The Challenge Begins

Since I started this blog last April, I have been living in the Chicago area describing some of the challenges our society is facing and offering some solutions. But until this point, I have not been able to put into practice very many of my own suggestions. I now have the opportunity to move to a rural environment where I will begin the long journey to self-sufficiency and living a completely sustainable life. I have selected a fertile and watered mountain valley in southern New Mexico as the location of my new homestead. As any journey is easier and more fun with a companion than alone, my mother and I have decided to go into this adventure together. Being a partner in crime who shares my philosophy of life and concerns about the "modern" world, I look forward to sharing this exciting journey with her.

We have yet to even purchase a property, although there is one in particular that we have our eye on. So I have decided to dedicate this blog post towards the decision process we went through in finding an appropriate property for us, what we considered necessary and what are bonus criteria.

Water
Reliable access to clean water is the most important criteria for land selection. In order to lessen the impact if a source of water runs dry, a prospective property should have at least two independent water supplies (as independent as possible, since most water sources are tied to rainfall). And in the terms of both sustainability and self-reliance, do not count any municipal water supply (i.e. piped in water). If it exists, this may be a nice backup while it operates, but should be used sparingly. If it is the only water supply on the land, keep looking. This is important not only because you don't want to rely upon failing infrastructure that is out of your control, but because you also have no control over the energy intensive and possibly environmentally damaging practices in use to pump and deliver that water to your prospective property.

Most sites have one water source that you can count on: rain. Either the current weather patterns of the area provide enough rain for seasonal crops or you can build rain collection devices to store rainwater through the dry periods of the year. If your prospective property lies in an area which receives less than 16" of rain a year, you will need both a shallow water table (less than 100 ft. for a low energy use well) and at least a seasonal source of surface water (spring, stream or river). In addition, you will have to research local water rights laws and determine what water rights are associated with the property deed. The last thing you want is to purchase a property on a river or stream and find out you can't draw even a drop of water from it.

Unfortunately, the world we live in is changing due to the increasing levels of CO2 released into the atmosphere primarily from the burning of fossil fuels. As such any consideration of precipitation as a source of water (or precipitation fed sources such as streams and rivers) would be remiss without at least considering the projections for changing precipitation patterns in the area of your property. The EPA has a good description of regional projections for both temperature and precipitation by the end of the century.

Sunlight
It may seem obvious that plants need sunshine to grow. However, some sites can have less than obvious disadvantages regarding how the sun illuminates the landscape. Look for major obstructions like large trees, existing buildings (especially on adjacent property), hills or mountains or other aspects of topology. Also remember, the sun moves not only on the daily cycle from east to west but also on the yearly cycle of the seasons. For North America the angle of the sun varies from a low of 18 degrees from the horizon at noon at the winter solstice in the north (Grand Forks, ND) to a high of 84 degrees at the summer solstice in the south (Miami, FL). Your property location will greatly affect the seasonal amount of sunlight available to you.

A useful website to help you visualize the movement of the sun for your prospective property is Sun Earth Tools. It will superimpose over a Google maps satellite image of the property the daily path of the sun at any date and indicate the furthest extent at the two solstices. Also keep in mind this evaluation does not reflect the local weather which is obviously correlated to the amount of sunshine available at different times of the year (it is colder in Grand Forks, ND than Miami, FL most times of the year due to the amount of sunlight both areas receive).

Geography
It is also important to notice and take into account the regional and local geography and how it affects weather patterns, rainfall and local heating and cooling cycles. For example, in the northern hemisphere a south facing slope, even in a shallow valley, will have more direct sunlight than the north facing slope opposite and will therefore warm up earlier in the morning, suffer less frost damage in the winter and support more sun loving plants.

Also notice how the local geography affects wind direction which in turn can imply heating and cooling characteristics of surrounding buildings, trees and topography such as a stony hillside. Low lying areas, even of only a few feet, can become cold air traps in winter and are likely places for frost to develop first. Walk the property with a notebook and camera and notice and document all of these details.

Soil
The non-organic components of soil are sand, silt and clay. The definitions of each is based on the particle size not their composition, that of silt being somewhere between sand (the coarsest or largest particles) and clay (the smallest and finest). The current (in situ) relative proportions of these components will determine how much or little work will be required to successfully grow crops on your prospective land. In addition to the amount of organic matter present, the most important aspect of soil composition is the relative quantities of these components. Too much clay and you will have poor soil drainage leading to root rot and other problems. Too much sand and the soil will not hold enough water to prevent the roots from drying out between waterings.

