Space elevators - Building a permanent bridge for space exploration and economic development

Carbon Nanotubes and their Application in the Construction Industry

“…1 The first method to be discovered uses an electric arc-discharge, where a high voltage electrical current is passed through the air (or an inert or reactive gas) into a carbon electrode. The other methods are Proceedings of 1st International Symposium on Nanotechnology in Construction June [23][24][25]2003, Paisley, Scotland 3 laser ablation, using a high intensity laser beam directed at a carbon target, and chemical vapour deposition, which uses a carbon based gas such as methane at high temperatures and sometimes pressures. In all three cases free carbon atoms are obtained and given the energy necessary to form carbon nanotubes rather than graphite or amorphous carbon.…”

“…Carbon nanotubes have also been discussed as materials for the construction of very large, space based structures, including space elevators. 25 These cable systems have the theoretical capability of reaching from the earth's surface to far beyond geosynchronous orbit.…”

Optimal Solid Space Tower

“…Brief History. The idea of building a tower high above the Earth into the heavens is very old [1]. The writings of Moses, in chapter 11 of his book Genesis refers to an early civilization that tried to build a tower to heaven out of brick and tar.…”

Non-rocket Earth-Moon transport system

“…There are many articles that develop a tether method for a trajectory change of space vehicles areconnected by cable. Themainproblem withthis method is thatit requires energy for increasing the rotation ofthetether system (motorized tether [2] …”
