Current Topic:
How efficient is iron smelting ?
tell that to greenpeace. I'm sure they'll be plenty understanding....

My opinion, for what it is worth. I think we need to progress in baby steps. moon, then asteroids then mars. and consider the fact that the moon would make an excellent proving ground for mars expedition equipment and launching from there would not require NEARLY the energy that launching from earth would take (and nobody would complain about fallout there either!). and the moon is only three days away by existing technology. mars is over a year away using existing technology. makes solving problems a bit easier I'd say.

interesting trivia bit.

60% of all nickel ever mined on earth comes from one deposit in canada that is believed to be an ancient nickel-iron asteroid strike. Don't you know INCO would go nuts over access to another? and one in which the smelting could be done in situ?
