Fresnel lens GIANT BIG DADDY boiling water with solar FRESNELPARABOLIC

This Lens is one of my giant solar Fresnel Lens in my personal collection. It is a spot lens measuring 1.4732m x 1.143m and has a 1500mm focal length.
This lens delivers 1.6 sq m of concentrated sunlight to a 25mm area. We are developing a quad section version of a lens slightly larger than this one.
