Disasters are never fun and neither is having your daily routine upset in order to survive one. It can be stressful and full of things that can go wrong.

I’ve been checking out a variety of blogs and websites advocating a variety of ways to survive a disaster. Most people who prepare for a disaster tend to follow textbook advise by supplying themselves with modern conveniences and technology. For a short-term disaster that is often fine but not if it should last six months or more. What do you do then?

Here is an example of what someone might do to prepare themselves:

Buy a diesel powered electric generator, either a tracktor or plow and stock up lots of canned
food and other personal care items. So along comes someone who didn’t prepare but has weapons and takes what you have which took you so long to stock up in the first place. Then what?

If your scour blogs like I do you will come across those people who advocate that you militarize yourself with weapons and follow military survival techniques. Although helpful will not help you survive if there are also other people competing for the same resources in which case you both fight it out until one is dead, one gives up or you both decide to work together. That’s a lot of wasted energy and it only perpetuates the very mindset that created the problems in the first place.

Here is why I don’t recommend following prescribed plans for surviving a disaster:
For all modern things that require a liquid fuel such as a generator or tractor need a huge supply
of liquid fuel which means a large tank to hold it. Eventually you will run out then what?

Then people think about getting a plow and an animal, horses or buffalo to pull the plow which requires a large amount of feed (namely grasses and other plants) or large enough field for them to graze in. Don’t forget you have to train the animals and yourself too. That only adds to the work needed.

Instead here is what I recommend:
I say do away with conventional thinking and do the work yourself in small manageable sized plots. Figure out how much you can work in a day then figure out how much you need to feed yourself and that is the amount of land you need. Masanobu Fukuoka – a Japanese Permaculturist – said anyone can feed themselves on a quater acre by following his [permaculture] principals.

It is actually not that hard to feed yourself by building a quarter acre food forest which grows a large variety of edible plants which has built in resiliency. What does that mean?

When the potato famine happened in Ireland it wiped out the single type of potato they grew. If on the other hand they had grown a variety of potatoes like Peruvian people do then they would have survived the potato famine because not all of the potatoes would have been effected. That is what resiliency is about. If one thing fails not everything fails that means you don’t fail either.

So, if you are going to prepare yourself to survive a long-term disaster, which means you can also survive short-term disasters, you prepare yourself in such a way that includes resiliency in your plans. It also means not relying on any modern techniques, machines, technologies and so on. That way if someone with weapons should pass your way you stand a better chance of surviving because you don’t have anything worth stealing.

I have been working for the last month very hard to find gainful employment and I have come to the conclusion that there is none. It no longer exists and we are not out of this continued recession, depression. In my book, Recession Survival Guide self-published in 2009 I said it wouldn’t be over before 2015. Now it looks like it will never be over. Anyone who thinks they are being told the truth by the news owned by the companies that manufacture the news is dumber than shit and ought to be composted. At least that would create something of value. The U.S. has an enormously large number of dumb people as compared to other industrialized countries. Reagan even lowered the I.Q. scale by ten points to raise the national I.Q. level.

The future on the current path looks very bleak. I have to back up for just a moment before going forward.

Robert Hayes who likes to comment on everything I post followed me from Facebook where all he did was post negative shit and now he is here doing the same. Here is my response to one of his comments he posted – a quote from Wikipedia:  “Peak oil is the point in time when the maximum rate of petroleum extraction is reached, after which the rate of production is expected to enter terminal decline. Every oil well and field exhibits similar characteristics of being discovered, the logistics to extract the oil being put in place, a peak or plateau of production, followed by a decline.  US domestic oil production peaked in 1970. Global production of oil fell from a high point in 2005 at 74 mb/d, but has since rebounded, and 2011 figures show slightly higher levels of production than in 2005, as the definition of “oil” was changed in 2007 to include synthetic liquids.”   [http://en.wikipedia.org/wiki/Peak_oil]

So yes, the world oil production has gone up only because of fuzzy questionable bookkeeping not because there was anymore oil found all of a sudden which had peaked in the 1960s. We have only found less and less oil fields and wildcatters are coming up with more dry wells each year. Robert Hayes only finds enough information to support his point of view and doesn’t spend hours reading or cross references to see what he is saying is factual or supportive.

