Simple Circuits to Collect Free Energy from Atmosphere

Last updated on 13 June 2026 by Admin-Lavi Leave a Comment

Looks like devices make sound with no power; but not true, power come from radio transmitter close by. Radio send waves and device catch waves and use for power. So device do not make sound by itself; but it gets energy from outside. Example: crystal radio in circuit below. COP show how much output power […]
