PARABOLIC MIRROR VACUUM POWER Giant Adjustable Parabolic

This is a thick Mylar based parabolic mirror with a 40 inch effective area. The focal length is adjustable with vacuum power. It produces amazing optics and may be an option for a Dobsonian Telescope. The part C material is a first surface mirror on one side and second surface on the other. We coat the first surface with an enamel spray as water can remove the mirror. Once coated it is weather proof. We also use the second surface for solar. FOCAL LENGTH 5000 MM TO 8000 MM. I left this a bit baggy but with a good stretch, you can make a 15M FL.

sorrxy about the dog=C

[GREENPOWERSCIENCE]

@1357SolidGold :-( Thank you, he was a great dog. When we found him he had 2 broken legs from a car. We got him fixed in 2001 and we think the bone cancer started there.

cool idea, though for a variety of reasons it is not exactly parabolic. Next time paint the back of your bottle of water with high temp black enamel. I am sure a lot of light was passing through it.

Vacuums are very close to a parabola, the clear glass bottle has a darkened steel wool inside. This increases the surface area of the heat to the water and lessens atmospheric loss.

Hi,

Thanks alot Dan for spending some cash on the experiments for the people so see how to save the GREEN. Is million of thanks for teaching and showing other then that people may improve thier studies by looking at all this experiments and ideas. Thanks alot!

By the way, sorry to hear tha the Dog has pass away. Rest In Peace!

God Bless!

[GREENPOWERSCIENCE]

Thank you for the kind words.

[sor91]

what if you make the frame round?

[GREENPOWERSCIENCE]

@91grecsi Thank you:-) He was a good friend.

If you had an eight by five mirror how much heat could that generate? I am curious as to how much heat I can get from a thing like this.

[mjcriner2]

Love it.

speaking of drum- maybe find an old frame drum or large tambourine.

That way it will be circular, portable, and still be able to fit in a neat little case :)

@GREENPOWERSCIENCE Hello, how can you "darken" the steel wool? (and what kind of wool the best for this purpose)? Thanks for the video, its great as always!

haahaa use wd40 next time it'll take the pain away instantly it works

Super glue works well on cuts like that but you have to get it to stop bleeding and make sure it's dry.

P.S. Yes, it stings a little at first but it beats stitches and leaves far less scarring.

@GREENPOWERSCIENCE U BOIL IT! SO HE DIED!!!! >.< By the way Condolence RIP Max :(

@supersnigeln007

You are wrong. All motion is relative.

[jamiecole12]

cut looks like a sad face :(

[abobjenkins]

yeah, stan must be...GAY

[soulioman]

how is this king of mirror is called??i want to make one !
