And upside down in earthquake zones so they just rock and roll with shifting
earth and if left off-kilter after the earthquake event can have an edge
picked up with a light crane and mudjacked back to level.
Then in a hundred years architects will say "hey it looks like a flying
saucer with curved foundations and a curved habitat on top. Why don't we put
a nano-gravity generator on it and see if it will fly?" But since they are a
bunch of stinking licensed facist rats they won't let anybody do this
without their permission.

>>I remember seeing a program (I think it was on the discovery channel) a

>>and rebar. As far as I can recall this dome started off with a layer of
>>rebar somewhat laid down across its center (imagine: draw a circle, then
>>put lines across the circumference creating almost a pie chart look- I'm
>>sure there is more to it) and then they add cement to top it off. They
>>let this layer dry thoroughly. They then added a big balloon (I don't
>>recall the material used) across the entire foundation. The next part I
>>am still a bit foggy about, but what they did was laid cement down over
>>top of the balloon (or maybe it was more rebar and cement...) then they
>>quickly topped it off with a layer of cheese cloth. Next they sprayed the
>>cheese cloth with water to keep the cement from cracking as they filled
>>the balloon with air... I recall them saying the pressure used was
>>equivalent to the puff off a cigarette because the balloon covered such a
>>large surface area of the cement. I don't remember exactly how long it
>>took for them to blow it up, but I think it was like, 4-8 hours, maybe
>>12... then they left it to dry and it was finished within a couple of
>>days. They showed other versions of this with intersecting domes that
>>were massive, some 80+ feet tall... Again my memory is a big blurry over
>>this so I may have left some steps out on building this. Ingenious, super
>>efficient, materials are available almost everywhere and it is extremely
>>cheap, only a couple thousand dollars for materials. If anyone knows the
>>name of the inventor or a website or some way of contacting him I would be
>>very interested if you could help me find out! My em@il is:
