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.
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
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.
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.
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.
