Magic or extreme science? Chris Rieger has built a “floating” LED light. The wireless light hovers in the air due to a series of magnets. Separate coils distribute power to the light, allowing for the owner to power it on and off with a switch. Although the light is less efficient than a regular LED light due to its ability to levitate, it still only uses 9 watts. The magnets allow the device to levitate because of their power-dependent electromagnetic field that actually makes the magnet embedded in the light repel the magnet in the ceiling. If the power goes out, the magnets will only stick together, making the light connect to the ceiling instead of crashing to the floor. The inventor says that if there is enough interest in this floating LED light, that he will produce kits for people to put together themselves in their own homes.
