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.

Harness the Sun, Cheaply

7 Replies

The photovoltaic panel isn’t the only hot technology under the sun. The solar cooker, a fuel-free alternative to the traditional stove, is another invention that can harness solar energy. While not as sophisticated as its photovoltaic cousin, the humble solar cooker is an important tool in sustainable development. It heats food by concentrating light onto a black pot using aluminum foil. Unlike a photovoltaic cell, a solar cooker requires neither rare earth metals nor integrated circuits. Its elegant simplicity makes it incredibly cheap to build. In fact, hand-made solar cookers are often made of ordinary junk lying around the house. But don’t let its modest, low-cost practicality fool you: solar cookers can reduce carbon emissions, protect forests, and enrich the poor.

To understand the value of the solar cooker, it’s important to grasp the drawbacks of a conventional stove. Every stove, whether it burns natural gas or firewood, requires fuel. Even an electric stove burns fuel, since electricity from the power grid comes from coal power plants. When fuel is burned, it generates carbon dioxide gas, which aggravates global warming. What’s worse, fuel often doesn’t burn cleanly. Incomplete combustion leads to smoke, which is made of particles that can irritate the lungs and eventually cause disease. The effects are worst for poor people cooking over fires with poor ventilation.

The price of the charcoal in the center is roughly the same price as any of the groups of food around it.

Overuse of cooking fuel leads to scarcity. Burning too much coal and natural gas depletes limited reserves, while burning too much firewood leads to deforestation. Fuel is also expensive, with the heaviest burden falling on the world’s ultra-poor. As much as half of a family’s income may be wasted on firewood alone. That income could have otherwise been invested in nutritious food, clean water, immunizations, and education. The world’s poor don’t have much money to burn.

The solar cooker provides an attractive solution. It runs entirely on clean, renewable solar energy. It produces no carbon emissions, requires no fuel, and saves one hundred percent of operating costs. Unlike with modern stoves, solar cookers can be built with common household items like cardboard, aluminum foil, glue, and a pair of scissors. A do-it-yourself version can be assembled in under an hour.

Solar cookers are based on simple principles. Light rays from the sun are not strong enough by themselves to cook food. Rays collected from a broad region, however, can be focused onto a small pot using reflective metal sheets to increase the delivered power. Pigments on a black pot absorb these light rays effectively to convert them into heat. On a hot day, a solar cooker can reach temperatures up to 165°C (330°F) — hot enough to boil, cook, and bake food.

The CooKit

The two essential components of a solar cooker are the pot and the reflective sheet metal. The ideal pot is black, since dark pigments work best for converting light rays into heat. White pots, or pots with shiny metal surfaces, do not work well because they reflect incoming light. The second component, the reflective sheet metal, is often aluminum foil because foil is cheap and widely available. The foil is glued onto a scaffold (often cardboard, sometimes an umbrella) so that it can help concentrate light rays onto the pot. Variations in design center around the arrangement of aluminum foil and the type of insulation the solar cooker uses.

Two styles of solar cookers are very popular: a box-style solar oven and a panel-style cooker. In a solar oven, the pot is insulated by durable oven walls lined with a reflective aluminum interior. Any heat-resistant scrap material, like bricks or fodder, can be used for insulation. By trapping in heat, a solar oven can maintain a uniform temperature and continue cooking for a few hours after sunset. A panel-style cooker, on the other hand, resembles a traditional stove. It only uses a thin plastic bag for insulation, but it has a large reflective surface that can capture plenty of light. Design plans for both styles are available free online. You can either buy one professionally made, or build one from scratch at no cost. Anyone up for a fun weekend project?

One drawback of the solar cooker is that it heats more slowly than a conventional stove. With a solar cooker, meals take longer to cook and require advance preparation. The CooKit model, for example, requires double the heating time and has a maximum temperature of 120°C. This minor nuisance, however, actually provides unintended benefits. A steady, low-heat simplifies cooking since food cannot burn at 120°C. Once set up, cooking a meal requires no extra stirring or monitoring. There’s also less chance to start a fire.

Alas, there is another caveat: a solar cooker will not work in the dark. Extra insulation can help on overcast days, but don’t expect it to work during a blizzard. Because of this limitation, a solar cooker cannot fully substitute for a conventional stove. On sunny days, however, solar cookers are still the most cost-effective, light-impact cooking technology available.

Solar cookers have much to offer to the world’s poor. Solar Cookers International, the non-profit organization behind the CooKit, has distributed over 30,000 solar cookers in Africa. To help Darfuri women, it donated 10,000 CooKits to a refugee camp in Chad. Not only did these cookers help save fuel expenses, they also allowed women to prepare food without the need to venture outside camp, which reduced their risk of assault while attempting to gather firewood.

An umbrella solar cooker

Solar cookers, however, have been largely ignored in the West. It’s a pity — they are a must-have for the ultralight Greenimalist. They can be built from leftover scrap (cardboard and aluminum) and they use free sunlight as fuel. Panel-style cookers also fold well for easy traveling. What’s more, solar cookers work off-grid, making them useful in campgrounds and homesteads.

One final note: solar cooker operators should wear sunglasses to protect themselves from UV damage. All those concentrating beams aren’t so good for your eyes when you stare at them directly. Then again, wearing a stylish pair of shades might not be such a bad thing, especially if corrugated cardboard and aluminum foil isn’t your idea of green chic.
