Think about the number or libraries, underground stations, amusement parks, football stadiums and other places that use turnstiles as a way of regulating foot traffic. Now think about the amount of people that pass through such checkpoints. That’s a lot of feet.
A team of Chinese designers at Guangdong University of Technology have come up with a really simple and powerful idea: harness mechanical energy energy from turnstile movement and convert it to electric energy to power the facilities.
Along a similar premise is a new idea being trialled in Maryland, USA. The Colombia Athletic Club has fitted their workout bikes with generators which collect energy and store it for use by the club. People pedal-power the facility while working out. The gym is already seeing a return on the investment they spent installing the generator system.
Be it turnstiles in a library or bikes in a gym, inventions around generating energy from people and everyday activities are endless. If you’re feeling inspired, check out plenty more people powered ideas – or maybe even try and build one yourself.
