hmm seems like a good idea. Wouldn'y you need to replace the cold airr for it to keep working though?

Stuff like this is all over my house... My garage door opener is ziptied to the ceiling bc the ceiling was too low to install brackets.

You mean the motor drive is zip tied to the ceiling? Those things are heavy!

yeah it is lol... I have 2x 1' L brackets screwed to the ceiling and then six zipties connecting it. Ghetto, but it's either that or manual door. No1 with a license was willing to install it cause there wasn't enough room.

Pretty cool, nothing spectacular though.

The sun beats on our garage door almost all day. Temps on the back side of the door would be around 140ºF. During the winter, I set up a fan to blow across the back side of the door. It would heat the garage up by 10-15?ºF, which was pretty nice.

It kinda sucks now that its summer, though.. Gets hot in there, no fan needed.. lol.

Edit: His setup would be much more efficient even with a small, solar powered fan put into the setup.

so temp coming out was 105F.
but what was the original air temp?

I dont think that outputs enough BTU/hr or kw/hr to heat up anything...

Fuck threads that talk about heaters on 90f days. Im die'n here!

I bet it puts out about 1000BTU/hr. Not much, but completely free.

Figure it has about a square meter of surface area. The sun delivers 1000W/m3.

It probably generally sucks, so I figured about 300W == just over 1000BTU. Just wild guesses though.

Why would he bother drilling the cans when he could simply punch them through?

But, but, you are the SunSamurai!

BTW, it's currently 100F here... :sun:

I really REALLY doubt that - his window is about a square meter or so, which would mean it's ~30% efficient at recovering solar energy at 1000BTUs/hr.

No way that's possible, especially using air as the thermal conduit.

Since this thing is getting all of its energy from the Sun, couldn't he just have used a flat piece of metal painted black? It seems the only thing you really have to engineer is a surface that's painted black so it absorbs as much sunlight as possible. No need getting fancy with it.

Yeah, that's generally how its done.. but I guess soda cans are "free"..
