i need to brake this into at least 5 topics
1) astroid proccessing 2) aquire and transport 3) sales and manufacturing 4) personel and emplyment 5) other subjects
1) parabolic reflectors aimed at the sun would not have to be very large to melt pretty much any rock found in space...
give me a parabloic reflector 500 meters in diameter with a gyro metric guidance system and the big problem is collecting the liquid metal in a centrafuge and spinning out the iron and silicone ... frankly , taking it to the moon after primary refinement sems more likly... zero gravity makes things hard to controll .
toroidal magnets made of glass tubing with yttrium , copper , carbon and oxygen film coated on the inside surface.... then etched so you have a thin electromagnet super conductor ring , 2 kilometers in diameter which makes a feild that effects the stream of particals of the solar wind that have a ion charge ( about 20% ) would use the " mary poppins " lifter to get out from the earths orbit... once you have attached a line onto a astroid ... aim the same 3 or 4 toroidal super conductor magnets at the largest magnet in the sky.... ( the sun ) ... and suck your way back to earth useing the very same solar wind as your propellant ( and a magnetic feild as the drive )
3) frankly , the goverment is not the greatest deep pocket... they change the rules like a traffic light ( green one second and red the next ) ... far better is to use the construction materials in orbit to build stuff... and build gold and silver , platnium and rare earth materials into re-entry vehicals... that you very carefully snag... and sell when its on the ground ...
at 10,oo.oo a pound to get stuff into orbit , it pays for it self to keep stuff in orbit ... the first service bays that need to be put in place are strip shops , that take pirated satilights and turns them into spare parts for other satilights ..... repare shops , and storage bays .... manufacturing and machine shops can come later... cattle drives , collecting and recycling old satilights seems the first profitable enterprises
4) getting people to fly in space is not high on the list of things to do.... building telepresents communications centers with people on the ground who can operate space craft like a remote controlled air plane or a model car on a 24 / 7 / 365 is first thing on the runway .. you need craft in space , and you need people on the ground driving it .
