It was one fine day. It was clear and sunny, perfect for solar cooking.
So we have decided to enjoy our afternoon tea using Scheffler reflector. We felt the tea was tastier since we didn't use fossil fuel at all to boil the water. And it was a lot more relaxing and fun to cook with the Sun!
Scheffler reflector that we used to boil the water is a flexible parabolic reflector which rotates around an axis parallel to earth-axis, synchronous with the sun. It is very easy to use and highly efficient since the focal point does not move throughout the day while it tracks the sun.