I say all this to show how so many people keep saying that we have lots of oil left for(ever), a long, long time. Discovery peaked in the 1960s and the entire planet has been surveyed so the question is where, or how, are people finding “new” oil. It is scientifically impossible.

So much for that.

The closer we get to the end of cheap fossil fuels the fewer choices we have or time left to act. Former president Clinton, Matthew Simmons an energy investment banker and adviser to George W Bush, and Dick Cheney all have said in one form or anther that we are running out of oil. Whether directly or indirectly stated we are on the downside of the Peak Oil curve and headed downward at an alarming speed. As Cheney said, “That means by 2010 we will need on the order of an additional fifty million barrels a day.” That means replacing that which we have lost due to decline. There has been plenty more people in the last decade that have come forward to say the same thing from former geologists, oil explorers, and people who worked with oil production information (like the U.S. Energy Dept.).

No one agreed when Peak Oil will or has happened. That doesn’t matter so much as it will, or has and we are doing absolutely nothing to prepare for no more oil! Technology will not save us like some white knight or some savior, they don’t exist. Technology is utterly dependent on cheap energy to work or for its production. Without oil absolutely everything collapses. Do a mind exercise and research to find something that isn’t dependent on oil in some way or another. (I’ll give you a hint: You find a single thing that isn’t dependent on oil.)

I am afraid this country is being pushed into a Mad Max scenario where people will fight over whatever scraps they can find.  In the book, Raising a Nation of Whimps by Hara Marano, editor-at-large and the former editor-in-chief of Psychology Today, has been watching a disturbing trend: kids are growing up to be wimps. [from Amazon]

People in the U.S. have little or no backbone or character worth acknowledging.  That said I have come across some very remarkable people but when it comes push to shove many of them would whimp out.  Too many who would give in to anyone doing violence.

What does the future hold for us. Nothing good. There will be those who will know how to grow food, process fiber and produce enough energy for their needs. They just lack the ability to defend themselves against the people who would rather steal what they need than produce it on their own. My wish that everyone learn to defend themselves, be able to produce what they need, create a strong reliable resilient community in order to survive the decline in cheap and once abundant fossil fuels. It will be through these communities that people will be able to not decline to far into a dark age and find solutions for a real sustainable  future based on the principles Nature has set forth where there is no waste, everything has worth.

My mantra has become: Learn to grow food & fiber. Learn to become energy independent (that doesn’t mean using only trees for fuel or you will see a localized Haiti effect).

My last post asked what will happen with people who have a disability and I got exactly what I expected no reads and no comments. That speaks volumes.

I a very short time I will have to take a dead-end job just to pay the bills because Not the governor of Colorado not any city I contacted here where I live care about creating any sort of transition plans or real sustainability, durability, resilience policy. It seems the state I live in could care less what happens after cheap energy is gone and that will happen soon.

A now former CEO of Shell just a few years ago predicted we will have $3 per gallon gasoline by 2010 and we did, and do.  He also said to expect by 2015 the price to be $5 per gallon of gasoline.  We are heading that way and I have no doubt we will reach it.

Former president Clinton said in more than one speech or interview that we were headed for Peak Oil soon.  That was in 2006.  He also gave a deadline of 2030 as the year we can expect to run out of oil.  He may have let the cat out of the bag.

Here are some links.  You decide for yourself.

At this point the U.S. is fu–ed.  There isn’t enough time to do anything really so here are my suggestions:

  1. Get some land, even within a city.
  2. Reduce your consumption of energy by super insulating your home.
  3. Learn to grow food and save seeds from one year to the next.
  4. Connect with people near you, within walking distance, to barter and exchange whatever you need.  This would include skills.
  5. Learn to grow fiber, process it and make cloths or whatever else you need. Also learn to grow dye plants.
  6. Grow some plants for easy fuel like sunflower for oil to burn in a lamp. Honey bees for honey and beeswax. Grow your own fuel.

