HUGE PARABOLIC MIRROR SOLAR POWERED SUN COLLECTOR solar energy

[loveelsanow]

Sorry，I have question。Where can i buy like this PARABOLIC MIRROR??? THX~

[MrBrunosp]

It is possible to heat the pool water?

[PBaober]

ive got a 65" military surplus parabolic dish in my back yard:) the coating needs some heavy buffing though:/

[PBaober]

@PBaober **65" in diameter not circumference



[Marco9641]

Dan, is it possible make a cossegrain telescope wih this parabolic mirror?

[Lupercalia1]

Ottimo per difendersi dagli alieni nazisti ahahahhahahaha

[honeybunchickens]

Where can I get a mirror like that ?

[GREENPOWERSCIENCE]

@honeybunchickens Check our site, there are links.

[fatmanplaying]

What would you use this for?

Please don't say burning ants! 0.o

[Evi1M4chine]

Huge?? If it were 25 meters, I’d call it somewhere between large and huge. 100m is huge. 25" is between small and tiny!

[junkyardnut]

@Evi1M4chine we really have very little uses for parabolics.. Flat mirrors will do as long as you multiply them at different slight angles toward one target where you can collect them all for heating air to heat your indoors. Why we dont have them yet... ????

[NanetteW]

are these chromed, please?

[fullrokr]

how do you make the dish have a chrome finish?

if I use a reflecting paint will have the same bright?

[Dalophax]

-Dan, would silver paint and aluminum cans work just as well as a mirror?

-Good vids.

-Have you ever roasted marshmellows with that?yummy!

[GREENPOWERSCIENCE]

Hi,

They will work but only about 40% of this.

[luc59457]

That is super reflective! Mine takes a bit longer to burn things but I already cooked some eggs with it =)

[junkyardnut]

@luc59457 solar egghead!!

[luc59457]

@junkyardnut naw, unfortunately, I'm not 100% solar egghead. I'm more like you, a Nuclear egghead. But given your area, you could very well be a coal-egghead lol.

[cabesa88]

Thanks for the video but it needs more information, like what materials to use and specially no toxic elements please! and of course take care.

[9ijklk]

Hi, Dan! I cannot hear the audio on this one ... except it seems to cut in for a moment just before the text on the screen which states "50% of mirror blocked by tree shadow" or something quite similar. Can you add it back in? Warmest regards, bro. Rob [from the Shenandoah Valley of Virginia]...

[Drumvain]

I am not clear on how you harness the energy.

[sarcasmo57]

Be careful too many ultra violet rays from the sun can give you cancer.

[vnnycnt]

How does the intensity of the energy change as you move closer to the focal point? I'm guessing it's fairly rapid and sudden if you can put your hand so close to the same point that lit a stick on fire. In other words, as you move your hand along a straight path that crosses the focal point, when will you experience intolerable pain?

[GREENPOWERSCIENCE]

Yes, This mirror can melt black plastic at night concentrating light by a high intensity flashlight that is 30 feet away. It actually starts to burn.

[junkyardnut]

@GREENPOWERSCIENCE never thought of that coming from a damn flashlight! Photons is something , aint ?? Hey, I was wondering about the abillity to transport hot desert sunlight over fiber opitics to ski resorts where you got fiber optic powered furnace to keep warm without any need for firewood that pollute the nice mountain air you alwasy crave to breath only to be interrupted by lingering smoke !! cough cough... anyway I wonder if fiberoptics is tough enough ???

[inthefade]

if it is parabolic, if you put the camera lens at the focal point, shouldn't you only see the camera reflected? Not that it matters, I'm just so impressed. What a cool toy.

[joshig1983]

Put the camera in the centre of a spherical mirror and it'll see a reflection of itself in all directions. Put the camera in the focal point of a parabola and it'll see the colour of wherever the mirror is aimed across the whole surface because all rays from the focal point are reflected parallel. Assuming it was perfectly parabolic, you could remove all the lenses of a camera and take photos relying on the mirror as a huge lens. It wouldn't be accurate enough for that, though.

[TheMojoTribe]

armatures!!... joking lol nice one

[GREENPOWERSCIENCE]

:-)

[pubtor]

more interesting clips pls!

[JERRRRRRY1976]

Hey Dan,

Acrylic mirror sheets (or plexiglass) is a good material for your experiments, its VERY flexible, reflective and big.

You can make a water heater by making a

U-tube mirror and black hoses. The U tube can be as long as you want because you can join several mirrors, or make an array of mirrors and making a heating circuit with the hoses.

Cool site!

[GREENPOWERSCIENCE]

I have seen sheets up to 4x8. What is the largest you have seen.

[JERRRRRRY1976]

Hey Dan,

What about taking a parabolic antenna (a fiber glass one) and covering it with mylar even if mylar is not as efficient as glass the size could make the difference.

Other way I thing is to get some parabolic antennas made form steel and get them to chrome in a chroming shop.

DONT TAKE TOO LONG WITH THE REAL VIDEO...

[GREENPOWERSCIENCE]

The new video is out and I have a 35" mirror on the way. I will have videos on all the parabolic shapes. We finally have good sun after a horrible 87 day summer of almost zero. Sun shine state LOL. Sorry for the video delays. We are working on 6 different ones right now. If all goes well we are hoping to squeeze out 20 in October:-0 I hope.

[GREENPOWERSCIENCE]

Hi Jerrry,

The chrome is a great idea, just expensive. Steel dishes have this non-stick surface like teflon. Nothing sticks to it. I am sanding one now. I just got (2) 36" dishes. The coating is the part A and B from my other video

v=FZh-CRneIII

There is a spray that costs $40 a can but requires another $40 can to base coat and another $20 can to clear. Not sure if the coverage would be worth it. There is also a 2 part spray system that costs $1800. The process seems toxic.

[starwolf72]

same here dan more info please and more video more often.

[kardel100]

Hi dan, as i have been unable to by a mirror like yours my brother suggested i mark out the parabolic shape on wood, dig a pit, fill it with sand, use the shaped wood to scribe a perfect parabolic shape, (carefully) fill the sand with cement, then remove the set cement and smooth the surface with fillers to make a perfect parabolic mold from which your can make as many mirrors as you like! remember d bigger the sand pit d bigger the mold and mirrors! regards Derek. looking forward to next video

[Unguidedone]

the mold need to spin and the mirror needs to cool while spinning for a good mirror.

[GREENPOWERSCIENCE]

That is the process I was thinking of too. I think moving a half of a yard of cement might be tricky..... unless you have some help. I bought an 8' beach ball, I will be trying to make a spherical shaped mold off of that. This thing is a monster and goes where ever it wants with a bit of wind. Requires a leash.

NEW VIDEO on the mirror.

[darkvader47]

C'mon Dan, you we're all I'm spoiled by your audio teaching. You get a bye this time. I'll be waiting for your real video.

[GREENPOWERSCIENCE]

Yes, I will have the full video soon. This thing just looks so amazing, like looking at a real life special effect filter.
