Thanks for letting me know, I never heard of that. I just know that alternators are generally only about 50% efficient. Do you have a link to any information on that?

Unplugging one of the fans wouldn't work, I live in the south and we see 100+ degree days here. The engine cools fine with 1 fan, but the AC doesn't work well at idle and low speeds with only half of the condenser getting cooled off and the compressor drags the idle down noticeably more than with 2 fans. The extra power the compressor draws from the higher head pressure would almost certainly outweigh any efficiency benefit from the power savings as the compressor uses much more power than the fans.
