Normally, the sun heats the earth during the day, and most of this heat energy is radiated off at night, so that the daily effect of the sun does not heat the earth, on the average. When this balance is upset, we have global warming or cooling. As is pointed out in this article, the amount of energy involved each day is huge compared to the amount we can change by things we do in the short term.
However, if we start capturing massive extra amounts of energy, as will this plan, and using it (read: converting it to waste heat), we may well cause global warming even if we somewhat reduce greenhouse gasses. I didn't see this problem discussed.
Basically, you can't get something for nothing.
Any Ideas?
