Re: [Biofuel] A chapter ends ...
Darryl, Thank you so much for picking up this ball! I have been reading for about 15 years with only a few posts, because I had so much more to learn than to say. I came to learn biofuel for my off-grid homestead. I got a broad education. Keith's perspective and this list have made the difference between my feeling overwhelmed and marginalized by much of our social direction, and gaining valid perspectives for inquiry. Thanks again, Tom Thiel New Hampshire USA On 12/31/16 2:54 PM, Darryl McMahon wrote: ... and another begins. I want to thank Chip for his efforts in recent years to keep the list operating. I don't really know how much effort that was (it was considerable when I last ran a list many years ago), but I'm grateful I did not have to look after that, freeing me to concentrate on content. I don't see this list (sustainablelorgbiofuel) as being much work for me. If I read a piece which I think deserves a wider audience, I simply shared it. I could just add it to Reddit or StumbleUpon or other such tools instead, but those do not save the content to make it searchable (in the mail archive). And while Internet searches are more comprehensive, they don't have a human filter to determine what is real and what is manufactured. In a world where perception and sound-bytes rule the mainstream messaging, I think that has value. In a world of Internet narrow-casting where feeds provide only reinforcement for pre-selected viewpoints, I hope that occasionally some of the posts I share cause others to pause and think for a moment. This was Keith's gift to me (and many others). I came to learn about biodiesel, and I learned about so much more. I have set up a new mail list via FreeLists.org. I have called this Keith's List because in my mind that is the most accurate and succinct description of it, though not everyone has known or corresponded with Keith Addison.

Re: [Biofuel] Paying for fire response service (was Alabama Town's Failed Pension..)
One element that serves to equalize the decision forces is the cost of insurance premiums. A homeowner who chose to opt-out by not paying the annual fee would face fire insurance cancellation, astronomical premiums or non-collection of damages upon investigation after an unprotected fire. If an institution (the bank) holds a mortgage on the house, it would require fire (and other) insurance which would require fire protection. Such forces serve to overwhelm the majority of people's potential decision to not support the local fire protection service. Common-good systems require participation by all affected parties. Withdrawal from a system is something that an adult might choose. Such decisions have real consequences. This scenario brings such consequences into clear focus.

Re: [Biofuel] Fwd: Working with the Worm Gang
Consider investigating Borate as a wood preservative. Salts of Boron are formulated for osmosis into wood leaving behind a sharp crystalline residue which kills organisms as they invade the wood. It leaches very little and is not chemically active. Brands such as Tim- bor, Bora-care, Board Defense and others all provide the same ingredient. It is mixed at 10% solution, best on green (undried) wood, but can be used on dry wood. Borate is also available as a solid plug (as Impel Rods) which dissolve only when wood moisture exceeds 18% which is when rot organisms would begin to thrive. In either case. Whether or not Borate is used, I suggest NO finish, neither linseed nor tung oil or other. Finishes only work when the surface can be dried by hand, sun or wind. A damp surface in contact with ground will stay wet. Finish will not help and may harm by keeping wet wood wetter during conditions when it might dry a little if unfinished. Another idea is to use a wood that is naturally rot resistant. Local wood guys will know what woods work in contact with soil. In the USA we use Redwood, Cedars, Black Locust, Mulberry, Osage Orange and others. It's fun to investigate and find these treasures.

Re: [Biofuel] Treated-wood woes - Watch out for pressure-treated products
Borates are readily available in much of the world and are turning up even in the USA. Search for Boracare, Board Defense or Tim-Bor. Also available as Impel Rods, a solid the size of a finger which is placed at the ground line, overhang, etc. and remains inert when the wood is dry and slowly dissolves if over 18% moisture content, supplying preservative only when / as needed. Note the Sodium Octoborate is effectively nearly chemically neutral; its fungicidal (etc.) action being a result of its micro-crystalline structure, which is small enough to osmose into the wood, especially if treated when green. Stuff that eats the treated wood dies by abrasion/laceration. Friendly agent.

Re: [Biofuel] interesting refrigerator
Hi Tom, Thank you so much for your post. We've been "way back" for 5 years and the decision tree is quite different from that of the plug in culture. Regarding refrigeration: it is a significant energy user and when watts are precious we take notice. My solution is quite simple in our cold climate of Northern New Hampshire USA where it is colder more than warmer than refrigeration temperatures. I put the refrigerator in an insulated cavity on an outside wall with vents (manually operated) to allow more and/or less access to outside air. The primary purpose of regulation was to keep the refrigerator from freezing. Since the refrigerator itself is also insulated, it averages temperatures over time and freezing has not been a problem, so vent operation is very minimal. In summer the (normal electric) refrigerator blows its waste heat (and noise) outside. Spring and Fall, the compressor sometimes comes on and works efficiently against cool outdoor temperatures. I'm installing a small chest freezer using same principles. I had ruled out a freezer due to excessive power consumption before the "north wall" concept. Small, personal innovation can produce satisfaction beyond savings. How nice that is.

