Dan for President !!!!

[hemapriya114]

how to prepare this sun direct & what are the equipment used in this operation & where the components are available in madurai in india?

[Cationification]

You seemed a little nervous in this video? True or False?

[ASADLATIF1]

JUST THE THING I NEEDED....THANKS MAN

[medirobe]

Mr. Rojas!! Quick Q, have you ever attempted to start a fire with your avg dinner spoon? Considering it's concavity/parabolic properties, does it have enough surface area to reflect enough light to ignite a small amt of tinder? It'd be easy to walk around with a shiny, proven spoon to start your fires in emergency situations..

[sundogforlove]

could I use this to melt the snow off of my driveway

[thecrankypirate]

is this dish conversion better(efficient and advanced) than pv cells or solar thin films??

your other video used a stirling engine.can u tell me what was its capacity ?

can i use dish conversion for 3-5 Kw?

[thecrankypirate]

what are the part B and part A film called??

are they solar thin films??

[GREENPOWERSCIENCE]

@thecrankypirate reflective film on our website.

[crownvictory1]

i really like it how hard i search to know how to do that

i wanna know what kind of paper you used it wher can i found it?

finally you are a really good teacher i ever seen

thanks alot and hard luck

[spudgunner51]

what he is using is also called mylar which you can buy in sheets.

[Tomahawk7670]

it will burn my weed in secounds

[JrRoyals15]

is relfective film transparent?

[icicicles]

Part B film, I didn't back the vidieo up far enough.

Thanks anyways Dan!

[icicicles]

I'm sorry Dan, I couldn't quite capture what you called that reflective tape?

Thanks for all the great info in your videos!

[liquidice77]

you can use to boil water and get an steam generator :D

[gma683e066736]

Could this be used to make a telescope?

[Films4You]

@gma683e066736 This is something I would like to know as well... but the focal lenght looks far too short for Moons and Stars, etc... Also too uneven, this is a shame

[Wazabooz]

Thanks for this. Learning & applying knowledge so we can do more for ourselves!

One thing, your videos seem a little dark, even with my monitor turned all the way up. There are free video converters that can brighten the whole thing with one click. Or you can put more light on the bench.

[GameOver1260]

3 ft. triangular blades that focus as you open and close them.... use real mirrored glass and fire proof solar cells. Make "enough" energy, ok?

[Orangmaniac]

Wait, wouldn't whit paint be better? white reflects light and black absorbs light. If not, please explain.

[notreallydaedalus]

@Orangmaniac Yes, white would be better. Black makes it easier to see a reflection in it, so many people tend to think of that as a better mirror... but you don't want a mirror (which is for seeing images) in this case, you want a reflector!

[jozefchrenko]

beautiful cat

[jacc199]

Hello, I speak Spanish so I did not understand the instructions. I wonder what kind of tape or paper you used. Sorry you had to use a translator. Infinitely appreciate your response. Excellent video, greetings from El Salvador

[Lokivoid]

"to get to be a mirror it takes alot of work" No it dosent, after its sanded you do a chemical nickle plateing then a chemical silver plateing there its now a mirror, no buffing required. Besides trying to create a mirror with stright aluminium is pointless the crap passidises almost instantly.

[seindich]

@Lokivoid silver gets dark much faster . Simply apply polish or some another covering 

[nsobieck]

Dan I think you and Denis do a very good job teaching and demonstrating all your ideals and talents, thanks for sharing your knowledge...

[zaiuswasright]

Hey Dan! I really enjoyed this video! I scored a free dish from Direct TV and will begin the transformation process. I used Mylar as a quickie fix and got enough focused energy to boil water, but the focal point was not sharp enough to really get things going. Great Video!

[m92559]

I was wondering how well these would work if you polished the dish with jewelers rouge. We used to polish semi truck rims with it and they would blind you when you were done. We used a grinder with a polish pad and sticks of jewelers rouge. Its takes awhile but works wonders

[mattmaes]

Great vid. Would CHROME PAINT work as an alternative?

[Rideslow6977]

Ok....you harnessed the suns power...wow....now what? Is it one of those emotional touchy feely things? Guess I dont quite get it yet. We've been trying to use it cheaply for decades to no avail. This 18 inch disk is good for nothing more than receiving television channels. If you want to boil water, try a match and some dead wood.

