Poo Power!

Have you ever wondered what else you could be recycling at home other than milk cartons and cereal packets? Well here’s an interesting but slightly smelly idea – poo powered robots! When bacteria breaks down microbes in any smelly household rubbish- sink sludge, dead flys or pet poo – electrically charged particles get left behind. Using a special membrance that looks like two back-to-back sheets of plastic, robot scientists can use these particles to power a robot. Here at the Festival of Science we have one called ‘EcoBot II’. So next time you clear up that stinky sludge just think about how useful it might be. One day you might even have a poop not petrol powered car!
