Jim --- Good point --- every little bit does seem to help! We don't have solar air heaters, but do have a huge bank of windows on the south side of our trailer, which provides lots of passive solar heat on sunny days. We do want to add more thermal mass to that system eventually, but it's not on the list yet....

Nayan --- Good point on the metal rusting. Yes, I have seen a bit of rust on ours already in our wet climate. The goal of the height in our system is to allow us to use gravity pressure to run sprinklers to water the mushrooms.

IF you let the man in your life worry about these things concerning the house, structure, insulating, guttering, towers and so for you would be a much happier woman...left to do the things you enjoy the most. You are such a controlling woman...yikes.

Glad to get that off my chest....now I'm happier.

Hope to see Mark making His posts more interesting since you've given up making ALL the decisions thus giving him something to write about.

Something to think about girly....you don't have to post this up but I HAD to say it.

Edith

Anna, I'm surprised you felt obligated to post Edith's comment, but I commend you on at least resisting the temptation to respond to it. I won't.

My goodness, Edith, what a thing to say. Anna's ambition and determination, and her thoughtful sharing of her hard work and research on all kinds of projects, are inspirational to many of us, male and female. You appear to have some very antiquated notions of appropriate spheres for the sexes, which is your right, but I'm surprised at your unkind personal criticism of Anna. I was offended on her behalf, and on the behalf of many other people who don't share your views. I hope you will consider keeping such thoughts to yourself in the future.

@Nayan:

IBC are primarily designed for use inside (warehouses, trucks, production plants). They are generally made from a rotation moulded polyethylene cube surrounded by a (usually galvanized) steel frame. The base is a pallet that is made out of wood, plastic or steel.

When exposed to rain, the metal frame will start corroding after a few years. (you could use a sacrificial anode to protect it.) If you live close to the sea, it will corrode faster.

The polyethylene cube will suffer from degradation by UV light, unless a UV stabilizer is added. Possible signs of degradation include loss of transparancy and flaking.

My guess would be that in general the plastic will fail before the frame does, but that it should at least last around a decade in a moderate climate.

However it is impossible to give an actual prediction of how long an IBC will last outside, because that is very much dependent on the circumstances. What we can say though is that keeping the IBC's frame dry and the plastic out of direct sunlight will prolong its useful life.

It would be a good idea to empty it in the winter to prevent frost damage. Another factor is how to keep it clean/usable. If you collect rainwater I suspect that in time you will get algae growth inside. Keeping the container covered to starve them from sunlight will slow their growth.

Heather,

Not all woman are feminists....my ideas are alive, and well with many woman sharing them....:o). Only thing is most don't have the courage to speak out for fear of ridicule or being told to keep our "politically incorrect" thoughts to ourselves. Many terrible things have been done by this means.

Truth hurts sometimes but truth is not unkind. Criticism is a healthy thing. I for one want to know how others view me so I can make sure I am not controlling which is a female tendency.

No one can say or do anything to offend another. A person "takes offense" at whatever is done or said. This said.....your offense is of your own making not mine...:o)

I have been reading this site for a long time so I can see.. what many others can see.

I wonder how Mark feels about it? His posts pale in comparison but what can he write about?????

My intentions were not to hurt but to show how she comes across to many woman. It's an insult to see a strong man over shadowed by a feminist woman. It's very sad how it's destroyed the traditional family. We have very few real, strong, confident, men left. They have been destroyed, and subjected to feminism.

It's all very though provoking is it not?

Edith

Okay, I did post Edith's second comment, but I'm going to ask people not to respond. I don't think this issue is worth debating on a homesteading blog.

Edith --- You've had your say and are now repeating yourself, so I won't be posting further comments from you on this topic. However, feel free to post on-topic comments on homesteading issues like growing food and becoming self-sufficient.

Troll?? You have got to be kidding..

I know you won't post this but it just proves my point. I did not repeat myself in the second post, I explained the first one.

It's your life but it's quite sad to see.

Edith

I commend you for taking on these projects. We also tend to over think and over engineer projects. For us the over thinking is a result of us renting the property we are working on. Everything has to be transportable in the event that something happens and we have to move the chickens, coops, rabbits and raised bed gardens, etc. I feel the other part of this is that we see the shoddy workmanship and know we can do it better, make it last longer, make it more aesthetically appealing and functioning but I feel the biggest thing is it is OURS and we want to do it right. A case in point for us, is when building the coop (15x10) and run (15x35), we added an extra door a few feet inside the main door, this allows us to enter the coop with new bedding, food, etc without having to chase the girls around the yard. We have too many predators here between the hawks that sit over the top of the enclosed coop/run and coyotes and loose neighborhood dogs. Keep up the great work and don't worry about over thinking/engineering things unless this paralyzes the project!!
