My Solar Revelation!
 
I discovered as of recent that using dark color to absorb energy from the sun works very well.. so well I can heat one room to 75 degrees when the sun was just right in the last place I lived, with no other heat sources..

I have made (unedited as of now)videos proving this but the proof is in the pudding,

I just snagged a place with new windows, insulation, and I applied the techniques at my new place

basically the materials consist of dark blue(tinted with blue and black and maybe some purple, not red colors(you can see this when you shine light through a sheet)) bed sheets and black that allow light to pass through basically you use these as curtains on your windows, and when then sun is out on that window pull up the blinds and let the sun hit it, PULL BACK THE END OPPOSITE OF WHERE THE SUN IS HITTING THE SHEET TO ALLOW THE NATURAL CONVECTION OF AIR TO PULL THE HEAT OUT OF THE BLANKET OR SHEET LIKE A RADIATOR,

IN A MATTER OF MINUTES YOU CAN RAISE THE TEMPURATURE OF A WELL INSULATED HOUSE A FEW DEGREES. THIS IS WAY MORE PRACTICAL THAN 30,000$ SOLAR INSTALATIONS, THESE SHEETS ALSO ACT AS CURTAINS OR INSULATION AT NIGHT TO KEEP THE HEAT IN, THIS FORM OF HEAT IS MUCH HEALTHIER AND MORE NATURAL THAN GAS, ITS LESS DRY

I CAN GET THIS PLACE IM IN TO 76 DEGREES USING THIS METHOD, I AM USING A DIGITAL SURFACE THERMOMETER TO DO READINGS.

OTHER PROJECTS USING COLOR INCLUDING SOLAR PANELS MADE OUT OF BLACK PAINTED ALUMINUM OR PLASTIC PIPING SEALED IN A BOX USING A FAN TO BLOW THE HEAT INTO YOUR HOUSE, UNFORTUNATELY ALOT OF THIS STUFF NEEDS PERMITS, PUTTING CURTAINS ON YOUR WINDOWS DOES NOT, AND COSTS A ALOT LESS, I PAYED ABOUT 50$ FOR ALL THE MATERIALS NEEDED FOR THIS FOR 12 WINDOWS.

also 100% flat black paint will add to this, but be careful of semi-gloss paint, it'll add a cooling effect to your house, flat paint is warmer feeling and absorbs more heat energy you can paint ect if you find true flat ultra black paint, but paint manufactures don't have this available, I found a gallon of 15 year old black paint on the curb being given away with other paint AND THE PIGMENTS IN THAT PAINT ARE MUCH DIFFERENT AND RICHER THAN NEW PAINT, DUE TO EPA REGULATIONS AND CHANGES IN PAINT MIXTURES PAINT HAS BEEN MADE TO NOT ABSORB AS MUCH HEAT YOU NEED TO FIND AN EXACT PAINT FOR YOUR APPLICATION IS WHAT I AM SAYING, AND MOST OF THE PAINT OUT THERE IS NOT IT.

For example:
Home depot does not sell any flat paint at all, end of story.
they call it matte/flat, which if you go to a real paint store they will TELL YOU SPECIFICALLY THAT MATTE IS NOT FLAT PAINT REGARDLESS OF WHAT THE GUY AT HOME DEPOT SAYS. I NEED TO RESEARCH THIS MORE, BUT I HEAVE HEARD THAT BLACK EXHAUST PAINT MIGHT WORK..

find a room in your house that is cold all the time, try this and then you will understand what im saying also tucking in curtains so theyre snug against the windows helps, air moving against cold glass, also this is the same idea with semi gloss paint, its a colder surface so it can cool your house down more

this will work differently in different climates when its colder outside and the glass on your window is cold so you have to be aware of when to pull up blinds to all the sun to hit the sheets and close the blinds when its done. there is some manual labor but not much and the payoffs are big

Thanks for the tip!
Avoid black primer, it fades in the sun. I've used 'flat' black barbecue paint and it doesn't fade at all.

spotaneagle 03-10-2010 04:37 AM

do you mean you used grill paint as a solar heat absorber?

if you get any black paints make sure you compare them and find which on is darkest and has no sheen at all, sheen=reflect light/energy

ive put countless hours into this project so the gratitude is very welcome. I have also been doing this before the whole obama is gonna paint the rooftops white thing hit the news, I was thrown at this idea by the fact that I spray painted the hood of my old car black and saw the tempurature of the engine go up higher than usual in 2008, but I have been waiting to prove it to myself before I tried to teach anyone else about it, but now I have video documentation. and like i said 75 degrees in one room= my entire apartment was heated during the day with no help from gas and would stay warm into the evening maybe 3+ hours after the sun is down.

current heating house via: dark blue fabric

also been reading about other likewise application and they say that you only need a 2mm gap for natural air convection to occur on ecorenovator which is pretty much in agreement with what ive been saying in this post

Folks in the roofing business know this really well. On a hot day, a roofer would rather be standing on a white TPO roof than a black EPDM roof. They recommend white shingles to homeowners with high cooling costs.

