One would think that a rotating dome home would face serious structural stability problems, but these remarkable structures are designed to be fully earthquake and hurricane resistant. The homes slowly rotate and use almost no energy in the process – in fact they gain energy that more than compensates for these shifts through solar power and in the moving process can provide more natural light to residents, which in turn reduces lighting needs. Originally built in France these homes are now available around the world – including in the United States. (Source)
