We have the same problems regarding on this, carbon nanoparticles will be my last item to do this solar steam but I don't know where to buy it. Is there any local store selling carbon nano particles? I've been there also in a hardware store but they don't have any of this.

Looks promising. Any updates on this?

Solar Steam Breakthrough Using Nanoparticles

"Our particles are very small even smaller than a wavelength of light which means they have an extremely small surface area to dissipate heat. This intense heating allows us to generate steam locally, right at the surface of the particle"

"Rice graduate student Oara Neumann videotaped a solar steam demonstration in which a test tube of water containing light-activated nanoparticles was submerged into a bath of ice water. Using a lens to concentrate sunlight onto the near-freezing mixture in the tube, Neumann showed she could create steam from nearly frozen water. "

"Solar illumination of broadly absorbing metal or carbon nanoparticles dispersed in a liquid produces vapor without the requirement of heating the fluid volume. When particles are dispersed in water at ambient temperature, energy is directed primarily to vaporization of water into steam, with a much smaller fraction resulting in heating of the fluid."

"they are using particles about 50 nanometers or so" "if you want to experiment india ink made from soot should work for this"

Now I am wondering where I can buy some carbon nanoparticles of the right size! Maybe some scientific supply house?
