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.
Thompsons solar scorcher device.
A bit more specifically, Thompson removed the TVs front screen and separated the three parts that make up the component. Of the pieces, the TVs Fresnel Lens displays a perfect ratio, Thompson notes, as it allows him to focus the suns rays onto a tiny spot or target.
The target spot which a TVs 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.
An egg after it was exposed to Thompsons DIY laser.
Whats particularly noteworthy about this project is the fact that when the lens is unfocused, its harmless. Only when its positioned right will it super-focus the suns 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.

You mean this one?
Someone must have manufactured these as subcontractor to large screen tube TVs. Why can't they be still available somewhere?
It is the perfect tool for a cheap power solar still quickly to produce large quantities of safe drinking water.
Limited only by human imagination.
this guy better watch it or ATF will kick down his door looking for him and his unregistered destructive devices.
I learned COBAL in college and Asembler language. Used a bit of COBAL in my early carer but got in with a bunch of UNIX guys and been doing that for over 20 years now.
Thanks.
Do they also carry the Tesla Death Ray?
Here where?
I remember in the late 50s our engineering firm sent calculations off to be processed at Stanford Research to be processed at night on one of their IBMs. A 360, I think.
As part of the available service, we could write our own structural and geodetic programs in FORTRAN.
I would love to try that again with modern PC processors which would embarrass those old multi-million dollar machines.

You got that right!
An assault lens, if I ever saw one.
Killer commute!
About 3000 miles?
“Must find old 50 tv...”
I’ve got one in my living. Damned monstrosity WON’T die! 5000.00 in 1994. Apparently it wasn’t a ripoff.
“I would love to try that again with modern PC processors which would embarrass those old multi-million dollar machines. “
I recompiled a FORTRAN program for my PC (286) and it ran so fast I did not believe it. It was done in the time it normally took for the network to query the VAX 725 and back.
Well, I checked the results; they were identical. I never went back.
energy source, anti-Zombie weapon after SHTF?

BALONEY!!!
[Great magnets]
You want some powerful magnets, just take apart an old hard drive and take out the magnets. Put one of those on your fridge and you almost need a clawhammer to get it off.
That’s some serious longevity. I’d say it wasn’t a ripoff.
