No posts for 48hrs, every thread goes zombie eventually.

A solar nano-nova is a much more interesting design problem than mere rising temperatures. The latest episode from Suspicious 0bservers is about wind. It divides the the globe into three [five?] zones because the change in angular momentum, if the crust decelerates, has more effect at the equator. For one value of un-survivable apocalypse the zones are — at least one 100mph wind at the poles, multiple 150-300mph winds at mid-latitudes and at least one 1000mph wind at the equator.

Surviving a 1000mph wind (with gravel) is a very tight design constraint, but 150-300mph winds sounds achievable. It would be a low-arched dome with a significant [ablative] ground cover and wedge-shaped berms occluding the entrance or windows. A detail cribbed from nuclear blast proof designs.
