From Earth, yep, probably so.
OTOH, from the Moon?
Turns out a lunar beanstalk could be built from the lunar surface to the Earth-Moon L1 or L2 LaGrange Points, using existing materials and technology. No magic carbon nanotubes needed. (-;
Because the Moon is tidally locked to the Earth, the Earth-Moon LaGrange Points are, conveniently, also “luna-synchronous.” Typically, the cable would run from near the lunar equator to the L1 or L2 point, but one could also be built very close to the poles.
The lunar poles have water, and peaks with “eternal sunlight” for constant high-intensity solar power.
The cable could also function as a supply pipe, exporting water (or hydrogen/oxygen produced from water) for use in deep space.
