Series 3. Eco Icon No.11

FloatingLightbulb‘ by Jeff Lieberman


What you are seeing is not an illusion, photoshop manipulation or illustration….it really is a floating wireless lightbulb.

Developed by MIT Robotics expert Jeff Lieberman  who also is a photographer, artist and inventor , his floating ‘lightbulb ‘ first wowed the  blogshere in 2005. Using the wireless power transfer technology invented by Nikola Tesla  in the late 1890’s he developed his first floating lightbulb, which “uses a special bulb, inside which magnets and circuitry are hidden. Using a magnetic hall effect sensor, an electromagnet, and a [modified] PD feedback system, it floats a lightbulb stably in the air, while power is transmitted wirelessly from the base of the sculpture into the bulb. LEDs in the bulb rectify this AC power and convert it to light.”

Now four years later it ha been upgraded .The new version “operates at much higher wireless transfer efficiency and  is brighter while consuming less energy and levitates at roughly 2.5” from the nearest object.

This light bulb  really is a levitating yet powered lightbulb. It will float stably in midair and remain on for years without any physical contact, charging, or batteries. Ironically, with the levitation and wireless power circuitry both on, this entire package still consumes less than half the power of an incandescent bulb.

This floating bulb is even more iconic and evocative because it fuses brilliant design with pioneering technology to produce a high impact, low consumption object that can be used daily…….certainly would light up my life….
