Scheffler systems: Wolfgang Scheffler has developed, promoted, and installed a number of systems using a heliostat to focus sunlight onto the bottom of a cooking surface or onto a heat storage drum.

• http://solarcooking.org/funnel.htm Use of a solar cooker (funnel shaped rather than the more common parabolic or box versions) not only during the day, to cook, but also during the night to radiate the heat of the vessel into space. Apparently, shielding the vessel from local sources of radient heat (buildings, trees, etc...) and reflecting its own heat out into space allows for impressive cooling. 20' F difference from the outside air temp. And on a 50' night, it actually formed ice!+

• http://www.princeindia.org/newproducts.htm#a5 A very nice parabolic cooker that heats the dish from the underside so it can be used for frying, roasting, etc... Has a cutout area on the back with a shade to allow easy access to the cooking vessel.
