I hear there are lots of precious metals dissolved in sea water, including gold, silver, etc.
Is it possible to build a plant by the shore (say a nuclear one) which evaporates sea water and extracts all these metals?

Thanks for the answers so far, but I guess I did not express my question clearly.
First, please ignore the "energy" requirements. Right now, there are desalinization plants around the Persian Gulf that produce fresh water from sea water by "boiling". And incredibly, they do not even work by nuclear energy, they work by oil - which is much much less efficient. So, please ignore the energy requirements.
My question focuses on two things:
1) Once you boil and recondense sea water to produce fresh water, how do you separate the miniscule metals from the huge salt pile?
2) Once you separate the metals from the salt, how do you purify each metal? There are hundreds of different compounds.
In other words, is it possible to make the currently existing "boiler" desalinization plants more efficient by putting their side products to some use?
Thanks.
