Nikola Tesla Secret is something new that promises to reveal to you how to make a product to be able to collect 100 % free electrical power from radio waves and also the environment. http://netzeroguide.com/tesla-secret.html

Radio is the wireless transmission of signals through free space by electromagnetic radiation. Information, such as sound, is carried by systematically changing (modulating) some property of the radiated waves, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form. (from…
