From what the article says, it’s actually a pretty cool way of improving desalination plants. They use the left over brine, from desalination, that has a very high concentration of salt, and use it as the high salt concentration side, with regular seawater being used on the other side. This both gives them free energy and reduces the side effects of pumping that extremely salty water into the sea by diluting it.
For me, the best way I can describe what it feels like for me is: I can imagine an apple and I get a feeling as if I was seeing it, but I don’t actually see it. I don’t see an image in front of me. I only feel like I’m seeing an image, and I have to focus pretty hard to see anything in detail, but I can still use it to, for example, try and manipulate something in 3D, or try to remember what I was doing on a given day by trying to walk back through a place. I don’t know under what category that makes me fall under.
