** This is a flat 6 Segment of producing an effective work are of 8 “. No measurement on temperature yet due to bad weather. Parabolic reflector solar This is a 90% + mirror. Acrylic solar The mirror must be mounted and has a 12 “diameter hole in the center. 3318 “square (21,406 cm) – 113″. Square (729 cm) to the center = 3205 “sq inches (20677 cm) 8″ working area with a diameter of 50 “66:1 ratio 1.9 square meters These figures should be doubled checked. Video Rating: 4 / 5

** The Vanguard Solar Parabolic Dish Stirling system set eight world records technicians for the conversion of sunlight into electricity network in 1984. Foremost is the conversion efficiency of 29.4% which remained unsurpassed until Sandia National Laboratories has exceeded November 1984. ADVANCO Corp was the prime contractor to the U.S. Department of Energy and the small company was owned and directed by Byron Washom Video Rating: 5 / 5

  2. could you say what is the main difference if you use metal sheet or acrilic sheet? one of the disadvantage for metal sheet is only wieght and one of the disadvantage for acrilic sheet is cost ? which one do you use, you get more spot light? and also how is making parabolich dish for assembling parts? is it only flat sheet or ready parabolic sheet? please answer me as soon as possible because i am making an experience and so it is important for me there is no time for me.thanks

  3. Around the end it looks like space for a second.

  4. Good advice to all parabolic mirror builder. Please protect your eyes and your skin.  The UV radiation is also multiplied!!!

    By BildhauerEder on Oct 30, 2012

  5. Could you mount a reflective cone and/or prism at the focal point and channel the light to a smaller diameter, maybe something the size of a pinpoint?

  6. I have scrapped this idea, they are way too fragile and the beam is too scattered. I was hopeful it worked. This dish is now in many pieces:-( Darn wind.

  7. Where can i get one of these ?

    By Zoomtronic1 on Oct 30, 2012

  8. I have produced steam with an old 8′ dish covered with sign quality reflective film. I will be posting more, but currently I have the dish facing down testing the longevity of the film. It has been out for about 6 months now in the Florida sun and the adhesive is showing no signs of degradation.

  9. The acrylic for this design was too thin and produced a poor spot. Also because of the moulding process, there was little control over light scattering. We have up to 46″ mirrors on our website greenpowerscience they are true shapes with great spots, just smaller. The acrylic is also thicker so they don’t break easily. This mirror array is now in pieces:-(

  10. Why is there nothing on here as to how to get one of these?

  11. Did you bought this parabolic or did you made it yourself?

    By LetsCook2gether on Oct 30, 2012

  12. say whatever you want but this is a cool mirror , meaning you can heat water infront of it and heat your house for free man … you know . Make a lil water container and five of these guys on your roof and in winter time boil water and live like a king man .

    By Anomiman on Oct 30, 2012

  13. I think this would be used for a Solar thermal type system and not directed towards solar PV panels.

    By Jimbo282 on Oct 30, 2012

  14. if you focus the mirror on a sterling engine (its like a steam engine) it can produce power for free.

    By rageunderground on Oct 30, 2012

  15. What’s this mirror’s purpose? Won’t it just burn up solar panels?

    By piwacket33 on Oct 30, 2012

  16. That thing is amazing! How long did it take to burn the stick?

    By Shaunt1 on Oct 30, 2012

  17. Why be so condescending? People come to forums like this and ask questions to learn – sometimes with no previous experience with these products, materials, results and possible uses.

  18. … You’re kidding, right?

    By Paradox3121 on Oct 30, 2012

  19. I was wondering if you would have a steel or aluminium dish, you could electroplate chromium onto it. You would need to plate copper, then nickel and finally chromium onto the dish. But I think it would be hard to do do it uniformly, and you would also need a lot of Cu/Ni/Cr solutions, and nickel would be particularly hard to come by.

  20. 2 square meters is the right size to make heat. I made experiment with 1 square meter and I think it is not enough in canada in winter (-30C in January).
    Thin mirrors (from bathroom) cut in small pieces is very good and cheap.
    The thickness of mirrors is important. It has to be thin (less loss in absorption of solar energy) more reflexion.
    Do not use aluminium paper not a reflexive material.
    Take care – chris

  21. I think that would be a great idea, this is distorted because it is just propped up. The problem with thicker acrylic is cost, there is over $600 in raw acrylic in these before work. Thicker acrylic will not works as the pieces will not fit and also too expensive.

    The imperfections are from the moulding process, they are like little bumps. The mould is very rare and acrylic usually does not show the imperfections when clear but the metalizing brings it out.

  22. :-) Happy Holidays to you, Thank you.

  23. I have tried all major brands from $8.99 krylon to $129 kkans CRAP!!!!!!

    Cheap $3 silver is better than them all, still not solar worthy . this is metalized.

