maybe you could make a heat exchanger based on oil. a little black container in the focal point with tubes running down to a cooker plate. either an electric pump or one based on a small stirling motor to circulate the oil. the dish could be tracking. that way it's easier to cook
I might be wrong, but I don't believe that the direct tv dishes are parabolic. They're designed to receive at an angle, and reflect to a spot at another angle. Using it straight on will probably give you a spread out heating spot.
I have watched many of your films and you guys do a great job at explaining things to us all. You make us think a bit and that is good .
My biggest question is WHAT reflective film product out there is the most effective or is it reflective ,is U.V. stable and will last for perhaps decades WITHOUT peeling and coming off the surfaces in which it is applied?
There are lots of products out there and most of the ones that I have seen do not last long.

Can some one give me some tips, first ive got a slightly oval 18" by 22'' dish to make a mirror , is the dish satellite oval dishes still a good mirror to use ? do they focus like a true parabolic mirror once linned with reflective foil ? ?
If you're thinking about getting direct TV you should know Ga rewards gives you insane incentives for it, like 8000 microsoft points, 2 years of xbox live, turtle beach headsets, gunnar eyewear, if you and someone else signed up you get a 360 slim, ps3 items too, click my name and watch the video for more information
Question couldn't it be just as easy to pay and have something like that caromed? It would be shinny all over and it in my mind would make a good parabolic mirror. But i could be wrong i dont know ive always wanted to make one of those.
can i just ask a question, i really don't understand wth is that :) BUT can i line the cardboard made dish with aluminum and use as a portable dish at home? (of course i will use a receiver and an LNB
ok your name is greenpowerscience but for those who has a neuron in brain please make a video with a simple solution to get energy with simple materials explain it step bye step hehe sorry if i sound very stupid but a friend told me to ask u for a video like the one i am asking hehe he does not understand how to assembly your ideas hahaha
You are so awesome! I really want to make a couple of collecters and I have 2 old TV dishes I want to use. What is the best material to use for the mirror? I would like to use them for cooking? Am I outta my tree or is it possible?
ok them emergency blanket are mylar. to make a sun tracker get 2 big soda bottles 2 pullys on the back side right and left at top put a pully try a string to the middle 2 of them going over thr pully then down to bottle tie on full with water one has a pin hole at bottom as it empty the heavy will pull the dish to flower the sun will need a lady sueson that thing in your carboard that turns lol
wondering just how many uses, (average home uses) does this thing have. I mean; other than the sterling motor, can I use it for? I guess I cant directly point this thing at my solar can heater??? It'd be too hot, corect?
Dan, did you ever get this large parabolic mirror finished? It certainly would be almost dangerous to use. With part A and part B mirror, you could weld metals!
Dan, love your stuff. Just a note on safety though. I have a friend that did a lot of solar experiments in the early 80's and he has some significant loss in vision because of damage done by looking at various solar experiments he was working on. I have seen you use goggles before (and assume you use them pretty regularly) but I didn't see any in this video and I worry because I want you to keep up the great work.
There's a very cool iPhone app called Satellite Augmented Reality. It has a database of over 370 geo sats and lets you view where they are in the sky. It also calculates the azimuth and elevation angles for you based on your location. In addition, it lets you enter a virtual location in order to see what the satellite view would be in, say China, if you are in the US.
i wonder if, one could place a fresnel lens at a certain vector along the arc of focal points, that would focus the light, even more so than the reflectors did by themselves?
Why would you want to? Are you thinking of a d"death Ray" device. Other than creating a straight beam of light (energy) ( To create a truly straight beam that would hold together for any distance you would need an array of lenses, very precisely calculated and mounted, probably easier to build a laser), The dish has a focal point, hard to improve on a pt.
death rays are the furtherest thing from my mind. what i'm thking is, with reflective points, fixed... mounted in say a hill side, all focused at a single point, then all one would have to do would be to put a closed water source at that point also, then hook that up to a steam turbine, or even an old steam locomotive engine (piston), hooked to a generator and have a steady, virtualy free source of electricity.
Actually, you place the steam generator ( boiler, coil, whatever )at the focal point of the dish connected by a flexible coupling ( stainless reinforces high pressure hose) then to you turbine or sterling engine. The "cost " would be maintenance on the system, plus just a bit to power the tracking motors). If you live in a climate with enough clear sunny days, go for it, the payback may be long, but properly designed it will work.
What if, by using a fresnel lens, you channel the light just off the focal point into a straight beam. I was thinking of taking that beam down a solar chimney of a sort to use for indoor cooking. if the diameter of the parabolic mirror is 5m(16.4ft), can i then take that light channeled down, and split it into 4 parts and still have enough light to heat 4 stoves?(The stoves using either the solar cooker method or fresnel lenses reflected up onto a large pan). *the chimney = 5m height max.
