Why not look at it like a nuclear power plant and build a similar solution? You can reject gigawatts of power with one wet cooling tower. If pumping water up and down that distance is infeasible, then make the primary coolant loop use a phase change refrigerant. Much easier to pump long vertical distances. Condensed fluid would flow down with gravity, evaporated gas would flow up.
