Re: Window Motor vs. Fisher Price
By fitting the Barbie gearbox with some kind of power take-off ( example), it can be used to drive a winch, with plenty of power for an elevator.
As JVN and others have pointed out, by balancing an arm you can reduce the motor power requirements significantly, because the motor lifts only a gamepiece rather than the whole mechanism.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
