On the other hand, most of the current lithium extraction techniques require an external energy source. If we use solar energy as the power supply and directly extract metallic lithium from seawater, we can simultaneously achieve the recovery of lithium resources and the conversion and storage of solar energy.

Many people said that gold extraction is uneconomical because of the amount of sea water one has to pump to shore. The energy involved in pumping so much seawater would make it uneconomical. But what if, the pumping cost is zero, I am already pumping for my hydroturbine using renewable energy, I can deliver this amount of seawater flow for free.

In 1900, London inventor Henry Clay Bull filed a patent for a "method of extracting gold from sea-water". The process involved adding lime to seawater to lower the acidity and precipitate dissolved ions, including gold, into solid material. Bull expected substantial amounts of gold to collect, but as far as we know, he never tested the idea.
