GreenTech Media has a report on a 38 MW solar thermal power plant planned for the Greek islands (going against recent trends suggesting solar PV is now cheaper than solar thermal power) - BrightSource Plans 38-Megawatt Plant for Crete.
Read full from the BigGav at peakenergyThe Crete project will take advantage of air cooling to convert steam back into water. (In the power plant, mirrors focus solar heat on a water tank. The resulting steam is used to turn a turbine, but then it turns back into water to begin the process over). This will reduce water consumption by 95 percent.
