It can be stored during periods of low energy demand (off-peak), for use in meeting periods of higher demand (peak load). Alternatively it can be used to power vehicles, or even tools. File:Minebw.gif Types Edit Compressed air energy storage can be done in two ways: Compression is done with an electrically powered turbo-compressor . Air is stored: In mass quantity in underground in a cavern created by solution mining (salt is dissolved away) [2]or an abandoned mine. Physics of isothermal compressed air storage One type of reversible air compression and expansion is described by the isothermal process, where the heat of compression and expansion is removed or added to the system at the same rate as it is produced.
The ideal gas law, for an isothermal process is: By the definition of work, where A and B are the initial and final states of the system: where, Edit Cars. United Metals-Boise Scrap Metal Price List.

Sweep's Library - Firewood BTU Comparison Charts. The Chimney Sweep Online Fireplace, Woodstove, Gas Stove and Barbecue Shop Here are two charts showing the weight and available heat content of one cord of firewood of various species, the first sorted by heat value, and the second sorted alphabetically for easy lookup.
The heat value measurement used is the British Thermal Unit, or BTU, which is defined as the amount of thermal energy it takes to raise one pound of water one degree F. One MBTU = one million BTUs. Weight and Heat content figures are based on seasoned wood at 20% moisture content, and 85 cu ft of wood per cord. To read about how we derived the numbers for our charts, click here. Regardless of what species of wood you burn, it won't produce optimal heat output and burn time unless it is properly seasoned. A Correction from Wyoming Just a comment on your BTU chart. Mike Hi Mike, I'll admit that a tight stack of dimensional lumber will have very little airspace, but dimensional lumber is sold by the board/foot, not the cord.
