ABSTRACT:
The present invention is directed to a solar powered distillation system and method. The solar powered still may have an impermeable nonporous membrane that may be extruded, molded, vacuum formed or sprayed-on. The membrane may be installed in a lightweight basin as a liner. Further, the membrane may have a plurality of fluid reservoirs and an overflow trough. In a preferred embodiment, the membrane material may be an opaque water grade non-toxic odorless, tasteless silicone, TPE, TPR, TPO, or EPDM. In one variation, the solar still basin casing may be molded or vacuum formed and made of ABS, polycarbonates, fiberglass and/or polybutylene. The solar still may further include legs made of PVC or similar pipe materials that are coupled to the still basin with a coupling. The still may include a gasket or seal compressed by a metal and rubber seal stripping to couple a sheet of glass to the still basin.
