The Green Picture: Glowing Array Of Fluorescent Bulbs Powered By Ambient Electricity

You know those electric fields from power lines that some people are always complaining about? Turn out they may have something be worried about. At least, that’s what I can surmise after viewing these photos of an art project on an English farm. The installation is called FIELD and creator Richard Box came up with the idea after hearing about a colleague playing light saber games with a fluorescent tube beneath power lines in his backyard. So, he bribed a local farmer to let him take a crack at installing 1301 fluorescent bulbs underneath his power lines and “voila” — instant ambient energy. The UK Guardian explains a bit more:

A fluorescent tube glows when an electrical voltage is set up across it. The electric field set up inside the tube excites atoms of mercury gas, making them emit ultraviolet light. This invisible light strikes the phosphor coating on the glass tube, mak ing it glow. Because powerlines are typically 400,000volts, and Earth is at an electrical potential of zero volts, pylons create electric fields between the cables they carry and the ground. Box denies that he aimed to draw attention to the potential dangers of powerlines. “For me, it was just the amazement of taking something that’s invisible and making it visible,” he says. “When it worked, I thought: ‘This is amazing.’”

My home is right under some power lines. Needless to say, I’m moving. <grin>
