Apparently, if you have enough oranges, you can power an electric billboard. This video, for a Tropicana promotion in France, details the creation of the outdoor sign, which took a ton of oranges and some technical know-how.
Creativity Online reports that 2,500 oranges were used and fitted with zinc and copper spikes, and “the orange juice dissolved the metals, causing their electrons to create a current.”
This, along with a recent Foursquare-enabled, dog food-dispensing billboard for GranataPet in Germany, shows that at least some out-of-the-box thinking related to outdoor advertising is happening in Europe.
