It doesn't look like it really does anything yet, but it is a neat concept. And you have to love the idea of a robot that poops.
IT EATS SHIT
IT'S A SHIT-EATING ROBOT
OH MY GOD, FUTURE, I LOVE YOU!
Look out Roomba. :lulz:
I love it! The fact that it's a robot that poops isn't even the coolest thing about it - it
eats sewage to power a
hydrogen fuel cell. It is a self-propelled artificial intestine.
QuoteDirector of Bristol Robotics Laboratory, Chris Melhuish, said microbial fuel cells had been tried before but an artificial gut was needed to solve the problem of previous models, which was that humans had to clean up the waste left by bacterial digestion. Melhuish said the robot was called Ecobot III, but admitted "diarrhea-bot would be more appropriate, as it's not exactly knocking out rabbit pellets."