That’s it people.  The other option to fight and defend precious resources is not the answer because those who rely on war and violence will die at some point when they can’t steal anymore because the people who know how to grow food, fiber and fuel will live far enough away for violence to reach them.

The future will change dramatically and we are not prepared.

[ Sorry about the way this article looked. I am not sure what happened to the font. ]

Can we feed ourselves after the oil is gone?

This article is in response to an article in Permaculture magazine Spring 2012 issue, No. 71. The article,Can We Feed the World? Five experts give their views on the best methods of eco-farming, page 54 to 56.

These five experts each have their views with some cross-over. The five experts are, Bethan Stagg, Colin Tudge, Peter Harper, Patrick Whitefield, and John Ellison.

First there is Bethan Stagg who says we need to put into a practice techniques that take into account
local environmental conditions using intensification to get the most output possible. Saying it another
way, it is a type of polyculture farming technique.

Next Colin Tudge just says what I’ve have been hearing for some time now, we are growing enough to feed 14billion people but it all goes toward increasing profits rather than feeding people. Not completely true
as some of the food stuff are not meant for people but cattle or other farm animals because the grain has been genetically altered so people can’t eat it. He mentions the problem of wastage some of which can not be helped and that which can be helped should not be dumped but fed to people. People in industrialized
nations have been brain-washed into buying only the best looking and ignore blemishes or slight defects.
That needs to change.

Peter Harper talks about producing food in a post-carbon future. In other words, food production without
fossil fuels.

Patrick Whitefield is a strong promoter of Permaculture.

John Ellison and Bethan both agree that we can’t afford to rely on just one approach to solve our food
needs in the future.

They are all correct. We need to stop relying on mono-culture large factory farms and change the way we
farm altogether. This means we go back to the way we used to not too long ago. Also, we need to do away
with chemical inputs, tractors and so on to move away from oil and other fossil fuels, even biodiesel.

Based on their input and my views the answer to growing enough food is this:

  • We get away from the corporate farm and go back to many smaller farms.
  • We need to incorporate many approaches to grow the food we need.
    • Masanobu Fukuoka from Japan gave us no-work farming where there is no tilling of the soil, no
      fertilization, all organic and he has yields the same or better as farmers using tractors and
    • Sepp Holzer from Austria gave us poli-farming techniques. He combined fruit trees, herbs, grains, vegetables, hogs and fish all on the same land requiring again no equipment, no fertilization, and it is virtually self maintaining. He mostly spends his time harvesting and selling what he grows and does most of the work establishing his method and then there virtually no more work.
    • Polyculture at the most intensive manner possible geared to a local environment. This comes up in Permaculure in designing a Food Forest were in a small space you can feed more people than using traditional farming methods. Usually every three acres of Food Forest can feed around 8 to 12.
  • We need to produce food closer to where it is consumed. Places like the U.S. need to consume less calories overall, start by cutting the meat consumption by at least 50% the first year and again
    another 50% a few years later. Cows, pigs, chickens and other factory farmed animals need to be set free to feed the way they were originally intended, without hormones.
  • We need follow models like Cuba as a way to transition off oil and produce enough food for ourselves
  • The profit needs to be taken out of growing food, and feeding the people of the world.
  • Corporations like Monsanto need to be put out of business so food can again be put in the hands of

Everyone needs to decide what happens with their food, how it is grown and treated before it gets to theirtable. People also have to realize that for decades corporations (or governments) who have controlled their food have not had their best interests at heart only their own. That needs to stop. Our ancestors were either Vegetarians or near Vegetarians because they realized that it was a matter of survival and feeding an animal came second to their own survival. This meant that meat consumption was low.

Traditional methods of growing food need to be brought back and taught to everyone growing food if they
are to survive after the end of fossil fuels. Otherwise we will need to prepare ourselves, especially in the U.S., for food wars, riots, and uprising because people will want to eat and not know how to feed themselves in any other way than to steal it.

I might as well be honest, neither of these are something I would support and I thing we should not persue them rather we should be getting off oil as fast as possible.  Now let my explain why I am not a fan of either of these unconventional forms of energy, oil.

