Negative air pressure generator

This is a mould, and, model to create negative air pressure; can be used in heating/cooling/power/water harvesting applications. Quite dependent on installation.

The (cement) mould itself is incomplete; needs you to insert a T pipe; but you can gather as much from looking at the full model.

Thank you Persia. This is inspired by bâdgir's. The air velocity should be quite a bit higher.
