NOVELTY - A solar energy powered apparatus comprises a collapsible concentrating mirror (40) comprising a flexible reflective sheet and a minor frame (44) comprising a forming mechanism to support and shape a reflective sheet so that it concentrates solar energy.    USE - A solar energy powered apparatus is for distilling liquids, e.g. water.    ADVANTAGE - The flexible mirror increases the amount of water distilled. The two part distilling chamber allows the user to easily disassemble the device for compact storage or cleaning. The flexible sheet mirror is made from inexpensive and lightweight materials, which can be rolled up or stacked compactly for shipping and is easy to assemble. It increases the amount of sunlight falling on the distilling chamber several fold, increasing by the amount of water that may be distilled in a given amount of time. The surface of the mirror does not have to conform exactly to a precise curve that allows lower cost materials, loser tolerances, and simplified shapes to be employed in its manufacture. The apparatus is easy to operate and inexpensive to maintain and minimizes waste of material and solar energy.    DETAILED DESCRIPTION - A solar energy powered apparatus comprises a distilling chamber (10) comprising an evaporating basin (12) and a condensing roof (14) having a pair of interior channels running the length of condensing roof and a reversible mechanism for holding the condensing roof on the basin to form an airtight seal. A collapsible concentrating mirror (40) comprises a flexible reflective sheet and a mirror frame (44) comprising a forming mechanism to support and shape the reflective sheet so that it concentrates solar energy. A stand supports the distilling chamber above and at the approximate focus of the concentrating mirror. An exit tube (18) removes a condensed liquid and includes water, which collects in the channels from the distilling chamber. An input mechanism adds a raw liquid, including water, to the evaporating basin.    DESCRIPTION OF DRAWING(S) - The drawing is a perspective view of a solar distillation apparatus.
