We are already bringing the discharge steam down to condensate at about 28" Hg vacuum and at less than 100 degrees F to maximize the efficiency of the steam cycle. Now think. We immediately heat the water back up under pressure to about 450 degrees. Any energy you took out of that water. Any energy that we took out of this feedwater, would have to be added back as reheat.

"Projected spending . . . has declined by $31 billion for the 2007-2016 period," said the CBO report. "That reduction primarily reflects lower income-support payments to farmers for major crops because commodity prices are now expected to be higher than previously anticipated. In particular, CBO has reduced its estimates of support payments to corn producers as a result of stronger demand for ethanol." Corn prices have doubled since last fall and are the highest in a decade. Soybean and wheat prices rose as well, pulled up by corn.Ethanol didn't do anything of the kind, of course -- agricultural production costs rise and fall with petroleum prices.
