This is a photograph of 1,301 florescent light tubes arrayed in a field beneath standard high power electrical lines. The energy causing them to glow is the magnetic field produced by those high power electrical lines.

No, it’s not there to demonstrate that the fields do in fact have real effects (despite what the government and electrical power lobby tells you). It’s a very interesting art project by artist Richard Box.

You can purchase a DVD of the entire project, or just peruse the gallery of photographs at Richard Box’s project page.
