Cat Powered Humidifier and Air Purifier
A humidifier is a handy thing to have around, but just like every other appliance you own it sucks up the power. If you have a cat just lying around that needs some exercise you can take care of two issues at once. You can get your cat a little bit of a workout, all the while making it so that you don’t have to pay for your humidifier to get a bit of power.
The Wool Ball is a humidifier and air purifier that gets its juice from rolling about. Cats, kids, dogs and anyone else that likes rolling around the ball will be enough to keep it up and going. Of course should that lazy cat not be pulling his end of the weight for a day or two you can plug it into the wall as well. This is a design by Yuan Gu and so far it’s not quite up for sale just yet.
