A more sustainable Carnival

Fevereiro 10, 2012      by: Adriano Teixeira

Eletric Pee ProjectThis year’s Brazilian Carnival begins with a great innovation. It is the beginning of an ecological solution to a nasty but very common problem in Brazilian Carnivals: the pee in the streets. Every year many campaigns are made but the problem was never solved. Thinking about it,  now Afroreggae band and Rio de Janeiro city invented a sustainable destination to the pee. Well, it’s the first carnival float powered by urine.

How it works? See the picture. The mechanism is similar to a hydroelectric plant. First, the flow of urine is used as “a force to move the dynamo which uses fluid to generate power”. Second, it is stored in a battery that is connected to the carnival float after loading. Third, the energy is used. Therefore, if the pee is done in the correct place, the music festival is guaranteed.

Brilliant idea. Of course this is a practical example that people respond to incentives. In fact, behavior changes when new benefits appear. More information? Here are official information about the project. Here and here are other posters in English.