Difficult. The parabolic dish needs to track the sun, and do to the nature of fresnel lenses I believe that this beam would be sent along the axis of the dish, right back toward the sun . therefore you would need a series of tracking mirrors to aim this beam to you stove ( As the dish is tracking the sun, the "aim" of this beam would be constantly moving)
yes; parabolic dishes, have always been my tendency. I was thinking arrange them in an arc that follows the sun, say in a hillside, mounted in concrete, such that at a certain place, for the better part of the day, you had that one or two k fahrenheit temp. no need to devise a tracking mechanism, once everything was in place, if the sun was shining, you have the energy there in that place.
This comment has received too many negative votesshow
Whenever I see the words "free energy" and "stirling engine", your credibility goes down to zero. Why don't you just come out and say "perpetual motion".
The sun is providing free energy. So the claim is obviously valid.
A sterling engine is also a scientifically proven engine that was used in submarines and ships.
Perpetual motion is also theoretically possible. Our earth moves around the sun perpetually. Therefore it is in perpetual motion (unless of course something stops its motion around the sun).
Read some books, get a good education, listen to your teacher and then come back and comment.
Perpetual Motion and Free energy are totally different. Free energy is hot water on a garden hose. Light in your house during the day from the sun, a cool breeze lowering your AC thermostat. Natural forces are free in comparison TO PAID UTILITIES or burning wood for cooking.
All things cost money to keep working so I guess nothing is truly FREE. LOL
But, when my Stirling Engine is running off of the sun, FREE:-)
Since you made this post have you seen the sterling engines that they are driving small generators with. They seem to be doing pretty well. I can find the site if you are interested.
AfroSheen Wow that takes me back, remember the commercials?
Dan, you said in video that you had PI shaped templates on your site but I found none. There is no downloads link and under the building a parabola link, there is also nothing.
Dan have you tried making a dish out of your solar reflective film and gauging the effectivness between that and a "proper" one. Stretch some film over the end of a barrel then suck the air out of the barrel. As the vacuum pulls the film tight it forms a pretty perfect parabolic dish. I haven't played with a proper mirror dish but would like to know the comparisons. Thanks for the video
@silverbird58 I am a ham of 31 years. The code literally translates as jibberish "BC TA0WBC 0" and I doubt would be considered as valid code groups. Code groups for radioteletype tests as the FCC gave, included 5 character groupings which could include letters, numbers (such as the zero heard twice), and up to around a dozen punctuation symbols, such as , . ? " / and a few more.
greg357159, - easy, satelite dishes are focused on the existing LNB, (the arm with the "eye" on it that recieves the signal), is perfectly focused...personnally I would replace the LNB with a small boiler to power a small steam engine...this would work great with the old C-Band dishes.
How rude, Spike. Dan is simply experimenting in his backyard and telling us about it. He never claims to be more of an "expert" on any of this than anyone else. He just has the generousity to take the time to film it and then share it here for FREE with all of us. Get some gratitude. If you don't appreciate the videos then DON'T watch them. I could make assumptions of your education level based on your lack of grammer and punctuation but I won't. There is no need for hurtful comments. Dan U Rock
@Alexgone You made a great point there about gratitude, but then you spelled the word 'grammar' incorrectly. Why do I see this same spelling mistake occur whenever two Youtubers begin arguing about their "education levels"? Wouldn't it make sense to proof-read your reply before posting a criticism? Btw, 'generosity' doesn't have a 'u' in it either. I try my best to resist dumbing myself down by reading and replying to user comments... I'll try again tomorrow. :(
i think it's quite possible that one day you would fry your receiver doing that. If the sun comes at least close to the possition of the satellite you're picking up - guess where your focal point will be :)
Hi Greenpower , It is really great to exchange the ideas. I am quite entusiastic about finding the alternatives. And your videos are really nice. My suggestion is - why not use few more of more dishes aligned in the circle to the same focal point. This way, may be we will not need a sun tracker so much
About the time it entered my mind as to go about finding out how create templates to make a "pie shaped" petal parabolic dish Dan mention he would be putting up the templates on his web site. I have it open in another tab, but no luck in locating them, any hints please?
there are tracking system available , just search for 'olar tracking equipment" in internet surely you will find some website , however this paraabloc dish can be used for heating water during day , if you make some arrangement to hang a wsmall copper cyclinder which is colored black, and make water circulating arrangement to that copper cylinder , you can use very chip water pump with very less wattage to circulate water and store into the your water heater tank, of course need control systems
With all of the planes and helicopters that fly over your place, youre going to take one of them out of the sky one of these days, with all of those mirrors. hehehe
The light spreads out again after it passes the focal point. If he held that piece of wood just a few feet further away from the mirror he wouldn't be able to light it.
current status? Anyone here use .080" thick mirror acrylic sheets? Starting 10ft dish project....anyones feedback would be great! Nice video's, you need a show on Discovery / TLC .....or similar
I did a 12 foot fiberglass dish using glass mirrors. I'm not sure if the acrylic will hold up in the sun, because the sun attacks and degrades every plastic that I've ever heard of.