Tar Sands

Here is a partial list of some of the more glaring reasons why we should stop extracting oil from tar sands:

  1. Strip mining leaves the land destroyed for many lifetimes in the future.
  2. It uses millions of gallons of fresh water that is left polluted forever.
  3. It disrupts wildlife habitat for thousands of miles around, both in migration and in taking away their home by destroying it.
  4. It leaves huge, I mean so large you could not walk around, sometimes for miles very large waste ponds that poison the ground water and soil for a very, very long time.
  5. Any doubts about what I’ve said take a look at areal photographs of these ponds and the mining operation and it will become glaringly obvious to yourself the need to stop such nearly devastation to supply you with oil.
  6. The EROEI (Energy Return on Energy Invested) is a good measure as to how financially viable it is going after any source of energy or will it actually take more input than it gives back. As for Tar Sands the EROEI is only 1.5:1 or one-half more than what is input. To say this another way, if you get 15 barrels out you spent 10 barrels getting it. There is one flaw with this, it doesn’t take into account the millions of gallons of water that are poisoned, the land destruction, the huge amounts of pollution create and takes to mine as well as process the sand into an oil that can be refined.
    Tar Sands is an overall energy loss no matter how you look at it, because two other crucial figures are left out, transportation and refining it which then takes the energy return into the negative. There you have it.
    Why go after Tar Sands? It’s a last ditch effort with the help of  huge subsides to keep it going and to damn with all the environmental  protection laws and regulations. The U.S. is a huge importer of this oil from Canada. This impost of oil is a cover for the fact we are running out of oil.

Some people online and in papers they have published claim the EROEI is much higher, as high as 4 or 4.5 for Tar Sands. They are only using deceptive manipulation of the numbers to raise the energy output by ignoring many of things I have mentioned already.  Below I will post a link to photographs of the Tar Sands so you can see the total devestation that has been caused to keep you supplied (in the U.S. namely) with oil, gasoline, diesel and plastics (along with the millions of other products made from oil).

My advice, get off oil as fast as possible and shut down the mining of Tar Sands today!

Shale (the rock that burns)

The EROEI is even worse for Shale than for Tar Sands. You can literally superimpose the reasons for Tar Sands onto Shale. Huge mountains are turned into rubble in the process expending a large amount of energy to get nothing in return.  Let me go into a bit more detail and EROEI for Shale to oil and natural gas.

The amount of energy it takes to mine, crush, process, ship, refine Shale leaves it with no more energy than a baked potato.  Including the millions of gallons of fresh water left poisoned and the environmental devastation involved which leaves the amount of energy in Shale far worse than Tar Sands, in the negative numbers.

Here in Colorado where I live several mines were abandoned after several years because without huge subsides, tax dollars given to the companies they were never profitable to mine and process shale into oil. Both Chevron and ExxonMobile gave up leaving the mines as huge scares on the land.

The gas production from Shale is hard to estimate as we have no idea what it actually costs to get at the gas as it is a secret Haliburton is keeping.  Here is what is involved: Fracking is a method of injecting under high pressure and high temperature water and a chemical soup Haliburton claims is proprietary leaving the ground water and surrounding land poisoned. First, several wells are drilled into the Shale deposit. Then huge trucks are brought in with the chemicals and water if it is not available in huge quantities on the surface or by drilling. Both are heated and pumped underground to fracture the Shale and it is this fracturing which releases the gas. If the area sees a decline in gas production then the process is repeated with more clean water mixed with the chemical soup to further fracture the Shale.

People who live in the area where Fracking have found their well water becomes mixed with the gas causing it to burn. Also, the chemical soup leaves the water poisoned and undrinkable unless a person wants to commit suicide. natural gas is sometimes even found to bubble up from the ground which adds methane a greenhouse gas to the atmosphere. Haliburton has so far claimed no responsibility yet everywhere they have done this process the same results have occurred in thousands of wells.

With huge energy inputs to extract gas leaves me to conclude the EROEI is very low or in the negative. It is nothing more than a last ditch effort to hide the truth from people, we are running out of Natural Gas rapidly!

