One other thought here (and I'm not sure how "good" it is for the motors and
I know that efficiency is not the best) is that you will note if you connect
two motors together with the typical electrical connection wire (with no RCX
in the system) that if you twist the shaft of one motor, it will act just
like a generator and will make the second motor turn. I've been thinking
about how to use this to somehow GENERATE alternative "power" for my RCX
controlled legos and have a motor provide all the current. Say a windmill
or water wheel or spring or something. Anyone done something like this?
