It's a great idea.
But why not? Again, I'd guess cost. Not everyone can buy a house, and some people can't even choose where they live, really. I think, however, if you're going to live somewhere where tornados are prevalent, then you should consider a house like these. Plus, they just look awfully neat. Almost like living in a observatory. I think these will become more common, however.
I hope this helps!
I'm familiar with them
It does seem to make sense...the geodesic dome style buildings certainly offer less wind resistance..whether or not anything would have been able to stand up against the tornado in Greenburg, Kansas is questionable.
I love the construction techniques used in geodesics. If they were built with steel beams instead of wood framing, they probably would hold up better, too.
The ultimately safe home would be a geodesic dome built deep into a hillside with only the top of the dome at ground level...of course, the entire community of these geodesics would look like a landing strip for space ships <:O)
Interesting concept, though...
