Researchers create solar steam using nanoparticles at Rice University
Rice University scientists have unveiled a revolutionary new technology that uses nanoparticles to convert solar energy directly into steam. The new "solar steam" method from Rice's Laboratory for Nanophotonics is so effective it can even produce steam from icy cold water. Details of the solar steam method were published online today in ACS Nano. The technology's inventors said they expect it will first be used in sanitation and water-purification applications in the developing world. Read about it at http://news.rice.edu/2012/11/19/rice-...

The solar steam device developed at Rice University has an overall energy efficiency of 24 percent, far surpassing that of photovoltaic solar panels. It may first be used in sanitation and water-purification applications in the developing world. - (bold emphasis added)
