Floating light bulb

No, This isn't a trick or a photoshop manipulation. The lightbulb 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.

The lightbulb will float stably in midair and remain on for years without any physical contact, charging or batteries.
