This allows the luxury for those who can afford it of running a hot water boiler (15 amps) and heaters (12 amps) in the winter, and a couple of one-ton air conditioners (5 amps each) in the summer.
The astronauts hooked up the six-and-a-half-ton air lock on July 15 after the station's 58-foot robot arm hoisted it from the shuttle's cargo bay.
The primary job of moving the 6.5-ton air lock and the four 1,200-pound 1,200-poundre gas tanks from the shuttle cargo bay to the Unity node will be left to the new 57-foot station arm, a robotic construction crane called Canadarm2.
In front of it stood a five-ton air-conditioning unit, and somewhere in the distance an oil-fired generator was producing the electricity to power the unit.
Nine 5-ton, 8-ton and 10-ton air-conditioning units usually keep the church cool, but this indoor heat was not a matter for an air-conditioning specialist.
I set this on medium and the fan silently pushes a ton of air.
The site actually got a ton of air time, and even featured co-founder Susan Feldman (pictured in the post with Turner).
For example, the urban forest of Washington, D.C., is estimated to store about 526,000 tons of carbon and to remove about 540 tons of air pollution a year (Nowak 2006a); the urban forest in Casper, Wyoming, is estimated to store about 37,000 tons of carbon and to remove about 50 tons of air pollution per year (Nowak 2006b).
Other consequences of fracking highlighted in the report included: 450,000 tons of air pollution a year and 100m metric tons of global warming pollution since 2005.
According to Environment America's numbers, in the last eight years fracking has generated 280 billion gallons of waste water, damaged 360,000 acres of land, released 450,000 tons of air pollution a year, and added about 100 million metric tons of greenhouse gas to the atmosphere.
Michael G. Carey, the agency's president, said putting a rail car float system into operation at the yard "could potentially divert approximately two million tons of freight a year from truck to rail and eliminate tons of air pollutants annually".
