Open Source Technology


The open source backhoe is complete. Check out the finished product as attached on our open source tractor:

Field testing showed some explosive news. See for yourself:

I ran over to Sweiger Shop right after, to get a larger shaft. The store was closed – I forgot it was Saturday. On the way back, I stopped and picked a bushel of juicy Jonathan apples from a neighbor. After downing four of them in delight, I said to myself – “hey, wait a minute, why don’t I just fix the tractor myself?” After all, I designed it for absolute simplicity and replaceability of parts. A redesign of the shaft coupling – and I’ll be up in no time. Yes, that’s what I’m doing today, and I should be up digging with the new toothbar bucket by noon.

The backhoe itself was not so effective the front of the tractor comes right off the ground as the bucket takes a bite in the hard clay. I need some weights on the front for backhoe work – probably another 1000 pounds.

Because LifeTrac has difficulty digging clayey soil for CEB bricks – we added breakthrough teeth. Pun intended.

LifeTrac is a toothless granddaddy no more. Now the digging bucket will munch the ground up like cotton candy.

Field testing is forthcoming. You can contribute content to the open source tooth bar wiki page.
I had a personal breakthrough, too – regarding Open Source Ecology. (more…)

Building on the work in the last post – if one simply puts a shroud around the Babington burner flame to retain the heat – the flame becomes self sustaining. Preheated to 140 F, the oil lights immediately and continues to burn:

It’s getting cold here – 40 F last night. We’re scrambling to press bricks, and hopefully we will have warm space soon with the Babington/wood CEB masonry stove.

The spirits run high as Bob’s Bab Lab produces a roaring Babington burner flame at Factor e Farm:

Our next steps are to put a shroud around the flame for flame continuity, and installing a water heat exchange coil in the shroud for hydronic heating, steam generation, and other applications. We are currently considering a CEB masonry stove – the CEB kachelofen – as a center of our CEB additions. We would like to use this stove for hydronic heating, cooking, drying, and soon as a steam source for combined heat and power.Any details on winding techniques for continuous steel tubing are welcome. We are considering a 100 foot coil of 1/2″ or 3/4″ heat exchange coil – which we are trying to wind in a 6 inch spiral. Also, details on a possible masonry stove design are welcome.

Today we started to put together our Babington burner. This burner is important because it is a versatile source of heat for: space heating, metal melting, glassworks, pottery, steam engines for remote power, heat engines for mobile power in cars and tractors, and many others. We can use it with any waste oil – crankcase, vegetable, etc. – plus pyrolysis oil from biomass once we develop it. It is not a far stretch to produce pyrolysis oil- see this simple experimental proposition. Do you think this would yield useful amounts of liquid fuel?

For the Babington burner, we drilled a 0.0135 inch hole in the face of a hollow, brass doorknob – and brazed on a fitting that supplied compressed air at a constant pressure between 20-35 psi. We were able to atomize water but when we tried motor oil we had problems. We were able to produce a bit of a flame but never sustained burning. Two possibilities: 1) the hole became clogged from debris inside the burner ball, 2) the oil was not heated sufficiently. Has anyone had success in sustaining a flame over a long period? What is a good method for automatic ignition? Best way to regulate the flow over the ball? Any feedback is welcome from experienced Babsmen.

Here is video documentation for making the first two parabolic reflectors for the Solar Turbine project:

The Solar Turbine Convergence is here – Elliot and I are continuing on the next reflector version, and we are picking up Stuart today.

We’d like to note that we ran into a serious snag with using 4′ wide parabolic receivers in an east-west array of reflectors – which is our latest implementation concept. Daily solar motion changes the distance of the solar path to the receiver – such that at best, it appears we can get 2x concentration from parabolic dishes – such that the image size at 9 am or 3 pm will be half the reflector width – or 2 feet here. If you are familiar with this dilemma – helps us – and consider joining the Solar Turbine group. It looks at present that we’ll be returning to 1 foot wide slats instead of these 4 footers. We are going through one design issue after another – which is good. We’ll see how far we’ll get by the end of the Convergence on Sep. 3. We are presently aiming at about 50x concentration.