I suggest people find every which way to reduce your dependence on oil and gas as quickly as possible. Some practical tips: insulate your home to greatly reduce your energy consumption. For people who have some land, not within cities as restrictions would be greater, build an underground methane digester to produce enough methane for all your cooking needs cleaning and storing any extra for colder months. If it is at all possible build or convert your fireplace to a what is called a Masonry Stove in the U.S. or Kachelofen in Europe. It uses less wood or other materials and provides more heat to the home. Park your car or get rid of it and use public transportation or bicycle. Walking won’t hurt you either. Buy organic food and natural fiber clothing or as little petroleum fiber clothing as possible. Grow as much of your own food as possible, even apartment dwellers can do this it just takes ingenuity and a will.

The ideas are by no mean comprehensive but at least it gives you options that take you beyond oil and gas. The more you do the less you use which helps. Encourage friends and family to join you. Make these types of operations more expensive by not using as much as you presently do to the point where they have to shut down because they can no longer make a profit. Become energy independent, decentralize energy production and distribution are the only way to rid ourselves of our dependence on fossil fuels.

The Scientific American article, “Can we get off oil now?” dated February 28, 2011 has some very interesting points.

Too much of our oil we are dependent on comes from countries like, Africa, Middle East and Venezuela. (See full list of members of OPEC: http://www.opec.org/opec_web/en/about_us/25.htm) Many of these countries either have internal strife or they are not very friendly to the U.S. (they just like our money). Any of these countries could at any time begin the process of cutting off our oil supply and would we have enough money, oil reserves and troops to go after the oil?

The article says it well: “Eight of the top nine oil exporters are dictatorships or autocratic kingdoms, a control structure funded by our own dollars that is suddenly being shaken.” This was after the banking collapse and the financial crisis.

This paragraph brings home some of the hidden costs of oil most people have no idea exist: “The payoff of significantly reducing oil consumption would reach far beyond the economy and the environment, by the way. A study by Boyden Gray and Andrew Varcoe noted that oil companies are permitted under a waiver of the Clean Air Act to include known carcinogens such as benzene, toluene and xylene in gasoline, which raise octane (power output). The study showed that the added cost to healthcare and shortened lives in the U.S. comes to more than $100 billion a year.”

The article says what so many have said before: “To be clear, the goal is to break U.S. addiction to oil, not just foreign oil.” But how?

One solution is to get us off oil by transitioning toward liquid fuels that can take the place of petroleum is to implement a $1-per-gallon-gasoline-tax. This tax would be phazed in over time a nickel each month to give people time to begin finding alternatives, other options. This tax is the idea of Thomas Friedman who advocated that the tax go to lower the national deficit. Other people say the tax should go to fund new alternative fuels.

The RAND Corporation in a white paper they issued argued for a crude oil tax, “at the refinery, spreads the burden across all taxpayers, not just motorists and truckers.” Spreading out the tax would be more preferable, but then it would have to be significantly more than a dollar-per-barrel.

Another option would be to have two kinds of taxes, one on the crude itself and to help reduce car usage, and its associated health and other hidden costs on society tax both diesel and gasoline at the pump. Both could be fazed in over a period of a year at a nickle at a time at the pump, or in the case of crude, $5 a barrel every 3 months.

There is also the argument that subsides would have to phazed out just as the tax is being phazed in to make other options more affordable and desirable.

But, would this move us toward something better? No! Not necessarily. There is no gaurantee that something better would happen as corporations are known for taking short-cuts and doing what is in their best interests and makes them, and their stock holders, a profit. Here are my thoughts.

Hybrid and Flex-fuel vehicles are a joke. If were to have used them we should have started back in the late 70s and 80s. We need to move faster than implementing something that will take years to get them into the hands of the public.

