OMG…I never put two and two together. LOL now I love fresnel lenses. We use them to induce prism and are a pain to apply….net tv that goes out…solar oven. Kinda feel bad putting them on glasses now.
yes, but will it float?
Oh and don’t clean these with windex! It makes them cloudy.
@elijahvivio1996 elijahvivio You bet! Make sure you separate the Fresnel Lens from the other screens carefully. Make a frame around the edges to keep it flat when you use it. Pine works but it warps if not stored flat. Like a picture frame. (pine also gives you splinters if its cheap). It works well when the side with the Fresnel pattern lines faces the sun. Be sure to use eye protection. Sunglases are not enough. Get welding goggles. They are not expensive and worth it to save your retinas
@pigpal2 GPS website or take them out of the screens of old (1990′s) rear projection screen televisions (Hitachi, Mitsubishi, Toshiba, etc) The better spot lenses come from non-HD analog projection models. “Free Energy” does not have to be expensive.
honey yummmmm……….

make one the size of a house.
then california.

I had a fresnel lens that was one of those old TV screen magnifiers. ou could turn a small TV into a larger viewing area with it. I took it outside once to use it in the sun and was amazed at the power. It was so powerful that I could hold it on a piece of wood and run water from the hose and the wood would still burn.The water would boil away instantly and the wood was still on fire. I was afraid to keep it around the house so threw it away. Dumb move.These should be used for power generation.
@luiger123 star ship troopers should take history lessons and learn about frennel lenses!
it would suck to have a pair of eyeglasses that were fennel lenses, ones eys would get fused to their skull so fast. it would be terrible.
I wonder what this means to a professional glass artist
@pigpal2 check our website:-)
where can i get this? I WANT ONE SO BAD!
6,000°C = 10,832F not 9800F sorry racheetah
just for kill gigants ants! xD
@Akathepriest
No, you can’t. The sun provides the energy, not the lens. So a bigger area to collect sunbeams is the most significant way to improve this “experiment”. Pretty sure your focus area is smaller, so most likely you will be able to melt small amounts of glass for example. Need a steadier hand though.
melting metal= super hot glue
Can you try to melt some coins?

this fresnel len can use on the ants hole and kill it all ants
this is great I love it!
der, like how hot does it get, der
If the TV is pre 1995, it is good, newer tvs are view all angles. So they do not provide a clear lens. They actually are fuzzy and diffused.
i have been told that the screen from a projection tv can do the same thing (focusing light, starting fires etc.) do you know if its a fresnel lens also?
