Tropicana Billboard powered by oranges

DDB Paris created a billboard that harnesses the energy from oranges to illuminate a neon sign that reads “Natural Energy” & the Tropicana logo.Through several thousand spikes of copper and zink, a lot of wiring and 3months of testing they managed to make a giant multi-cell battery powerful enough to light up a billboard. The custom build was produced by Unit9 in collaboration with director Johnny Hardstaff who created the accompanying 90 second film.
