Abstract:
A water sterilizer powered by solar energy is described. A first check valve allows an increment of untreated water to flow from a reservoir into a boiling chamber where it is heated to boiling, and thus sterilized, by focused solar energy. A second check valve with a higher cracking pressure than the first valve remains closed, holding the increment of untreated water in the boiling chamber until the pressure of steam forces the second valve open, thus evacuating the chamber of now-sterilized water. Once the chamber is evacuated, the second valve automatically closes, and the first valve automatically opens, allowing another incremental sterilizing cycle to begin.

Claim (Index 10):
A water sterilization system that boils water in increments, comprising:\n a) a water reservoir with an outlet connected to an inlet side of a first check valve,\n i) the cracking pressure of said first check valve is selected such that the gravity-induced pressure of water from said reservoir allows water to flow past an outlet of said first check valve; \n b) an outlet of said first check valve is connected to a first port of a boiling chamber, said chamber including means to absorb focused solar energy; c) a second port of said boiling chamber is connected to the inlet side of a second check valve;\n i) the cracking pressure of said second check valve is selected such that the gravity-induced pressure of water from said reservoir at the location of said second check valve does not allow water to flow past the outlet of said first check valve; \n ii) the cracking pressure of said second check valve is further selected such that the pressure of steam created by water boiling in said boiling chamber allows said boiling water to flow past the outlet of said second check valve; \n d) a means to collect and focus solar energy onto said boiling chamber, whereby, water from said reservoir can be boiled and thus sterilized in increments as said check valves allow water to enter said boiling chamber, and then exit only when boiling.
