Hey guys, I need to make an extremely powerful antenna that will pick up RF in the air or just to get ambient electricty.

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?

Really Powerful antenna

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

Looks like tommy wants to put up a big AM radio antenna in his back yard and power his house --

I suggest Tomy learn something about the electric field of the earth.

A "Field Mill" would make an awesome science fair project
