6/09/2015 — WI-FI (2.45GHz microwave frequency) now to be used to POWER DEVICES


 

Researchers have now “discovered” that WI-FI + Bluetooth (2.45GHz microwave frequency) can be used to power devices directly.

I was called a “conspiracy theorist” for saying this was possible for the past 4+ years, for saying WI-FI / Bluetooth (2.45GHz) microwaves could be used to power devices in your house.

We posted this video on how the process works, done by NASA in 1975.   The experiments were BURIED until we found them, and made them main stream knowledge!

Up until we put out the information, wireless power was being fully denied as a viable option for powering devices, some even going so far as to say 2.45GHz is “not microwave” frequency!

_______

How can microwaves be converted into DC electrical energy?

Simply put, you need a “rectenna” (rectifying antenna) to convert the microwave into DC energy — a simple diode + Low Pass Filter are what is required to “rectify” the 2.45GHz frequency into useable power.

Here is a video I made two months ago, showing this very same technology, and even talking about WI-FI being something that we can possibly use.

Maybe someone watched the video, and got inspiration, or maybe its just the biggest coincidence in the world:

After Stanford ripped my paper thin Carbon / Aluminum battery invention, I wouldn’t rule out the possibility that someone did indeed watch the video for their “inspiration”.

Ironically, last year (October 2014) I sent this “Wi-Fi” / wireless Microwave direct current power invention idea to Elon Musk as a power solution  for his DC powered electric cars.

Sent him a public tweet with the invention, and told him not only would it work on microwave frequency, but it will work on CELL PHONE frequency as well.

No response ever received, the tweet is still up by the way:

I foolishly thought Mr. Musk would respond, since they’re looking for a way to bring power to their electric cars via “charging stations”.  Why have a charging station, when your car can constantly charge when it is in the range of a cell phone tower or wifi transmitter (or under RADAR coverage for that matter)?

Anything putting out the 2GHz band can be converted into DC power using this method, thus a moving car should be in constant range of multiple signals in this 2GHz band.

The great thing about the rectenna, is that it does NOT interfere with any other transmissions, since it only converts what actually hits the antenna… the rectenna does not leech or “suck in” a signal like you might imagine….  for all the real nerds who will understand this… let me just say :  a rectenna is NOT a ‘joule thief‘.

The rectenna works just like a radio antenna on your car, or in your cell phone.  It only uses what it picks up directly.  The diode converts the AC power in the antenna, directly into DC power coming out of the “excited” diode.  The Low pass filter rectifies the power into useable current (lowers the Hz) after being transformed from AC to DC.

AC ϟ DC now applies in the 21st century to wireless power🙂

Finally, the rectenna does not BROADCAST anything, thus you’re not exposed to any frequencies yourself.  This whole system can work on current Wi-Fi and Cell phone tower coverage we already have.

It is good to see the new findings back up the already proved science.  This should finally shut up all the deniers who said wireless power using microwaves / wifi  was “impossible”.

Now , its not only proved “possible”, but is going to be put in the “internet of things” that needs small power input to operate.

Wi-Fi Signals Can Power Battery, Camera, Sensors [STUDY]

http://www.valuewalk.com/2015/06/wi-fi-power-battery-camera-sensors/

“Scientists deployed Wi-Fi signals to power a battery-free camera placed at a distance of five meters, a step that brings a more powerful Internet of Things (IoT) a step closer to reality.

According to the researchers, a Wi-Fi signal can be used to broadcast power to distant devices, which is called Power over Wi-Fi or PoWo-Fi.

Wi-Fi to facilitate IoT

the Internet of Things is the concept that every device could be equipped with a chip that broadcasts data such as its location or other parameters such as temperature or pressure. However, one challenge that engineers need to be figure out is how to connect the array of tiny machines without batteries in all of them. Vamsi Talla and colleagues at the University of Washington in Seattle might have a solution to this.

Wi-Fi radio broadcasts are basically a type of power signal picked up by the antenna. Wi-Fi receivers are made to collect the information that is carried by these broadcasts. Talla and his colleagues stated that this energy could be made use of many ways.

 

More on the the study

The researchers connected an antenna to a temperature sensor, placed it close to the Wi-Fi routers, and noted the resulting voltages in the device and for the length it can operate on this remote power source alone. Since Wi-Fi broadcasts are not consistent, variation in the signal varied the power for the sensor.

According to the MIT Technology Review, the scientists programmed the router to broadcast noise when it is not broadcasting information, and employed adjacent Wi-Fi channels to transmit, in order to prevent interference in data rates.

For the experiment, researchers used three AR9580 chipsets, standard electronics for Wi-Fi routers. The devices were programmed to broadcast to provide continuous power to an energy-harvesting sensor. After the experiments, the scientists measured the resulting voltages in their temperature sensor, and analyzed how long it can work at various distances from the modified router. The scientists noted that the temperature sensor could operate as far as six meters from the router, and by adding a rechargeable battery to the mix, the working range can be increased to about nine meters.

The researchers also attached a camera to the antenna that performed well in the tests. “The battery-free camera can operate up to [about five meters] from the router, with an image capture every 35 minutes,” researchers said.”
