Anyone ever tried a thermosyphon type of thing with the hot air from e.g. the glazed frontage of an earthship or glazed passive solar thing?

I'm looking at Solar Chimneys etc at the moment, and wondering if this would work.

Ducting roughly man-handled into place on this drawing!

Downpipe at rear of room could be in cob or something I guess.....and ducting could be hidden / insulated...?

You would need a fan to move the air.  The warm air is at the highest point of the piping, and so will just sit there.  

Actually, I just looked at the picture again.  I didn't notice the slope to the ceiling on the wall side.  You should get some air flow that way.  The problem is that only a certain amount of light/heat comes in through the window, so you aren't getting any more heat than you get through the window itself.  You are circulating the air somewhat, but a small fan would do the same thing.

Thanks Trace.

I wasn't sure if it would work at all.

That room is very open at the moment, maybe convection would be running okay.

Perhaps ducting would be more beneficial if / when partition walls are in place.

And maybe with a small fan.
 
Oh, sure, you could do that. Or you could eat some pie. While reading this tiny ad:
