Four turbines at the Smøla wind farm in Norway are to have one rotor blade painted black to see whether increasing the visual contrast of the turbine against its background might help to reduce bird strikes.
The principle of harnessing osmosis has the potential to produce enormous amounts of energy anywhere that salt water and fresh water meet. We looked at some of the approaches to turning this theory into reality earlier this year
, including Statkraft's plans to build a prototype power plant. The company's plans are now coming to fruition with Her Royal Highness Crown Princess Mette-Marit of Norway officially opening the world's first osmotic power plant prototype on November 24.
Green energy comes in many guises these days, from wind-power to wave-power. One of the more compelling of the new kids on the eco-energy block is salinity power, which uses the concurrence of salt-water and freshwater in estuaries and marries it with the natural, effortless process of osmosis.
