Dear Mr. Pickens,
This message is the third a series of 6 messages on the energy sources that you enumerated on the You Tube video explaining "The Pickens Plan."
See hydroelectricity for extensive narrative on hydroElectric power which is one of the three energy sources enumerated in the PickensPlan employing free energy and as such does not consume any mass for the production of electric power. The Coefficient of Performance (COP) of the system is, therefore, infinite. The power produced from falling water, so in the final analysis the power source is gravity and is available 24/7 as long as there is water flowing in the stream, creek, or river. On a volume basis hydroelectric power is 7735 times more effective than wind because water is 7735 times denser than air (62.43 compared to 0.08071 pounds per cubic foot).
As an example, a 1.5 MW hydro electric plant might look like this (on my website, www.emref.net, there is code to allow the viewer to change the parameters):
