We had a neighbor that put loops of wire under a 600kV line and got enough power to run a water pump for cows. The square law makes that kind of thing pretty low-return.

The Mythbusters also tried it in the "Free Energy" episode. They pretty much said extracting any useful amount of energy is not worth the effort.
Here's some calculations on the return [0] (usual caveats of stuff found on the internet). Quite low returns indeed!