Electric cars sound like a good idea but tell me, how much of that car is made with petroleum products? Did a light bulb just come on? Have never thought about this before? The answer varies slightly but around half of every car has parts that are made from petroleum. Here is a list: bumper, cloth covering the whole inside of a car, the floor carpets, all the hoses and belts, the battery casing, coating on the wires, lenses for all the lights, door panels, dashboard, seats, mirror housing,  knobs, switches, gauges, sound-system, ignition system, cables, computer, oil, lubricant, seat-belt, brake line, brake fluid, floor petals, anti-freeze, fuel line, steering wheel, and wheels. Did I miss anything? It really doesn’t matter because the point is, the car is able to move due to petroleum and is almost completely made from petroleum. So electric cars are out.

Hydrogen cars are out. Don’t even get me started talking about what a colossal waste in every sense of the word persuing Hydrogen as a fuel is. It is NOT a source of energy and never will be. It is an energy carrier. It takes more energy to liberate hydrogen from its bonds that you get out. Besides like the electric car it would be mostly made of petroleum.

Liquid fuels are a serious waste of money. We can make use of ethanol (not from corn) and biodiesel (from more than soy) to transition off of petroleum but we will never be able to grow enough to supply every car, truck, train, or boat with a liquid fuel. We would face a serious limitation in how much we can grow and still be able to feed ourselves. Liquid fuels from other sources, like coal or natural gas would face their own peak and quick decline soon after their introduction. Besides the idea is we transition off all fossil fuels in order to not be dependent of foreign imports any longer.

What does that leave? Some fringe ideas like cars that run on compressed air. This would actually be a good idea for the interim but not the long-term if we are to move off of petroleum. Running cars on compressed natural gas is another waste of our efforts. We would run out of natural gas in less than ten years if we had any significant number of personal cars using natural gas.

There is no single idea that will keep us all driving our cars, trucks, trains, or boats into the future. There are no alternatives. Don’t even mention algae because the amount of energy input (petroleum is used in lubricating the pumps, growing drums or membranes, tubing, pipes, filter, and some of the chemicals have petroleum ties) would be greater than the energy output. Algae is a lost cause. We should have worked on this one decades ago.

My solution: raise the tax as quickly as possible on both the crude and at the pump. Use the money to build an infrastructure of PRT transit systems, light-rail and both medium and heavy rail relying on electricity to move them, not diesel. Buses for public transit would disappear. Use the tax to set up a lab where brilliant scientists with not corporate ties would be given the task to find ways to mimic nature in producing plastics, along with other products, for the public transit systems. All items produced would have to be produced in such a way that at the end of their life would either be harmlessly returned to the soil or remade in some way so there is never any waste.

And how does this tie into growing food? Duh! 1) Farms would have to be divided up and made much smaller. 2) Food needs to be grown where people live and not transported. 3) We will need to rely more on natural fibers to replace all the petroleum based fibers. 4) The colors used in making cloths or for print work would be replaced with natural materials. 5) All farm equipment would have to rely on either electricity or biodiesel, but the farmer would have to produce it themselves and use it on the farm – no transport involved or the return on invested energy would go way up becoming unsustainable. 6) Nothing less than 100% organic everything. 7) The old systems would have to be allowed to crumble for this transition to occur just like everything eventually dies.

There you have it. I see not other way,  everything else but a direct heading toward complete transition off of fossil fuels as a waste of money and time. I would love to hear what you have to say so please comment.

There is a growing movement in Europe at the moment called I Don’t Pay! This post will be most controversial but it goes along with what I am trying to do with the overall Greenhouse Project.

We had Occupy taking over many major cities around the world. People camped out in good and poor weather to make a statement about the state of the world and the way things are being run. Even the major news outlets, blogs and websites keep taking about the 99% and the 1% and how the wealth has moved upwards. How it has been co-opted by few people for their sole greed and no social good has come of it. Phrases like, “too big to fail” have now become part of our lexicon and some have even said that they should have failed to help drag the top downward and broken up the “too big” into much smaller more manageable businesses.

Now I was sent a link to a YouTube video titled, Movement “I Don’t Pay” is spreading acrosss Europe (english subs) [ http://www.youtube.com/watch?v=tqeTGTU6FFg ] . The video is not even 5 minutes long and yet it has a powerful message, why pay for social programs. Why pay for things when the government subsides them? Why pay for something like public transit that gets government money? Why are people paying twice for things?

