There are many free energy from the air receivers that you can make on the Internet.
They will pull in about 2to 3 volts and current in the micro amp range. You need a long antenna wire and good ground to do this. I have made several myself.
Has anyone given thought as to how a tesla pancake coil can be employed within the receiver circuit
somehow and enhance the circuit so we see milliamps instead of micro amps of power??
I have myself made a receiver that produces 12 volts but the current is in the micro amp range which is useless.

Has anyone tried to do that? Hope to hear from you.
Are you sure that these receivers receive anything at all, or is the energy generated, like inside the sheet iron of the roof or something?
Good that you mentioned pancake. Pancake creates magnetic field perpendicular to it. But in addition the wire is in spiral, so i thought that it may work somewhat like a faraday's homopolar generator, or n-machine. Generating direct current, which should have no lenz effect. Amplifying current. One may test, discharge a capacitor through it and a big resistor, and then without pancake. If through pancake the capacitor discharges faster, then it amplifies current. That is, with the same discharging time, you can have a higher resistance load, and thus get more power. Just thoughts i had so far.
