A crystal set is the simplest form of radio. It needs no batteries or other power source apart from the energy provided by the radio waves it receives. Modern crystal sets use a germanium diode to recover the audio from the radio signal but the earliest (pre-war) examples used a crystal of galena, hence the name. See How Radios Work in the Wiki.
