Dad helps kids invent solar oven for third world

by James

Cool dads are the ones who spend time with their kids playing and creating stuff. REAL cool dads are the ones that help their kids change the world. And Jon Bohmer is a REAL cool dad. Working with his two girls, Jon has created a solar oven out of about five dollars worth of cardboard, foil, and acrylic which can generate so much heat, it can bake bread and even boil water using nothing but the Sun. How cool is that? Here’s how it works…

With two cardboard boxes, Jon paints the inner box flat black and wraps the outer box in aluminum foil. Then, he slips the black inside the foil and covers it with the acrylic sheet and points it towards the sun. This setup concentrates and captures enough heat to create temperatures in excess of 350 degrees and it does it without burning so much as a stick of wood – which contributes to deforestation and global warming.

Scouts have been creating cardboard ovens for years, but not with a solar capability. Just by harnessing the power of the sun in a way that would make any Scout proud, Bohmer’s device will boil water and cook food which will save millions of lives who die from drinking contaminated water.

The Invention – which Bohmer said took an afternoon to create and costs less than $5 in materials – won the FT Climate Challenge award for the “most innovative and practical solution to climate change.”

This is not a new invention… I bought one of these solar ovens a while back, they have been used for years in poor areas, and the only thing this guy did is replicate the idea with cheap stuff. Is it considered an invention if I just recreate something that exists with old cheap stuff? Hmmm, how could I get an award… make an iPhone out of duct tape & old wires? ;)

Wow, only $6 for the oven? I gladly stand corrected, that is a valuable invention, especially since it is affordable to people in areas that need it due to economic reasons. Thanks for the clarification-
