Can anyone explain to me why anyone would want flashlights in the handles of a jump rope? How many people need a flashlight for jumping rope? It seems to me the designers, Hyun Joo Lee and Eu Tteum Lee, have found an answer in search of a question. Their Jumping Light skipping rope generates power to run LED lights by harnessing the kinetic energy of jumping rope, and for the life of me I can't figure out why anyone would want to do such a thing.
I exercise a lot and regularly jump rope. Never have I found myself out in the dark, with my jump rope, in need of a light. And if I ever just needed a flashlight, I think it'd be annoying to have to deal with the ropes attached to the handles.
Just because you can add kinetic energy harvesting to something, doesn't mean you should. The Jumping Light makes even less sense than adding solar panels to your dog.
