I suppose we already are doing this with oil and natural gas. Gold is mined off of Alaska and Africa underwater. Undersea salvage has been going on for years especially after WWII. Very interesting that they can actually do this from the surface with large claws sort of like the coin operated machines in stores and restaurants. There was something in the news about this recently where they were salvaging sunken warships with no regard to the fact that these ships are now graves. Terrible, just terrible :evil:
I remember watching a documentary on that, fascinating indeed, like something out of a Clive Cussler novel.
