CD3WD: Do Everything Yourself

Learn how to fish, eat for a lifetime. Browse CD3WD, stop shopping forever?

We all know the proverb of teaching a man how to fish; the challenge is in getting us to practice it. Self-reliance, according to the saying, is far more useful than continual outside aid. Yet each year, droves of consumers still choose to abandon small-scale, local production in favor of high-tech factories run by international corporations. Over time, many local communities have lost their local artisans, and with them the means for self-sufficient production. Without the butcher, baker, and candle-stick maker to pass on their traditional knowledge, practical skills are quickly forgotten. Eventually, basic life necessities must come entirely from imports thousands of miles away.

More than nostalgia is at stake here. Keeping production local is the key to a sustainable culture, since local producers can better use appropriate technology suited for the environment and local economy. Compared to centralized factories, local producers burn less fuel, use less chemicals, and profit more from the long-term health of the land. Small-scale producers can better substitute unsustainable machinery with human labor and local know-how, and they help communities avoid depending on distant, unreliable supply chains for basic survival.

One way you can bring self-sufficiency back to your local community is by learning to do things yourself instead of shopping. By doing things yourself, you can bypass our dysfunctional consumer culture while saving money, learning practical skills, and having fun. The possibilities are endless: you can learn to sew clothes, make fruit preserves, fix bikes, build furniture, repair old electronics, start a vegetable garden, and even build a solar thermal heater. In fact, there has probably never been a better time for the do-it-yourself hobbyist. Anyone with an internet connection today is a mere hyperlink away from the largest collection of self-sufficiency books ever compiled.

Read books on how to make your own chairs, tables, cabinets, and drawers.

For over a decade, software engineer Alex Weir has been hosting CD3WD, a massive digital library with the mission of helping the poor learn to do everything themselves. CD3WD contains over 10,000 e-books (14GB of digital data) of high-quality, public-domain material stored on CDs (now DVDs) for distribution to the third world. Nearly every aspect of self-sufficient living—from vegetable gardening to assembling a low-tech washing machine to building adobe houses—is covered in this massive compilation. For the third world, CD3WD currently offers free DVDs of the entire digital library. For the rest of us, the compilation can be downloaded from the website at no-cost, or DVD copies can be purchased for a nominal price of $20. It’s a bargain when you consider its amazing value. Aside from the Bible, this may be the most useful collection of books in the history of mankind.

It’s difficult, however, to discern this on your first visit. CD3WD is very humble about the way it presents itself. Visitors will at first notice the complete lack of attention paid to visual aesthetics: the retro-style HTML design, mismatching color scheme, and chaotic organization of books doesn’t inspire much confidence. CD3WD also describes itself as a set of books for the poor, which creates a subconscious stigma for those of us reading in richer nations. So as you browse the site, just keep in mind that CD3WD is truly a diamond in the rough.

From another angle, however, the humble nature of CD3WD is its greatest strength. Because this project is geared towards helping the poor, it has a very pragmatic focus. The collection strives to include only practical, technical books with limited fluff. Its books are written with depth, and yet, simultaneously, are written in simple English for accessibility. Unlike typical DIY books, CD3WD focuses on sustainable development through appropriate technology. These books use techniques that are cheap, reliable, and simple to set up. Since the poor often don’t have access to electricity, gasoline, or industrial chemicals, these books recommend locally-available resources instead.

There are do-it-yourself projects inside this collection to match everyone’s interests. For those who can’t garden, consider checking out manuals on woodworking, home construction, and making clothing. Other interesting books cover preserving food, blacksmithing, and building composting toilets. Suburbanites who bicycle commute can benefit tremendously from the bicycle repair books; fellow homesteaders should check out those gardening books published by VITA (Volunteers in Technical Assistance) and BF (Better Farming).

Fix up your old bicycle for commuting to work.

More than anything else, this compilation is worth checking out because it teaches us that we can survive without shopping. It is a refreshing message in a consumer culture where all life’s needs are currently satisfied by malls and chain stores. There is joy in discovering that modern people can indeed be self-sufficient, even if they can’t practice it all right away. Gradually, these books might encourage us to be self-sufficient in ways we had never thought possible before. Perhaps then we can get one step farther away from buying fish fillets and one step closer to actually fishing.

Update (10/12/2011): CD3WD is a great project overall; however, it has come to my attention that the huge CD3WD library may include a tiny amount of material on family planning. Often, this involves the practice of abortion, which the Bible teaches is murder. Please enjoy CD3WD’s library, but don’t support or practice abortion in any form.

