Inflatable Tower Could Climb To the Edge of Space

MonkeyClicker writes with mention of a proposal that could see an inflatable tower helping to carry people to the edge of space without the need for rocket propulsion. This would function in place of previous space elevator designs which featured a large cable and could be completed much faster, if proponents of the project are to be believed. "To stay upright and withstand winds, full-scale structures would require gyroscopes and active stabilization systems in each module. The team modeled a 15-kilometer tower made up of 100 modules, each one 150 meters tall and 230 meters in diameter, built from inflatable tubes 2 meters across. Quine estimates it would weigh about 800,000 tonnes when pressurized — around twice the weight of the world's largest supertanker."

      Eventually you get to the ridiculous point where your tower is >100 m wide because the atmosphere is so thin.

      You naysayers will be crying when I build my giant space marshmallow chain.

      100 m wide? I don't think so. The trick is to fill them with your lighter-than-air mixture at the local atmospheric density... create, heat, inflate, rigidify, cool. And 100 m is just about right, from the base all the way up.

      When it gets too high, then you simply start at your Chambered Heuristic Orbital Clasp Object -- Ladder Attachment Terminal Endpoint, and work your way back down.

      The big problem I see is the earthbound anchor, but I believe professor William T. Graham (a pasty-white fellow my less couth colleagues refer to as a 'cracker') is working on a solution to that.

      All of humanity shall be as neanderthals around the campfire, envying the colossal testament to my intellectual superiority. Plus, they'll probably have a hankering for S'mores, what with the figurative campfire and all.

      How long have you been waiting to use that? An entire post about graham crackers?

      Well, the idea came naturally to me when I started to respond to the prior poster about the column needing to be very wide as the atmosphere got less dense. And then I got to thinking about how marshmallows get their lightness, and I thought maybe it would be applicable to the problem at hand.

      And then I realized I hadn't had dinner yet, and that I'd better call my wife on my way home and ask her to start the charcoal for the grill. And then I started thinking about s'moresr,because it's summer, and I'll be grilling over charcoal tonight, and I just couldn't help myself.

      Sometimes the muse takes over and we just sit, trancelike, while the genius flows from our fingertips to the keyboard. I don't think that really was me typing, nor was it my idea... it was like some force greater than man itself took ahold of me -- just used me as a conduit for brilliance. Kind of like Noah's ark, I guess... it is not my place to question why. It is only my place to build it, as directed by what can only be the divine inspiration of He of the Tangled Forkful, the FSM.

      But seriously, if you think that was thought up ahead of time, and I'd been waiting to use... don;t you think it'd be a little more polished?

    you do know the reason why "hot air floats" do you? it's because it expands, and therefore has lower density. So in order to make a 'concrete balloon', your concrete sphere has to be elastic enough to expand when you heat it. concrete is not really that flexible.
