Have you seen the video with 50″ Fresnel Lens that is converted into a 2000F solar coocker?
Yes, 50″ is very effective, but this is very expensive – you need money, track and help to get it, but for less that $10 you can get 14″. I own it and it works too.
It’s men size, but it’s ideal for her. Look at diamonds on a rotor of self-winding.