    By GREENPOWERSCIENCE on Oct 30, 2012

  24. I have tried all major brands fro $8.99 krylon to $129 kkans CRAP!!!!!!

    Cheap $3 silver is better than them all. this is metalized

    By GREENPOWERSCIENCE on Oct 30, 2012

  25. I do not want to bask company names but there are 2 that sell spray $129 can, black gloss silver wipe and clear. AVOID, JUST SILVER PAINT, if you look at an angle it looks mirrored but so does gloss black, CAMERA trick, customer service “please hold” NEVER returns. Called 10 times. Either they are really busy or…

    The metalizing process is the only real option.

    By GREENPOWERSCIENCE on Oct 31, 2012

  26. Yes, this is metalized, the spray stuff, even the distilled water wipe is not a good mirror.

    By GREENPOWERSCIENCE on Oct 31, 2012

  27. what?

    By Lars Evers on Oct 31, 2012

  28. yea now its ses and a complete vampire of the public wealth the best thing you could do is release any files you have reguarding the dydrogen steriling enginge and generator setup… that all americans have overpaid for…

    By Gade Green on Oct 31, 2012

  29. 28 years on and we still use fossil-fuel… The powers that be want it that way and it will stay that way until we all come together as mankind and say a big NO to the military-industrial complex that’s running/ ruining the world. Until then…. let’s work over-time just to pay our bills and carry on with this lousy life…

    By peacekeepermoe on Oct 31, 2012

  30. cheap cheap and cheaper low cost per btu all this high tech stuff is a big load of poop . 

    By bryncomeaux on Oct 31, 2012

  31. it cost so much it only proves solar is too expensive . its over designed over priced. a good redneck can make solar cost affordable but your aesthetic just wont let that happen. if you want a real solution you would hire an interior designer to make a backyard redneck low-cost per btu version look more professional because that about all this has going for it. its other improvements just make it too expensive to ever use.

    By bryncomeaux on Oct 31, 2012

  32. nice try… but your reply, fails the test… not worth dissecting all points, one need only read your wording in the post I replied to, and my answer you now reply to… it says it all, and still stands as you again insist the idea was taken forward…(a slight adjustment of your earlier comment ‘dwarf this thing’). Moot point.

    By DormantIdeasNIQ on Oct 31, 2012

  33. You might want to read what I was replying too before commenting… ESPECIALLY if you plan to label the person as an idiot. They were claiming that this technology was never used. I was just pointing out that someone took this idea and moved forward with it. Not only did they move forward with this idea but they have done it in a BIG way. The wild thing is that you seem to be agreeing with me. There is nothing like someone calling themselves an idiot without even realizing it… lol.

  34. Dan:When you have 1500 lbs canterlevered at the focal point, two 3/4 hp drive motors tracking to .1 milliradian and a radiator for the Stirling engine, and an emergency slew system, the parasiitic power all added up to 8% of the gross power produced. One would offsset by the addittional harvest of the daily DNI in two axis rather than single axis or non-tracking (no cosine losses). The net energy efficiency of 29.4% of DNI to electricity to the grid remained unsurpassed for 24 yr. – Byron Washom

    By Eastof2morrow on Oct 31, 2012

  35. btw solar panels are just so much better than a mechanical system

    By Dan Frederiksen on Oct 31, 2012

  36. 8% of the energy used for tracking the sun??? that sounds as wrong as can be

    By Dan Frederiksen on Oct 31, 2012

  37. I hate idiots who say nothing and sound like ‘mine is bigga’. This device in an array would accomplish the same. The principle is there. …and arrays are space consuming and all fall when the cloud comes by. Separate units spread out strategically, safer, less hogging of the land as they can be installed on existing structures, less of a need for high-power lines(if any at all) to spread the energy! Also tactically safer in case of war damage, and so on and on and on. You still feel big?!

    By DormantIdeasNIQ on Oct 31, 2012

  38. Magnifying glass and a leaf? A LEAF!? The real science nerds did this with ants and other bugs, we were… INSECT GODS!

    By doceigen on Oct 31, 2012

  39. There are actually solar farms that use this concept. However, they dwarf this thing. There are rows and rows of panels focusing light on a single tower. To give you an idea of the scale, the tower is several stories tall.

    By 101perspective on Oct 31, 2012

  40. Absolutely outstanding! Thanks a lot for this contribution. I’ve only seen old pictures of this dish and I though that this experience was definetively lost and dispersed.. nice for those like me who never stopped believing in solar energy! sungiga

    By sungiga on Oct 31, 2012

  41. AH… silly us thinking that a product like this would be fast tracked into use. With the power companies in control solar and wind power are not as sexy as nuclear and coal.

    By 1foxtrot70 on Oct 31, 2012

  42. and after 30 years …… we still see these things only on youtube