My Move to the Country

Planting a Squash Seedling

When I first started Greenimalist, I began with lifestyle changes that were compatible with life in the modern city. On one hand, I am amazed at how far I have come towards lowering my impact while living in the city. At the same time, however, I have always felt stifled by life in the urban jungle. Without land of my own, I could never take Greenimalist to the next level. In a small apartment, it can be a challenge to make compost, start a vegetable garden, or even test out a solar oven (we didn’t have a sunny patio for the cooker to sit on). Hsinya and I have wanted to raise poultry for several months now, but we have always hesitated to raise them indoors. A lack of space, combined with uncooperative neighbors and landlords, has made it difficult to experiment with Greenimalist living. For this reason, I had been planning to buy land of my own someday. In the meantime, however, I had little recourse but to watch other homesteaders with envy.

All this changed last week when my aunt offered me a chance to start a garden in her vacant country-house. Located in a rural farming town, this unoccupied house has a backyard over half an acre in size — plenty of undeveloped land for experiments in self-sufficiency. I was essentially given free reign to experiment with any project related to homesteading, such as organic gardening, setting up off-grid solar panels, collecting rainwater in barrels, and composting chicken poop. I could hardly contain my excitement.

Hauling Compost to the Garden

I had very few expectations for the house itself. In fact, I was fully expecting to live in a low-tech, off-grid primitive shelter, more resembling a log cabin than a house. In a strange way, the idea of roughing it in the countryside seemed almost enjoyable. To my surprise, the country house was modern and luxurious for a homestead — it had electricity, refrigeration, natural gas, and indoor plumbing. I could, in fact, sign up for broadband Internet at any time — so much for roughing it. After a quick reflection, however, I concluded this was probably better anyhow. I should be concentrating my efforts on gardening for now, not on how to build an off-grid shelter.

The backyard also far exceeded my expectations. There was plenty of fertile land for subsistence farming. Having never been sprayed with pesticides, the soil was teeming with a healthy ecosystem of insects and microbial life. (In fact, some pests from this ecosystem ate my pumpkin seedlings last night.) Trees dotted the backyard, and underneath the leaf litter, there were rich layers of humus perfect for gardening. The land was definitely excellent for gardening.

Without hesitation, I knew I wanted to stay. Sure, there were minor flaws — hordes of virulent mosquitoes, the lingering smell of cow manure — but I couldn’t pass up the offer. That very night, I packed all my minimalist possessions, took the bus to the countryside, picked up the house keys, and became the new tenant.

This is a big step forward for me in my journey towards a more sustainable and natural lifestyle. As always, Greenimalist will still be about simple, green living: shopping less, owning fewer possessions, conserving natural resources, and protecting the environment. Since many of us will continue to live in the city or suburbs, I’ll definitely keep writing tips for green living in the cities. However, I’m excited about the latest saga of my Greenimalist adventure: low-impact self-sufficiency on a country homestead.

Why I Want to Homestead

Homesteading is the most ecologically-sound lifestyle possible. Unlike the modern, consumer lifestyle, homesteading is gentle on the land, good for your health, low on stress, and very cheap. It does require plenty of patience and hard work, but that’s a small price for sustainability, independence, and a healthier way of living.

A More Wholesome Life

Healthy food is difficult to find nowadays. Most supermarkets are filled with junky, processed food. Even the fresh food section is contaminated with the poisonous pesticides used by conventional farms. These toxins harm the earth, the farmer, and your health. Only unprocessed, organic food is truly wholesome. Growing my own food is one way to ensure that I will have plenty of fresh and nutritious food year-round, even in towns that don’t sell organic food.

Ultimately, I want my home to be the nucleus of a sustainable family life. A good homestead provides a retreat from all the unhealthy stressors of modernity. It’s a place to get away from traffic, smog, cigarette smoking, pesticides, and synthetic food. When we have kids, we want them to have a wholesome childhood — free from potato chips and video games.

Financial Independence

By homesteading, I also plan to save money. Not only does growing my own food help save thousands of dollars each year, but a house in the woods represents a huge savings compared to a house in the suburbs or city. Undeveloped rural land is much cheaper than urban land; I can buy acres of land for just a few thousand dollars. If I learn how to build my own house, I can also save on housing construction costs. My goal is to continue working online while ruthlessly cutting expenses to build up savings.

My Goals

I don’t expect to be totally self-sufficient this year. Instead, I plan to use this opportunity as more of a learning experience. This country house will be a sandbox for self-sufficiency experiments, including organic farming, permaculture, country living skills, and alternative energy.

Our first goal is to produce all of our own vegetables by the end of this year. I’ll also experiment with growing quickly maturing fruits like melons and strawberries, as well as rice and beans by the end of the year.

