Electricity-Producing Wheelchair

Designed by a group of South Korean designers that includes Min-Goo Kim, Yun-Jin Chang and Su-Eun Park, this smart self-powered wheelchair concept uses a generator powered by manual wheel motion to produce and store electricity. An electrical coil and magnets contained within the wheel hub generate electricity throughout the day, which is then stored and put to use to light the LED lights at night.  An LCD display shows how much power is left, though it’s awkwardly-placed on the outside of the hub. The purpose is to create a safer journey after the sun sets. [via The Design Blog]
