Levitated lightbulb and wirelessly powered

Light bulb is a levitating yet powered lightbulb. It will float stably in midair and remain on for years without any physical contact, charging, or batteries. Ironically, with the levitation and wireless power circuitry both on, this entire package still consumes less than half the power of an incandescent bulb.

The bulb and the casing contain hidden circuitry that uses electromagnetic feedback to levitate the bulb roughly 2.5″ from the nearest object, and uses coupled resonant wireless power transfer to beam power from the housing into the bulb itself.

Tesla invented wireless power transfer in the late 1890’s. However this effect is still largely underutilized.
