re: How would this compare to asteroid mining?
Quote from Tom Brosz:
"A single half-mile diameter nickel-iron asteroid, assuming it assays out similarly to meteors of similar composition, would exceed the known world reserves for nickel, cobalt and platinum."
I wonder how this will be received by those who have shares in the companies that mine these minerals on Earth? Will this make them worthless once such resources are available? Will such people try to stop space mining as a result?
