Abstract:
1. A boiler for generating steam, the boiler comprising a substantially enclosed housing configured to contain an amount of water to be boiled, the housing comprising one or more thermally conductive sidewalls which form a substantially enclosed water chamber and a reflection chamber, the reflection chamber including a closed top portion and a opening through which light rays may pass, the opening being vertically disposed below the top portion of the chamber so that the reflection chamber may trap heat, wherein at least one of the thermally conductive sidewalls is disposed so as to divide the water chamber from the reflection chamber, a support structure attached to or integral with the housing, which support structure supports the housing in a substantially fixed position during use of the boiler, reflecting means for reflecting sunlight through the opening of the reflection chamber and onto a focal point on one or more inner surfaces of the top portion of the reflection chamber, and a feed conduit sized and configured for controlled feeding of steam under pressure through at least one of the sidewalls and into the top portion of the reflection chamber.
