In recent years, a number of mega-cities have provided 3D photorealistic virtual models to support the decisions making process for maintaining the cities' infrastructure and environment more effectively. 3D virtual city ...
Feasibility of 20 km free-standing inflatable space tower

Seth, R.K.; Quine, B.M.; Zhu, Z.H. (British Interplanetary Society, May-10)

This paper describes the theory and analysis for the construction of a thin walled inflatable space tower of 20 km vertical extent in an equatorial location on Earth using gas pressure. The suborbital tower of 20 km height ...
A free-standing space elevator structure: a practical alternative to the space tether

Quine, B. M.; Seth, R. K.; Zhu, Z. H. (Elsevier, 2009-04-19)

Space tethers have been investigated widely as a means to provide easy access to space. However, the design and construction of such a device presents significant unsolved technological challenges. We propose an alternative ...
