Kyoto Trough, is it greener than the Kyoto Box? Answered

The idea behind the Kyoto Trough is to use a parabolic trough (rotated inwards round its focal line) so that all the light it collects over a certain time (1 2 3 or 4 hours) focuses BELOW the focal line. Then you use other troughs (probably facing at right angles to the first one) to concentrate this light further onto the cooking pot. I have done a rudimentary test in software and the concept does work there. I think it will also work as a panel cooker. It is very important to line up the primary trough with the path of the sun across the sky. It should also work as a panel cooker. Just a much longer panel cooker with the v shaped little wings like in the diagram Or perhaps a panel cooker with just one "tail" going up in the air and insulation on the back half of your cooking pot? (taking away one half of the device) Thanks Brian

I am sorry, I had the movie software timing in seconds and didn't notice that it was too long. Youtube didn't tell me either.

I think your video got removed by Youtube. Message says it is too long, cannot be more than 10 minutes.
