Bending Metal Conduit for Green Houses and Inflatable Green House Walls

 

I was over at a friends house a while back checking out his green house and he gave me a good idea. I had always planned to use metal tubing for the greenhouse frame (electrical conduit or chain link fencing top rail) Conduit is cheap and strong I use it for trellises already. Anyway The roof on his green house is inflated  sort of like those bouncy houses for kids.  Which offers more strength and better insulation.  So I did a little research because I had seen some inflated forms that people used to make concrete domes that were similar and I thought why not do the same with a green house for better insulation any way I found you can seal up seems or weld greenhouse plastic together with an Iron and some wax paper or soldering iron.
My Friends roof has to have constant pressure with a pump like a bouncy house but I thought why not have a sealed section with a valve so you can inflate it like an air bed and it stays inflated and maybe have to add a lttle air once and a while but no constant pressure needed.  So I plan to experiment with this and will let you know how it works out.
Anyway here is a video of how to bend metal tubing:

And here is a site with more info and videos on how to bend the tubing. They also bend a peak into the tubing to make a parabolic or catanary arch which is stronger and sheds snow better. (One of these days I am going to build a concrete house this shape) 😉

Here is a site on making inflatable bladders of course this is just a small one but could translate to green house size: http://www.rusticgirls.com/how-to/inflatable-bladder/

Welcome to BecauseItsTime.com! A Vision of Our Future…

Welcome to BecauseItsTime.com!

This website is dedicated to building a better self reliant sustainable society and providing a model for future communities and society. You may not agree on everything and that is ok, however I think we can all agree that we must do better and that we can. Why? Because it’s time!

Creating a Better Society

I have had a vision for a long time of a better society. A more decentralized society, a more self sufficient society that cares for the environment yet embraces technology but is not dependent on centralized energy, factory farming, manufacturing, food distribution etc.

Think about it. How is it that in the 21’st century if the power grid goes down for any number of reasons millions will instantly be thrust back into the 19th century? Refrigerated food will rot, people on life support will die, people will freeze or over heat etc. It is just insane  that we have become this vulnerable in this day and age and there is no reason for it! If we were able to produce energy more as individuals and local communities we become much less vulnerable. That’s just one example.  Centralization  of resources and distribution makes us vulnerable if something happens it can effect the entire country.

I know things are not going to change over night however it has to start somewhere!

With today’s technology there is no reason we need to be trucking food picked green thousands of miles across country. With passive solar Greenhouse technology literally every state can no grow anything they currently import.

We are at the mercy of the oil and energy cartels when we have had the technology for over a hundred years to be energy independent. With bio fuels like ethanol, bio diesel, bio or methane gas, wood gas etc we could have been independent decades ago. Its renewable clean and efficient.

Some will say if that were true it would have happened. Well I am not going to argue these points in this article suffice it to say don’t believe every negative thing you hear or read about alternative energies especially proven technology we have had for over a century like ethanol methane and other bio fuels. This does not even include emerging technology for alternatives like hydrogen, fuel cells, LENR, and magnetic motors etc. Let’s just say “some special interests have a vested interest in keeping the status quo since they make billions off it and if you think they will not go to great lengths to keep their hold on energy markets well then I don’t know what to tell you. Lets leave it at that. Don’t get me wrong I don’t hate big business in general or especially entrepreneurship however a few of the politically connected have harmed us and the environment with out regard for anything but their profits.

Many people are realizing there must be a better way. However they have little idea what to do to help us get headed in that direction. Many feel hopelessly stuck knowing there is a better way but frustrated that others do not seem to care or are even aware.  That is what this website is all about. Let me just say it starts with you with each of us. If you’re reading this you are probably one that is frustrated. Well you have come to the right place. Dare to dream! What the mind can conceive the mind can achieve!

Imagine 

Imagine for a moment when you need a car or a TV instead of going to a store or dealership you order it on line choosing the features you want and then go to the local library where it is printed out on a 3D Printer? Sound far fetched? check it out: http://www.newscientist.com/special/3D-printing . The technology is here now and being used. Imagine living in Minnesota or Idaho and buying home grown oranges or avocados grown right there in the state? It is easily possible with passively heated greenhouses called a “Walipini” or similar greenhouse technology. They are green houses similar to an Earth Ship but with what is called a cold pit in them.

 Have you heard about the guy who grows a million pounds of organic food a year on 3 acres using aquaponics? He’s is the largest farmer in Wisconsin on 3 acres mind you. That is simply amazing! A Million Pounds of Food on 3 Acres! The vegetables and plants grow two to three times as fast and only uses 10% of the water used to grow them conventionally. This is a near perfect marriage of technology and farming in a healthy sustainable symbiotic relationship.

Solutions

It’s easy to complain it is always harder to come up with solutions. Here’s some main points and solutions I jotted down:

Problem: petroleum based factory farming is unsustainable and ruining the environment and our health with synthetic fertilizers, pesticides, and GMOs etc. Most food travels an average of 1400 miles to get to our tables. Which of course uses a ton of energy too.

Solutions: We need local/regional food production. Aquaponics, and green house technology can save us energy, increase yields and use less water with vastly less travel to our tables. It needs to be natural, organic, heirloom, and non-hybrid as much as possible. Nature has spent millions of years developing and evolving the fruits of the earth and our bodies have also developed and evolved on those foods so natural is what is best for us.

Problem: Oil is peaking (not running out) as far as production meaning we produce less then we did 30 years ago but demand is higher and increasing. The low hanging fruit (easy to get oil) is much less now days (we have got most of it in the last century) and shale and other means is harder and more expensive to get and process so prices will be going up while production continues to decrease…

Solutions: Ethanol, Biodiesel, methane, and wood gas/gasification etc. all need to be ramped up along with research into alternative energies such over unity devices etc.. They also need to be done locally and regionally not using the gasoline model with centralized processing plants trucking fuels thousands of miles or they are not as cost effective. However the idea they don’t put out as much energy as they take to produce is a myth put out by big oil (more to come on that in other articles). We will have to cut energy use while in transition and learn to be more frugal with its use all around regardless and even if we stayed on oil.

Problem: we waste tons of water. Ssewage and water treatment plants are not sophisticated enough to filter out exotic all chemicals that we consume in medicines and food like caffeine etc. and they are showing up in the water supply now. Water use is increasing exponentially and our aquifers are not being replenished as as fast as we are depleting them in some areas.

Solution: we need to compost our manure and collect and filter rainwater locally and individually. 1 inch of rain on 1000 square feet of roof is 500 gallons of water. Nature brings water right to us but we let it get away and then have to expend lots of energy to get it back out of the ground when all we need to do is collect it right were we live.

Problem: Credit based fiat debt system is completely unsustainable and could implode at any moment and we see the effects already with the 2008 crash and we are heading for a bigger crash.

Solution: Sound or hard money such as gold and silver and local currencies that are backed by precious metals or commodities. Not leaving it in the hands of government anymore. No more credit based currencies and no more fractional reserve period!

Obviously there are more  and this just touches on things however these are some of the main ones. We need a movement toward a new society model or at least we need to create one for others to emulate IMO…
