No glass Fresnel Lenses like this. Lighthouses and 2K stage lighting is the closest thing but they are not right type for solar. Overhead projectors are usually 4 Linear Lenses overlapped to make a spot and sandwiched between glass. Their focal length is way too short, usually only 5 inches
The energy is not enough of a catalyst to keep the wood burning. It is enough for the paper but not wood, it requires longer exposure. Gun Powder or Thermite would have no problem staying lit though.
That Just happened. It was fine for months. Weird, Thanks for telling me. I have one other video that 20 seconds of black was added at the end. Any ideas.
I do that with my glasses. So what?

Where can I purchase one of those? Very useful and can save alot of money by using those instead of cooking on gas inside the house.
