Summer is almost here and for many that can mean it can be hot enough to cook an egg on the sidewalk. That’s not entirely practical, but British engineer James Bentham created the Solar Kettle, which can bring water to boil from the power of the sun’s rays. It is light enough to carry in a backpack and unlike a thermos can heat the water for cooking/
This portable thermos-like product utilizes a special thermal technology that requires no power – just a sunny day and a couple of hours.
