Jumping rope is a good workout that does nothing for the battery of your electronics, but that's all about to change with the PULSE Jump Rope. Designed by Uncharted Play, the same company that power-generating SOCCKET soccer ball, PULSE creates power through play. The power created is stored in a removable battery that can then be used to power or charge small electronic devices.
The idea behind the PULSE Jump Rope is that people in rural areas without access to reliable electricity can use it to power their electronics. The company is doing a limited beta run of 100 PULSEs, and each one is selling for $129. If the beta is successful then it's likely the price will drop steeply to make PULSE more appealing to consumers in third world countries.
