A rectenna is a circuit that produces a voltage by harvesting the energy from the electromagnetic fields around us trough an antenna.
My Designed Rectenna for GSM 900 signal harvesting via cell phone used lo glow a single Led (load)
this is a simple design to harvest the radient energy or also called as free energy. The electromagnetic waves are collected using a coil placed at a height from ground. the signals are then rectified using bridge rectifier and a capacitor is used to stor
heat (IR) rectennas convert heat photons directly into electricity. this electricity is in the trillions of cycles AC . The secondary electronics transform this energy down to more usable electric current. heat photons are everywhere on earth's surface 24
in this video i demonstrated how a microwave rectifying antenna works and also showed the processes used during the construction of the panel the dipole antenna has a length of 3 cm which corresponds to the wavelength of the microwaves and a width of 0.5

You can make these, easy! By soldering a bunch of "low forward voltage" diodes in series (the leads act as antennas) you can make large flat arrays of high gain? energy collectors that collect Microwave/RF/DTV/Radio signals and whatever else hits it!!! (c
Professor Wang leaves us some extraordinary new insights on how his cutting-edge technologies can change how we see energy production in the world. Dr. Z.L. Wang is the Hightower Chair in Materials Science and Engineering, and a Regent’s Professor at the
Energy harvesting time has come. Tiny devices that scavenge wasted energy could boost industry, improve its green credentials. Many industries including construction, transport, automotive, mobile communication, and sensors and instrumentation are already

Unlimited by the lifetime of a battery, this combat boot uses footsteps to power a GPS transmitter providing geographical coordinates over a cellular network. Optimally positioned lungs in the sole of the boot drive miniature turbines connected to generat
This video is about conversion of radio Frequency into electricity. It consist of small part of my work on the project deep Mine. If you want more videos in Future then just leave the comment in the comment section below.Reviews are welcome . :D
By combining our rectenna with the circuit from one of those solar garden lights (just replace the solar panel with the rectenna!), we can make a quick and easy RF (Radio Frequency) powered AA charger aka an "RF harvester"!!! AND MAYBE WE CAN DO MORE! ;)

This light makes 5Vdc off of an intermittent 12V pulse from a turn signal's flash.
The robot moves forward and stop when it encounter an obstacle. It waits until the rectenna receives RF energy from a source in order to move again. The red light in the right is powered on when the source is emitting RF signals.
