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!
