I built this compound parabolic dish collector from the templates posted by Gaiatechnician on instructibles. I didnt want to create a mould so I skipped that part and dived directly into making the twelve petals. I will post after Ive made my stand for the pot and completed the frame that could be positioned facing the sun.
Cut out the 12 petal shapes given by gaiatechnician and paste reflective material onto it. Tape the back ends together and form the segments into a circle and tape the last one to the first one.
I bought irrigation pipes and fittings to make a lightweight circular frame and will complete it on Monday.