In part one of “Digging for Water”, we drilled a hole 85 feet deep, hit water, and tried to insert a 6 inch casing (pvc pipe) into the hole. When the 6 inch pipe didn’t fit, we decided to use a 4 inch casing. Although the 4 inch casing dropped much deeper than the 6 inch one, to our chagrin, it wouldn’t extend the full depth of our hard-earned hole.

With a little trial and lots of error, we eventually submerged the 4 inch casing 25 feet into the ground. Fortunately for us, we could see water trickling into the hole, not more than 10 feet below the surface. All in all, we now have a supply of 1000 gallons per day.

So, now the ground water was sitting in the hole, but how do we get it out? The fit was too tight for our 4 inch diameter submersible pump. And we couldn’t easily find a smaller size. In desperation, we turned to a hand pump. Everyone used to have hand pumps, why couldn’t we. It’s a good tool for learning to appreciate water after all.

This short clip is of our adventures in learning how to get water out of a well. Mainly, making a cylinder, a $50 project with open source plans from Hydromissions (which would have cost us several hundred dollars otherwise) and attaching the hand pump.

So, grab a glass of water, sit back, and enjoy another episode of Factor E Live!

The last two weeks were primarily spent on the well, which is now (almost) finished. So, our biweekly video focuses on our voyage into the earth, in a search for ground water. We begin with a homebrew rig that is difficult to use because we cannot easily raise and lower it. We end with an 85 foot hole, that is reduced to 25 feet through weak equipment (resulting in a crooked hole) and some mistakes (like pumping out silt without any casing, causing sand to fill-in the hole).

This is not a “how to” video, but more a taste of what it would have been like to help us dig our well. We plan to more fully document our experiences here and on the wiki once we’re truly pumping water from the well.

Enjoy!

We have finally completed our water well-drilling adventure. Everything that could went wrong – amounting to a 2 month delay – but the bottom line is that we have a 4 inch-bore well that we estimate is giving us 1000 gallons of water per day based on the pumping that we have done so far. We have yet to see whether the well dries up in late summer heat. See our second Factor e Live video (forthcoming by tomorrow) for more documentation on the well.

This means that we are at a great transition at Factor e. The next step is full time work on LifeTrac – and we aim to have it driving in 2 weeks and fully operational with loader, rototiller, and other implements, in 1 month. Our primary attention will go to this – as it is the backbone of the infrastructure for CEB construction – to start on July 15. That’s when the great promise of quality, dirt-cheap building will be tested in practice – as the first example of high-caliber, appropriate technology equipment developed at Factor e Farm. We will then be able to tell if our CEB machine, The Liberator, is worthy of its name.

The next point to mention is the solar turbine- we’re planning ground-breaking on August 15. Our design specification is an affordable, kilowatt-scale, scalable, solar concentrator electric system based on a linear (scalable) reflector Fresnel design of 16-fold solar concentration:

(source). Based on proven techniques, we are predicting exciting results. The bottom line prediction – using overall 8% efficiency (nothing spectacular) from solar input to electric power – is 3 kW of electricity from a 4×10 foot array of mirrors. If we succeed at this, then we will have a breakthrough in solar power generation. What I mean is that none of the ideas utilized are in any way original – but we are putting them together from the systems design perspective – and resulting costs are 2-10 times lower than any system that we are aware of, at any scale of operation. Our calculations show a materials cost of $2000 for the reflectors and collector – plus another $500-$7000 for the turbine, generator, and balance of system. We are talking of costs for solar electricity at 80 cents – $1.30 per installed watt. This is cheaper than coal power plants. Add the labor costs on top of that if you are doing this for outside markets – and we may be talking of replicable power systems that bring about the promise of solar economies.

The trouble is, we’ve heard predictions of cheap solar for many years – but solar cells are still at $5/watt and $10+ for installed costs – and no better alternatives are emerging, except at large scales. How are we any different? We’ll see – but we do have open source methods working for us here. Please continue reading below about our quest for the world’s first replicable, open source solar turbine package. Here we discuss heat engine choices – the universal missing link in such projects.

