Andy Lenss: Solar Cooking and Water Pasteurizing with Available Materials

Andy is a solar problem-solver: How to get the best of a parabolic, box, and panel cooker in one design? Can you make a water pasteurizer just using materials on hand--and in the ground? What is the bare minimum one needs for a tracker to follow the sun? Three innovative designs answer these questions in this conversation.

Does Andy have an email? I’d love a pattern of that parabola reflector.

Send me a note to the email listed in my "about" section, and I can forward to Andy :)
