I tried to attach, but it told me that that file type wasn't supported.
i don't currently have an account at another storage site.

it seems to me that  the  most important part of considering energy independence is a proper evaluation of energy wants vs energy needs and a reorganization of priorities to accommodate what energy one can maintain independently.
for the most part we have forgotten how to live within our means.  to do so with money leaves one in financial debt.  to do it with energy and food, i believe, leaves one in a similar situation of debt.

refrigeration is probably the biggest problem.  our entire  society has come to depend on it.  in the past, my family used to buy eggs and dutifully keep them refrigerated.  we have since learned that fresh eggs from one's own chickens last far longer that store bought eggs even without refrigeration.  which made me realize just how long it takes to get our food from source to store.  meat is similar.    fresh meat will keep longer in various ways than store bought meats.    the trick is harvesting on an as needed basis, which requires one to know this process.  i've learned the process for chickens, my wife does pretty good at processing feral hogs.    the processes from there are similar, just the scale of the tools and  setup may change depending on size.

all of the methods of self sufficiency from the past are rather limited now.  I don't think there is any way we could all revert to old ways without completely rearranging where and how we all live.  
I am starting to believe the Industrial Revolution hurt us more in the long run than it helped.

how about a gasifier to run a generator?  is that taking it too far?

I had a wonderful daydream that went something like:
gasifier -> generator -> pellet mill

when we had unexpected negative temperatures here this winter (a bit further south than oklahoma), all of the gas stations shut down.  no gas.  no diesel.  nothing to run a generator on other than what might be kept on hand and rotated.
as much as I knew that was always a possibility that there would come a time when the fuel supply would shut down, I didn't really expect it.
but i've got trees in abundance.  If I wanted to get serious about going only RMH or gasifier, I would start coppicing trees.  heat and cook with RMH / Rocket stove and electrify with pellets.

are you opposed to using a Polyethylene Plastic drum liner?

I read an article some time ago about the making of bois d'arc hedges for fence.  
I cannot remember where i saw this, but the basics of it went:
settlers spreading out across the US would take with them bois d'arc saplings to plant when they arrived at their destinations.
the idea was that they would form a fence with bois d'arc grown very close together that they described as "bull tough and hog tight."
the process involved collecting bois d'arc fruit (we always called them horse apples)  fill a barrel mostly full with them so that they could be covered with water and allowed to stand then freeze and thaw a few times over the course of a winter.  in spring time, the barrel would be mashed and stirred into a slurry, releasing all of the seeds.  the resulting slurry would be poured into a shallow trench along where the fence line needed to be.  eventually the plants would grow into an interlocked, tangled thorny hedge.

having dealt with stubborn animals that refuse to recognize the authority of various regular fences, I have been wanting to give this a try.  just as soon as I can collect the fruits that I need before the squirrels get to them.

can you share some of the drawings?
I like the idea of the spiral stair around the bell.
my question is, though, is  the bell going to be attached in any way to the treads of the stair?
as in, is the bell supporting the stairs, or are they just running around without contact?

I guess its just a mechanical interest on my part, I was thinking the heat might eventually weaken the metal bell and interfere with the stair.
If the bell were made of sturdy enough material, then metal stair treads or tread supports might even act as radiator fins to help disperse the heat.

in the areas of permies that I regularly browse, I see lots of people using Sketchup for 3d visulaizing their ideas.  I don't know if Sketchup is free any longer, but I do know of a highly capable 2d drafting app that is free.  it can also do some basic 3d work.
it is called Draftsight, provided by Dassault systemes.  these people also make very high end solid modeling and simulation programs.  the draftsight product  itself is natively based on the AutoCAD dwg format and is in most respects almost identical to Autocad with differences in some features and command names etc.

there are many such programs out there, but this one is by far the best in my opinion.  i have been in the past a CAD manager for a large architectural firm and have used autocad for decades.
the only reason I haven't switched away from autocad is that the  companies I work for do work on government projects and for others that require autocad specifically.
probably the best part of this program is that it is available for windows, LINUX and mac.

I guess you could do it as well.  I went from this link:

there's a link inside to get meshlab (free).  the trick was to make a single mesh rather than put multiple on separate layers as it asked me about.
model wise, the conversion looks a bit dodgy, but it worked.

Scott Weinberg,
I have solidworks and version 15 of sketchup.

I think it's a bit buggy, but I did produce a sldprt file.
if this works for you, then I can do the rest.

we may have version problems if you aren't on current solidworks though.

aaaaaaand, I don't know how to share this file  and I can't remember where I saw a post on how to best do so in these forums.

keeps the hot side hot.  
It makes sure the heat stays in the riser to encourage a complete and most efficient burn.

perhaps not exact, but pretty darn close I bet...
