This bulb is in the air

 In the future, there will be no need to make holes in the walls where
 hide electrical son ceiling to illuminate our interior. The bulb
 the future will float in the air like that of Chris Rieger, an American student
 University of Queensland.
By combining wireless transfer of electricity and magnetic levitation ,
 this student was able to power a light bulb that levitates in the air.
 Today, the most successful project using magnetic levitation
 Maglev is a Japanese train that levitates above the rails.
 In his experience, Chris Rieger was able to send up to 12 volts
 the bulb. The energy transfer system wireless was hidden behind
 cartons boxes. After some improvements and numerous tests ,
 we can assume that this system can be installed inside walls
 a house. In case of power failure, do not panic, the bulb
 not collapse to the ground. It will bind directly to the metal wall
 hidden in the ceiling.
 Chris Rieger is now working on the possibility to adjust the height of the bulb. Although the technology of
 wireless transfer of energy is not new , experience in this kind may bring into our homes
 our cars and this type of power supply.
