With energy costs not getting any cheaper, folks are always looking for ways to shave their electric bill and this concept dubbed the External Lighting might be something that would interest many folks. This light runs on energy that is generated during chores such as cleaning the floor. As you know, you use plenty of energy when you’re mopping the floor and this design aims to harness that energy and turn that friction into electricity, which will then be used to illuminate the house after the sun goes down. Aside from keeping your house clean and Mother Nature happy, the External Lighting will also make a nice decoration in your modern home.
