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.
