I stumbled across these buildings in a Project Camelot Interview with George Green, where he introduces the idea of ever faster getting storms,that are generated by the HAARP Systems. And how to build houses in a relative cheap way that can withstand these storms,they intend to start upon us.
ca. min 9:00
He says they are built by pumping up a circular balloon,which is then layered with concrete and then there is a layer of foam for insulation purposes put on the inside of it. He mentions problems with the air exchange….I suppose they solved it by some sort of ventilators. A solution without any needs of electricity or power would be more preferable, since the purpose of these buildings is to make a survival possible in rough conditions,that include total collapse of the power fascilities/grids.
This way of building is indeed very cheap and I would like to know how it is done in detail.
