Built like a tank.


Many years ago, I heard about one clever wind-energy-storage system ("Long-winded benefits," SN: 2/12/05, p. 110). A fellow in Pennsylvania purchased a surplus railroad tank car and buried it on his farm. A nearby windmill-powered compressor compressor, machine that decreases the volume of air or other gas by the application of pressure. Compressor types range from the simple hand pump and the piston-equipped compressor used to inflate tires to machines that use a rotating, bladed element to achieve  pumped air into the tank, which could store an enormous amount of compressed air compressed air, air whose volume has been decreased by the application of pressure. Air is compressed by various devices, including the simple hand pump and the reciprocating, rotary, centrifugal, and axial-flow compressors. . The fellow used it to power air tools in his carpenter shop. Smart fellow, that carpenter.
