With the use of both of these principles combined no pumps are needed since the water will flow up the tunnel naturally. They can also be placed in the Yucatan and Caribbean currents thus cooling the Gulf of Mexico via the loop current thus saving the Gulf States, if placed SW of Key West They will save the whole East coast Of North America. The ssts can be regulated to 70 to 75 degrees by the addition of a gate on the discharge end of the tunnel that regulates the flow of cool water flowing from them. Also, these tunnels will generate enough electricity for millions of people from the flow of water coming from them.
