Hi Bob,
In the TED video, Amory Lovins says that the process uses a kind of digital "inkjet printer", then thermo-form it into whatever complex shapes you want. The auro body can have say only 14 parts instead of 100-150 parts; each one is formed using one cheap die set, instead of four expensive ones for stamping steel. The carbon parts can be lifted w/o a hoist, and snapped together, and you can lay color in the mold and get rid of the paint shop, as well. You end up with a process that is ~2/5 the "capital intensity" as the most efficient steel plant. And the plant doesn't need to be a large.
