The merry go round/hard bar<br>swing would fit in this category.<br><br>So basically, let's look at activities where energy exerted is ambient<br>anyway? What I mean is that the energy is being used up by the kids<br>anyway, so why not tap into those. An example is to give them some<br>variant of those "dance straps" meant to power cellphones before they<br>go off to run and play during recess and lunch break.<br><br>One way to tap into this would be to create new playground<br>installation toys which can be used for harvesting energy.<br><br>Q: how much abuse can a kinetic energy harvester withstand? A soccer<br>of basketball has a lot of kinetic and impact energy bouncing around.<br>I'd imagine that's too much
abuse though, and whatever harvesting<br>mechanism would break from the forces.<br><br>Would piezo work there?</div><div><br></div><div>
