"OCEAN EXPLORERS AND entrepreneurs have been thinking about how to scoop up mineral-laden deposits on the seafloor since the HMS Challenger dragged a few up in a bucket during its globe-trotting scientific voyage in the 1870s. A century later, the CIA used deep sea mining as a cover story for a secretive plan to recover a sunken Russian nuclear sub.

Now, it's a serious engineering proposition. Companies in Belgium and the UK are testing crawlers and rovers to suck up potato-sized nodules on the seabed. And companies backed by Chinese, Japanese, and Korean governments are investigating the idea of drilling into the sides of underwater volcanoes or breaking off chunks of inactive hydrothermal vents—both places where minerals are deposited over time…"
