Capturing energy as the guests walk over pressure bladders won't pay the wages here. If molecules push through flaps because they are there and going in the preferred direction and the event is not recorded in a high signal to noise memory the energy from returning the compressed molecues can run a turbine producing net energy.

It doesn't matter how you want to implement it. Whatever you do, there exists a microscopic description of it which also describes the noise. You can't use the noise as a ''black box'' in which you can hide entropy.
