A South Korean industrial designer has invented a ring-shaped treadmill that lets runners use their kinetic energy to wash clothes.
The concept treadmill by Si Hyeong Ryu has wash canisters inside that can be filled with dirty clothes, soap and water like any other washing machine.
The size and shape of the canisters reduces the need for a lot of water. When the jogger runs, the motion spins the canisters, agitating the laundry.
Extra power gets saved onto a battery as electricity to run the machine on days when the person is not jogging, 'Discovery News' reported.
A flexible display on the front of the wheel gives the runner a visual experience.
The treadmill, called The Wheel, is an entry for the 2014 Electrolux Design Lab competition, a global design competition that challenges artists and designers to rethink how people live and work.
