Under Space Tower the author understands structures having height from 100 km to the geosynchronous orbit and supported by Earth’s surface. The classical Space Elevator is not included in space towers. That has three main identifiers which distingue from Space Tower: Space Elevator has part over Geosynchronous Orbit (GSO) and all installation supported only the Earth’s centrifugal force, immobile cable connected to Earth’s surface, no pressure on Earth’s surface. A lot of new concepts, ideas and innovation in space towers were offered, developed and researched in last years especially after 2000. For example: optimal solid space towers, inflatable space towers (include optimal space tower), circle and centrifugal space towers, kinetic space towers, electrostatic space towers, electromagnetic space towers, and so on. Given review shortly summarizes there researches and gives a brief description them, note some their main advantages, shortcomings, defects and limitations. --------------- Key words: Space tower, optimal space mast, inflatable space tower, kinetic space tower, electrostatic space tower, magnetic space tower.
