August in Brief

First planted sunflowers - the three that survived the slugs in the spring -
now with lots of nice ripe seeds. a 9 and two 11 inch diameter heads, ready to harvest.
Others are farther behind. (And the caterpillars have been fierce!)

   Where have the energy projects gone? In the spring, gardening took my time, and I am harvesting food to eat now or for cool storage, the freezer or drying. Next spring might be a little easier, but I do want to extend the garden by the house. Some things just grow better there - more sun, a bit warmer.

   In the summer in the nice weather I spent much time working on my metal clad cabin. (metal: electric field dampening; fire resistant.) Every time the sun shone, which was lots, I was just itching to get out there and do more. The lawn grew long and shaggy and dishes got done when I ran out of clean ones. Well, so much for excuses.

   Now autumn is arriving and (after hopefully putting up the last two wall sections and then catching up on a lot of put-off things) I should have more project time.

   My present project thoughts for this winter are on two main ones: the unipolar axial flux BLDC motor (and, sigh, its six phase unipolar motor controller), and the new chemistry batteries, this time made as plastic pocket electrode cells. The pockets hold the electrodes compacted and the cell is unpressurized, so they shouldn't spring leaks.

A Better Peltier Module?

   I'm also rather interested in trying to make a better performing Peltier module with beryllium oxide ceramic instead of alume oxide, since no one else seems to have tried it AFAICT. (The beryllium company hasn't replied. How do they expect to get new industrial orders if they won't respond to those wanting small R & D orders to develop new products?) If indeed no one else has done it, it should (theoreticly) make the world's best performing Peltier module. My main fabrication worry is how to deposit solder (or ? metal) onto the ceramic. I've never looked into that. Hmm, wait... I once deposited silver onto glass using silver nitrate (a telescope mirror in 1974), so maybe that? (Silver is also a fabulous heat conductor!) The small parts may also be daunting to work with by hand. I can't find the little square thermocouples used in Peltier modules to buy, but I can probably just disassemble (melt open?) a couple of modules and get some out.

Magnetic Variable Transmission/Truck

   In the little time I've made for this this summer, in July I fitted the copper rotor and found it was badly unbalanced and caused horrendous vibration. So this month (August), I ground some high spots and areas off the copper rotor's magnet face so it could be generally closer to the magnets, then bolted a steel weight onto it to balance it. It seemed well balanced.
   It wasn't until September 5th that I put it back on the truck and tried it out. There was much less vibration, but still far too much to try and take a drive. I clamped a video camera on the side to see underneath and ran it again. Even at the lowest speed, the planetary gear and rear driveshaft were shimmying back and forth as the gear body turned. After a couple of minutes reflection I realized that the steel weight on the copper rotor was pulling the Hallbach configured supermagnet rotor toward itself on one side, and there was enough play in the shafts & gear to cause the shimmy. (Maybe if I had put in that second steady bearing?) It was no longer unbalanced by weight, but instead was magneticly unbalanced. I'll have to replace the steel weight with a copper one.

   Another disappointment when everything seems Soo close to working great, for so many months! (I'm still astonished that I couldn't simply buy a small piece of pure alume plate - not even 1/4 inch, let alone 1/2 inch. Then I got the electric furnace and some copper pennies, but casting a copper rotor also proved trickier than expected and cost still more time.) And going under the truck disassembling and assembling every time I try something new holds me back - it's hard on my back and shoulders. Well, at least it's in a cement floor garage and not outside on gravel or lawn! And it's getting easier with the recent progress on the housing, which I can now leave in place and just pull out the mechanism. (More details)

Fires: Another Reason for Metal Walls on the Cabin

   The largest forest fires ever in BC and the Canadian Arctic as well as in Siberia blazed away to the east, west and north of me, and IIRC there had been a couple on Vancouver Island too. I have been content to just say "I'm sure it won't happen here." Then (youtube) I watched a couple of climate scientists being interviewed (one was Paul Beckwith from Ontario) and talking about events that gave premonitions of how bad things might get in the next couple of decades. But it was the fire in Lahaina on Maui that I suddenly thought of.
   The cabin I'm building has metal siding and a metal roof. It's in a field. Some moderately nearby small trees and brush can be cleared. I finished the third outside wall on the 24th, using up all but one full piece and some scraps of the siding. (I'd have had three pieces left if I hadn't made a couple of wrong cuts. I'd have had enough for all four sides if I hadn't used some for the carport roof. It seemed like there was so much when I bought it!)
   I'm ordering an insulated metal roll-up garage door for part of the last side. Now I'm determined to do the last wall also in metal or other fireproof material, and to cover up all the open wood with flashing or something. This summer we've been less dry than the rest of BC, but If there is a bad forest fire here, it just might be one of a few things still standing for miles around. Such are the times that this should seem worth pondering! August's cabin construction in pictures.

