Thompson’s “solar scorcher” device.

Plastic sheet focuses sun light to the point that it can melt pennies, boil water, more Grant Thompson, also known by the online moniker “The King of Random”, has posted a wildly popular video on YouTube in which he hacks an old, 50-inch TV to remove a plastic sheet from it for use as a “solar scorcher.”
Thompson’s “solar scorcher” device.
A bit more specifically, Thompson removed the TV’s front screen and separated the three parts that make up the component. Of the pieces, the TV’s Fresnel Lens displays a perfect ratio, Thompson notes, as it allows him to focus the sun’s rays onto a tiny spot or target.
The target spot which a TV’s Frensel lens creates.
When focused, the temperature on this spot reaches 2000 F which, as Thompson demonstrates, is hot enough to ignite wood, melt pennies, explode glass bottles, melt concrete, and more. Much more as a matter of fact.

What’s particularly noteworthy about this project is the fact that when the lens is unfocused, it’s harmless. Only when it’s positioned right will it super-focus the sun’s light.
The following videos come from this project. The first is a demonstration on how Thompson hacked open the TV; after that is a 4-minute clip that shows Thompson burning various objects.

He’s thrown down the gauntlet...time for Thunderdome.
Two men enter, one man leaves!
Do the computation ~ 4’ wide ~ hardly a child’s toy. Tremendous amount of light gathering power.
How's that going to work? Don't zombies only come out at night? How do you focus the sun's energy at night?
Apparently this is the first time somebody noted that since Galileo.
zombies don’t care if its night or day, unless its entitlement zombies who wake up after noon

Cool!
Wow. On punch cards? Students should have to program on punch cards.
Ya. Kind of cruel. Hopefully they didn’t suffer too long.
This is a professionally made product ~ we made a REFLECTIVE version which is mathematically the same ~ but this device in this video is smaller than the one we made ~ http://bclee.net/lens.html There are a good number of videos on u-tube that’ll teach you all about this type of lens. One of the advantages to a reflective fresnel lense is you have a fixed focal length so you could set a hunk of meat at the focal point and cook it while the Sun moved ~ our experience demonstrated you have plenty of time to cook before needing to realign the lens.
Everything I know about zombies which is very little I learned from watching "I am Legend". Are those some different breed of zombie?
Our 24 inch CRT TV from 1988 outlasted all of our tube TVs including our DLP. We gave it to my wife’s grandmother when we bought our DLP. Still running, with a decent picture, when grandmother went into a nursing home.
I suppose every writer and filmmaker have different visions of them.
LOL, no punch cards. We have a lot more programs and languages to learn than you old timers. :)
Cool, thanks for the link.
My brother got sent to the principals office for frying ants with a magnifying glass. They still had a board of education. Used it on him too.
Ya. Your typical modern program would require a lot of punch cards.
I regret tossing my punch cards a few years ago. A bit of a novelty now.
The irony is that there are probably some computer systems that still use FORTRAN. Probably as old as the hills... like me. :)
Guess they had a zero tolerance policy even back then.
