SUMMARY

TII provided a conceptual design of a passive solar greenhouse for hot and humid arid area wherein water was purified by a solar still located on the roof of the structure and another still covering a solar pond.  The structure encloses several compartments for growing, cold storage, packaging and shipment, control and monitoring room, and administration.  Cooling is provided by fans and a rock energy storage.  The solar pond is used to generate electricity.  Water, nutrients, pesticides and herbicides were provided through a drip system.  The soil was formed by sand and gravel in most of the growth area.  A hydroponic system was also included for special plants.  The cost was estimated at 1 $M per hectare.  The breakeven was about 9 months.
