Wind Wall / Protection System

we propose "The Wind Wall" - a system which creates a wall by using wind power naturally produced with the arrival of each subway train. The wind will enter a draft which will emit compressed air to generate the effect of a natural and protective barrier. Furthermore, we can use this air to create a sound like a warning whistle to form another barrier.

"The Wind Wall" will induce an instinctual fear reaction in people, warning them to step back. With the use of natural wind energy, there is no pollution nor waste. This reusable energy makes "The Wind Wall" an efficient and environmentally friendly design.
