It sounds like a scam to me. "elevation difference of 3,700 feet, separated by 105 miles, they found the pressure difference to be in the range of 0.5 to 0.7 psi (pounds per square inch) on a daily basis, never going below 0.5 psi You'd expect more than 0.5 PSI pressure difference due to the weight of the 3,700 foot tall air column. Air pressure decreases with altitude. There is no energy to be gained there. That, and the fact that a 0.5 PSI pressure drop across a few hundred miles isn't even enough to generate high wind speeds in the open atmosphere. It would never be able to do it in a confined pipe. Someone can calculate it if they want, but I wouldn't bother with these guys. -g