[iamsoyelpato]

dear greenpowerscience - you're a great dude and doing an important job in teaching people how science can unlock the seemingly endless potential our natural world gives us -

also, i sent a letter to discovery channel encouraging them to take a look at your stuff - i sincerely hope they give you a show so that more people will think about the world like you do -

keep on keeping on :)

[321ozzy]

I finally got hold on some dishes and will follow your clear instructions to make my solar "water cooker" for a tasteful cup of coffee.

It is good and honest that you show close-up that even, besides all the precautions, there may be air spots and dust particles.

Regards from Mexico and keep up the good work; it's a joy to see your videos with and without your (enthusiastic) wife.

[GREENPOWERSCIENCE]

@321ozzy :-) Thank you for the nice comment and sharing. Enjoy your coffee.

Dan

[lamemaleable]

actually, America blessed G-D, fool.

[sentiments]

hey, how much does the reflective tape cost?

[three0234]

im looking for an enclosed thermocouple. i looked on globalspec the engineering search engine. nothing there so please help.

[three0234]

hey what if used one thats more oval shaped? would i use the three original focal points of the tv signal? or am i fine with one enclosed thermocouple?

[wellmeka]

What exactly is the mirror sheet you used and where could i get my hands on some?

[bogubbi111]

cool guy. i built the same. thanks man. very good teaching!! 5 stars. respect

[alvesbeirao]

Jackass,you don't need to cut that thing at all!

you only just need to wet the dish with soap and water!!ahhahahhahahha

[living4game]

Man! You are really a Teacher. I wish that  God Bless You! Really Thanks

[GREENPOWERSCIENCE]

@living4game ;-) THANK YOU!!!!!!!

[laxwork]

@living4game there is no Got! look the world... and think...

[living4game]

@laxwork first of all if I understand correctly, the god I believe is here life sicience everything because of him and his existence. if u ever little bit interested in science, you may see how perfectly designed life. and u may see engineering is high above which homan could understand! and if you look at your human body, which is Called Utimate machine and repair itself and could produce it self. the perfect machine should a designer an producer!

[laxwork]

@living4game I look at the babies that die before learn about any god, I look at the wars, I look at the rich and poor people. Most of all I look at the poor countries that kids just die...

I like reflector, I just believe that god only rich/healthy people can bless...

:-]

I know many people believe in god, maybe the most. But they believe only by them ways... They r ready to kill/hit the most of them!

have a wonderful night

[Oskaritube]

Nice tut! BCÜTA0WBC0 = morse code at the end :)

[katholamew]

i agree. what more can i do with this than boil a bottle of water and burn sticks? i have a solar water heater in mind as an outdoor bathroom application. and maybe burn a hole in a steak. i would like to know what more can be done with this than possibly burning down my outhouse

[jaffa25]

get a smaller solar panel and capture the sun from a greater area.

works out a lot cheaper to use a large mirror and small cell than just using a large cell...

a heatsink might be needed depending on the area/season but thats pretty straight forward

[tsport100]

@jaffa25 A heat sink behind the PV cell is essential. Most silicon cells have a max operating temp of only 60C. At the focal point of even a small 1m dish you'll get 600 - 800C. If the cells are 10% efficient that means the heat sink must remove the remaining 90% of the heat.

This can be drawn off for water heating, steam generation and/or some kind of power generation using either stirling or rankine cycle.

[jaffa25]

if you fork out a little more on the solar panel, sharp (i think) has a triple layer cell that is around 40% efficient (there are probably more but this one i've seen around )

im not saying it would eliminate the heat sink but would mean 1/3rd less heat energy. :)

[PleasureTV]

Really useful mirror guys

even Your project fails, you can use it for shaving yr Balls

[AxenZoku]

You could make a bunch and put them in a circle and focus all the focal points to a single point, say pointing at a metal boiling pot or some steam engine or something :)

[davo16747]

i dont go green i go toxic green

[rayofminneapolis]

BRILLIANT! You made 30 of them!?!?

[InvisibleRefugee]

Ok.. all of the videos I see posted on this subject don't say what we are to do with that concentrated heat. Why go thru all that trouble just to light sticks? How do you apply this to heating water or your home or making electricity? FYI I don't own a home, but if I had one I could figure it out myself... I'm trying to come up with ways to apply this stuff to heating an apartment I rent.

[dhymers]

Dan you ROCK.

I just pulled one of these from a neighbors dumpster after helping my father in law build a dish from scratch (3 footer from cardboard and chrome vinyl) now I can make my own for freeeee. nice.

