There are about 10 micrograms of gold per ton of sea water. At current prices (rough estimate) 10,000 tons of water contains a dollar’s worth of gold. At the prices I pay, a dollar’s worth of electricity is not enough to pump that much water more than a couple of inches (with pumps a lot more efficient than the one I’ve got now). The magnesium in a given volume of sea water is worth a lot more than the gold in the same volume. So is the salt. In the future, it may also become worthwhile to recover the deuterium.
