Can playground equipment be rigged up to generators/ dynamos to harvest energy that a school could then use?

Imagine a roundabout in a school playground that gets played on for about two hours a day. Underneath the centre could there be a dynamo gathering the electricity and storing it? It could be used to power night lights, or other temporary lighting (such as toilets, hallways etc). Dynamos could be attached to swings too. We could even design playground equipment for this purpose where children have to lift, pull, turn, spin, rotate objects or handles during play.

I'm calling it "Active Electricity". Cheesy tag line; "Harnessing the Energy of Youth"!

Is this a feasible idea? Does anyone want to help make it a reality? What challenges would there be to this being successful?

    Jan 23 2012: That is such a neat idea and I think it could be expanded to include anything that is moved by human power. Imagine shoes that used the pressure of the person's walk to generate power for their music device? Each time a cupboard or door is opened, or water runs through a faucet, it could generate a little bit of electricity. It's all just a question of efficiency of the system, which is a matter of time as research into the field gets more and more subtle. I can see all of this happening at some point.

      Jan 23 2012: I love the idea of electric shoes! Imagine putting the floor Xavier Belvemont mentions (comment below) into a shopping mall to make it self sufficient? Or outside a sports stadium to power the light? Or in the pedestrian tunnels on the underground (subway) to power the station lights? Or...
