Solar collector and cooker

摘要

A solar collector comprises a spherical reflector dish focussing on to an element to be heated or a photovoltaic generator. The spherical reflector dish is mounted on a base and has a sun locating means 3. The solar collector may be formed from flat triangular elements which may be laser cut and scored on their non-reflective side so that they can be folded. The sun locating means 3 may comprise a square tube which intersects the dish creating when it is aligned with the sun an equal sized image on the ground. This may used to aligned the dish towards the sun. The element may be attached to the dish using studs 14 and a cord and hook arrangement 13.
