They made it at MIT but I have seen other versions prior to this. It's made for low-income areas and most of it is just an old bike and two drums, an inner perferrated drum that spins and an outer that sits still, holds water etc.
I bet you could make that into a pedal-powered chicken plucker instead of a whole, expensive, hard to move washing machine and bicycle your way to a cleaner chicken! XD
You would need to turn it up to make a chicken plucker
