Saturday/ a levitating light bulb

Here is another picture from TIME, img_5690sm2one of its list of the 25 best inventions of 2016.   It’s a levitating LED light bulb.  And does it have a battery in the base? Nope.  There’s a wire for electricity that goes into the base, but then the light emitting diode (LED) is lit up by magnetic induction.  Such a special light bulb comes at a price of course: $359.  (But I want one).
