Extention Cords

I finally recieved a pair of »www.thinkgeek.com/stuff/41/wec.shtml?cpg=28H and they work awsome. Has anyone tried them yet? I have them transmitting from a pop to a pop without power about 6 miles away. I ripped off the stupid looking antennas and replaced them with pigtails and 24dbi grids.

I also used them, after Joe told me about it, and I have to say, this is REALLY cool. It's a LOT cheaper than solar panels and marine batteries, and a lot easier to use. The 7.2Ghz grids are so small that they almost fit anywhere.

I just about pee'd my pants reading this....

I'm going to attach one to my wife's vacuum cleaner with a 7dB duck antenna and watch her go to town. I wonder if you can create a mesh and just purchase the female ends

7.2Ghz generates extreme voltage when it is subject to inverse polarities. If You use it to generate heat, it will easily power a DC to AC rectifier, and the heat exchange will make 120V AC without a problem. Since the wavelength is so short, swapping out the polarities causes the modulation to cause extreme heat, driving the receiving chip to oscillate. the oscillations correspond to the same wavelength as 120V, so You can use this anywhere. MIT grads came up with this last year, BUT it took quite awhile to contain the extreme heat. This is the greatest.

that was a good one. if my history is correct someone has already done that, long time ago.

Future is bright for small-scale wireless power delivery.

1. Yagi used his namesake antenna in the late 1920s in several "wireless power" experiments. He failed.

2. Tiny model helicopters have been powered using microwave rectifying antenna (rectenna) devices.

3. Lightwave powered rectenna devices is the subject of serious US Govt research.

If I recall Tesla was also working on wireless power applications. He thought it would be possible to power a flying airplane from a base on the ground.

When asked if it would mess the current economy since oil was such a big part of it he replied "I think it's pretty messed up already!"

And this was like 1930 and here we are with oil still being the biggest business in the country.

Didn't Tesla try wireless power? Yeah, it worked, but it was a hair raising experience.

This April fools post actually has been very very inspiring.

I am thinking that a 2W access point could be powered using available 77Ghz automotive radar modules with a more focused horn antenna.

I also found US and Israel has riot control weapons that use microwave beams. I am sure a few watts reach the skin at 100 meters.

when i started my wisp business i had a couple of retired RF engineers help me do some link budgets and such on my first major pop. May both rest in peace. We got to talking about microwave rf and what it could do, one of the old men laughed to himself and said i'll sent you a link to something you might want to keep up with as time goes on. he did and i have.

I heard that people, who lived near very high power radio stations, have been able to pick up the rf energy to light their flourescent light bulbs in their homes.

I heard this years ago. I don't know where it was done at. I know there use to be some pretty high power AM radio stations around.

Several years ago there was a very high power one, I think in the mid west...I forget the call letters. They lowered their power after years of high power operation...I think to save electricity...lol.

I don't remember the call letters right now, but at their high power, I bet if you lived near them, you could put up some kind of long wire antenna to pick up the eneregy and light some flourescent light bulbs.

i don't know about am but fm will. i have a pop at a fm station and had some equipment in the transmitter building. one day i forgot to check something and went back in the building after just leaving and turning off the lights. but when i opened the door the floresant lights directly above the tuning tube of the fm transmitter were lit up about a foot wide. after a while they finally went out. i moved my stuff out of the room and mounted a box on the side of the building to house my stuff.

Yep - Tesla coils have been known to light up flourecent bulbs from several yards away. A google search yields some pretty cool videos!

I have lit many a flourescent bulbs under Hydro transmission lines. But Richard Box has made a prank into an artform. »www.richardbox.com/

Dr. Schute, a favourite prof at the U of A, did this trick at our first-year Electromagnetics class. He asked the only female student in our class to come to the front and take one 4ft bulb out of a package that had 2 bulbs.

She was holding it beside his desk when suddenly it lit up and the whole class gasped. She dropped the bulb and it shattered. He then repeated the experiment with the second bulb and explained how it worked.

[Edit] I was reminded that overhead power lines carrying 400kV creates a significant electrical field to the ground. This field creates the same effect as the ballast used to drive these flouroscent bulbs. There is no RF involved at all and these fields are harmless.

I was also told that a model airplane flew using only microwave power delivery right here in Ottawa at the CRC grounds.

500kW EIRP at 5Ghz was used.
