The true believers of "self sustaining energy" will not be ushered away from their devotion to the "holy grail" by mere Scientific analysis. Science and logic be damned it's full speed ahead into the valley of doom. The only way they got their "wind and solar" systems is with government bailouts and taxpayer money. They still don't work but the mantra now is 'well we just don't have enough'. I'm not sure what is meant by a 'closed loop system'. If it's pumping water by solar and electric when there's no wind or sunlight in order to power hydroelectric power then better check the block diagram again because you're starting from nothing to achieve something with nothing to input.

Good article. The nature of man being what it is, I'm sure that someday there will be viable sources of energy but you still must pay the piper. You never get something for nothing.
