Abstract: The present invention is a non-bursting pipe which has an inner layer of copper and an outer layer of high carbon steel. The pipe is shaped such that its area of cross-section can increase under the pressure of expanding water when water cools below 4° C. When water turns into ice at freezing temperature in severe winter the area of cross-section of the pipe can increase enough to accommodate the increase in volume of water when it turns into ice. This saves the pipe from bursting and causing any damage to properties. When in warm weather ice inside the pipe melts the area of cross-section of the pipe decreases by spring-like action of the high carbon steel layer. The non-bursting pipe is now ready to face another severe winter and to save the water supply from any damage.

Abstract: A double-walled insulated cooking pot has a food vessel, a sleeve positioned around the food vessel, a first insulator, and a second insulator. The insulators are affixed between the food vessel's wall(s) and the sleeve. The outer surface of the wall(s), the inner surface of the sleeve, and the insulators define a vacuum space. An insulated cover for the cooking pot has an upper layer, a lower layer, and a cover insulator. The cover insulator is sealingly engaged with an outer edge of an inner surface of the upper layer and an inner surface of the lower layer. The upper layer, the lower layer, and the cover insulator define a vacuum space within the cover. The pot and cover can be constructed such that the surfaces of the vacuum spaces are reflective.
