SATELLITE DISH CONVERSION Huge Parabolic Mirror Solar Power

[outofthisswirled]

Hi Love your videos and your inventive ideas, can I ask you said it's not mylar it's? What is it please, cheers also looking forward to seeing the results.

[satguy11]

I once saw an article in Popular Science where they covered the dish in mirrors like yours. They left the arms that hold the LNB at the focal point and replaced the LNB with a collector box wich they ran water thru to make steam. They used the motor that turns the dish to track the sun using a photovotaic cell to turn the motor on and off. When the sun would hit the cell it would turn the dish until the cell was in the shade, then turn off. A solar "switch", if you will.

@satguy11 I had exactly the same Idea just last week including all the components even the photo diod as a simple switch..this is strange

[MarkSharpe123]

it sounds like everyone needs to grow up and be a little more  constructive !

[silverbird58]

dan dont let up put a reflector at top focal point and converge the beam further a 14 inch dish at top should really super heat your effort

[silverbird58]

Dan can you sell me some for my old dish

?? how much or if not where did you get it??

[whiskers123]

Any progress? Can you atleast show us a video of what you got? :)

[callmeshane303]

Spank me Dan, Spank me.

[callmeshane303]

Dan gives me a hard on.

[narcovice]

what are the fresnale lens called that have a bunch of small ones on top of one big sheet lens does it all focus one spot or 5 other spots at once

[mcgehee1980]

you should make videos in series from start to finish and number them.

[heyawhaw]

YES, PLEEEEEEASE! : )

oops ... CAPS LOCK got stuck haha ... but it serves my purpose so I leave it there!

Great videos ... I think I've seen all of them . some of them several times.

They are slightly disorganized if you haven't bookmarked them. Other than that: great job!!!

[AmeriCIA]

how much wind can that withstand?? I wouldnt think very much at all.

[mrnow]

thats what I was thinking, he should have left the mesh panels for support. The reason it was mesh instead of solid was for wind loading.

[callmeshane303]

.

"I think, I think, I think....." Who in the hell cares what you think!

Why don't you bozo's go get an engineering degree and contact the manufacturer and do some calculations - instead of sharing your idiot opinions with us all.

[razerzpeed]

What is the material for the shiny part.

where can you get it?

[frankaron]

Dan,

Whats the good word are we there yet? LOL i cant wait to see it. The one M.I.T. did is nice but much more expensive and not as easy as yours will be to build. Not to mention as green as yours is due to the recycling of the dish.

[GREENPOWERSCIENCE]

About half way, I just keep getting side tracked.

If you ever pick one up from a neighbor, DONT TAKE IT APART:-)

[frankaron]

LOL Good to hear keep at it.

Any thoughts on my storage idea?

[frankaron]

Is there a formular to figure this out? As you can guess im looking to use this as a heat source up here in the cold north.

[frankaron]

I have a set of 330 gallon oil tanks one i would like outside and one inside. The tank inside will be insulated to about r49 with foam and will have a water/oil heat exchanger. i am looking to fill the 2 tanks with oil(dow therm good to 650*) and shoot for a stored temp of 500*. My question is will a fresnel lens heat 600 gallons to about 500* in 6 hours with a spot beam. If so how many hour do you think the tank indoors will stay above 200* under no load.

[FearTurtles]

The answer really depends on how efficient your system is. 1 sq meter of sunlight has the energy to heat the water in about 4.25 hours. But that is at 100% efficiency. And that is figuring going from 200 deg to 500. Most likely you will only achieve about 35% efficiency at best. So you will need about 3 sq meters of sunlight at least. And that is insulating everything including the tank outside except for the heat points.

[frankaron]

Im not as smart as i wish i was. LOL. So let me ask this, if i can get a concentrated beam of 1500*F on my 600 gallon tank. And i fill it with 200*F water and used 9sq meters of sun to a focal point on my tank. It will take 4.25 hours to heat it to 500*F? @ 100% eff. If im at 35% 13 hours would seem more likely yes?

Thanks for your input.

[FearTurtles]

Sorry I messed something up the last time I figured this.

9 sq meters has 30600 btu's in an hour. It takes 1 btu to heat one pound of water one degree. 600 gal heated 300 degrees require 180,000 btu's to heat the water @100% efficiency. Water weighs 7.48 lb per gal.

600 * 7.48 = 4488 # of btus to raise water 1 deg.

4488 * 300 = 1346400 total btu's needed.

1346400 / 3400 = 396 Total meters of sunlight for one hour needed. / 9 = 44

[FearTurtles]

So thats 44 hours. I have no idea on what I screwed up the first time. I'm really sorry about that.

Now thats at 100%efficiency. At 35% you need around 126 hours. Wow that looks horrible.