Many years ago, a co-worker put a frozen pizza in foil on the roof mid-morning. By lunch it was thoroughly overcooked. That was the same roof we were working on.

Jay2TheRescue 03-10-2010 06:08 AM

That's why there's a lot of light colored roofs in Florida.

spotaneagle 03-10-2010 07:51 AM

we need houses that can change color in the seasons

theholycow 03-10-2010 07:54 AM

How about a green roof?

GasSavers_BIBI 03-10-2010 08:09 AM

Ford's or GM's (cant remember) production building in Detroit have green roofs. On the long therme, its simply more efficient cause you dont have to change the roof cover every 15-20 year). Also, its offer a great protection in summer for the extreme heat. Also a major point is that big building aint a dead zone anymore, life can grow.

spotaneagle 03-10-2010 08:16 AM

or get black sheets, or carpet, theres alot of black carpet available, its kinda strange, but you could use that cheap black carpet stuff as a solar collector/radiator if you drilled some holes in it and hung it over a window

GasSavers_BIBI 03-10-2010 12:02 PM

All you need is to open your sunblind during the day on sunny days. Free and cheap.

And ho! close them if you wanna keep cold air during hot days.

spotaneagle 03-11-2010 03:09 AM

yes but the black pigment/blue sheet ect adds extra wartmth by far vs the sun hitting white plastic of semi-gloss white paint get a surface tempurature scanner

go sit in a white car then go sit in a black car and tell me which one is warmer

bobc455 03-13-2010 03:45 AM

We used grill/BBQ paint at work on some metal objects that we wanted to absorb heat. It would actually make some of our processes up to 3% more thermally efficient compared to bare aluminum.

(3% might not sound like much, but when you spend $1.5 million on a machine and you can increase productivity by 3% by purchasing a can of spray paint, that's a no brainer...)

aluminum flashing gets extremely hot in the sun alone, I know from experience, it had a sorts of non reflective surface that is grey, with a dark element to it in a sense

grey on a computer is partly made of of black, same with paint, so you can see where im going with this..

Jay2TheRescue 03-13-2010 05:39 AM

Yea, aluminum gets hot, but he's saying it gets hotter with the addition of some black spray paint.

spotaneagle 03-14-2010 05:18 AM

Exactly but I'm inferring that aluminum is a great heat conductor to begin with thats why the aluminum can(painted black) panels work well

Then u have this too:

I like the top one way better for home use, you can hook it up right out side a window.

What I'm doing is basically the same principle

Heres the video about it:
https://www.youtube.com/watch?v=bRZvA...layer_embedded

I have a friend that built one of these.

spotaneagle 03-14-2010 05:35 AM

I had my window sills painted black and some other stuff at my last uninsulated place. I left it like that too the landlord is a lazy ***. He hasn't done any work to the house since he moved in 30 yrs ago so I was forced to do many improvements. no insulation, 100 year old windows drives you to these things.

Thats how I was getting to 75 degrees on sunny days in the middle of winter, black carpet, black sills, dark cloth, that houses' heating system wasn't capable of heating the house to that temp.

I was also using seal and peal.

During the month of January you get the best sun for this too, because the rays of the sun come further into your house than in Feb. So during the height of winter I was getting my best results, pretty paradoxical, huh?

That house is a tragedy and I should've never moved there in the first place cheap rent is appealing though.

Yeah , It's the FORD plant. I saw a documentary about it a while back.
Stores water as well as adding thermal insulation and helping the air conditioning costs and heating costs as another benefit.

Good to see industry getting aware and acting on this.

Fly into any major city and the area of roofing over factories and warehouses is vast.

I always loved those buildings with vines all over them, I hate when they cut them down... such a shame..

Jay2TheRescue 03-18-2010 08:56 AM

Usually when you have vines & ivy growing on a building its a bad thing. The vines usually break up the mortar between the bricks and actually let water in there to further break up the mortar, causing the wall to deteriorate. Yes its pretty to look at, but it can do some serious damage to the building if left unchecked.

Great opportunity for some go-getter to fill up that space with solar panels...or to plant a large garden...
