  3. It might be a bit unclear from the picture regarding where to start, but usually with these things it's best to begin with the foundation. I'm not an expert on how to mix concrete but this might be a good start: http://en.wikipedia.org/wiki/Concrete

    In other words - the question is a little open-ended.
    "RF" is a very broad range and "pick up ambient electricity" is a bit vague.
    What do you hope to achieve?

    To start you off:

  5. Search for "energy harvesting antennas" and refine your questions.
