There are further many other considerations in design for a 1km high structure. Ground stability and uneven sag under its own dead load as well as seismic events, harmonics and sway in the structure with wind or even rain strike. Some such structures have responsive hydraulic rams in the sub-basement to pump in dynamic loads to control the total sway to avoid resonant self destruction, and to hold the structure stable enough so that fixtures like the generators in the flue don't tear themselves out of their mountings. The prototype in Spain is 'only' 200m high, to prove the passive function. Kym Stanley Robinson anticipates stationary Earth orbit to equator elevators on the same principle for when we get serious about such structures. I personally look forward to the guaranteed thermal and Cu on track heading east-west cross country. _______________________________________________ Aus-soaring mailing list [EMAIL PROTECTED] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
