Energy from Atmospheric pressure

Hello everyone, I have browsed an important list of patents relating to the production of energy from atmospheric pressure. It’s a challenge that I’ve been asking myself for more than three decades and I realized that the task in this area is not easy. I am developing a model that combines simplicity with practicality. Indeed it is first a question of producing compressed air first from the atmospheric pressure on a liquid, in order to use it to produce energy. The models I have found so far on the patents are very complex and I have yet to see one that actually works. If you have any simple model examples that work, please let me know.
Moreover, if you are interested, we can discuss more about the model that I developed and for which I am looking for support to develop it.
Cheers
