  2. @RandomConcepts he didn’t really give info on how much heat it pushes. But my “inside” version can raise the temp by about 5 degrees inside the house over a period of a few hours.

  3. Husband and I built something similar as part of a solar dehydrator. Instead of hang it out the window, it just sits in a south window inside the house. It is currently 59*F outside and my passive solar heater is putting out 100.1*F inside the house at 2pm. I used an old 30gal aquarium for the glass, door jam, paneling, foam backed duct insulation, and aluminum flashing painted black. Works great!

  4. I’m not putting the window box in this year, unless my roommate is game for it in his window. sorry! i might try to get a friend to try it.

  5. are you still using this box, or do you roll it out for the winter?
    I see someone else was asking for temperatures. Any chance we could get you to put a thermometer in the opening for a few minutes? I bought a little 5 or 10 dollar jobbie at wal-mart or lowes that measures humidity, but it also keeps the highs and lows for the last 24 hours… i check it to see how cold it got the night before (inside my ecobox).

  6. thanks for your enthusiasm. i have seen a version that uses 3″ flexible aluminum duct snaking around the interior of a window box. This design was automated in that it turned on a fan when the temperature reached a certain degree. It seemed easier to make and relatively inexpensive.

  7. would love to see a heat measurement – a 30 dollar unit at the hardware store works well (for lots of different things) or just a thermometer. Having watched a lot of these vids online, and constructed a couple prototypes myself, it seems that we all need to figure out the best/easiest/cheapest/simplest materials and come up with a basic plan, that won’t freak out the neighbors, is easy to setup and move, and then go to town. $2000 invested in this will outweight 10x that in solar photovoltaic.

  9. i cut a 4 inch circle hole in my wall and put a dryer vent into the house…facing the south..for the most efficient use of sun energy put the pannel on a southern facing wall at your lattitude plus 15 degrees…..
