Richard Box, artist-in-residence at Bristol University’s physics department got the idea for this installation from a friend. Talking about how florescent bulbs light up beneath power lines that got Box thinking.
After ‘bribing’ a farmer £200 to use his field he used 1031 florescent tubes ‘planted’ across the site at the foot of an electricity pylon. Towards the evening they pick up the waste emission from the overhead power line causing them to light up as they would inside a normal fixture.
