dinfinity (2300094) writes "Rice University scientists have unveiled a 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."
