ABF Solar's 45" diameter concentrating mirror dishes focus sunlight to a 4"-6" diameter hot spot that can develop 1000F (537C) on a clear, sunny day, resulting in  

slightly more than 1kilowatt of thermal energy  per hour. 

1 kWth/hr.=  1000 calories,  or 3,412 BTU .

A single dish can be used to directly place this hot spot onto a cooking surface, a piece of metal for annealing or tempering , or any other item you desire to heat.  Many cooking pans and ovens have been designed to accommodate these needs.

Note that the dish must be re-positioned ever 5 minutes or so as the sun moves.

We have designed a sun tracking fixture that holds two dishes, and makes these adjustments much easier to accomplish.

We have also automated the fixture with motors and electronics that will  adjust the dishes automatically, which should be ready for sale in the coming months.
