My passive heating system.
This is just a fancy name for a device designed to utilize the warmer temperature in the lower strata of the soil, to
let it rise and help keep the temperature in the shelter up. (See: http://www.bananas.org/f2/permanent-banana-shelter-winter-spring-17855.html)
This post is meant to present a pictorial explaining the assembly of my devise. Many of the explanations are
included right in the photos.

This first photo shows the assembly of the support skeleton. Because it will be subject to considerable soil pressure,
I deemed it necessary to install braces at half depth. Unfortunately 4-way fittings as would be required here were
not available. I used pieces of a ½ inch dia. handle of a stir spoon used for wine making. The alternative would be
using another set of ¾ inch tees. But it would probably be easier, cheaper and cleaner to buy one stir spoon from
your local wine making store. So far the use of PVC pipe cement was unnecessary

This photo shows a large magnification of a snippet of pet-save fly screen. That stuff is extremely strong and
durable and has the advantage of being PVC coated and thus directly fuseable to the PVC skeleton with PVC
pipe cement.

Make sure, that you also wrap some of that fly screen around both ends, apply more PVC cement if and where
necessary and, viola, you have a highly sophisticated passive heating devise ready for installation. :ha:
I will write more about the installation, which I did in conjunction with my experiment on non-destructive
propagation of E. Maurelii.
