If you are interested in things that hover and fly, how about a levitating light bulb that can also power itself wirelessly? An electrical engineering student from the University of Queensland was able to develop a prototype of a levitating light bulb. Chris Rieger worked on the project for 6 months, combining previous researches conducted by other individuals. Rieger’s levitating light bulb is a combination of a magnetic wireless power transfer system and a magnetic levitating control system.
Rieger said that the most painful part of the project was the wireless power transfer functionality. He built an oscillator and a wireless power receiver circuit, which is a simple LC circuit tuned at exactly 1Mhz. Wireless power transfer is facilitated by a single large hoop of wire driven by alternating current at 1 MHz. This part of the system pulls 0.5A at 12V, bringing the whole of the consumption in at around 9 Watts. Then, a permanent magnet on the light assembly is used to levitate the light bulb.

These were designed by Devon Briggs, who probably got tired of having to ask for forks where there were none (or worse, eating using only his bare hands.) So what’s a lad to do? Come up with a way to bring forks wherever, so they can be used whenever you need them.
