Hello friends you hv also heard about tesla who was great inventor.i m going to make his device for collecting energy from air.for make this device you will need these things.... 1. 4 diodes 2. a 100uf ,50v capacitor 3. aluminum foil 4. piece of card board 5. some wires 6.LED(optional)
Get a piece of cardboard and take aluminum foil the size of ur cardboard and staple foil on cardboard then hang it in room or go outdoor and put it on a pole at least 9-10 feet off the ground.Now take a wire and connect its one end to anteena
Step 2: GROUNDING CONNECTION
its is easy to make if u can go outdoor then take a metal rod and take another wire and connect one end of wire to rod and stick rod in the ground.
Step 3: MAKING DEVICE
make circuit according to give figure.i make my circuit on bread board.You can use any type of capacitor as high uf you can,i used 100uf,50v capacitor.after completing your circuit as shown in figure get 1-2 volts in 10-15 min.i got 13.56 volts in 4 hours.my charging rate was very slow bcz i placed my antenna in my room only few centimeters above the ground.i am able to run a LED for 40-50 sec.
Step 4: THEORY OF OPERATION
as we know in normal days air content free positive charge and ground content negative charge.when we put antenna or any metallic object in air it gains positive polarity.in this project we are making aluminum foil positive and metal rod negative.when we connect a capacitor b\w them capacitor get charged.