[kmsdadog]

ok, im new at all this, can this be used to reflect the sun rays onto a soler panel?.. I hear the Israeli's have this to power large wattage inverters for hospitals and government buildings...so, will it help or not?...thanks.

[dhymers]

kmsdadog - Those are probably not reflecting onto PV panels, this may increase their output, but it will greatly decrease their lifespan.

They are probably collectors focusing on heating some liquid to generate electricity in a turbine or other manner.

[BrennerMaschinenbau]

lhave a look at

london-delhi1

[Ghaztoir]

Will this also reflect concentrated sound waves? FYI, I'm curious at all of its applications, and I'm also trying to line my walls with sound-proof material. Neighbor issue, ftl!

[GREENPOWERSCIENCE]

Yes, it will. Just place the mic at the focal point.

Also with your Neighbors, are you keeping their sound out, our your sound in?

[Ghaztoir]

I'm trying to keep the sound in, since I have a movie theatre stereo system that is hooked up now, but can still be heard from outside. The room its in is like a guest room, not too furnished or anything.

[limeytrash]

You're completely on the wrong track for sound insulation. A solar dish isn't the answer haha. You need soundproof egg crate type soundex foam to absorb your noise. Carpet will absorb some sound but not near as much as materials made for this purpose.

[GREENPOWERSCIENCE]

re;

post from Sept.

You need fireproof foam for the walls or cushion behind the drywall. Even a thin layer will work. The sound vibrations transfer through hard surfaces. Try prosoundfoam com

[Ghaztoir]

Looking into it. Thx for all the help!

[limeytrash]

But you won't need to add reflective coating to bounce sound waves. The reflective coating is only needed for solar applications. The bare dish will work perfectly.

[Blondets1]

Just think of doing that to one of the big 10 foot parabolic dishes!

[GREENPOWERSCIENCE]

watch?v=ElXHAFq13jI

[SunshineCooking]

We did a project similar to this. We used an 18" dish. It can burn paper, but it doesn't get hot enough for us to at least boil water. Perhaps we need a bigger dish.

[limeytrash]

18" dish won't boil water? It should but will take awhile to reach boiling. What type of reflective coating were you using, aluminum foil?

[XabiDellugo]

would it burn the camera sensor? I mean if it's a digital video camera, I think.

[Rideslow6977]

Its cool , but WTF do you use it for?

[ablestmage]

starting a campfire, boiling water..

[LoneJackel]

@Rideslow6977 torturing small green mountain-men

[Xamizer]

Are you familiar with vacuum forming? If not, wikipedia it. Back? Alright. What if you perforated the mold with holes, hooked it up to a vacuum from behind, put an adhesive on the surface, and vacuumed the material into it?

Great videos.

Thanks,

Max

[trek1200233]

I found the parabolic mirror I bought at a flear market for $10 many years ago . Am able to produce over 1000F and melt a pie pan.

[paintballdude902]

well....when you take the dish down there are 4 bolts that fit fluch in the holes....i know im a tech

if you really wanna make it look pretty withou the mylar start with 100grit then do 200 jump to 600 the 800 last finish with a very high grit (2000ish) it can be found at an autozone type store for removing scratches from clear coats

[cryptostorm]

not really... 800 grit sand paper and a good aluminum polish will give you a really good mirror..

thats how I restore my polished aluminum rims after a salty winter ;)

[Criptografo]

great i have been thinking a similar idea for these dishes so great u can add a stirling engine in the focus! greetings from mexico

[spinnerZulu]

This is what they should have in the most poor parts of Africa and India. Insted of walking milies for wood to do their cooking, thay should have mnirrors like this.

[mephil8800]

or use solar ovens.

[jnos45]

i like the parabolic video but can they be used to reflect the sun onto my solar panels safely during needed times of the day?

[BloodTar]

Fill the bolt holes in with bondo and sand them smooth.

[timerider4]

My neighbor has one of those old giant dishes, like 5-6 feet wide. But it is made of a screen type material, so you couldn't stick anything to it.

[bg0821]

I've done this with a 20x22 inch dish. I collect the dishes now and lined several lol. I wish someone would throw out a 3 and half foot dish that would make even more power. Ive cooked a single burger in a tiny 4 inch square cast iron pan and it works well, but cant do much with a 4 inch pan. anyway, instead of having to put the bolts back in like you did, you can fill in the holes with jb weld and then sand. the bolts stick up higher a bit but either way, doesnt matter too much. nice video.

