Currently, i am thinking of what other possibilities that the Psi can do. One thought is using it to extend holding one's air capacity for a long time to survive poison, underwater and gases. Another one is to make like a energy door and walk in to the place you want to make it as a base some sort. I'm not sure how many Psi powers their are in the world as we speak, but they are tremendously Powerful. Another one can be like a person is able to see very clear at night, and see invisibile things. Flight could be also possible with Psi. I think Psi is like the Force , where like anything is possible with it. Duplicating objects and people for self defense and emergency replacements. I think their are so many possibilities that we have no idea what they are capable of doing.