now if you started reading this dont stop its really scary!ok send this to five other videos in 143 minutes. when you are done press F6 and your crushes name will appear on the screen in big letters this is weird because it does work. If you break this chance you wont have a crush in the next five years
So what is the practical application of the parabolic mirror? It's a great parlor trick to light a stick but is there anything of a more useful nature that can be done? Thanks for your answer.
Hi Would it need a tracking system to work along the solar movement of the day or if you leave it in a certain position, it would focus more or less heat on the focal point? Im just trying not to mess with tracking devices...
GREENPOWERSCIENCE, shouldn't you be wearing eye protection if you're going to view it burning up that close? I suggest you check up on that. I don't know if it really matters, but I think I read it can be dangerous.
IGOOD ADVICE. Its very tempting to look directly at the sun when trying to align the parabloica. Brilliant vid by the way; next time wear please some sunglasses. Thank you
what i meant is that i also have to make a parabolic solar grill. the firs part the equations are 60 pts, a research is 20pts and bilt the solar grill is 20pts. can somebody help me with this
i have project to do for my math class. she gave us some equations, like xsqare=2y, (-3,4.5), find the tangent line x intercepts then graph quadratic equation and tangent line. 9xsqare+24xy+16ysqare+80x-60y=0. she also gave us r=4/1+sin ( ). can somebody help me with this or give me some ideas or websites thanks.
I'm not sure why he hasn't directly responded to requests for information about the mirror film, other than simply trying to protect his market?
I'm not sure exactly what he's using, but I know a material called ReflecTech will do the same job and I think already has the adhesive on the back too.
The manufacturer's site sells it, but the smallest quantity is 150 sq ft. I also found a site which sells smaller quantities. It's expensive though.
We have a satellite dish exactly like that. What is that reflective material that you're using on yours and where could we find some? Any details on price and availability would be helpful.
I will have some on my website soon. A large 4' x 8' section costs about $150. It is thick like a business card and 95%+ perfect mirror. The back side needs adhesive. I use a 3M mounting spray. I had to make some adjustments and the video will be out soon. Material on our website in a few.
I polished a 7' aluminum dish, it wasnt nearly as reflective as the mylar. That thing was HOT. It would boil a coffee can of water rather quickly. I never got to the main idea- power a steam engine with it. Is there a way to figure how much power would be available with , say, my 7' dish?
You can get Aluminum to 90+ if you have the time and the right buffer and paste. I have seen trucks with doors that are amazing.
You have about 36 + sq ft roughly 3500 watts of heat energy at 100+ reflectiveness. If you have a 70% mirror, you are 2500 watts roughly. You would need yo take 25% of the figure for efficiency loss engine boiler generator converter. 2500 x .25=625 watts in a good scenario.
Are you still pursuing this dish? I want to see how far along you have come with this one. I mean, this is the only video that I am actually tracking from your collection. Show me the burny!!
I wish I would find one of those 35 inch dishes cool. I have two 20x22 inch dishes I lined one with mirror on a roll that I bought and it kicks ass pops flames on wood instant. I also made a dish from that one before lining using plexiglas and heated in the oven at 250f like one of your videos instructed that came out ok also. I am going to make a linear parabolid next. thanks for the tips.
dam im seing triplets.lol hey does tin fil work the same way or dose it have to be pure shiny metal for the effect. a magnified mirror burned my dam hand
The Mother Earth News has an article in their Dec 2007 issue titled Solar Heating Plan for Any Home. This uses a flat panel drain back collector and a 500 gallon tank of water for thermal storage. The heat is then piped to an in floor radiant heating system. I wonder how a parabolic like this or the trough one from your earlier video would do in place of the flat panel.
Hey, don't you think it would have been a smart idea TO MENTION WHAT REFLECTIVE MATERIAL YOU USED! Man, how could you possibly leave out something that important!
Just got done building my 8 ft dish lined with acrylic mirrors, made from old satellite dish, but now I need something to have it track the sun. Any suggestions?
Great work! I'm planning to make a parabolic mirror from a fiberglass satellite dish, but want to do it as low cost as possible. Would aluminum foil (shiny side out) secured with spray on glue be an adequate (if not equivalent) substitute?
You could strip the coating off of the dish and polish it to achieve a mirror finish without having to add any other materials. You coule achieve a much higher quality finish. Thanx for the videos.
You could make a steam generator to provide power and heat your home also all the hot water you need almost instantly. Every home should have a solar generating plant if anything for the times the power goes out for whatever reason.
Strange coincidence. I bought an 8' dish two days before your first vid about your big dish for the same reason. I bought your 65" fresnel a couple weeks ago, and it's AWEsome. But I've got the bug now ... need ... more ... power ... danny! Not sure what I'm gonna do with mine :) I guess I should put the mylar on it first. That'll take a while.
The guy I bought it from makes his own deisel from waste cooking oil and cools his house with a waste motor oil powered heat exchange system.
maybe you could make a heat exchanger based on oil. a little black container in the focal point with tubes running down to a cooker plate. either an electric pump or one based on a small stirling motor to circulate the oil. the dish could be tracking. that way it's easier to cook

