 Salt in the absorption tube is heated to 500 °
By using molten salt instead of oil to solar power stations more efficient, But one problem is that the salt can "freeze".
Solar power plants that generate electricity using concave mirrors, directed against the sun's rays, one absorption tube in the mirror focus. In pipe flows usually oil is heated to about 400 ° C and pumped to a heat exchanger that heats water into steam, which, through a turbine and generator generates electricity.

 Nuclear technician do a test in a French research reactor. Now the Swedish one million invested in the development of a future French advanced reactor that will use the spent nuclear fuel to produce plutonium.
On 12 August last year the government decided, with the then Research Tobias Krantz in the lead, investing in nuclear technology research and education in cooperation with France. The initiative is described as the biggest state in the area since the 80s.
The case was on a secret list, a shadow list, internally called B list, and the decision and the subsequent agreements confidential.
The investment in nuclear technology is part of a larger Swedish-French cooperation, which also includes research on accelerator technology and climate, covering over half a billion dollars.

 Vattenfall's wind turbines in the North will be installed with the help of a ship that can fold out six legs and become a platform. Pacific Orca is 160 meters long, weighs 8400 tons and has a cruising speed of 14 knots
The ship has two cranes and six legs that can be folded down so that the ship can support the bottom when the turbines and towers will be installed and erected in the lake.
The first job of the newly built ship Pacific Orca is to load 80 pieces of 3.6 MW turbines from Siemens in the port of Esbjerg and transport them to Vattenfall and the German utility company Stadtwerke Munich wind farm Dan German, about 70 kilometers west of the island of Sylt in the German part of North Sea.

Very light in homes and on the streets is a trend that continues. At the same time another development. Since 1 September 2009 and April 1 this year, the bulbs and other inefficient lighting started to be phased out from our homes, offices, roads and industries, to be replaced by more efficient alternatives. The change is due to the Ecodesign Directive, the EU legislation that sets basic requirements for energy efficiency in energy-related products.

The world faces a severe energy supply problems: How will the increased energy demand be met, while climate targets are met? The debate can sometimes get the feeling that increased energy demand is trivial and that only the bottoms of the people want more appliances that make life more comfortable.
