This 3C Rope Skipping concept seems to be a similar concept to the Jump Light that we mentioned to you a few days ago, but instead of powering a flash light, it’ll allow you to recharge your rechargeable batteries when you use the jump rope. That power can also be used to show the amount of complete rotations, the potential amount of calories you’ve burned, and also a stop watch, all thanks to the display on the handle of the rope. It’s good to see people trying to harness all this energy that we expend when we’re exercising.
