It is cheap.This compact arranged film of metal nano-particles swims in seawater surface, and the local phasmon of nano-particle strengthens
Effect then causes the surface seawater of film liquid interface to be rapidly heated, and produces fresh water steam, and the loose structure on film is steam
Escape and provide effective passage.This new material has satisfactorily resolved Second Problem.Solar energy makes surface seawater be rapidly heated
Fresh water steam is produced, necessarily causes surface seawater temperature to be higher than lower floor's ocean temperature.It is light obtaining with lower floor's seawater condensing steam
Lower floor's sea water is heated while water, heat is recycled.If finding the feasible program for realizing this technical though, the 3rd
Problem is also just readily solved.The solar energy sea water desalination apparatus of above three are comprehensively solved the problems, such as, necessarily can be solved coastal
Area and island water supply problem.
Regrettably, such solar energy sea water desalination apparatus also do not occur so far.
