What Is The Crystal Radio Initiative?

What Is The Crystal Radio Initiative?


The Crystal Radio Initiative is an engineering challenge set by Eric Dollard on the Energetic Forum. The goal is to build a Tesla Resonant Transformer to receive the signal from a commercial AM radio station through the earth, and to perfect the receiver and grounding system to the point of drawing significant power. The challenge is to power a small incandescent light bulb, progressing up to 100 Watts!