Our second goal is related to the first: we will try to process all the food we eat on the homestead. Hsinya will make everything we eat (e.g. soymilk, cheese, bread, and soy sauce) right on the country house. We experimented with some of these ideas before, but having more space allows us to process on a larger scale.

Our Homesteading Principles

Organic Gardening

Obviously, we’re not going to be using toxic pesticides and chemical fertilizers on our homestead. Not only do these poisons harm the soil, they also poison the farmers that use them. Organic agriculture, however, means much more than just abstaining from chemicals. Growing food organically is also about cultivating a richer ecosystem for the farm through building fertile soil.

As I homestead, I hope to strengthen the ecosystem in our backyard. Unlike modern farms, which destroy the soil over time with chemicals, I’m hoping to actually increase the amount of topsoil over time. I plan to compost kitchen scraps, mulch the soil, practice companion planting, sow cover crops, plant fruit and fodder trees, and encourage beneficial insects. Farming organically is like buying carbon offsets, only better: instead of paying someone to plant a tree for me, I’ll plant my own apple tree and harvest the literal fruits of my labor. It actually pays financially to make a positive impact on the environment, because it improves the fertility of each year’s harvest.

Self-Sufficiency

I will try to avoid shopping — not even for farming supplies. Whenever possible, I want to live off the land and be totally self-sufficient. My main motivation is to save money: it’s expensive to rent rotary tillers, import compost, and buy lumber. Many aspiring homesteaders fail because they waste too much money buying expensive farm mansions loaded with fancy appliances and equipment. Such a facade is not true self-sufficiency; even worse, it is outrageously expensive.

Appropriate Technology

Whenever possible, I will opt for low-tech, simple tools on my homestead. So far, all my gardening tools require human labor rather than gasoline or electricity. It may be tempting to use high-tech machines for homesteading, but there are often cheaper, more sustainable solutions. When I lived in the city, for example, I discovered that bicycling was more cost-effective than driving. This homestead will give more opportunities to explore appropriate technology for self-sufficient living.

We’ll keep you updated on our homesteading as we learn from our mistakes. I hope these articles help provide a candid look at one ordinary couple’s journey towards self-sufficiency. Until then, our homestead awaits.

Human Power: That Other Renewable

7 Replies

Bike-powered peanut sheller and blender

Of all the renewable energy sources available today, one of them is constantly overlooked by modern society. It’s a shame, because this renewable energy is easy to harness, uses little space, and is complementary to wind and solar energy. I am speaking about that other, forgotten renewable: human power.

Using machines like a hand-crank, treadle, or pedal, human labor can be harnessed as mechanical or electrical work. The most common human-powered machine is the bicycle: mechanical work from a pedal is used to turn a wheel, which propels the rider forward. Bicycles, however, are not the only possible human-powered machines. With some clever engineering, human power has been harnessed to crank washing machines, plow fields, and saw wood. A bicycle can even generate electricity if equipped with a generator, voltage regulator, and battery. It can then power light bulbs, flashlights, laptops, and vacuum cleaners.

Unlike other renewable energy sources, human power requires active labor. Modern society, with its distaste for exercise in general, rejected human-powered machines for this very reason. That’s a shame, because human-power provides a nice complement to solar technology. Pedal-power can provide a handy back-up to photovoltaic panels on cloudy days. What’s more, pedal power can create short bursts of electricity, in contrast to the steady-stream of low power provided by solar panels.

An illustration involving an LCD monitor can provide perspective. A typical monitor requires around 100W of power to operate. After cloud cover and the earth’s tilt are considered, a photovoltaic panel might produce a power of around 25W/m^2 on average (1). So to power the monitor, we would need 4m^2 of solar panels. It only takes a single stationary bicycle, however, to generate 100W. Space is only needed for the bicycle itself and a few electronics, so the whole system can be contained in around one square meter. A fit cyclist, moreover, can produce even higher rates of sustained power — up to 200W in athletes. As a result, a well-trained cyclist can produce twice the energy of a photovoltaic panel in one-fourth of the space.

Pedal-power is not unreasonably expensive. A stationary unicycle can be built for under $250, and accompanying electronics can be purchased for around $400 (2). The combined total is $650, roughly the cost of similar solar panel installations.

