Abstract: The improved liquid transportation and desalination system transports seawater or other saline liquids through a piped distribution system with essentially no moving parts by relying on MHD principles. A fluid pump device comprised of high-strength permanent magnets forming chambers through which the liquid passes and inter-chamber opposing electrode plates with an applied DC potential provide the magnetic flux density and electric current for generating the Lorentz forces acting on the liquid. The fluid pump device may be combined with a desalination filtration device for provision of fresh water near the end of the distribution line without the need for a largescale treatment plant. Desalination/filtration occurs through use of nano-porous graphene and/or carbon nanotube media.
