1) The minimum energy curve from ground to geosynchronous orbit is
not a straight line. 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.

The current situation, as near as I can make out, is that nanotube
technology is not quite strong enough, but it is close.

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.

This Clark space elevator concept has been discussed with the
sci.physics Aluminati who explained, let's get Uncle Al's parity
experiment funded and done first before we test stress the roll of tape
to the stars. 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.

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.

Nah, that's clearly ridiculous and fictional.

It's actually the antennalopes.

It beats them thar antenna deer. Walkin all over the country just
so some city slicker can make them annoying chripin sounds!
Can't even shoot 'em. Outta be a law again it.

Daymn. I wasn't paying close enough attention. I thought they were
deer.
