Space cars Starting with the very basics for mining and extracting, we can melt, mold, cast, assemble, and construct just about anything imagineable - including private, interconnectable, mobile, earth-independent space habitats. Only a few molds are needed - everything can be mass produced and assembled cheaply and quickly in space. The Space Car can be used for private transport and like lego blocks to creat larger space crafts and spin gravity systems.  I am thinking of affordability with a ceiling price of $100,000 for one that is propulsion ready and doing mass production of standard parts/hull cheaply in space. The first twenty or so space cars will be assembled in space from components made on earth and stacked inside the launch vehicle's cargo bay. Then we start making more of these space cars in space using asteroidal materials.
