Self-powered wheelchair produces electricity for night outings

Moving unaided on a wheelchair becomes a difficult task for the physically challenged, which becomes more risky during night. Adding mobility to the life of the disabled, a group of South Korean designers, including Min-Goo Kim, Yun-Jin Chang and Su-Eun Park, has come up with an innovative wheelchair that produces and accumulates electricity, as the disabled move it during the day, to light their way at night. This not only makes mobility safe for the users, but also produces green energy and supports a green lifestyle. Featuring LEDs that emit light during night, the wheelchair makes use of magnets that convert the wheel rotation into electricity in the electric plant, while the coil moves power through wires to the switch and LEDs. Moreover, users may check the gathered electricity on the LCD display located in the center of each wheel.
