Dad helps kids invent solar oven for third world
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.”
