I have a 50" Lens from an older big screen TV, I wonder how big I can blow up my iphones images? Hmmm... and yes, it starts a fire very quickly in bright sun!

i believe that some of the first bigscreen tv's used a similar approach but used 3 light projectors on the Fresnel lens. If you take one of these lenses out of a tv you can burn almost anything thekingofrandom has a video on it.
