Space mining start-up Planetary Resources President, Chris Lewicki, made more than one eyebrow rise Wednesday as he wrote in his blog that about $16 trillion of platinum is waiting to be extracted from our Earth's oceans.

However, he also said that mining asteroids is a cheaper and more realistic option.

It would "only" take 7 million years to work through all the water on Earth, says Lewicki, who bills himself as "chief asteroid miner."

He multiplied the approximate concentration of platinum in seawater, about 2.34E-10 grams per liter, by the amount of water in the ocean—1.3E21 liters—and came to the conclusion that there are approximately 300,000 tonnes of platinum in the seawater. . .View Full Article
