From: habshi on 1 Jun 2010 19:28 This makes my idea of transporting hot air from the tropics to the cold north via insulated vacuum pipes feasible. It can also cause cooling in hot climates. So heat from California in the summer could be used to heat greenhouses in the Canadian north , and cold air rushing down in another pipe would allow cheap air conditioning excerpt The tubes are made of stainless steel and painted black but encased in the airless vacuum of a glass tube. Birds can land on the glass tubing and not be roasted, Gnecco said. Each frame also holds a tube a few feet in front of the mirrors. The tube contains a synthetic, oil-like fluid that costs $15 a gallon and is designed for heating to 740 degrees. The hot fluid flows through a separate component that acts something like a boiler to create steam. Nearly 150 miles of pipe and related plumbing, some as much as 30 inches in diameter, will hold 1.2 million gallons of the synthetic fluid. http://www.orlandosentinel.com/news/local/os-fla-mirror-solar-plant-20100601,0,7298705.story
