RE: [papercreters] UG Dome

OK, I am in agreement that mold can be a big problem with earth tubes.  Just how effective would be a combination of swabing with say a bleach solution and an ozone treatment?  There are no free lunchs, but we can evolve into a pretty ecologically sound alternative Thanks Bert --- On Fri, 2/27/09, Nick Boersema <picknick@sympatico.ca> wrote: From: Nick Boersema <picknick@sympatico.ca> Subject: RE: [papercreters] UG Dome To: papercreters@yahoogroups.com Date: Friday, February 27, 2009, 6:31 PM I would recommend any one thinking of earth tubes to look at Don Stephens work http://www.greeners helter.org He has a lot of theory on his page and some really good updates on the old technologies of the Seventies.  I do wish he would update his site more frequently with new data form his customers that have been using his ideas for more than five years.   Nick   From: papercreters@ yahoogroups. com [mailto: papercreters@ yahoogroups. com ] On Behalf Of Greg House Sent: Friday, February 27, 2009 11:41 AM To: papercreters@ yahoogroups. com Subject: Re: [papercreters] UG Dome   Spaceman wrote: > I'll run a few earth tubes for the air intake so I stay at ambient more or less. Do you have any experience with earth tubes? I've found a lot of contradictory information about their effectiveness and am wondering if it's really a viable technology or not. It -seems- like it'd be workable, but nobody seems to have information about how deep they need to be, how long, etc. I found one website that had all these intense calculations about airflow, ground temps, etc which sounded very positive...but then they went to say they'd never actually BUILT one. Great, that's real helpful. Other sites say the ground around the tubes gets heat saturated and they stop functioning after awhile. So I'm confused. This is something I think I'd like to use, but it's a lot of work and money for all that excavation if it doesn't function. Greg