Re: [Biofuel] WVO in Diesel Generators
Regarding starting motors in our off-grid woodshop: we treat 1 horsepower motors as intermittent-use, starting and stopping them at will. Larger motors are paired with a 1 horsepower motor to start each machine. After it is up to speed, the main motor is turned on. This system reduces the start-loading of the large motors almost down to full load amp rating, and its elapsed time to less than a second, since the rotor is already spinning. If he has an inverter / battery system, the battery bank will charge variably as (headroom) power is available, reducing the light-load wet stacking potential in the system. I await the SVO discussion with great interest.

Re: [Biofuel] diesel generator
Hi Zeke, If you calculate the relative power per wattage of single and three-phase motors, there will be a slight advantage to 3-phase. The value of 3-phase motors also extends to their better torque and start-load characteristics and lack of starting capacitor(s) to maintain. I would base my system on availability and overall usefulness rather than those relatively modest advantages of 3-phase motors. A single-phase, dual voltage (as in 240 / 120 volt in the USA) setup allows use of higher voltage for motors and the lower voltage for appliances and lighting. Single-phase inverters are the norm for converting stored Direct Current energy to useful Alternating Current power. You're on the right track to run your generator while running your motors. If you have inverters, they can augment the output of your generator to help with start-loads (up to 5 times the run-load of the motor). The battery bank can be charged by the excess generator power and by photovoltaic, wind, etc. at all times. In capturing generator heat, don't forget the waste heat of the exhust stream, harder to capture than the coolant heat, but about equal to it in power. Good luck with your project.

Re: [Biofuel] Hydropower doesn't count as clean Power
A precedent could be examined at Alloy, West Virginia, USA where Union Carbide built such a project in the New River Gorge many decades ago. At a loop of the New River considerable vertical drop (perhaps 1000 feet) was harnessed by boring a tunnel through the mountain ridge to rejoin the river several miles downstream. The outlet of the tunnel houses a turbine power plant. This plant has been operational for many decades, so those interested could gather facts regarding its cost per watt generated and various ecological considerations and outcomes. Such a project seems to have lower impacts than downstream dams and installations which adversely affect fish migration, create flooding of valleys, and introduce potential dangers from dam failure to toxic sedimentation. This project became feasible due to point of use generation for a large induction furnace to make technical metal alloys requiring clean firing. If, on the other hand, the power had to be transmitted long distances, the economic and ecological profiles would change considerably. Among those added costs would be intangibles such as environmental and health factors from transmission magnetic fields, disruption of backland ecosystems and the like. The assessments which make it to the light of day generally ignore large aspects of the complex equation of real costs to real benefits ratios. If all of the costs and impacts were accounted for, I think it unlikely that any large, centralized project could be honestly justified contrasted to distributed generation by low impact technologies such as photovoltaic and wind generation at point of use.

Here in the Northeast US, I have chosen to build with wood, often reclaimed from deconstruction operations; and I prefer my constructions to be resistant to termites, carpenter ants, fungi and other organisms that degrade wood. I also prefer to avoid chemical migration into my little corner of the biosphere. I have chosen to use Borates as a wood preservative strategy. Borates are derived from mineral Borax, ground and prepared for absorption into wood. The mineral itself seems to be quite benign, not chemically reactive. Its form however is a sharp micro-crystalline powder which is dissolved into water and absorbed by osmotic action into the wood. Most effectively applied on green (non-dry) wood by spray, dip or brush, but also effective to shallower penetrations on dry wood. Anything that eats the treated wood gets cut by the sharp crystals and dies. The borate penetrant does not form chemical bonds with the wood and is thus susceptible to leaching; but it is surprisingly persistent in the treated wood. Another form is a pressed cylinder of various sizes, set into a drilled hole in the wood in vulnerable locations such as ground-line or direct weather exposure. Generally looks like a cloudy glass slug the size of one's finger. These rods are self-regulating, remaining intact in moisture concentrations below 20% (where wood is quite resistant to microbial decay action) and slowly dissolving at greater than 20%mc. Borate technology is quite mature, being used by utility companies, etc. around the world for over half a century. The USA is a very late adopter having preferred seriously toxic industrial alternatives. A google search of borates generates considerable information including brand names such Impel Rods, Bora-care, Tim-Bor, etc. My research and personal experience find nearly identical products with very divergent pricing with "Board-defense" being a low cost champion. Handle with care, the powder is an irritant and the liquid will kill your gut bacteria. But on the bright side, there's no harmful fumes or outgassing. Tom Thiel > > Don't build from wood.
