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
[citation][nom]oxxfatelostxxo[/nom]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.[/citation]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.

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.
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.
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!
(only needing a way to shut it off LOL)
This is pretty sad, and a quite lame.
Not sure why you would go through the trouble of tiny mirrors which are obviously out of focus. The focal point is more like a golf ball in this vid. What you need is a parabolic dish mirror.
Oh yeah and guy obviously means 5000 times the light of sun (in focal point, or focal golf ball) as compared to 1x light of the sun on your skin under normal sunlight. This would be erroneous as the mirror does not reflect all sunlight.
There was a program on TV recently where they had a huge parabolic dish mirror that could melt a large block of steel in a matter of seconds but the focal point was about 4 meters from the center and the guy had to wear protective gear as a drop might kill you.
Depending on the size of the mirror and the focal point you could actually create a small point in 3D space where there would be millions of lighrays. Why go with millions, when you go with BILLLIOONS. *Raises pinky to mouth.*
