An interesting concept that an engineering student has come up with in university of Queensland, Australia. We all know that wireless power transfer is possible via magnetic induction over short distances. What this ingenious student has done is combine that with the ability of magnets to levitate. He has invented a levitating bulb that draw power wirelessly. See a video here... LevLight Project (Magnetic Levitation + Wireless Power Transfer)
Imagine a day when you just need to toss a bulb to your ceiling where it will draw power wirelessly and keep floating....Isn't it cool? and not to mention the umpteen places where you wished a light bulb to dispel darkness.
