The metal of all the salvage cars in the world are not recycled...You could make 2-4 stories apartment complexes with the metal of salvaged cars....melt it and mix it up with steel...And then YOU PUT A LINNING OF WOOD ON IT...It will be like putting wood floor on a house, except that is going all over, walls, ceiling, ect....

There is so much metals of salvage cars of all the cars in the world that i think it will cover an area of Greenland or bigger...

You DO KNOW THERE ARE BUILDINGS OF ONLY STEEL/METAL AND COST CHEAPER THAN A REGULAR CONCRETE BUILDING...

Question, when we travel to MARS and we dont find concrete in mars what you think is going to happen....
