Leaving the physics out of this, I'm working on an idea for an in home MHD generator. I'm trying to figure out a conductive fluid to use. I'm back to the idea of salt water, or H20 + NaCl. I know this is a very conductive solution, but I'm no chemist. What I plan to do is put a MHD generator and use the water pipes leading into a home, to provide the flow of the fluid, since it's already a pressurized system with decent flow when anyone uses any water in the home.
I've read though that the basic result of adding NaCl to H2O is that it forms two ions, Na- and Cl+ along with H+ and OH-. Is this correct? What is one just adds Na or just Cl to water (H2O)? What is formed? One main concern is removing the additives from the water after it's passed through the generator, so how does one go about quickly, and effectively removing the Na and Cl from water? I know off reverse osmosis, electrodialysis, and ion exchange that do not involve boiling the water. Ion exchange seems like the best option. Electrodialysis would work but it's a very slow process it seems. I'm looking for something that can remove the sodium and chloride from the water and would not effect the pressure or speed of your basic shower head, or faucet. With an ion exchange though, seeing as both H+ and OH-, how does an ion exchange work to only change out the Na- and Cl+?
I am thinking that I could use two ion exchanges, one before the generator and one after the generator. The basic idea would be to replace any ions (fluoride, calcium, potassium) in the water with Na and Cl (salt) before the generator, then after the generator take the NaCl back out of the water and put the original ions in. Is this design feasible?
I previously had a partner working with me on this project and he was the chemistry guy but I've had to take over the whole thing for a while here, and I'm just not too well versed in chemicals/molecules and exactly how it all interacts.
Thanks
