I'm not exactly sure how a vacuum works. I understand that there are machines (motors?), as in a vacuum cleaner, that suck air. There are other vacuum designs though, if I am not mistaken. It is these that I am not sure about. So how do these work?
Hey guys!
I was just wondering if it is possible to create energy from compressing air? For example, a ziplock bag filled with air. If you sit on the bag, the air tries to escape. Is there any way to harness this energy? If so, would it be an efficient enough to be a practically applied system?
