We have seen it before (previous post: Human Powered Ferris Wheel), but it never gets any less amazing. Talk about resourcefulness. No need for electricity. Use humans to power your ferris wheel (if you had one sitting around... I wish I had one).
"At the Hindu Swasthani Mela festival held in Kathmandu earlier this month, I spotted a small ferris wheel that appeared to be non-functional. It consisted of four octagonal open-air cages and a simple metal frame. When two kids climbed into one of the octagons, though, a man got up on the other side and started jumping up and down, eventually getting the thing to turn like any other ferris wheel.
Apparently this is pretty common in parts of Asia where electricity is not always readily available...The merry-go-round you see in the right corner of the above video, by the way, was powered by a used car battery."
