It is official, I have shelter, a dome...thing. It is a nylon material.
@ 20x20, 9ish feet tall in the center
Three smallish doors that zipper, no mesh.
Clear plastic windows that have covers (with pockets = awesome).
There's a round hole at the top, no mesh. I'm wondering about putting a fan up there, to pull air up and out.
It has holes all along the bottom, that I was thinking I need to close up. They're like...drawstring, and can be pulled shut, but not 100% totally.
Or leave them open to help circulation with the fan pulling out hot hair...
I am also wondering about the rain fly. I won't need it for rain. Would it make the heat worse by adding another layer or provide some shade?
I recalled reading somewhere about using the shade thing on the outside to create some sort of layer of air, or keep the hot air a layer off the actual tent...but I can't find what I was reading.

Re: Keeping a dome cool...
Fri, August 21, 2009 - 8:09 AMThe ventilation holes, top and sides, are meant to work under the rainfly layer/ the rainfly keeps direct sunlight off and provides an air sandwich to insulate. You need to open all vents, and have the rainfly in place. this will make a cooler setup than the inner liner opened up in direct sun. Try it with and without to see what it's about.
No doubt a fan directed to pull hot interior air upward and out of the top hole will help the process along. Don't point the fan to blow downward but to draw warm inside air upward and out. -

Re: Keeping a dome cool...
Fri, August 21, 2009 - 8:58 AMTo clarify, rain fly was probably the wrong word. It is a piece of fabric that sits on the top, doesn't cover the whole thing.
I don't think the link for pictures worked in the OP:
playabound.wordpress.com/2009/...-dome/
So I will definitely put it on, then, for cooling...should I throw some more sheets on top or anything? In my head that just means keeping heat in, rather than providing shade (as opposed to a free-standing structure around it, which would just be shade...
I'd love to leave all vents open, at least while I'm in it, but I'm under the impression I should seal it up, when I leave, in case of dust storm? -

Fri, August 21, 2009 - 1:20 PMshade cloth works wonders. not sure if there's still time to get it shipped prior to this year's trek. there's a number of websites out there, and the stuff ain't cheap but it really, really helps

Re: Keeping a dome cool...
Sat, August 22, 2009 - 9:39 AMThe thing you want to see happen is that air gets in under the fly cover and that might mean having to roll it up twenty inches at the bottom all around to get that nice air circulation going on. Maybe held up rolled with clothespins or other small clamps.
If you want to add to the shade potential for cooling purposes, then a silvery reflective tarp fabric would do it best.
As to the dust storm thing, you need to seal things down to keep that out... the downside being that cooling ventilation won't occur. Lots of people say to heck with it and live dusty ---rather than less dusty and plenty sweaty. You choose.

Sat, August 22, 2009 - 6:29 PMIf you really want to keep cool, mylar is the answer. Just secure it firmly to a solid surface and watch it reflect away the heat. It's wonderful!
