How to get 2000ºF Solar Power

Convert a junk TV into a 2000ºF solar cooker. Here’s a technique for hacking a 4 foot mega magnifying lens out of your old TV, and some of the things you can do with it!

This project should not be attempted without adult supervision and adequate training. Misuse, or careless use, of tools or projects may result in serious injury or death. Heat generated from a Fresnel lens can exceed 2000ºF and cause serious damage to persons or property. Use of this video content is at your own risk.

Project Inspired By:

My “Solar Scorcher” project was originally inspired by Dan Rojas of GreenPowerScience: (Fresnel Lens Giant “Big Daddy”)

Project History & More Info:

These TV’s are old, extremely heavy, and are breaking down on people everywhere. They usually cost more to fix than they could be sold for, so people are begging you to come take them away for free!

I usually find mine on the classified ads under the “free” section, but they are also common on the sides of streets and alleyways where people have left them for trash.

PLEASE NOTE: These lenses are found in “rear-projection” televisions and not all are the same. Some are discolored, and some concentrate to a beam rather than a point. The particular screen I found was a crystal clear acrylic lens that focused to a point. It may have been luck that I found it on my first try, because 3 TV’s after that all had lesser grade lenses, but still produced enough heat to melt zinc. Just FYI! You can also see for examples of these different lenses.

It was brought to my attention that Kipkay did a project like this a couple of years ago that he called the “Solar Death Ray”. It’s probably where FenceKid got the idea, which in turn, inspired me. Check out his awesome video:

  1. Solar energy -> sunlight from the Sun +=+=> Fresnel Lens *=*=-> molten salt ****> molten metal (recycle soft-drink can -> Aluminum metal molten / recycle food cans -> Tin metal molten) == hybrid molten metals thermal energy storage.

  2. Seriously this can be turned into energy with a budget, like dude it's burning at Hundreds of degrees and this can be used efficiently and effectively

  3. I thought when I first saw this “point that bad boy at solar panels” now today they are doing it.

  4. Awesome
    The Egyptians used this technology to melt rocks. One minor criticism, your frame is wood and could catch fire if the kids got hold.of it. Fascinating stuff

    Thank you

  5. I was wondering if the lenses would warm my house (that is made for Texas summers) during those rare winter storms? Shallom you are loved

  6. Grant's one of the few people on this planet who actually have a use for their pickup truck. Sucks he's no longer with us >__<

  7. This is fascinating are you concentrating high frequency photons or the long wave infrared spectrum to achieve the concentrated energy?

  8. Heloo from Bosnia, I like this tip tv so much, and problem is we don't have here TV like this, but If I have chance for one of this, I will love that.

  9. I'm wondering if this could be used to heat water in a closed loop system to pump through the house for free heating in sunny winter days mmmm

  10. Hi
    I have a favor to ask, would you try melting granite, as big of a piece as you can, let it cool down. I just want to see if the granite will have the same properties before the melting?

  11. Aim the fresnel beam through the glass focusing lens of the projector. You might get the explosions you were seeking.
