Levitating Lightbulb.

'This kinetic sculpture by Jeff Lieberman featured at this year's Sonar festival in Barcelona, and its creator proudly admits it is directly inspired by the thinking of FT's favourite neglected genius Nikolai Tesla. The bulb is levitated by electromagnetic feedback, and uses wireless power transfer to light itself up. Amazingly this set up uses less than half the power than a directly powered bulb.'

If you would like to continue to joke about my "hetero-man-crush" on Nikola Tesla, think about this, first.
