VOTW: Man Makes ''Death Ray'' with Satellite Dish
If you’ve ever used a magnifying glass to melt poor, defenseless, little green army men, then you’ll appreciate what Eric Jacqmain from Indiana has done.
By decking out a regular fiberglass satellite dish with 5,800 3/8" mirror-tiles, he’s created a ‘death ray’ with a focal point that he claims is 5,000 times hotter than the sun.
“When properly aligned, it can generate a spot the size of a dime with an intensity of 5000 suns!” writes Jacqmain. “This amount of power is more than enough to melt steel, vaporize aluminum, boil concrete, turn dirt into lava, and obliterate any organic material in an instant. It stands at 5'9" and is 42" across.”
Unfortunately, the dish died a horrible death in a shed fire. But don’t be sad! He’s making another one, and this one will have 32,000 triangular mirrors. We can’t wait for the video.

5,000 times hotter than the sun? I highly doubt that. Look how "small" that thing is. Lol at the dude not wearing gloves. Also, it doesn't even look like you could fit 5,800 mirror tiles on there..
Mount this thing on a few cruisers with a few modifications to angle the beam and somehow project the beam over a few miles and we'll pretty much own one half of a day
"Unfortunately, the dish died a horrible death in a shed fire."
Hint: When placing your Death Ray in storage, aim the shiny side away from your shed.
I wonder if this is the reason Dr evil took so long to put laserbeams on his sharks, it just wasn't small enough and needed sunlight!
Oh and I would wear a welding shield so I don't go blind
the sun is 15 million Celsius, est., if that thing could put out the same temp as the sun, there would be no video of stuff cooking, it would literally burn it all into ash the moment it touched, heck would prob even catch fire before it touched the beam.
Someone needs to forward this to Mythbusters! They tried making one and failed.
yeah by reflecting an infinitesimal amount of sunlight, after it's traveled 91million miles and then through our atmosphere, he's absolutely able to produce a heat 5,000 times > the source of the radation he's reflecting... what a douche.

Then again, they didn't have nearly as many mirrors, and focused to the precision of a satellite dish. These dishes are designed to bounce a satellite signal to a small receiver in front of the dish. Replace this signal with light, and voila.
It's ingenious.
Note to others: Light intensity doesn't = heat.
He's building another one that will die a horrible dead in an even bigger fire.
mitght it works like magnifying glass .
... but what a potential to solve energy problems...

The succeeded on small scale, but failed on the full scale.
I cant even imagine how difficult it would be to create a large scale array that could have a focal point 50-100 yards out (if even possible).
Anyone heard of hyperbole ? if not, look it up
Even if it is not actually 5000x the suns heat, it can still burn concrete, which is pretty neat
BBC did this awhile ago, only 3500 degrees though, melts rock.

Why don't they combine this with solar cells to get higher efficiency rates?

He must mean 5000 times hotter than the sun's radiant temperature on earth. Obviously reflecting the sun's own light isn't going to make it hotter.
i love how all of you people shoot him down saying it is not this or not that.... but in any case the loudest A-holes out there are the ones who wouldnt or CANT do it for themselves (no matter how stupid or silly the project may seem). so until you make some attempt at doing anything, shut yer yap. its stupid projects like this that have led many a man to greatness.
It'll be 5000 times more powerful than the single suns influence on a target, not hotter than 5000 suns. The suns actually nearly 16million degrees centigrade at the hottest point or corona.
Plus the damage is not caused by the visable light you can see with the nornal eye, all the energy is in the ultra violet or UV range, the same energy which causes you too get sunburn or damages skincells causing cancers.
If only scientists weren't so busy with Sci-Fi, maybe people wouldn't be so busy playing high pulse poker all the time... ;-)
Not 5,000. It 50 MILLION! times the heat of the sun!!
I want to know why he had to torch his neighbors?, and beyond!
well doesn't really matter how many times more or less powerful than the sun, it's pretty damn strong to instantly start burning things up.. as soon as they're in the focal point they instantly flame on!! so imagine walking by it by mistake... lol! whoops
the sun is 15 million Celsius, est., if that thing could put out the same temp as the sun, there would be no video of stuff cooking, it would literally burn it all into ash the moment it touched, heck would prob even catch fire before it touched the beam.
The surface of the sun is about 5800K (a little more than 5500 Celcius).
Also, by "5000 more intense" he probably meant just that he amplified the intensity of the light by 5000, which makes sense. He redirected 5800 light beams (one with each mirror) onto one spot.
It works when you are at 1 foot away from it ...???
What is it good for then?
Someone needs to forward this to Mythbusters! They tried making one and failed.
Actually they used a dish just like this and burned stuff the same way. The issue is at distance its very hard. Small scale was easy.
Now try this with that dishes used in large arrays of space signal detectors. It could melt the moon.
Note to others: Light intensity doesn't = heat.
No, but if it's infrared light then it's close enough.
The radiation intensity at the focal point is ≈ 5000 time the intensity of solar radiation where the collector is placed. It's not 5000 times hotter than the sun (in the core, at the "surface", or in the corona). It won't make solar cells more efficient. It's not a revolutionary or even slightly evolutionary new device. It's a parabola with some mirrors taped to it. It's good for burning ants.
Mirror-fragments work, but polishing the surface = win.
LOL)
Attach simple optical sensors with servos to move / position the collector for optimum radiance...
Followed by affixing a prism connected to fiber-optics to the focalpoint = |>------ pew pew pew!
