Solar water boiling device

Patent ·
OSTI ID:5863007
A solar water boiling device having an insulated enclosure with an opening in its front provided with a light-transmissive cover. Within the enclosure is a water container preferably formed as a discrete unit separable from the enclosure. The enclosure provides insulation such that heat losses through its side and rear walls are small compared with heat loss through the cover. The depth of the container measured perpendicularly with respect to the cover is 4 cm or less permitting water filling the container to be raised to the boiling point in one day of exposure to full sunlight.