[frankaron]

If they can heat the home with about 15-20 sq meters of tubes i wonder how long they are storing the heat for. if they are storing it at all or just using it on demand during the day. Im thinking the key to this whole thing is storage capacity even if i can get 600 gallons up to 400*F the btu draw for our 2800 sqft home is only 110,000 btu now. We have a very well insulated home with open cell foam for insulation and it keeps our house warm with very little heat.

[frankaron]

Our boiler runs about 4-5 times a day for our heat demand and dont burn much oil compaired to most homes this size. Im hoping to off set the oil by 66% or better on sunny days. Some day when i learn more about steam i would like to scale a small steam tubine for electricity to make power and heat for our house. SOme day in the future. :^)

[FearTurtles]

For domestic heat I don't thing they run the water at such a high heat level. My boiler only produces about 120 degree water. It is a on demand system. So I'm thinking that you don't need that much water that hot. Have a look at the flexable rod steam engine. With it all you need is 120 degrees as well. So lets say you heat your water to only 200 deg and allow it to drop to 120. Now your only talking an 80 degree difference. The question would be how long that will last without sunlight.

[FearTurtles]

I guess the easiest way to figure that is to determine how many BTU's your heater uses a day. That 80 degrees is your stored btu's So your heat usage can be deducted from that storage + the heat loss through the insulation. Which because you are not dealing with as high a temp that loss will be reduced.

[frankaron]

My boiler is a tankless on demand 120,000 btu unit that uses 180* water to heat our radiant heat it runs at 180* out and 70-90* back in until it has run through the whole system then its 140-160* back in. My thought is at 500* start temp my loss over 12-16 hours should only drop the overall temp down to 200-250* using the heat exchanger. Im worried about the water flashing to steam but with a 2" line in and out the water should not flash with this volume.

[callmeshane303]

95% percent of the WORLD uses metric.

"Golly Jim Bob, how many gills to a hawgs head?"

Retarded Americans.

[zyxwvutsrqponmlkh]

Seeing as how America is more than 5% of the global population you must be an idiot.

[callmeshane303]

And just how did you measure the number, with board feet or by dry bushels?

[BloodTar]

callmeshane303 . . .

95% of the world is envious of America.

[callmeshane303]

Yes that's true, so much so that they even have the same flag as yours, only theirs is on fire.

[BloodTar]

Still doesn't cover up their envy. I win, you lose.

[callmeshane303]

Ummmmm Ok so you say "I win"....

Ummmmmm who allocated you the winner? (first question) and

Exactly what is it that you won? (second question).

It sounds to me like by having sex with yourself, you got yourself pregnant.

QED. OK - so you win.

[latrans67]

Be Specific Shane, are we converting UK units, US units, or from one to the other?

[callmeshane303]

Since when did you and your 8th grade dropout bullshit; become "WE".

[latrans67]

Is that the very best you can come up with? At least make your insults more intelligent than what one might hear in elementary school... or you might try the novel approach of crawling back under your rock like a bug.

[latrans67]

Ok, I get that you have self esteem issues and you feel that by insulting others you somehow make up for inadequacies. This being said, if you act like a troll everyone will treat you like one. If you are unable to be civil I would prefer you simply not respond to me or anyone for that matter... and since you do not know me you have no idea of my educational level. So, in summation, please cease and desist if you are unable to hold a conversation with some level of intelligence.

[callmeshane303]

.

Yeah your right - your so completely right;

But I still don't understand you.

[FearTurtles]

As for the heat loss of the tank under no load. The problem with figuring that out is that the internal temp is not a constant and you don't have an internal temp. You have greater heat loss when the inside and outside temps very greatly. So your actual loss would be on a curve. Also on my previous comment is with using water and not oil. You would need to know how many BTU's it takes to heat one pound of oil, one degree. 1 sq meter of sunlight in 1 hr has 3400 btu's At 100% efficiency.

[frankaron]

Thats a lot longer then a day. I have an acre of land set aside for this project but i want it to be something the average homeowner could build and use. Im thinking in order to harness the sq meters needed to heat the oil in a 5-7 hour time frame i will need about 100 sq meters of sun which is a lot. What variable can off set the 1* per pound per hour in a positive way? I see many home with evacuated tubes and they use them to heat domestic water and some use them to heat the home.

[frankaron]

Dan*

Sorry

[GREENPOWERSCIENCE]

Hi Frankaron,

Sorry about the vanishing idea, not sure why:-(

Please feel free to post your ideas. Also, my website has an email link for you. Greenpowerscience com

[frankaron]

Great idea i have been wanting to do this for quite a while with lexan. I cant wait to see it finished.

