| No power from Sterling first day |

There was a sense that solar power plant in Sege Park in Malmo would begin to supply power to the buildings in the park at the moment Ilmar Repalu pressing the green start button. To be Sweden's first solar power plant with Stirling Technology at the City of Stirling technology capital of Malmo is sufficient even if the sun shines. Sterling engine was developed by Kockums in Malmö and is based on the same technology as high-profile Kockums submarine engines, but are smaller in size. Solar power is the engine of 25 kW and was originally developed by Kockums as a car engine in the 1980s. But Sterling engine in the car was a dead end. Instead Kockums continued to develop 25 kW engine for solar thermal power, which has five times as high efficiency solar cells as and three times higher than so-called parabolic trough. Kockums 25-kW motors are already in the U.S. by the company Stirling Energy Systems and are now also produced by Energy AB in Sibbhult in Scania. - SES are more advanced than us in the sense that the SES produced more machines than we are. But we are on the other hand, had access to a more modern technology than the SES had plans to. And we have a closer cooperation with Kockums Stirling people of, say Ripasso technology manager Tore Svensson for New Technologies. Solar Power Authority works like this. Stirling engine is suspended above a 100-square-foot solspegel, which transmits concentrated solar heat into the engine and heats it to 700 degrees. The engine is powered by the hydrogen contained in the engine closed systems alternately heated and cooled. It's the Sterling principle - a hot-air engine. Kockums engine is reported to have an efficiency of 30 percent and with the size of solparabolen which we are now in Malmo generate any solar enough electricity for two electrically-heated homes. Demonstration power plant in Sege Park in Malmo, responsible for some of the energy needs of the municipal buildings in the park. |
