One of the things that is needed in the middle east to help bring peace (other than land) is water. Out there, water is worth more than oil, gold or (in many cases) life. The problem of filtering water is an expensive one. If a way was found to cheaply convert sea water into drinking water, it would change things greatly. Here's the question. Is it possible to 'grow' carbon nano-tubes of a certain internal width? Can we build materials with 'holes' of a certian size? Think of this. A pipe takes water from the sea to a site a few miles inland. Every few feet there is a section of pipe that is made of a material that will hold all materials other than molecules of a certain size/shape. As water is pumped through, the salt content is forced through this material through pressure leaving water without salt. The gold is forced out at a different location (there's a certain amount of gold in all sea water). After a mile or so all you have flowing through this pipe is pure h2o or at least h2o with a few trace elements of rare minerals. Can we do this? Do we have the technology? We're building the parts for quantum computers. Can we build specific sized filtering materials? Does anyone know? There's actually a few other ways to do this including some that are biological in nature, but I just wanted to know what others know in the field. Do we have the tech? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Get the mailserver that powers this list at http://www.coolfusion.com
