Good idea with the glass over your lens. I've had trouble with them fogging up from UV exposure, or the ridges in the lens getting gunked up with dust and moss. The glass should protect from both
Dead Meme clear epoxy is still not 100% clear, so it would scatter some light and thereby reducing its effectiveness. I recommend using acrylic which is 99% clear (compared to soda-lime glass at about 70% clear), but make sure you seal it so it doesn’t oxidize over time and get cloudy (specialty plastic clear coat spray exists for such a purpose) This is also why “glasses” are actually made or CR-39 plastic or polycarbonate for lenses now since it’s lighter and is a lot more clear for vision

I did this once with a fifty inch. Set pocket change on a concrete stepping stone to melt. Thought it would take a bit so went in the house and made a sandwich, had lunch. When I came back, not only was my change fused but due to the movement of the sun, there was a line of glass where it had melted the concrete. Good times!

youtube: watch a guy "burning stuff with a giant fresnel lens" me: i wonder what will happen if you focus into a solar panel backyardscientist: first i want to overclock a solar panel" i freaking love you dude.
@@NikosPer It is simple: Let's take a 1 square meter solar panel and a 4 square meter focusing lens. Normally, without the focusing lens the solar panel would catch a 1 square meter area worth of solar energy, it is said to be about 1000W. The focusing lens will capture 4 square meters of energy (minus the losses, they took roughly 40% losses in the video, so we will do the same), so 4000W, 60% of that is 2400W. So the focusing lens will project about 2400W onto the 1 square meter of solar panel. Giving you roughly 2.4 times more energy than normal. These are not exact numbers, just a rough guess to show you the point. You don't want to focus too much energy onto the solar panel as it will melt the material, as shown in the video. Also, in practical application, you would need to install several small mirror in a dish shaped area, moreover they would need to be moved all the time with the sun, so it is not possible to use this to super power your solar panels.
Done this, it's super fun and almost instantly chars wood to just straight carbon. If you scrape the burned powder off multiple times you can slowly burn through a 2x4. Also, melting pennies then sliding them into cold water makes some super interesting warped pennies
You burned a hole in a solar panel. With the sun. Surely there is some poetic irony in there SOMEWHERE. And i'm looking forward to a video on Shopping Cart sailing >:3 I'm just kidding.
@@THESLlCK I hear this argument a lot and have my doubts especially as many Teslas have been on the road 200k+ miles and only have 10-20% range degradation. Its also to my understanding Tesla either has a recycling program or is engineering one. Not only would they get the good PR it lowers cost of producing new cells by reclaiming raw materials. I haven't looked into what percentage they can re-use but we'll see!

What's interesting is that, unlike other ways of cooking or smelting, this is actually heat-neutral, b/c the heat is achieved by concentrating sunlight that would otherwise hit the earth anyway, just distributed accross a greater area. I've been thinking a lot lately about the importance of finding heat neutral (or negative, if that's possible) methods of powering our activities. Even our air-conditioners are not producers of heat; they work by moving a substance through a tube, compressing it at one end thereby concentrating the heat, blowing it with air so the air heats and it cools, then expanding it on the other end so the heat disperses, and then blowing air past it so the air cools down and it heats back up, rinse, repeat. This is heat neutral, but electric grids powering such machines often make the world hotter. Ideally, it's solar, but if it's wind or water, if you think about it, it's taking kinetic energy on a macroscopic scale, and using it to generate current through a wire, which heats up, i.e., produces movement on a microscopic scale. Coal plants, on the other hand, are much worse; they take chemical potential energy and, well, they just slopilly cross out "chemical potential," transforming it into usible electricity and kinetic energy, but also, into tremendous amounts of heat, which isn't even the worst of it, but I doubt anybody doesn't understand greenhouse gases at this point.
My family had a rear-projection tv many years ago. This one had 3 lights in the back - red, blue, and green. One day I learned there was a setting that allowed you to change where each individual light's focal point was, so that if something was off kilter you could adjust it back to where it should've been. After a little tweaking of the red and blue channels, turned it into a pseudo-3D television. Had to have those old-school 1 red lens, 1 blue lens glasses to get it to work and the effect wasn't great since nothing I watched with it was made for 3D, but things did look more three dimensional. At any rate, it was a neat little science experiment.
I had a little 1 ft square (rigid) Fresnel lens from Edmund Scientific when I was a kid. It would focus the light into a circle about 1/4 inch in diameter, and it would melt bricks and cause pavement to explode. This was much bigger, of course, but I was doing it in the front yard.
A couple years ago we ended up with a friend's junk projector TV.. but after not being able to fix it, just ended up throwing it all out.. Now I'm really annoyed we didn't save the big lens thing. damn.
Hey bro love the videos keep up the good work. I think you're one of the soul UA-camrs that are able to deliver fun and entertaining video footage while still being educational. Thanks 😊
As an AV tech, just dropped in to shout out your (fairly rare) correct pronunciation of the word "fresnel." It was named after someone, after all. Credit where credit's due.
That's true! Or at least have fun doing it :p I was thinking I could make it track the sun, attach a solar cooker to it, or something to distill water but then a small project turns into a huge thing ya know?
It would be worse than this. The goal is to have as much SURFACE as possible. meaning you'll have to build a bigger fresnel lens, or put lenses next to the center, then use mirrors to redirect the light to a center point ( and using different focal lenghts, because the light ray for adjacent ones would be a lot longer.
I made a whole series of this before grant and you, gotta love it! They are fun to play with. You can boil water with it too. Solar cooking with this is a thing as well. I do have a play list on my channel, sadly it did not get 400k views like yours.
My brother has a 9x12 magnifying glass tray thing. We were messing around with it outside and we were quite surprised with how strong it was. We burned words into real leather boots, melted the garbage bin, set the grass on fire etc. We weren't expecting it to work so God.
Shaving cream cans are great for exploding. I once stuck one in a fire upside down with the top below the coals. Blew the top off of it and it shot up straight like a rocket on a column of foam. Neat!
Now, imagine taking a screen with a one mile radius to space (outside the Van Allen Belt) and focusing the sun’s UV rays onto a single point the size of the penny. No flames could form, but energy would be HIGHLY concentrated on that single point.
I boiled a 2oz lead fishing weight in under a minute with the fresnel lens out of a Mitsubishi rear projection TV & it would catch wood on fire instantly! I had to keep a blanket over it & store it in my shed because even light coming through the window & hitting it could have started a fire. Mine was that powerful straight out of the TV, you can also polish them to make them reach temperatures above 2000°F!

Love you videos! The only thing that annoys me is that you edit in 60 fps... You get so much more out of showing the slow motion clips in 24 or 25 fps.
In order to help keep the direction of the sun to the lens at 90 degrees I screw a small 1/2" id X about 2-3" long tube to the wood frame. For storage you turn it so the tube is parallel to the lens. To power up you turn the tube 90 Degrees to the lens and turn the lens so you can see the sun through the hole in the shadow of the tube on the ground. Since there is a nail or screw through the tube you will get a circle of light split in two. Simple quick and easy. You could use something like a chopstick but something hollow is much easier to get in aim.
