In a billboard for Tropicana orange juice, it is powered not using electricity, but thanks to thousands of oranges instead. The brainchild of advertising agency DDB, this particular billboard relies on the energy from a whole lot of oranges in order to power a neon sign.
Taking more than 3 months of testing before the project bore fruit, oranges aren’t the only ingredients used since several thousand spikes of copper and zinc were also thrown into the mix to make a giant mult-cell battery for the sign to be illuminated. Now this is what we call a refreshing ad!