In the United States because our government offices at the state, federal or local levels don’t get audited or have to reveal where they spend their money we often don’t know how our tax dollars are spent or just how much a particular entity is getting. I suspect between the Occupy movement and the I Don’t Pay movement we are going to see much more information coming out to shine a light where there has been none.

Now I know what you are thinking, what does this have to do with food, food production, or the selling or buying of food. In the United States farmers, the big farmers, the corporate farms get huge amounts of subsides to either not plant crops, to plant particular crops, to manage the land as it is leaving it wild, or to produce a particular end product, like sugar. Food and non-food crops and end products are subsidized almost from seed to market, and in some cases they are when dumped onto the international markets.

When I came up with the Greenhouse Project I right away started wondering how can I produce food at the best price possible and even make good whole organic food affordable to people who don’t necessarily make a lot of money. What follows are just some of the ideas I’ve had.

Building the greenhouse where people are so they don’t have to go very far will reduce ‘food miles’ greatly. By reducing what it costs to get food from seed to table in this way will cut production costs. All people would have to do is walk, bicycle or if needed drive a very short distance to buy fresh food just picked moments earlier. People will also increase their nutritional intake by eating food that was harvested at the peak of ripeness.

Energy is one of the biggest contributors to the cost of food raised in a greenhouse. What if the cost could be greatly reduced or even completely eliminated how would that effect the price of food. By building the greenhouse as a passive solar greenhouse it takes advantage of the solar energy gain during the day storing excess heat underground in a heat battery which can help even out the temperature and reduce the need to heat the greenhouse. Now living in Denver, Colorado there will be times when heating the greenhouse in the winter is needed. In the summer there will be days when cooling will be needed or the greenhouse would overheat. How to handle this?

First, by having more than one method of extracting unnecessary heat and storing it. Heat can be stored under the greenhouse in what people now call a ‘heat battery’ which is a concept that came out of the 70s and has been updated a bit. Using fans excess heat is drawn downward underground and stored. When extra heat is needed the same fans transfer the heat back into the greenhouse. Simple actually. In the 70s a rock bed was used and today pipes laid underground are used instead. The same thing really.

Another way to deal with heating, or cooling needs, is to make use of a heat pump that can efficiently store heat in a large tank of water or use that heat for cooling instead. Either way a heat pump makes the best use of the energy input by returning about twice that in heating or cooling. If there is still excess heat on the very hottest days of the year vents and fans would help move the excess out of the greenhouse.

What if it’s the middle of the winter and there is not enough solar gain, then what? That’s where the passive design of the greenhouse comes into play. It doesn’t just rely on one source of energy to keep the greenhouse warm. To help supplement the need for heating small animals can be utilized, like rabbits. These rabbits can be housed throughout the greenhouse to distribute their heat output more evenly. People who work in the greenhouse would also contribute their body heat. These things would not be able to heat the greenhouse on their own so there has to be something more.

A methane digester could be utilized throughout the year to produce methane that is stored in ordinary LPG or larger tanks. The size of the digester would be determined by the amount of material added each day. A simple digester design used in India which holds about 2,500 liters of material would produce enough gas for a family of four to cook all three meals, heat water or produce light using a gas-lantern for several hours each night. Now this digester is small and meant for a single family, but the potential for producing enough methane is there. In the summer the gas would be compressed and stored and when it gets too cold it could automatically be tapped to keep the greenhouse well above freezing.

Combining the passive solar gain with storage, body heat, heat pump(s), and methane production the cost of heating the greenhouse could be reduced to nothing. Electricity could be produced on site using Photovoltaic panels and windmills. Excess electricity produced can be stored as compressed air in the same way methane is stored and when extra is needed it drives a turbine generator combination.

By reducing the cost of food production makes it that much more affordable. Along with these ideas there would also be the idea of Solidarity Economics. This is not a new concept but one that began in early 1990s which came out of ideas stated in the 1970s. It is all about being fair and less of a consumer driven society that is headed for self destruction.

Not one of these ideas is new. Everything I’ve present has been around for decades. Food shouldn’t need subsidizing it should be freely available to every person at a price they can afford.
