What is the typical efficiency of a solenoid, neglecting friction? This would be a for a solenoid cycling very fast (with a spring or something to return it to the starting position). Or more importantly, what prevents a solenoid from being 100% efficient (neglecting friction)?. I've found...
I have invented (on paper) a limited slip differential that is completely geared and does not use any clutches, hydraulics, sensors, or electronics. It is simply a very unique arrangement of gears that has 1 input and 2 outputs. The outputs can spin at different speeds. As one output slows...
