In-the-air: Wirelessly powered levitating light bulb

lightbulb
It’s one of those magical kinda bulbs that rise up to mid air without the help of any wires. The levitating bulb is a powered light bulb that stays on like that in the same way without any physical contact, charging or batteries. The total power consumed by the bulb along with the levitation power is less than half the power consumed by the incandescent bulb. The bulb and the casing use electromagnetic technology to lift up the bulb to 2.5′ from the nearest object and to beam the power into the bulb the resonant wireless power system is used.
