Device for extracting and storing heat from sunlight for cooking

摘要

High temperature produced in a narrow channel by appropriate optical means e.g, lenses (7) and mirrors (8) can be stored in a suitable fluid. Heat exchange between stored fluid and container (1) takes place in a specially shaped container area designed as a trough which is hollow and conically shaped and which can accommodate cooling pots or baking tins of corresp. shape. Thus the capacity of any one pot depends on the distance between the pot base and the lid. The associated steam pressure facility is in the pot lid and is supplemented by a ring placed below the pot lid to control the pot insertion depth. The container or tank is twisted round to suit the sun position, the container connected to the trough flexibly to maintain the level position.
