>> ...compressors are much cheaper than electric generators, these wind farms should cost less.
> I did not write the above. In fact I questioned it. Jones wrote it. Yup, I wrote it and stand by it. Here is an example. Maybe you can find a contrary one... (I'm sure you can, but it stands to reason that with the cost of copper being so much higher than iron, the comparison will favor the item NOT containing lots of copper.) 3 HP compressor Discount Price $199.99 http://www2.northerntool.com/cat-1/87+90145+2000008.htm 3 HP motor 1725 rpm, 230 Volts, 16 Amps, List $439 Discount $390 http://www.phaseconverter.com/ElectricMotor.html BTW DC generators generally cost more than AC motors, so instead of the difference being nearly a 2:1 spread it would likely be more. Jones BTW hydrogen electrolyzers are very expensive, so I do not think that there is much of a case for a favorable capital cost comparison vs. liquefaction. J.