A simple way to determine soil composition is to dig a spadeful of soil from a representative spot (on the surface, don't dig deeper than a foot) and half fill a mason jar with the soil. Fill the rest of the way with water and seal tightly. Shake the jar until the soil is completely dispersed in the water. Set the jar on a level surface for a day or two to allow the soil to settle back to the bottom. The sand will settle out first, then the silt and finally the clay particles (the finest ones). Use a ruler to measure the clear bands of each layer to determine the relative quantities. Easy to manage soil should consist of approximately 20% sand, 20% clay and 60% silt, although up to equal quantities of each is manageable. More sand or clay than silt is an indication that this soil will need much remediation to be useful and you should probably consider other properties.

In addition to these components also look for number and size of stones in the soil (many stones makes it harder to till and weed), how compacted the soil is (did you have to jump on the spade to get a shovelful?) and how many worms or worm holes you noticed in that one spadeful. An absence of worms is always a warning sign and can indicate any number of problems that might be difficult to remediate.

Accessibility
How easy was it to drive to your prospective property? Is it remote? Close to the nearest town? Did you have to cross any dry stream beds (which may flood some times of the year), steep hillsides (may ice up during the winter) or other terrain features which may make access difficult during the various seasons? It may be worth while to visit at night to notice how easy it is to find the driveway or negotiate the nearby roads. How easy will it be for someone else to find the property? You most likely will take a delivery of a package or possibly large shipment at some point. Will this be an issue or inconvenience? This is particularly important if you plan on any large construction projects like building a new home, barn or other structures on the property.

Vision
Can you see yourself living there? This sometimes can get lost in the shuffle with viewing multiple properties and checking off the list everything mentioned above. But don't forget why you are buying this property. Notice the neighborhood and surrounding properties. Are they well kept or run down? Are there others in the area homesteading or growing kitchen gardens? Is there a local community of like-minded individuals or will you be forging a new path in this area?

Try visiting just before sunset, setting up a lawn chair and simply sitting to watch the sun set. Notice the noises, traffic, people or whatever else goes on around the property. Is this a view you can live with? What don't you like about it? How does that balance out with all the positive qualities of the property?

Good Enough
Finally, no property is going to meet all of your needs. The real challenge is to decide what is truly important to you and make sure you are selecting the property that is good enough to meet those needs without waiting for that perfect property that may never materialize.

The Problem with Fusion

Although there are many technical challenges that still remain in order to make fusion energy a viable source of electrical power generation, the main reason humans will never harness fusion energy is one of economics. By the very nature of a fusion reaction, pressures and temperatures only experienced within stars, fusion reactors are necessarily the most complex and technologically sophisticated machines built by man (the Large Hadron Collider (LHC) at CERN is another candidate). As such, fusion reactors are also among the most expensive. No amount of technologic breakthrough will make fusion generation a cheap enterprise. In order to recoup that expense, massive economies of scale have to be achieved in order to make fusion energy a viable source of electrical power generation. But massive economies of scale can only be achieved with massive installations which bring about a whole host of other problems like local environmental impact, vulnerability to local weather and geologic phenomenon (earthquakes, tsunami, etc.) not to mention human caused events such as accidents, sabotage and military action. Finally, massive installations have huge price tags.

First let’s look at the order of magnitude kind of cost we can expect. Nuclear fission technology is about 80 years old and by all standards a fairly mature technology, even considering the latest reactor designs like advanced boiling water reactors (ABWR). The largest nuclear power plant in the world is Japan’s Kashiwazaki–Kariwa NPP which as seven reactors for a total generating capacity of 8 GW (8,000 MW). From ground breaking to first power generation took more than four years. The last reactor did not come online until 12 years after the first one requiring huge capital outlays before revenue could be collected by selling the generated power. The average cost per kW of electricity generated is about $5,000 or a total of $40 billion to build the entire complex.

Here is a list for cost comparison to other relevantly complex machines:

• Trident nuclear missile submarine – $3 billion
• Nimitz class nuclear powered aircraft carrier – $6.2 billion
• Lifetime cost of Space Shuttle program – $200 billion ($1.5 billion / flight)

