light bulb

light bulb - Not photoshopped or some magic trick. This is for real. Light bulb is a levitating yet powered lightbulb which floats in mid-air and remains on for years without any physical contact, charging or batteries. Coolest thing is that the levitation and wireless power consume less than half the power of an incandescent bulb (why are we still using it?!). The bulb and the casing contain hidden circuitry that uses electromagnetic feedback to levitate the bulb and uses coupled resonant wireless power transfer to beam power from the housing into the bulb itself. Awesome physics shit here and I think this should be further explored into commercial use. Check out the video below and click here for more info.
