I have been thinking about this idea for some time now. While visiting a park and watching my kids rides the swing and as I observed, power is generated and accelerated by the ride (very obvious :) - swinging back and forth) provided that the person who rides it, pushed and jerks his feet upon reaching the crescendo on the back swing.
I tried it myself and I can swing faster without touching the ground, without external force or interference only by the timely and synchronized movement of my feet.
I wonder if a robot can simulate this swing formula. Let's say 10+ robots in parallel succession, I believed it can generate enough power to light a modern house. Thus saves fuel, most of all it's green and eco friendly.
A wild but interesting idea I guess.
