"I bought little motors for my chickens with 60% efficiency. That is very high for such a small motor. They rotate very slowly, with butterfly force, with a large gear reduction. There is a commutator attached to it, just like on large motors. Five thin, gold pins bent around a small shaft that is then pulled out. And attached to that are two gold contacts: that gives you a 20% gain. For such a small chicken with thirty little motors turning, that is enormous. I used to have some with sound, but now you don't hear them. If you really want sound, you can recreate it with a small loudspeaker. Then everyone thinks it's those little motors." (July 11, 1989)
