Radio-frequency Harvesting

    Radio-frequency Harvesting

    THE INDUCTION SYSTEMS are only the beginning. Some of the most visually arresting examples of wireless electricity are based on what's known as radio frequency, or RF. While less efficient, they work across distances of up to 85 feet. In these systems, electricity is transformed into radio waves, which are transmitted across a room, then received by so-called power harvesters and translated back into low-voltage direct current


    I found this on the web and i really want to know how this works, could anyone explain to me how i could build this?
