A NY architectural firm has published its "speculative" plans for a skyhooked building hung from a captured asteroid:
They propose to build a tower 32 kilometers tall in Dubai, "which has proven to be a specialist in tall building construction at one fifth the cost of New York City construction", then hook it to an asteroid to be captured and put into LEO so that it goes into a sort of modified geosynch orbit that looks like an analemma (peaking over NY and offshore of Lima Peru), which is not coincidentally the name of the hypothetical building.
32 km of tower, assembled on a temporary foundation by the lowest bidder. That seems safe, right?
I see not a few issues with such a building (ignoring the challenges of catching and orbiting the rock in the first place, assembling 32 km of tower IN THE MIDDLE EAST and then attaching it to the asteroid AS IT WHIZZES BY.
I'd like to see the atmospheric drag estimates, the predicted wind loading in various (HURRICANE) weather conditions, the thermal expansion and contraction effects on the altitude of the bottom end AS IT PASSES OVER MOUNTAINS AND CITIES, and the required structural strength of the building itself since it has to survive being yanked off its temporary foundation when it's hooked up to the cable dangling from the passing asteroid.
Oh, and they forgot the counterweight ABOVE the asteroid.
Haven't we established that you build these things from the asteroid down, not from the ground up?
Damn architects who don't research prior art anyway.
