3. Scheffler Community cooking system.
   Scheffler Cookers is a revolutionary concept developed by Wolfgang Scheffler. This innovative cooker permits the reflector to be mounted outside the kitchen while the focus inside the kitchen permits indoor cooking. Many such community cookers are in use all over the world.

4. Community Steam Cooking system.

    

   Based on Scheffler Technology few community cooking systems are developed and are in use at different locations in India. In these systems the steam is generated by using series of Scheffler reflectors at roof top. This steam is transported in kitchen through insulated steam pipes and food is cooked in special vessels on this steam.

   Mr. Deepak Gadhia and Shirin Gadhia have the honor to put Scheffler technology in use for large scale community cooking in India. They work in association with Wolfgang Scheffler. Mr. Gadhia has supplied and installed the world's largest solar cooking system at Tirupati, which cooks more than 30000 meals per day. Similar systems for 20000 meals per day at Mount Abu and for 6000 meals per day at Shirdi have been installed.

6. Solar Vegetable Dryer:

   A Low cost solar vegetable dryer, which uses transparent polyester sheets instead of glass and collectors made of powder, coated steel sheets in place of aluminum sheets. Fabricated structure has the walling of the polyester sheets. An electronic circuit to control fan speed is used for temperature control inside the chamber. Simple design and lower cost of the equipment will make it financially viable for farmers to manufacture and use at local level.

   Can also be used as Air heater, for industrial applications.

   Technology is available free of cost with PRINCE.
