I understand where you come from with this idea, although the power that the gears with transfer will need grease, no matter what type of material you use. I know that carpet fibers and other junk gets stuck in normal grease, but you can also use dry grease. Machining tools (boring bars/milling disks) use dry grease so chips don't get stuck between important seals. I would look into using dry grease because of the low friction index, such as Dry Graphite Lube (I once used it to win a pine-wood derby).
