Designers Feijun Chen and Bin Zhao must have had enough of stubbing their toes against furniture during the night when making their way to the loo in order to take a leak, hence the Shoe Headlights concept that does not need any batteries to run. In fact, it draws power from kinetic energy converted into electrical energy, which is all good but how many people actually take the trouble to walk around the house over and over again in order to garner enough power in the first place? Apparently, the headlights will be able to keep on shining for 12 hours straight with a maximum dispersal range of 1.5 meters. Sounds super efficient, but hey - concepts are always there for you to go wild, right?
