Solar design Jig and "clam shaped" reflectors

Great ideas... Can you design the template to make these dishes/light tubes so we can use them to makes some test items. You could post the desgin templates somehow. We'll then physically make them to see how well they work in reality. Tx. Bob

I love back yard scientists so much! Keep thinking and keep tinkering! Together we will do our part in reversing a big part of our global problems!