It has taken me a while to allow my experiences and inspirations from this weekend at Factor E to gestate, to ferment into tangible thoughts that I can easily disseminate to readers. Being lucky enough to sit down with Brittany and Marcin and talk face to face about what people are dealing with in this world, what we can do, and putting plans into action that can move to empower us all to have more control over our lives, has been a remarkably rewarding experience. We jokingly talked about the concept of “sitting-on-ass” (a reference to the movie Idiocracy), and how helpless many of us tend to feel, sitting around on our computers using grid power, posting blogs about how we can change the world as we often actively and knowingly perpetuate the status quo to our own guilt and disdain. My fellow sustainability junkies and myself know this feeling all too well, yet getting off the grid, if only for days at a time, and more importantly living among those who live for Global Swadeshi is more than enough to convince me that what you and I work for is possible and that we really can do something about it.

So, before I get so much into what we talked about over the weekend, I’ll fill everyone in on what it was like to experience daily life on Factor E. I got in late at night, and thanks to the generosity of Mrs. Crowther was able to be guided to the farm (it’s a bit off the map, get directions when you go!). And just in the first night I was overwhelmed by what a different world I had been catapulted into: reading Ishmael (Daniel Quinn) by a compact flourescent bulb run on off-grid power, in a cordwood house, replenishing my thirst with barrel collected rainwater (the well is nearly done for the wary), and immediately I was engulfed with an abundance of generosity and hospitality by the folks there. Outside I smelled the fresh, cool night air, free of the stench of exhaust fumes and the noise of the city.


The next morning I awoke to the sound of roosters crowing and chicks tittering and goats braying (is that what its called?) and Brittany letting the ducks out of their nest. I enthusiastically took to the garden with her, pulling unwanted plants (notice how I didn’t call them “weeds”, more about wild plants later), and feeling much better than when I do the same at my landscaping job, where I work in sterile, chemicalized, “aesthetic” beds. From the garden, while I was there, we ate broccoli, green onions and perennial onions, garlic, and various other foods.

Brittany and I, the next day, would find ourselves going out to the reservoir (in biking distance!) and encountering an abundance of wild fruit… among the wild grape vines and flowering blackberry brambles, the wild strawberries were delicious and ripe for the picking (we would eventually make some yummy jam thats been a hit back here in Columbia).

While out there we discussed the concept (and reality) of wild food forests, and how many wild plants on the Panamerican continent there are that have been selected for over thousands and thousands of years by indigenous peoples, carefully and with a profound knowledge of the ecosystems and bioregion so nuanced that it would probably escape some plant biologists. This knowledge of wild plant propagation and food forest management had been passed down through multitudes of generations through folklore and through experience in the field. They had encouraged these plants to be self managed, adaptive, resilient and fruitful, and in such a manner as to prevent invasiveness. And, as she pointed out, on a higher level, these humans were entrenched in the environment, such that even the animals around them were selecting for these plants as well, and these plants evolved to spread their seeds through multitudinous means. The implications of this kind of resource management are huge and point to some of the fundamental underlying principles of permaculture. The potential for ecological sensibility, sustainability, and abundance is obvious. Not to dis more euro-traditional sustainable agriculturalists who use less biomimicry, and more row cropping techniques (though i suggest intercropping, agroforestry and wise encouragement of wild influence), as these techniques seem to work well enough. However, time will tell which techniques work better in different situations and for different uses, though I’ve got my wild berries bet on permaculture. The experience of wild food, for someone who was raised in a suburb in the ‘rustbelt’, is transcendental to say the least.

It is impressive what insight Brittany has been developing with her approach to flora and fauna, how she is learning by written knowledge and field experience how to break down many of the preconceptions western society has about food and medicine and the properties of life in this world. Oftentimes her perspective is similar to that of those we learned about in my Anthropology of Food class at the University of Akron, wherein the life that makes up the environment we live in becomes not something to exploit or harvest so much as something to be a part of, enmeshed in. Where we are to interact with it on a moment by moment basis, and what we put into our bodies transcends mere applications of nutrition and science but nourishes the mind, the body, the soul and becomes something to bring people together and connect us on the most nuanced levels to the world we are unavoidably a part of. Folk knowledge about wild food, wild medicinal plants and how to positively and sensibly interact with our environments is becoming resuscitated and reinvigorated, as food and other ecological crises mountingly face us in our day to day lives.

