PARABOLIC DISH MIRROR REFLECTOR SPHERICAL SUN PARABOLIC SOLAR COOKER REFLECTIVE ALUMINUM

[Ariffinhb]

Hello, I am interesred in your parabolic reflector.How much it cost?Email me at Ariffinhb@yahoo.com

[snocamo154]

I took the 8 inch reflector off an old million watt search light and it made a useful firestarter. Dried broomstraw literally exploded with a pop before igniting into a useful fire.

can i get this metal aluminum sheeting at home depot or lowes? how much? and a 12 inch dish preferably? all used hopefully & i'm interested in adding an enclosed thermocouple at the focal point to make some electricity.

this song is good to light up some joints on thouse mirrors :)

[moneyngod]

what song is that? title please

[GREENPOWERSCIENCE]

Sandkirt I mixed, I have a Mp4 I made, email me and I can send it to you, 2 min long.

@GREENPOWERSCIENCE You should use silver not Aluminum because Aluminum causes Alzheimer's disease, wake up or you are telling people to poison them-selfs, and that is why Aluminum was banned before,

@SpaceMan131326 AT LEAST YOU WON'T REMEMBER IF YOU HAVE IT...

It does work in winter time. In fact it work rather well because the sun is closer to the earth than in summer, and on clear days the skies have less humidity in them.

[enicao]

that's wrong, the difference in heat between summer and winter is due to the change in the inclination of the rotation axis of the earth.

in summer the sun is higher is the sky, so there is more energy per horizontal area, and the sun light as a shorter distance to go through the atmosphere.

in winter the sun is lower, so there is less energy per horizontal area, and the sun light as a longer distance to go through the atmosphere

same as midday sun is brighter than just before sunset

[seancap08]

then why are concentrated temperatures just as easy to obtain? by your logic they should be more difficult but this is not the case. 900 and 1000+ degrees are a simple matter in winter with ambient temps 30F and below on sunny days.

[seancap08]

...by aiming the dish though a more clear atmosphere while the sun is closer you negate the claim of "higher in the sky" regardless of the tilt of the earth, the energy at the focal point of the dish is what matters. Energy is focused through a straight line, from a straight line, to a focal point - regardless of ambient temperature. The horizontal captured area is only that of the dish... and its inclinication is designated by that of the season. - you are wrong!!

[seancap08]

You also forget the effects of entropy in that of rocks water and soil. - they hold the heat in the capacitor that is the earth. I'm only focusing 32 sq feet on direct angles in the cold - while the sun is closer.

[YourMom4free]

Do know if this would work in the winter time?

[telewebservices]

Just don't release those monsters into nature, this can easily cause fires world wide.

Nice job with the 23" spherical reflector. I assume that is the one you molded in fiberglass from the bottom of a water tank?

Did you know you can get page magnifier Fresnel lenses at Walmart? I found them next to the optometrist area for about $12 and the lens measures about 6.25"x9.5" which is equivalent to about 40 watts of sunlight. Much smaller than what you use in your videos, but great for lighting fireworks, making fire and such. It is the point focus type rather than linear.

[MrfixitRick]

Ok GreenScience, you guys are pushing it...I just realized I just watched a movie with no words and no actors and loved every minute!

The cool soundtrack did it...plus it's really fun to see wood burn from power collected from the sun.

[silverbird58]

but hey gotta watch the buget

[cdltpx]

Sure you can do that to your taters but doing it solar is great becasue you get home and you don't ahve to wait lil sour cream some cheese chives gravy from a roast and you are dining within your arriving home of 5 min.

[roidroid]

your big dish has a rather slight curve but it's still surpruising how close it's focal length is.

it seems that if you want to focus onto something a few meters away, one only needs an ever-so-slight curve. Perhaps just a normal flat panel of something - with a slight vacuum behind it will provide enough curvature.

I wonder if a large flat GLASS mirror will be able to be tensioned like hat and not break. Perhaps it is possible.

[BILLNYYE]

Do you like spherical shapes or true paraboloids for solar use.

[BILLNYYE]

Where can I get an aluminum bowl?

[solardeathraysun]

can you line one of the aluminium dishes with the mirrored stuff. like the 95% only?????

[GREENPOWERSCIENCE]

Yes, I am lining one now. It works perfect. Except for a few bubbles.

[JULYINJULY]

NICE MUSIC!

[ALTERNATIVEENERGYDRI]

I want one?

[Snapshotok2000]

This is interesting !

I just happened to find an old bowl-shaped steel bell. The part that gets struck by the hammer. I was going to cut it up to make plates for my hho tank. But I think i'll use it as a solar stove.

[linutas]

cool how i can make one?

[sciencefun127]

I think it requires metal turning

[sciencefun127]

to make the aluminum dish.

[JavaLessons]

Apt music.

People of India, the power is yours !

[GREENPOWERSCIENCE]

:-) Day off sounds good. That is a great idea, I see chip companies migrating towards solar potato chips. But I think they just use solar panels to aid in the normal process.

[cdltpx]

I saw a guy make an oven out of a metal bath tub he used a cardboard box as a reflector and would bake many loaves of bread at a time but the same could be done with taters I bet someone could start a business with this method selling solar baked taters a truly green company low overhead the ovens would be recycled tubs painted black they could cook roast and gravy,chicken and gravy something great to eat with baked taters. No sun take the day off.

[roidroid]

what's taters aye?

[cdltpx]

You know potaters them things we turn in to french fries taters. Like if you eatin some alligator and french fries you are having gators and taters.

[roidroid]

boil em, mash em, stick em in a stew?

watch?v=BV3GxS2mQfs

[Vintabilly]

Potato cut into wedges, dipped into spices, and thrown in a deep fryer!

Yummy with ketchup and salt in a paper bag from the local Quickie-Mart!
