Tabletop Wireless Electric Power Demonstrator. Credit to circuit originator Marko Bakula of 4hv.org Concept is similar to MIT's recent work. Power electronic oscillator drives an Air-cored resonant transformer at approximately 1MHz. The load is a 12Vdc 1A brushless CPU fan and an orange LED. I have written a step-by-step design guide which both motivates a lot of the design choices and also explains in detail how the circuit works. This guide can be found online at: vtb.engr.sc.edu