The International Thermonuclear Experimental Reactor (ITER), the only commercial fusion reactor program currently funded has an estimated price of $18 billion. (The US National Ignition Facility, the only fusion project in the US, is changing priorities after failing to meet the goal of "ignition" when the latest round of funding ended this last September.) It’s designed net power generation is 450 MW. This is only 5% of the power generated by Kashiwazaki–Kariwa NPP for almost half the cost. So even assuming ITER is a complete success, which is doubtful considering the immature state of the technology, it will not be economically viable. But it is a demonstration of the technology, so economics are not the primary objective.
However, the outlook for fusion gets worse. The economies of scale required for a large fusion reactor demand generation on the order of 5 – 10 GW. This falls out of a complex analysis of cost for power generation that ranges from $2000 / kW for state-of-the art pulverized coal plants to $10,000 / kW for the latest ABWR nuclear fission power plants. In order to be economically viable, a fusion power plant has to deliver power within this price band. For maximum economies of scale, at $10,000 / kW for a total of 10 GW power generation, this equates to a total lifetime cost (capital, operating, fuel and financing) of less than $100 billion. For a 20 year lifetime, this would approximate to $80 billion to build and $1 billion annual costs. And this would make the electricity one of the most expensive sources. To come down to the $2000 / kW of coal fired plants, the build cost would have to come down to about $16 billion. That’s already less than the projected ITER cost for only 450 MW of generation.

There are few aspects of the technology required to fuse hydrogen atoms that indicate orders of magnitude cost reduction over time. Compare the costs of the largest partical colliders as they have grown in size over the last 20 years. The closest parallel technology on the electric power generation front is the evolution of nuclear fission power plants. Even at the enormous economies of scale afforded by Kashiwazaki–Kariwa NPP its cost per kW is still in the middle of the cost band for electrical generation sources. Most of the worlds nuclear power plants fall in the upper reaches of this price band. So even under the very best of technological circumstances, fusion power will never be a viable source of electrical power generation purely for economic reasons.

In the name of Progress?

I live in a suburb of Chicago far enough away from the city that there are still a few farms that have yet to be paved over, an abundance of green spaces, stretches of forest and a fairly unspoiled, picturesque river valley. Recently, in the name of progress, the city purchased several developed pieces of land, one containing an abandoned warehouse which was burned to the ground by vandals, in order to build a road bypass to improve traffic on a congested major artery. The only problem is about ten acres of land smack in the middle of the developed parcels that is covered in forest, is bordered by a popular bike path on one side, one of the oldest parks in the city on the other and split by a winding stream that feeds the nearby river.

This is a problem because in order to complete the bypass, every last tree, bush and blade of grass on the ten acres will have to be "removed" and several small hills up to twenty feet high will have to be leveled. I think most commuters stuck in the daily traffic jams on this major artery are willing to sacrifice a few trees to improve their commute time. For them and the city planners who approved this project I would like to offer a perspective on what we are giving up for our commuting convenience.

I ride my bike on the bike path passed this piece of land on a regular basis. During the hot summer months I appreciate the shade from the trees that provide a soft canopy dappled in sunlight, the cool breezes that filter down the hillside and the sight of any number of animals from deer to raccoons to hawks to squirrels and opossums, not to mention the dozens of song birds who make their home in this little patch of forest.

The bike path is built on an old railway line and there is a 100 year old stone bridge crossing the little creek in the woods. I stop occasionally to marvel at the large limestone blocks chipped out of a nearby quarry by men who have been dead longer than I have been alive. There is a dirt path that leads down from the height of the bridge to the stream bank and follows it through the wood until it emerges out into the park. I walked this path once and was amazed how after only a few twists and turns I felt like I was deep in a forest far from modern life. Although only a few hundred yards from the bike path, I could sit on a log by the stream bank, listen to the bird calls, the water gurgling over the round stones and at least pretend I was deep in the wilderness.

Yesterday I walked down the bike path knowing that my forest was gone. The bulldozers and road graders were parked on the black earth like giant, yellow insects waiting to devour their next meal. The bile rose in my throat as I walked closer. I was having a hard time recognizing where I was since all my familiar landmarks had been obliterated. The landscape reminded me of battlefield films and pictures. The trees had all been cut inches from the soil, their limbs and trunks gone, already hauled away. The churned up soil was littered with shredded plant debris, tree limbs broken into fibers as if separated by a bomb blast. I couldn't help but think of all the animals. I picture a moment like in the movie Avatar when the giant machines tear through the forest devastating everything in their path and the animals all running in the opposite direction to avoid annihilation.

 

But I want to get beyond the Bambi moment of denouncing the hunters who shoot his mother. The perspective I want all of us to consider is with what are we replacing these natural habits that we destroy in the name of progress? Steel and concrete? A sterile sheet of sod laid on top of a bulldozer sculpted landscape? The incredibly diverse forest ecosystem with all its plants and animals is lost. In this case it is only ten acres, but it is a microcosm of what we are doing all over the country, all over the world. We need to remember that we live in the natural systems around us, not outside of them. The more harm we continue to inflict on these systems, the more harm we ultimately are inflicting upon ourselves.
