I've been lurking here for a little while, but just registered and this is my first post.

Alternators don't operate like A/C compressors do. An A/C compressor has a clutch bearing, which when disengaged (no A/C) spins freely without resistance...that being said, removing the accessory belt on engines where the water pump is not a crank-driven accessory is somewhat common in drag racing for that very reason; less resistance on the engine.

If you so desire to bypass the alternator for brief periods, keep in mind its the alternators job to maintain current charge in the battery while powering the vehicle's electrical system; taking it out of the equation leaves the battery, and any fuel savings you may experience may be trumped by a much shorter battery life.
