Tribolectrics Your editor has long promoted the idea of the Grand Unified Airplane, a vehicle which would essentially power itself from sunlight, piezoelectrics, structural batteries, and even the friction of the air over its surfaces. He wrote about the concept in the May, 2013 Kitplanes, and has noted an increasing number of articles in scientific journals describing a variety of nanogenerators, including tribolectric types. Tribolectrics are not new, having been discovered in the 18th century and initially quantified by Johan Carl Wilcke, a Swedish Physicist in 1757. “Tribo” comes from the Greek for “rub,” and as shown in the following video, even the rubbing of air over a surface can generate electricity. Note that about the 1:25 point Dr. Wang blows across the nanogenerator and lights up the LEDs. Taking that idea and running with it, Warsaw-based designer Michal Bonikowski designed the Eather One to run on electricity generated during the airplane’s movement through the air. As exotic as it …
