Alex, Crispin, Hugh, Paul W., Dale, Christa, Tom and others,<BR><BR>I found
the document Alex cited about CO2 in greenhouses to be <BR>extremely
interesting.<BR><BR>http://www.omafra.gov.on.ca/english/crops/facts/00-077.htm<BR><BR>There
has been occasional discussion at BEF Stove Camps and elsewhere <BR>on
the use of larger TLUDs in small greehouses for both heat and for
<BR>CO2. With some proper CO and CO2 or O2 and smoke detectors to
provide <BR>safety features, the igniting of quality-checked large TLUDs
WITH FAN <BR>ASSISTANCE (to assure best combustion and to help with
circulation) <BR>would make great sense for small greehouses.<BR><BR>The
document gives some basic numbers that we could use for
<BR>calculations, but all the examples are for very large greenhouses
and <BR>using propane and natural gas. But perhaps the "number
crunchers" in <BR>our group could calculate the heat and CO2 from a
TLUD-FA with perhaps <BR>a 30 gallon capacity burning chips or
pellets. And then match that <BR>with a size of greenhouse in some
appropriate climate/temperature zone.<BR><BR>If safe and appropriate, perhaps
5 or more TLUDs could be prepared and <BR>(automatically?) ignited at
specific times through the night. The <BR>concept could be
scalable within the range of small to medium <BR>greenhouses.<BR><BR>If
interested, please respond initially via the Stoves listserv and
<BR>also to the addresses of this message. If there is interest, then
a <BR>working group could be created off-line from the
Listserv.<BR><BR>Paul<BR>-- <BR>Paul S. Anderson,

<DIV> Paul, </DIV>
<DIV> How soon do you want to start the experiment?
I am taking possession of five acres tomorrow through a lease purchase to build
a new plant nursery. I have little time to rebuild my entire little greenhouse
complex this fall due to the urgency of my forced business relocation. </DIV>
<DIV> My plan is to quickly construct one or two small
greenhouses in order to preserve my tropical plant collection and start some
annuals for next Spring. Next summer I hope to reconstruct the large greenhouse
bigger and better than the old version you saw decaying a few years ago. </DIV>
<DIV> Any and all ideas for collaboration will be
considered. Until the entire site is excavated and sub drained only small,
portable, temporary structures will be constructed. I have considered purchasing
one of Tom Reeds larger camp stoves for experimentation unless someone has a
donation TLUD stove. I am on a limited budget while restarting my landscape
business from scratch. Ideally I need a stove that will burn slowly unattended
all night. </DIV>
<DIV> Plenty of fuel will be available from clearing the
site as well as my small firewood selling operation. I had well over 30
cords of small trees sitting stacked around a friends farm
in northwest Miami County last Spring. I bet most of it is still there for the
taking. </DIV>
<DIV> Anytime you are driving through Dayton please call
and arrange a visit to my new site. It's only a mile from I-675. Less than
5 miles from I-70. The new site will be very unimproved and
primitive for some time, bring boots. </DIV>
