Turnstile Power

We pass through rotating gates at many checkpoints like train stations and amusement parks and we never give it a thought but there is a lot of potential mechanical energy that can be harnessed. The Green Pass is one such gate with a three-roller switch mechanism to trap, transfer and convert mechanical energy as you pass through its turnstiles.

Green Pass is a 2010 Liteon Awards winning project.

Designers: Bi Zhao, Fengchi L, Meixian Su, Fengming Chen, Yuke Li, Jiamin Liang & Yujie Chen

    Hello,
    Excelent device. I manage a company that might be interested in it.
    How can we establish contact with the developers?

    First power generation concept posted here in awhile that is actually plausible. Turnstiles don't use much power to begin with – this design passes the engineering gut check if it's intended to power itself.

    That said, the gearing mechanism shown is a fairly expensive/low reliability/loud method of implementation (a gear head motor might be better suited).

    Lastly, a many of municipalities are switching away from turnstiles as they reduce throughput compared to a gate (for entrance control) or optical sensor (if you have a line of people leaving, the gate remains open allowing people to exist faster).
