  •  May 2015: Solar Smelters Global is now a real live corporation. The company will design the mass assembly line, and market to other companies, worldwide. This Patented device turns out 10,000 degrees, the surface temperature of the sun, which not only can melt rock and glass, it can make steam, hot heat transfer fluids like oil, or hot air (my favorite) to drive a turbine.

  • January 2013: Martin Nix has received patent approval for his 'Half Parabolic Dish Reflector with Planar Reflector Solar Smelter' design. Martin explains that it is an improvement over existing smelter technology, in that it puts the focus of the sun safely into a hole in the ground. That means the focus of the sun is not in the air, where the melted metal can spill on people, or where someone can get injured. The focus or target does not move around, but is stable. Not only can this device be used as a solar cooker, it can also be used to generate steam, sterilize medical instruments, or melt rocks, glass and metals.
