Solar Fresnel Lens and a Tevana Tea vacuum container + steel wool nanoparticles. Superheated http://www.greenpowerscience.com/ steel wool creates nanoparticle surface structure.
The steel wool has a vast surface area, when superheated dry, the smooth shiny surface structure opens up creating structural crevices less than 100 nanometers that act as nanoparticles. Any previously mirrored metallic object that is dulled with heat alone has this micro structure. This is different than sanding. The direct contact with the aqueous solution allows for optimal heat transfer from the heated metal surface to the water. Steel wool is a good choice over mud bath nanoparticle suspensions as the skeletal structure allows for enhanced area coverage in 3 dimension vs that of a 2 dimensional mud bath.
Green Job Career Training. BOILING WATER. I am working in a very efficient boiler that can retain more heat. The concept can also be used in the large Stirling Engine. If very little heat escapes from the boiler or displace side of a Stirling Engine, the efficiency and power will go way up.
