Green Pass Turnstile

They say that small things make a better life. Green Pass turnstile is a simple idea, a concept that turns mechanical energy to electric one. Turnstiles are located in various public locations and by using mechanical energy it supports it's own consumption, the goal being zero pollution an zero discharge product. The movement of the wheel transmits power to a generator, which later is used to operate the Green Pass turnstile itself.
