Will update after the next Staff & Volunteers meeting in a couple of weeks, should have 3 - Sewage Treatment, available after that.

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.

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...?

Hello all -

I'm giving a short presentation Sunday, covering Principle 1 - Thermal / Solar Heating & Cooling.

I think I've got it mostly covered, but would appreciate any pointers if I've missed anything....

If the presentation is at all useful to anyone, you're all more than welcome to use it also (maybe once I fill up Principles 2 to 6 as well .....and it might be available in very, very broken Chinese too.....

(* 'Target audience' is Staff & Volunteers working on the '4 Person Eco Home' at the 2018 Taichung Expo, here in Taiwan.)
