In accordance with the present invention, there are provided solar water heaters tat are portable, efficient, inexpensive and easy to use. In its simplest form, the solar heater includes a transparent container such as a bag or envelope that contains at least one energy converting structure and has sufficient insulation to enable heating water to a temperature of at least 60 DEG C for a time sufficient to achieve pasteurization, typically a period of about one hour at this temperature, and preferably to a temperature of at least 70 DEG C, at which temperature, a period of only about 6 minutes is required for pasteurization. Invention solar heaters are particularly useful for pasteurizing water. In additional embodiments, invention solar heaters include additional features, such as, for example, a water pasteurization indicator. In accordance with another embodiment of the invention, there are provided method for pasteurizing water employing solar heaters described herein, as well as kits suitable to convert any transparent water tight container into a solar water heater.
Description
technical field [0001] This invention relates to the field of liquid heating, and more particularly to the pasteurization of water using solar energy. Background technique [0002] Current solar water heaters of this type typically include a water-holding container made of glass, metal or polymeric material, which may also be supplemented with an energy-absorbing colored material. The disadvantages of current designs are that many water heaters are bulky and expensive to manufacture, and some others do not efficiently absorb, conduct, and adequately store enough heat to achieve temperatures sufficient for pasteurization. Furthermore, many current designs do not have access to the temperature at which the water is pasteurized. [0003] Most diseases in developing countries today are infectious diseases caused by bacteria, viruses and other microorganisms. These bacteria, viruses and other microbes live in feces, such as human and animal waste, and have been found in contami...