So, after pulling weeds in the garden and mulching some cabbage, we took to the well pipe. On the spot we made a robust, collaborative decision as far as the best engineering practice to encourage a well pipe with a lifetime design, based on immediately available materials. We used plastic pieces cut from a filter they had built before and that had not tested well to fix screens along four 10 foot sections of PVC pipe.

Though I had done similar kind of work before, doing it off the grid was a unique learning experience, and in retrospect the whole deal turned out to be an example of applied ‘participatory action research’. On the ground, those with a stake in the outcome the decision making process developed and implemented a design that best suited their needs, instead of being developed by some guy in a corporate office on a computer (though good things can be done that way as well). This seems to be a well rounded method for participatory open design of appropriate, liberatory technology. However, the problems caused by a “design for dumpster” well drilling rig they used resulted in problems with dropping that 6 inch pipe that we spent an entire afternoon putting together. They have since succeeded in dropping a 4 inch the full 80 feet. This is an important step in developing their infrastructure to be able to support more collaborators on the farm.


The next element to work on is to develop a more sustainable energy supply (instead of local waste veg oil) based on the PV cells donated by Ersol. You can read more below, but to update that post we will be soldering, assembling and encapsulating the panels in a few weeks based on our efforts and successes during this past weekend to research and develop a firm and robust action plan to ensure that the DIY approach will be successful and lead to panels that will have a long and fruitful life, considering the current capacity for fabrication work on the farm (no open-source, off grid solar encapsulation machines that I know of yet!). I and my friend Vince and hopefully others will venture out to take on this project while Marcin finishes the much anticipated LifeTrac (I helped him unpack an 800lb shipment of materials and parts into his new converted silo workshop). Once that and the panels are finished, they can use the tractor to run the CEB press mobile and use the energy to fabricate necessary parts and amenities for the new buildings and, in turn, support more folks. It is exciting to know that the co-laboratory is growing and that it is plausible that there will be as many as a dozen people living in a well established facility by this time next year, built brick by brick with CEBs and ingenuity. There is talk of a root cellar, full kitchen, fancy restroom facilities and a knowledge/resource library with a few computers, and smoke house for preserving widely available deer meat, among living accommodations and garden terraces.
Additionally, they have been in contact with some important folks in the free school movement, and the implications for the experimental blend of learning, living, research, design and application off the grid for the benefit of all is overwhelming to say the least. It amalgamates the ideas of Brazilian pedagogacist and political dissident Paulo Freire and the legendary social theorist and independent marxist Antonio Gramsci’s concept of the organic intellectual, combined with the general drive for liberated knowledge and participatory, grounded and practical learning (this is just my impression). This seems to be a just and sensible approach to educating ourselves and our progeny in the attempt to reach the goals of sustainability and resilience. In addition, to combine this movement with the appropriate technology movement seems to present a formidable partnership in the global struggle for self sufficiency and Swadeshi. The implications and readily possible results are enormous. Both movements have achieved so much already, and things are unmistakably in motion. As different active and concurrent fronts join forces and new approaches and concepts continue to emerge, develop and be applied, the possibilities for what we can create and live day to day will be endless. So for all of you who are out there sitting-on-ass, like I was only so long ago, its time to put our shoulders to the wheel and connect ideas and put them into action and live passionately for the future. Its high time we turn ourselves from passive consumers to active producers, from passive viewers to active participants, from those who abandonedly ride the increasingly volatile wave of change to those who harness it for the betterment of all. From farmers in India to factory workers in Malaysia to miners in Guyana to researchers, bloggers and activists in the privileged realm (not to leave out integral and citizen actors in the underprivileged realm), citizens of the world are crying out for change on all levels, and putting their inspirations, knowledge and ideas into action. It sure is a great time to be an ‘enlightened’ optimist, as those who are pessimistic about the future of humanity increasingly find themselves counterpointed by these concepts being put into action. So, let us achieve a world where the only times you hear the word ‘power’ are when talking about electrical things off-grid and empowerment (instead, participation, decision making, collaboration, etc.) , where the oppressed and the subaltern become mere historical anecdotes, examples of the injustice wrought by the disempowerment and malice of the past.
I can only look forward with ready hands and a reeling mind to further collaboration with Factor E and others in the broader global movement for Swadeshi. So much being done, so much to do, and the movement grows and grows. Abundance and Justice awaits.
