In 2008, I ordered a parabolic solar cooker in India. Over the months, I experimented different dishes and ways of cooking. This cooker is very efficient, the most efficient pot I found is a black cast iron pot. I have created a web page to describe the solar cookers I am selling. In June 2009, I helped Stan and Jane from Sizzling Solar Systems to tend their stall at the Brisbane Greenfest. That was a great experience.
