In the most recent Smithsonian there is a photograph of a field in Bath, England. The unique subject of the photograph is a field of fluorescent tubes sunk into the ground underneath a large power line. There is enough energy in the air to light the tubes. The photograph is stunning. Unfortunately, I can’t find it on their online edition.
I did find the site of the guy who created the field of tubes. He really should get a copy of that photograph and post it on his site.
