Experiment with unusual for solar cooking materials and colors

On September 30th 2016 Holger Sauer demonstrates applicability for solar cooking of materials and colours undeservedly considered unfit:

  • white ceramic pot: one litre cold water was heated up to 81 °C for 60 min between 10:30 and 11:30 h

-   Pyrex-type transperant pot: half a litre up to 100 °C for 20 min between 11:50 and 12:10 h.

The experiment shows that each of these two pot types may find application in solar thermal food processing, particularly in case of a powerful parabolic.

I am glad you are teaching Bulgarians this wonderful technology. Now they can fall in love with solar cooked food. I think it tastes better than regular cooking. ( Sent to the Facebook-page of HoSa Solar, August 8, 2016)
