Point well taken. I guess what I meant was a shape that would allow more
mass in the same footprint; all the empty space that the circular barrels do
not fill in between each other could have been filled with water for more
heat storage (and release) -

to my understanding you want the thermal mass to 'loose heat' - this
is what keeps the temperature up in your greenhouse. if heat is just
stored but not relesed into the surroundings (inside the greenhouse),
they are no good anyways.

Permaculture TV - State of the USA Organic Industry - Dr Phil
Howard, MSU<http://permaculture.tv>
<http://www.msu.edu/>I teach undergraduate and graduate courses in
Community, Food and Agriculture, as well as a graduate course in Research
Methods.
My research focuses on the food system. The food system involves all of
the steps required to produce food and get it to our platesfrom farming and
processing to distribution and consumption. My work is unified by three main
questions:
[image: Processing Animation - Consolidation of Organic
Processors]<https://www.msu.edu/~howardp/organicindustry.html>
Processing Animation - Consolidation of Organic Processors
- What changes are occurring?
- What are the impacts of these changes on communities?
- What can communities do to respond positively to these changes?
..
*I currently have three main projects:*
1. characterizing consolidation in the food system, particularly in the
rapidly growing organic sector
2. exploring inequalities in food environments and their potential
relationships with health outcomes
3. studying consumer interest in ecolabels as a potential strategy for
improving the livelihoods of small- and medium-scale farmers
