So many times I’ve found myself in a meeting with an impossibly demanding architect who is essentially asking for a wireless light fixture.  Usually I break the stalemate by saying “I’ll just spec a wireless floating light bulb!”  I guess I’m in trouble now…Chris Rieger, an engineering student at Australia’s University of Queensland, has combined magnetic levitation with inductive wireless power transfer to demonstrate a floating light bulb.

I’m pretty sure the inherent power inefficiencies at the system level –not to mention the “oops!” moment during a power failure —  make this impractical for anything other then a novelty trick, but who knows…technology progresses fast.    Via Core77.
