Crystal radio

“A crystal radio is a basic resonant circuit requiring only induction, capacitance and a radio “crystal,” a mineral semiconductor used to convert received radio signals into DC electrical signals that can be resolved with headphones as sound. These simple circuits require no batteries, tubes or transistors and operate with only the difference in voltage between the antenna and the ground.” (bacterial radio, http://prix2012.aec.at/prixwinner/7023/)
