@kaje01 but surely you could make the panel smaller as the light would be concentrated thus meaning more light is hitting the panels in a smaller area than over a larger area?
I have a question, could a lens like that be used in conjunction with a solar panel to gather more energy than using a solar panel the regular way? Would the solar panel be destroyed or would it generate more energy as the light is more concentrated?
Where and how did you get that cool mirror
also how much 
I don’t think that is fair, that looks like a two piece telescope mirror. The large mirror that is. There should be a small mirror facing that big mirror shooting the light through the hole.
Hey!
I got one of those $14 telescopes!
Not too bad for looking at the moon for the price. IMHO those would make a decent inexpensive spotter apparatus.
fresnel |ˈfreznəl; frāˈnel| (also fresnel lens)
noun Photography
a flat lens made of a number of concentric rings, to reduce spherical aberration.
ORIGIN mid 19th cent.: named after A. J. Fresnel .
Sorry dude. Didn’t mean to be an ass. I guess both are okay.
@Jarathe
pronounced /freɪˈnɛl/ fray-NELL
I love your videos dude, but it’s freSnel lens; not frenel lens.
why NO closed captioned in here video

0.o thahts awsome wehr did you get it ? probably you did the deal of yor life or this isnt actualy an real teleskope mirior (maybe it has some kind of an extrem destortion you wont even notice for such an use(telescope miriors have to be precicse to the scale of some nanometers))
Thats a kick ass schmidt cassegrain I would make a very nice scope with that . Someone stold my Mead 10 ” LX5 freaking thieves I hate them .
It is nearly perfect, there are some very very minor scuffs, I got all the finger prints off of it. This was for sale as a scrap item for $79:-)
wtf ??? whre did you ge this hughe telescope mirrir and do you have any idea what such an miror is worth ? it hurts me to see it being used as an sun colector (i hope something is badly wrong with this mirror so it couldnt be used for an telescope anyway)
Maybe the stars won’t go away Lashon3D.
Thank you for the great information. I will add this in annotations. I figured that was what it was for. Thank you for all the info:-)
Kind Regards
Dan
That telescope mirror may have a short focal length but it is meant to be coupled with a convex secondary mirror which yields a long focal length in whats called the cassagrain design. The hole in the center is where the light goes after the light bounces aff the secondary and the image would be formed behind the main mirror. I’m guessing the mirror came from either a Meade or Celestron “Schmidt-Cassagrain” telescope. What a shame. These are excellent telescopes.
Dan & Denise should have a science show on TV!
I’m a little jealous at the size of your lens. Juss saying. I can’t find a page magnifyier, let alon esomething of that size
y duz the mirror have a hole in the middle?
watched part 2 learning more Thanks!
Cheers

I think the main point here is that it’s not how focused you can get the light, but rather how much total light you can get to hit your panels. Maybe if you were using steam then it might be more important to have a hotter focal point.
Have you thought about going into business building these things for people and getting them off the grid? If you could install a setup like that for say $10k, you could finance over 5 years and the consumer would basically get it for free.
cool thanx man
