A/C clutch -- I thought that every car had a magnetic A/C clutch that disengaged when not in use. Therefore when you're not using the A/C you are only turning a pulley but not the entire compressor. I'm pretty sure that's how all the cars I have ever owned have worked.[/QUOTE]
I don't know about every car but my old 1981 Ford F250 work vehicle had one. I hardly consider it leading edge technology.
