The other commenters are right, this design is actually worse than just letting the sunlight heat the room. What happens with empty window is some heat is absorbed and some is reflected onto other surfaces in the room, where it is eventually almost 100% absorbed. A window into a large room is essentially a black body absorber. The only heat that is lost is what is re-radiated back out the window, which is a small percentage indeed from objects far from the window.
April 25th, 2009 at 4:35 am
actually you are very wrong. The open window is extremely inefficient at transfering energy (you are wrongly assuming no energy is lost). The simple design allowed 100% energy transfer with no loss of energy. The REAL results were $1000 less fuel needed to be purchased for the winter compared to prior years (or 1 months free heat for the winter)

Please don’t knock this idea as something foolish. What he is demonstrating here is a Trombe Wall on the very cheap. Nothing wrong with that. You could improve the heat output by collecting outside the room and such. Or you could store the energy using the traditional Trombe design by replacing the black plastic with lets say tiles painted black left over from a 70′s bathroom remodel job placed in a frame in front of the window. Liked it, please keep moving forward.

Nice simple and fast. THis is excellant for the begginer solar experimenter.
Can you tell us what the air temp of the air going in at floor level, the room temperature and the air temp coming off the solar device at the ceiling.
I will certainly investigate this one but I will need to add the box heater to get my megga heating bill down for this coming Winter. That, Is my Goal……

typically incoming air was 65 degrees, and exiting heated air was 140 degrees during peak. The setup worked best when there was snow on the ground due to the reflected sun off the snow.
July 6th, 2009 at 7:03 pm
Like your inventiveness, but do wonder about neg effects of heating plastic. Would a black fabric work as well? Thanx.
July 6th, 2009 at 7:17 pm
it’s not any worse than your cars dashboard getting heated by the sun.
July 6th, 2009 at 7:49 pm
With all due respect, how do you know that? As skeptical as I am about BIG BIZ, I am sure testing is done to determine if a car’s dash will emit toxic fumes. Thin black plastic dropcloth, OTOH, was not designed for this purpose. Any thoughts on using cloth? Thanx agin.
July 6th, 2009 at 9:06 pm
if trash bags emitted toxic fumes from sunlight exposure, they would be banned than the lawyers would be all over TV saying.. have you ever used a trash bag? if so you too could collect money from X.
Cloth does not collect the heat very well, and I have yet to get it to radiate any to a degree to make it worth the trouble.
Aluminum painted black works very well
August 31st, 2009 at 3:39 pm
weaponeer there will always be Nay-Sayers …I’m with DUCK always “keep moving foward” Me disabled with tools and way too much time, will be trying this & others in winter…southern Arizona
August 31st, 2009 at 4:40 pm
I’ll be moving towards the aluminum can design next for my added heating. I’m moving out west as I’ll be losing my south facing window, but The system I used for the last several years worked VERY well for the cost (free), and I’ll be moving on to other passive solar designs to cut my heating costs in the future
August 31st, 2009 at 4:43 pm
I’m moving shortly to northern NV, and I’ll still be using this setup, as well as others that take longer to make and cost more but hopefully will be more efficient so I can totally cut day time heating and just use passive solar during the day
November 12th, 2009 at 12:14 am
Can’t be. Cause and Effect. At any point you will get X energy through that window, and once it’s in, you can’t do anything to amplify it. (You’ve admitted it works better when there’s snow… that’s because MORE light from outside is getting reflected in through your window) You are simply collecting and redirecting that energy. You aren’t accounting for the “lost” energy absorption of all the other objects within sun-shot of that window.
November 12th, 2009 at 12:21 am
If you are realizing an energy savings then there’s something you aren’t telling or you aren’t aware of. Do you live JUST in this room? If so, then you aren’t concerned about heating any other rooms and concentrating all the heat energy into this 1 room makes sense. One of the reasons a Trombe Wall works is because it adds surface area for the energy collection. Changing your materials inside your window does not increase your potential energy.
November 12th, 2009 at 2:19 am
You have two cars.. one black and one white.. both are in the sun and are collecting the same amount of heat.. the white car refects most of the heat rather than absorbers it, the black car absorbers it rather than reflects it. while I have done the testing, maybe you should try it sometime… take an assortment of colors, and measure the temperature. Under your thought process they all are the same temp, yet they are not. light colored carpet, dissipating much of the energy as light
November 12th, 2009 at 2:21 am
on to white walls once again dissipating more energy, yet transfering very little of the energy into heat.
November 12th, 2009 at 2:27 am
The design of this pulled in cool air from the bottom, and the heated the air, and automatically circulating the air in the room, which is a living room, dining room, with a kitchen (no wall), so yes… these rooms were the rooms that were occupied 90% of the time. prior years required one additional tank of Propane for winter heating. the efficient collection of conversion of that light energy into heat is why I spent less money on fuel. The snow acted much like a mirror increasing the light
November 12th, 2009 at 2:31 am
in the same manner that is used for solar cooking.
BTW the ceiling is a white drop down insulated ceiling that always stayed cool to the touch. by allowing all the energy to be collected on the wall I was utilizing all the energy and not worrying about dissipation, or trying to heat an insulated surface
November 12th, 2009 at 2:45 am
I don’t think that you understand your own explanation. You aren’t using a closed system for your argument. Yes, of course different colours absorb and reflect energy differently… but they can’t CHANGE how much energy is in the system. Your curtain is hotter by 20 degrees because everything else in your room is cooler by 1 degree.
Too many variables that you aren’t measuring. Temp of every room. Outside tempurature. BTUs contributed from other sources. How many times you’ve opened a door.

I don’t think you are following along. You do realize this is not a scientific paper or Theseus? It was a quick example on how I have been saving over a grand in heating bills. it’s simple passive using a very large south facing window. no I’m not going to waste my time telling you how big the window is, it’s azimuth, inclination. pointing out unheated rooms is a waste of time and not relevant. at the time this was the ONLY heated section of the whole house, but I’m also not going to work
November 12th, 2009 at 9:36 am
out the square footage of the area being heated by the passive solar. If you want that information, then test it yourself. I was only interested in the $1,000 less heating bill for the winter for the second year in a row. Outdoor avg daytime temp was approx 9 degrees F. the floor temp at the window was approx 60 degrees, with the top of the unit being approx 100 degrees with the center temp running approx 190 degrees.
November 12th, 2009 at 9:45 am
I can adjust the system so the plastic temp in the center runs around 250 degrees. as I had already stated the system draws cold air from the bottom, and it’s heated and blown from the top, circulating the air in the room without a fan.
THIS IS NOT A SIMPLE PIECE OF BLACK PLASTIC HANGING IN FRONT OF THE WINDOW!
This has a very specific design using fluid dynamics. It is a very simple design using thick black plastic, foam, and tape, in a unique bellowed type of design
November 12th, 2009 at 9:56 am
This is also not a DIY video, so I’m not going to show you the actual design, or how to make it. it just shows what is possible to make very quickly, and very cheaply if you take the time, and have a large south facing window suitable for passive solar collecting.
No one passive design approach is most advantageous in all climates or on all sites and situations
The type of passive solar being used here is a Direct gain design, and without window glazing.

i love it.
January 19th, 2010 at 3:06 am
Love this stuff, Glad I have a south facing windows..