Perpetual motion is also theoretically possible. Our earth moves around the sun perpetually. Therefore it is in perpetual motion (unless of course something stops its motion around the sun).
Read some books, get a good education, listen to your teacher and then come back and comment.
LOLDISNEYLAND 2 years ago
Perpetual Motion and Free energy are totally different. Free energy is hot water on a garden hose. Light in your house during the day from the sun, a cool breeze lowering your AC thermostat. Natural forces are free in comparison TO PAID UTILITIES or burning wood for cooking.
All things cost money to keep working so I guess nothing is truly FREE. LOL
But, when my Stirling Engine is running off of the sun, FREE:-)

Dan have you tried making a dish out of your solar reflective film and gauging the effectivness between that and a "proper" one. Stretch some film over the end of a barrel then suck the air out of the barrel. As the vacuum pulls the film tight it forms a pretty perfect parabolic dish. I haven't played with a proper mirror dish but would like to know the comparisons. Thanks for the video

@silverbird58 I am a ham of 31 years. The code literally translates as jibberish "BC TA0WBC 0" and I doubt would be considered as valid code groups. Code groups for radioteletype tests as the FCC gave, included 5 character groupings which could include letters, numbers (such as the zero heard twice), and up to around a dozen punctuation symbols, such as , . ?

greg357159, - easy, satelite dishes are focused on the existing LNB, (the arm with the "eye" on it that recieves the signal), is perfectly focused...personnally I would replace the LNB with a small boiler to power a small steam engine...this would work great with the old C-Band dishes.

luc59457 2 years ago
no.
If you are reflecting solar energy to the focus, you will have something at the focus to gather the energy (photovoltaic cell, steam coil, etc).
If you put your LNB in there, it would cook it.
(and it would block the light from hitting your heat coil)

Hi Greenpower , It is really great to exchange the ideas. I am quite entusiastic about finding the alternatives. And your videos are really nice.

there are tracking system available , just search for 'olar tracking equipment" in internet surely you will find some website , however this paraabloc dish can be used for heating water during day , if you make some arrangement to hang a wsmall copper cyclinder which is colored black, and make water circulating arrangement to that copper cylinder , you can use very chip water pump with very less wattage to circulate water and store into the your water heater tank, of course need control systems

I'm not sure why he hasn't directly responded to requests for information about the mirror film, other than simply trying to protect his market?
I'm not sure exactly what he's using, but I know a material called ReflecTech will do the same job and I think already has the adhesive on the back too.
The manufacturer's site sells it, but the smallest quantity is 150 sq ft. I also found a site which sells smaller quantities. It's expensive though.

I will have some on my website soon. A large 4' x 8' section costs about $150. It is thick like a business card and 95%+ perfect mirror. The back side needs adhesive. I use a 3M mounting spray. I had to make some adjustments and the video will be out soon. Material on our website in a few.

I polished a 7' aluminum dish, it wasnt nearly as reflective as the mylar. That thing was HOT. It would boil a coffee can of water rather quickly. I never got to the main idea- power a steam engine with it. Is there a way to figure how much power would be available with , say, my 7' dish?
A trackng system would be easy to build.
eimac4x1 2 years ago
You can get Aluminum to 90+ if you have the time and the right buffer and paste. I have seen trucks with doors that are amazing.
You have about 36 + sq ft roughly 3500 watts of heat energy at 100+ reflectiveness. If you have a 70% mirror, you are 2500 watts roughly. You would need yo take 25% of the figure for efficiency loss engine boiler generator converter. 2500 x .25=625 watts in a good scenario.
