbridge in Brisbane, Australia, although 16 thousand solar panels were laid on the top of a train tunnel in Belgium earlier this year.

Last week California's Governor Jerry Brown was joined by U.S. Secretary of the Interior Ken Salazar for the ground breaking ceremony of the world's largest solar thermal facility near Blythe, California, reported constructiondigital.com. Once construction is completed, the site will feature four solar thermal power plants with a total generating capacity of 1,000 megawatts of electricity. This would be enough energy to power 800,000 (corrected by construction.am according to the US Energy Department data) American homes using a clean, domestic source of fuel. Blythe Solar will cover about 7,025 acres of land. Governor Brown praised the solar power plant as a key step toward his goal of building a green economy of the future in California."We're going to be the world leader in solar energy," Brown said during the groundbreaking ceremony. Preparations for the facility have been underway since 2010, with early work already being done on the first two solar power plants that will be able to generate 242 megawatts of electricity. The first two plants are expected to be operational and connected to California's power grid by 2014. In April the Blythe solar project received a loan guarantee of $2.1 billion from the US Federal Financing Bank. The total projected cost of the project is expected to reach about $2.8 billion. The facility is being built by the Solar Trust of America and the Solar Millennium Group, two of the world's top producers of solar thermal technology. The Solar Millennium Group built the first operational parabolic trough power plants in Europe. Parabolic trough is the only type of solar technology that has been proven since the 1980s to be able to produce enough electricity for commercial use in large power plants.

As reported by Inhabitat.com, last week South Korea inaugurated the world's first solar-powered and largest floating island on Hangang River in Seoul. With two more islands slated to open in September, the recently opened Viva is already drawing crowds en masse with its first-rate entertainment complex. The stunning structure includes a 700 seat convention hall, restaurants and arcades - all powered by solar energy. When the development is completed, the trio of islands will be linked together by twenty-three weather-proof chains. Seoul's man-made islands differ from those common to Dubai, which are constructed by building up sand on the ocean floor. Viva, and its satellite islands, instead float, and are buoyant on the river's surface. Should there be a flood, the islands while rise and fall with the water levels, rather than be flooded over. A high tech tracking system will alert a controller should the islands float too far from their home site, due to changing water levels. Supported by 24 giant airbags, Viva weighs in at 2,000 tons, but can support building facilities up to 6,400 tons. The island will be harnessed by chains to a 500 ton concrete block to keep it in place. The three story building which holds all facilities is covered with 54 square meters of solar panels, which produced 6 kilowatts of energy each day, providing the facilities below with electricity, and also illuminating the facades at night. The $83.9 million dollar government project includes the 3.2 thousand square meters Viva, 1.3 thousand square meters Vista and nearly 371 square meters Tera. Combined, they will host international conventions, water sports events, restaurants, cultural performances and exhibitions. All three islands should be open by late August 2011.