Don,

I have an idea i have tried to share with you on here twice now but for some reason it keeps vanishing. Is there another way to contact you?

[ronnienorth]

Awesome!! I just picked up a giant dish like this from my local craiglist free section. I'll be following along! Please share any info you can, it'll help me a bunch. I bought one of your 25" dishes from Ebay, and it is powerful, so I can only imagine what this thing will do.

Thanks!!!

[GREENPOWERSCIENCE]

Hi,

I have about 50 Rolls of the Liner. A Dish this size requires 2 full rolls. Cutting them is a bit of a trick and once I am done, I will share what I learned. All the materials will be on my website soon.

[Anothercoilgun]

I cannot wait to see the completion of this project. I want to see this coupled to a SES type of stirling engine and the number for the KW electrical output.

[danz409]

oh.. my... god... this thing will be signaling other planets with its massive reflective properties. people in other galaxies will look twards us and see something sparking. "hey that star is about to die" only to be blinded by a death ray of sunlight shortly after. LOL

but honestly. i belave this thing will be visible with the naked eye from space

[equipmentandtrucks]

You always have great videos.. Great work.

Oh and your wife is HOTTER then that Parabolic Mirror !!

[Punishment7]

be fun to see this one. I have a fresnel lens that I bouthg from you, and was thinking if there is possible to combine them? Or will the fresnel lens take all the sunlight and block it from the parabol sun collector? Also I tried to figure out wich of the 2 are most effective, fresnel og parabolic solar collector? Do you have any ideas of that?

[GREENPOWERSCIENCE]

They can be used together BIG DISH. Normally anything you place in front of the dish takes the sunlight so you end up with a net zero. but, the center of the dish is blocked by the target (water tank....? etc.) . Also the center of the dish does not do much so it will help in some cases.

A Spot Fresnel and a Parabolic mirror are the same size for size but the Fresnel Lens will usually have better optics so the Fresnel edges by about 10%.

[GREENPOWERSCIENCE]

If your target is larger, it blocks the mirror so you either have to angle the mirror or allow it to block a bit which lessens the power.

For smaller mirrors 35" and below, you can combine like this v=U6294LKoU5M

[tinkergalloot]

looking forward to seeing this built and the max temp at the focal superheat steam? keep the videos coming dan i spend more time on your channel than all others combined thanks for great info

[Odziz]

Mmmmm, Solar Death Ray, nice!

Reminds me of the Light Sharpener project on YouTube.

watch?v=DdrufLhHPJw

[GREENPOWERSCIENCE]

Hi Odziz:-)

Lightsharpener was a bunch of small mirrors. This should be a lot stronger. I was able to burn wood today with 2 of 18 panels in place. The screens actually are edge curved. That means this is a true parabolic not array flat plane.

Putting it back together was a tough job.

[Odziz]

Yes I realise that they used small mirrors.

What I meant was that when you were building it, it looked the same type of dish with the arms and mesh sections.

[GREENPOWERSCIENCE]

Hi Odziz,

His dish has a round rim. I wonder if he made it from scratch?

[gug1970]

Pity any birds that fly through its focal point.

Cooked before it hits the deck i reckon !

[gonzon22]

I live in Tampa bay too and the weather has been really crummy lately. I was hoping you had the dish up and going but I know its a process. In this months Popular Mechanics they have an article you mite be interested in. It's about sterling engines attached to reflective dishes that are more efficient than any other solar device. Thought it would be cool to see what results you get if you tried it. Just a thought. Take care and Go Rays.

[phoenixar]

you rock!

[naisayd]

Thanks Dan. This is going to be the hottest one yet. It would also be nice to know a bit more about the trough liner. Like who the manufacturer is, where do you get it from etc.

Thanks

[roidroid]

agreed. I'd like to know what to google to find this stuff.

[GREENPOWERSCIENCE]

Hi Roidroid,

What material, the liner?

[roidroid]

Yes the liner.

[slowlyawakening]

I want your stuff! You make all of these awesome projects.

[ohmslaw111]

You have a cool toy chest of science things.

[LinuxUser269]

thanks again dan.....great job!

[pubtor]

such a big dish! are u going to shoot down ufos?

[GREENPOWERSCIENCE]

ET has it coming:-)

[fakemjk]

Fantastic job!

[sonofhendrix]

Great.

[dannyknapp]

wow, that's gonna be a monster !

[BILLNYYE]

Thank you for the mirror vs mylar info always curious.

[ALTERNATIVEENERGYDRI]

Got it next week. Where do I get the "trough liner"?

[ALTERNATIVEENERGYDRI]

Damn, what a great concept. I was thinking of the broken mirror trick. This looks amazing. When will it be done?

[ChappaMan17]

cool
