      I kind of want a poster that says "When life gives you 1232 lemons, you make lemonade, and then force kids to drink it to power your regenerative zipline" it's just the sort of out-there, oddly specific thing I love XD

      @Some Otherworldly Being Yes, there is no such thing as a failed experiment. Also a 48 kWh trolley going 2 mph would need only around 50W, so it has a range of 2000 miles! With 150W solar, it could drive continiously circling the earth every year and a half. Far better than any Mars rover.

      @Bavarian Hobbit How this fails is that the weight (In this case it was children) was removed when lifting the zipline back up which is what generated energy, the difference in weight meant that when going down there was more KE because more mass but when going up and using up that energy generated the children/weight was not there so you still kept the energy generated by the weight of the kid on the line. You would lose energy if the children stayed on the zipline when its recalled to the top.

      USAGI - And someone who can actually explain it to children as well.
