You’re driving along the highway and everything seems boring? Well, in this case, maybe the giant array of fluorescent lights that lit wirelessly from the electromagnetic fields of power lines will draw your attention here!
If you refer to the above figure, you’ll notice that the field was filled with 1,301 fluorescent lights. All the lights are powered by the electric fields, which is generated by overhead power lines.
Richard Box, the professor at Bristol University’s physic department, is the person who got the idea to play with the fluorescent lights under the pylons. In order to make his dream comes true; he decided to find a field, give a local farmer a total of £200 and planted 3,600 square meters with fluorescent lights directly in the middle of field!
Box said that a fluorescent light glows when an electrical voltage is set up across it. The fluorescent light can emit ultraviolet light itself, as the electric field set up inside the light excites atoms of mercury gas.
Since the power lines are normally 400,000 volts while Earth is always in zero volt, though the pylons can create electric fields between the cables they carry and the ground continuously!