The real cost savings, however, are for appliances that require only mechanical power. When there is no need to purchase expensive electronics, pedal power is clearly cheaper, since these machines can be built using only donated bicycles, spare hardware, and elbow grease. One NGO based in Guatemala, Maya Pedal, has taken discarded bikes and retrofitted them to make useful tools for local farmers. Old bicycles have been used to blend soap, pump water, grind flour, shell peanuts, and thresh grain. Not only has this removed the drudgery of agricultural work, it has also increased the income of local families. These projects promote development without burning extra gasoline or coal, all while recycling old garbage.

The Western world could learn a lesson. We chronically suffer from energy shortages, and we have no lack of people needing exercise. In the United States, more than one in four Americans are obese, and six in ten overweight. Cheap energy has allowed us to live sedentary lifestyles, which shorten our lifespans and waste trillions of dollars on unnecessary healthcare. If couch potatoes were forced to pedal for their television time, the rates of Western diseases — heart attacks, strokes, diabetes, and cancers — would rapidly plummet.

This is much better than going to the gym. Not only does gym membership cost thousands of dollars, but workout machines like treadmills actually waste additional energy to power. The average treadmill consumes 1500W of power — enough power to run 20 laptops. When people drive to the gym, moreover, they further add to greenhouse gas emissions. With human-power, they could instead burn their extra fat for productive purposes. Those calories might as well be used to wash clothes, blend smoothies, and generate electricity. Why not combat global warming while getting in shape?

Pedal-powered washing machine

Whether human power can truly make a difference depends on the efficiency of the exercise machine and the power demanded by your household. The average person can produce around 35-60W of power using a hand-crank, and 100W-120W using pedal power. Cell phones, flashlights, and watches can all be powered by hand-crank, while computers and televisions can be powered by pedals.

This sounds promising — that is, until you consider our monstrous demand for power. A medium-sized, window air conditioner uses around 1000W of power. To supply the energy for just that one AC unit, it would take a team of ten cyclists pedaling at full speed for the entire day. Once you add in laptops, televisions, clothes driers, washing machines, heaters, and light bulbs, human power becomes woefully inadequate. It would take a legion of cyclists to support the typical American home.

Storing generated electricity is a problem as well. Most pedal generators use lead-acid batteries, which store energy for later use. Devices can then be plugged into the battery rather than directly to the exercise machine. This helps avoid the awkward situation of having to simultaneously pedal while using your laptop. But as Low Tech Magazine points out, lead-acid batteries require massive amounts of energy to manufacture. Sulfuric acid can also cause severe burns, and lead can cause birth defects and brain disorders. Even pedal-powered electricity, then, isn’t perfectly green.

This limitation can be largely overcome by simply transmitting work mechanically rather than electrically. One clever hobbyist retrofitted his bicycle to spin washing machines using only pulleys and belts. The Human Powered Home, a compendium of do-it-yourself pedal-powered machines, provides plans for mechanically connect your bicycle to a grain mill, sewing machine, and tool sharpener. With a little ingenuity, the mechanical applications of pedal power are endless.

Despite its flaws, human-powered electricity can still contribute to sustainable living. Every renewable technology has its limitations, and a human-powered generator is no exception. They may not be perfectly green, but neither are solar panels. When used properly, the benefits of renewable, off-grid electricity can outweigh the harm caused by pedal-power electronics.

Generating your own electricity can allow you to live off the land, which dramatically reduces your carbon emissions. One difficulty with living on rural, undeveloped land is the lack of grid electricity. Pedal power, along with photovoltaic panels, can provide electricity without an expensive connection to the utility company. One Laptop Per Child, for instance, has taken advantage of human power to design off-grid laptops. Students in remote villages often lack access to electricity, but one minute on a hand-crank can provide enough energy for ten minutes of laptop use.

Yet the most profound impact of human power is not the generated electricity itself, but rather the conservation ethic it instills. Producing electricity is hard work. When we hook up an appliance to a power outlet, we are blind as to how much energy we are truly wasting. But if we had to pedal forty-five minutes for each hour of television we watched, we would be more conscious about our electricity usage. We would never have to be reminded to turn off our lights or to sleep our computers, and few would dream of using an air conditioner. Ultimately, it’s conservation — in addition to our feet — that will provide us with the power to lower our carbon footprint.

Do-it-yourself bicycle-power plans are the most affordable and have the lowest environmental impact. There are also some commercially-available attachments. They are expensive, however, and may actually waste more energy than they produce. I encourage you to build your own instead.

Sustainability: Energy: Without the Hot Air generously estimates that a solar panel in Britain produces around 22W/m^2 on average. Low-Tech Magazine estimates a power capacity of 100-150W for average cyclists and up to 300W for athletes.
The Pedal Powered Prime Mover is one unicycle designed especially for pedal power. It costs around $100-$250. The exact electronics will vary depending on your needs.
