Free Energy/ Cellphone Detector (From Cellphone Antenna)

This simple circuit is able to detect signal from your cellphone antenna and converts it to electricity to power an LED ( the best thing about this is that its completely passive and doesn't require batteries ) this circuit requires: RF diode ( search ebay for: RF diode or microwave diode) LED Peace of wire Solder I have Noticed that it only detects phones working on (EDGE), ocasionally works on 3G I have a low knowledge about RF but I think it has to de with the shape and/or length of antennas. So if you can contribute to make it work better please do so. ( this is based on a video i saw a long time ago on you tube ) the video had no instructions. here is the link http://www.youtube.com/watch?v=CNJVhzOjWgU&playnext=1&list=PL8ACFDE47FA548451 (RF energy, LED, tesla, passive, electricity)

First Solder the led parallel to the Rf diode

Solder One peace of wire to each end of the RF diode which will work as antenna

The LED should Light up if the circuit is close enough to the phone while making a call.
I noticed that this works only if you are on EDGE .
If you are on 3G it only works occasionaly and the LED is very DIM
