Current Topic:
How efficient is iron smelting ?
Blueshift it was my concept to ship stuff home. my concept was smelting a nickel/iron asteroid in high earth orbit, or perhaps the moon for a bit of gravity to assist in the separation, for the nickel and dropping the raw cast nickel 200 billets back to the mojave for further refinement/alloying. or billets of incolloy and kovar class alloys (nickel iron alloys) could be refined in situ making them even more commercially valuble. launching them back to earth could be as simple as a linear motor/accellerator (remember, pure nickel is magnetic so it could be the armature of the motor all by itself. not so with incolloy however which is non-magnetic.) or as sophisiticated as a low moon orbit bolo launcher. His concept was to generate building materials for use in situ.