[warlion]

i belive is easy if you put water with soap first you put the reflective film, this help you to remove bubbles and help you fix if you make any mistake

[hanicken]

thanks, God bless you!

[goingreen89]

Hi Dan. How far away was the focal point? Im guessing that it would boil water also. Thanks for the video.

[melibre64]

good video,

[flyboy3633]

A small comment when applying the reflective tape. Twist a towel into a snake shape and lay it on the bench in a circular shape (like a donut). Place the dish in the middle and the towel will support the dish and you won't have the dish rocking around while you're applying the tape.

[energiaregia]

Good Video, very clever to take a dish into something useful, now to build a device for heating of water and a guide to the sun .....

[linuxbox25]

: ) so how can we use things like this to power our computers or microwave? : ) i'd personally just like to see actual examples of real life situations where this can actually serve some normal purpose in life that we all rely on on a daily basis. i mean, create some electricity with this or something or show some good use out of it!

[Frosttty]

LMAO! I dig the ominous music when you're burning the wood.

[jsec88]

Hey Dan,

good video, but I wanted to point out that the paint these dishes have is not totally non-stick, I've lined one of these dishes before (posted an article about it at the builditsolar website, solar cooking section) and the autoadhesive mirror film did stick to it. It will come off fairly easily if you pull it, but it wont fall off on its own, so it probably isn't necessary to sand it although sanding it will definitely make the surface smoother because the paint is actually a bit rough

[kaduisaui]

excellent video.

[RawVisualsVj]

You could use some varnish to seal the edges to help prevent moisture getting in perhaps

[JavaLessons]

This an option ? Heating a single sheet, while sucking out the air fom under it ?

I saw something done like this, but not on a dish. Gonna look that one up.

[teemuruskeepaa]

Wow, this is an excellent how-to-do video. I'm after a parabolic mirror for many reasons, for example to boost my 3G modem, and it would certainly be a great tool for making fire. But I can't think of any place in this hick land to find dishes. Concerning the foil, maybe hardware stores sell them?

[WhoRonPaul]

we found that using a small vinyl squeegee works well too for pressing the air bubbles out. we used a 4" squeegee on our project

[qstendious]

If you don't mind, where did you get the sticky reflective film?

[VisionQuest2012]

It's called Mylar and you can buy it by the roll.

[WhoRonPaul]

The Solar Reflective Film is posted under description in the video. It's available at their website

[qstendious]

Thanks for the reply. I know you can buy it at their website and I realize that he tells you that in the video. The reason I asked you is because I noticed you live in the phoenix metro area and thought you might have bought it locally but I guess you got it from his website. I wanted to pick some up instead of having to mail-order it.

[synaptic76]

Check any hobby shop. I know that there's one on 19th Ave. and Northern. Ask for adhesive-backed mylar in the model airplane department. They also sell a little iron that looks like a shoehorn with a rheostat for temperature control to facilitate melting the adhesive backing. The Iron and several meters of mylar shouldn't run more than about $30.

[godsend420]

nice vid i have these all around me the dishes i mean so when tshtf all ur dish are belong to us 5*

[IdahoViewing]

I think I would use a piece of terry cloth to smooth the material down.

The short cut off pieces can be placed near the edges of the dish where longer pieces are not needed.

[Probewitch]

Is there anyway to use the dish as a mold; acrylic clear coat the silver film, then peel it off as a super lightweight reflector?

[GREENPOWERSCIENCE]

The dishes unsanded are like teflon and a light wax spray will release just about anything. I think if you punched some small holes in the adhesive, this would allow the clear resin to lock it in when finishing side 2. There would be no release barrier that the sheet would otherwise create.

Good idea, not sure what resin would be best.

Spray would be too thin.

[livehazelgreentraffi]

LOL!!!!I

I WAS LOOKING AROUND FOR A CAT WHEN I HEARD THE MEOWING!!!

Thought I was going crazy... I dont own a cat. lol

[GREENPOWERSCIENCE]

:-) He is a stray that adopted us. Great cat and does some really crazy things. They other day he was meowing but taking. I thought I was watching a digitally doctored youtube video. Got the camera and he stopped. Would have been worth a million views on youtube LOL He splits to the roof when our dogs are out of our house in the big yard.
