Not nearly. 2) Even if it were, allocating average 10 lbs/lineal foot is about a trillion grams lofted. It had better not cost $/gm material plus placement. 3) Name one equatorial nation that is politically stable. 4) Lightning. It rains a lot at the equator - like very afternoon. 5) Magnetosphere billowing. Electrically conductive cable is out of the question. "They also concentrated on the non-fixed tethers, which do not go all the way to the Earth's surface and consequently require mach 16 aircraft vehicles to reach them." The Mach 16 aircraft is not the hard part. When an MBA presents a business plan complete with estimated escalating profits using multiple technologies that do not yet exist, it is either cheap fraud or expensive NASA. -- Uncle Al http://www.mazepath.com/uncleal/ (Toxic URL!

The necessary strength/weight ratio has been demonstrated, but only for a single multicentimetre fiber without any safety factor, and the individual fibers are not strong enough to splice/form into a practical ~20 tonne 'seed' tether. On the other hand, the technology for hypersonic orbital tethers is probably more or less to hand; requiring only engineering and finance. Bob Clark |

3) Name one equatorial nation that is politically stable.
Ecuador? Brazil? Malaysia/Singapore? require mach 16 aircraft vehicles to reach them." The Mach 16 aircraft is not the hard part. Considering none has ever been built (the Shuttle is the only cargo-carrying machine that can go so fast, and it doesn't fly aerodynamically at that speed) I'd say it's a pretty "hard part." |

Estimated $50 billion US dollars for first proposed practical and cost saving viable nano tube roll is ok, but let Nasa intelligently allocate the petty cash to test equivalency principle to the bone. the nightbat |

It does fly aerodynamically.

Not nearly. 2) Even if it were, allocating average 10 lbs/lineal foot is about a trillion grams lofted. The only credible designs around right now allocate only a few kg per kilometer, rather less for the initial seed tether. It had better not cost $/gm material plus placement. Actually the plans assume that it is a few hundred or thousand dollars per gram. 3) Name one equatorial nation that is politically stable. It can be placed at sea; indeed that is the proposal. 4) Lightning. It rains a lot at the equator - like very afternoon. You probably should read the NIAC paper, they thought about that. 5) Magnetosphere billowing. Electrically conductive cable is out of the question. It's not going to be conductive unless they want it to be. |
