The problem of a Solar Tower is that the efficiency is low, though a very large collector area is needed to produce power; for instance a 1000 m high 200 MW tower requires an expensive 20 km² large green house, which causes the main part of the cost.
The problem of a Hurricane tower is that the height is small, so besides a pump a fan is needed to lift the air for the production of fresh water. If integrated in a solar tower no fan is needed and even power is generated, while both the Solar tower and the Hurricane tower can use the same tower.
