With the onset of farming season, we have been busy at LEF. We expanded our seeds operation by about a third this year. Our seed crops are mostly looking great. The orchards and new berry plantings are also in good shape, though it is an effort to keep them watered. The ducks, the bees, and the humans inhabiting our land all seem to be doing well.
The question of how much food can be grown with organic, sustainable methods is a large one. Each year as we grow bountiful, organic grains and seed crops, we feel more confident that organic farming can feed humanity better than industrial chemical agriculture. Last year we grew Florianni Flint corn. The harvest was fantastic. This year we are growing Kentucky Rainbow, an heirloom dent corn. Industrial agriculture using hybrid GMO seeds is enormously productive under ideal conditions. But under difficult growing conditions, heirloom seeds may actually be better. The old dent corns (like Kentucky Rainbow) are famous for their drought tolerance. Sure enough, we have been having a dry growing season, and we have watched the neighbors’ hybrids shrivel while our Kentucky Rainbow looks like a lush corn jungle. (See photo.) Most of such building energy as we might possess at the end of the farming day has been going into repairing and completing various parts of our main house and surrounding infrastructure in preparation for bringing more visitors onto the land in the coming months. We have had a few leaking pipes and broken solar gizmos that got left behind in the push to make our main house livable. Now we are fixing those issues. If all goes well, we should be ready for doing open-houses and other promotional events in the fall.
We chose woodgas to run our tractors because it seemed like it made the most sense. Woodgas prevented mass starvation in Europe in the 1940s. People have asked us why we don’t use ethanol or biodiesel. The answer is that those are precious fuels that are derived from high-grade feedstock. They compete with humans for food. With woodgas, the fuel is all around us. That being said, both woodgas and turpentine need a warm engine to work well, so a small amount of ethanol would be really useful as a starter fuel. Woodgas is not necessarily easy to work with. Liquid fuels have some big advantages. Now we have a new project. In the next couple years, we will set up a turpentine tractor and see how it works. Kris summed up the situation in a recent email. “I’m thinking what we will need to do for traction in these villages we envision is a variety of fuels, depending on what is available in the particular bioregion. ie, turps [turpentine] in the pine forest, wood gas in hardwood, steam in straw (yes, they made special straw burners for the flat lands), etc. Perhaps combine one or more of these with animal power from time to time.” Couldn’t have said it better myself. (If you are a farmer and you care, the old John Deere models A, B, and D are some of the ones designed to run on “tractor fuel” and are easily hand-started.)
We currently have our wood gasifier on a Power King.
We will build a gasifier for the Tuff-Bilt soon. Our goal is to come up with the simplest, cheapest form of post fossil fuel mechanical power for farmers around the world. We recently discovered Oggun, a new tractor on the market. The primary weakness of small tractors is that they are too light to have much traction. The Oggun puts the engine right over the rear wheels, maximizing traction. The drive train is as simple as it can be, with a hydraulic pump/ motor arrangement as is used on some heavy equipment. (There is a hydraulic motor directly attached to each wheel, which eliminates the need for a heavy mechanical drive train.) The Oggun has a front cultivator attachment point for precise cultivation, as well as an attachment point for rear implements. It’s a great design. Even more amazingly, the intent of the Oggun tractor company is to help other people around the world to make Oggun tractors. Their business plan is quite unique. The intention is to set up distributors who over time become producers, substituting locally (nationally) made parts when possible. Thus the Ethiopian or Brazilian distributors will use steel, engines, and other parts made in Ethiopia and Brazil over time. This, hopefully, will make the cheapest possible (but still functional and effective) tractors for farmers all over the world. See the Business Plan at thinkoggun.com
In the U.S., we have a lot of cheap, used tractors to choose from. In taking LEF around the world, we cannot rely on used equipment. What does the future hold for humanity? Millions of small farmers using Oggun-style tractors running woodgas or turpentine? Walk-behind tractors? Certainly, Kris’s commentsabout diversified motive power sources adapted to local resources are pertinent. The difference at LEF, as compared to the many academic or “demonstration site” ecological research projects is that we rely on our tools to support us — to grow our food, to earn our living. Many ideas that seem fantastic prove impractical in the field. We will do a lot of our farmwork with woodgas this year. In the next couple of years, we will test the practical viability of turpentine and walk-behind tractors powered with woodgas and turpentine. Perhaps we will set up an Oggun with farm-produced fuels. The big question of how we feed ourselves sustainably and equitably on a global scale is a big one. Hopefully we can do our part to answer it. Our work with putting together integrated village energy system using high and low voltage DC power is working really well. We feel like this system is well worth exporting to villages around the world. Hopefully, ongoing improvements to cooking and farm traction will enhance our efforts. Please support us if you can.
