    okay heres my idea

    if you attach a diode to an antenna it is receiving radio waves/ac power and converts it to dc current
    now it is very small current, but wouldnt a transformer turn it into higher volts? with a combination of transistors, couldn't we use this energy?

    Also remember there is radio waves all around us, its a matter of converting it fast enough to power what ever.
    all my ideas come from trying to replicate teslas invention by the way.if you figure something out, please let me know.

    Upping the voltage does not up the power. It is the power that is important when trying to use the energy.

    On the other hand, look up "energy havesting." This is a technology for capturing small amounts of power and then using them in a burst infrequently. For instance, you might gather energy for 24 hours then use it all in a fraction of a second to transmit data from a sensor across a radio link.

    and further to what BobK said

    the signal strengths of those radio signals are absolutely tiny, just micro Volts (uV)
    and the transistors in your circuit, how do you plan to power them ??
    It wont be from the received signal .... not enough power for that

    thank you both!
