Gold from sea water (new technique)

 · But let’s say the break even point would be on oz of gold per device. The concentration of gold in seawater is about 13 ug/m^3 (not 1.3 mg), so to extract one troy oz of gold you would have to process about 2.3 million M^3 of seawater. If the device could average 10 liters/second it would do that in about 7 years. That's a tall order.
