Using Ocean Temperature Differences to Create Renewable Energy
2012-01-25 16:25:00 Ocean Thermal Energy Conversion (OTEC) is an idea for creating renewable energy by exploiting the difference in ocean temperatures between the surface and the seabed. The OTEC permit office first opened in 1981 as part of NOAA, America’s National Oceanic and Atmospheric Administration, the marine counterpart to NASA. It was created after the oil price spike of the 1970′s when interest in alternative power sources rose. Oil prices eventually settled and as a result interest in the alternative power sources dwindled, so in 1994, just 13 years later the OTEC office was closed without ever having issued a permit. Good old American bureaucracy. Now, again during times of high oil prices, alternative energy sources are back with vengeance.

Temperature of Compressed Air in Cylinder
2012-01-23 16:36:00 The formula PV = mRT is fine for general usage when it is assumed that ideal gas laws are obeyed where P and T are on the absolute scale, and that either one or other, pressure, mass, temperature or volume are known. But in practice compressed air obeys it's own set of gas laws that deviate from the

I used a RP1000 with a Hardwire Tube Overdrive in the Stomploop and a Egnator half stack and another Egnator combo for a powerslave. The guitar I used on that tour is my Tyler "Burning Water" Model.
