When reporting on the BunBun human-powered flashlight back in March, Gizmag's Rick Martin mused on the potential for putting a similar charging mechanism into skipping rope handles... which is just what Kyung Guk Lee has done with this design concept. The e-rope lets you recharge your AA batteries while you skip your way to better health.
Using kinetic power to charge batteries is not a new idea, but this design certainly does it in style. LED lights on the side of the handle would indicate when the battery is empty, half-way to being fully powered, or fully-charged. The silicone handles make it comfortable to hold and are marked with +/- indicators so you know which way to put in the battery. The aim is to provide enough energy to charge one AA battery after 20 minutes of jumping with the device taking up to four batteries at once.