   The next day I looked at my washing machine and (at long last) put an alume anode rod into my hot water tank. The previous tank had had no rod and started leaking about 5 years after I bought the house. The previous owner had suggested I bring a new tank when I moved here and I did. But the well water, with a zinc anode rod, stank to high... wutever... so I had taken it out. I had the same problem with the small 'solar' tank I had put under the kitchen sink a couple of years previously, but I didn't understand the problem and ended up taking it out entirely, switching to a 3KW "on demand" unit... which provides just a trickle of hot water for dishes. Finally I thought to try an alume rod, and however much or little protection it gives, I don't smell anything. (Oops, spoke too soon. I can smell it when I start a shower. But it's not half as bad as with the zinc. I think I'll keep it.)

Masset Airport Solar Power: Winter Sun Angles

   I had asked to be involved in this megawatt solar project with batteries to even out the power. Mostly I thought the angles didn't look right in the presentation at the energy conference last March. It should be noted that when any one cell on a solar panel is shaded, the whole panel puts out nothing. If sets of panels are connected in series, one shaded cell anywhere kills the whole string. Somehow my emails after the first one went unanswered, and the panels were installed over the summer.
   Finally I went to the airport and saw it, through the fence from the far end of the field. As I had feared, the rows looked to me to be too close together for the winter sun, which at 54° north latitude is quite low, 12.5°. They may or may not have been spaced far enough apart for noon at the winter solstice, but surely not for any other time of day when the sun is even lower. So they will produce very little in winter, even less than the short days should allow. And there was lots of room to space them out more - the empty grass field runs the whole length of the runway. (The panels were also only tilted about 30° to the south by my estimate, which is less than optimum even in summer. Latitude angle is 54° and probably 35°-45° should have been more optimum. That's a more minor point. A 30° angle cuts the winter output to 70% of full potential, where 40° gives 79%. And in a cloudy winter sky if there's much to be had at all, flatter sometimes seems better.)

Wind Power on Cargo Ships

   The last time I remember hearing about putting sails on cargo ships to save fuel and decrease the pollution was quite a few years ago if not a decade or two back. They were a solid wing shape, three or four on the vessel. It was said that they saved considerable fuel and made the ship more stable and comfortable in heavy seas, damping out the back and forth rocking motion. Somehow that didn't seem to catch on, since I haven't seen one with sails since.
   Now someone has brought back the concept but added some moving parts to more optimally shape the sails for the wind conditions. These ones are taller, I think, and there are just two. We see they are mounted off to the side, presumably to be out of the way for loading and unloading, which cargo ships spend a lot of time doing.

Ship Fire: Wasn't a Lithium Ion battery?

   Concerning last month's news item, the fire on the Freemantle Highway car carrying ship probably wasn't caused by a lithium ion battery of an electric car. Evidently someone suggested it and news outlets jumped on it as "fact". They don't know (yet?) where it started, and cars below deck 5 were undamaged, including many EV's.
   The cars were neither in use nor being charged. Batteries at rest of any type are generally pretty safe. Evidently the one case where an electric car's lithium ion battery is definitely known to have caused a ship fire was a home converted EV being charged on board on a ferry. And the exploding Chinese e-bikes seem to go off mostly when being charged. (They probably have really cheap, primitive chargers. Car makers go all out to make the charging as safe as possible, monitoring each cell, slowing the charge for the last 10 or 20 percent and definitely cutting it right off when full.)

   Lithium iron phosphate batteries still seem a lot safer than lithium ion or lithium polymer.

The Cause of Tinnitus: AC Power Fields

   "Microwaves" (actually centimetric wavelengths, not micrometric. gigahertz frequencies.) need a very fine screen in the oven door's window to keep them inside. (Let's not get into radiation harm from cell phones at similar frequencies here!) And they pretty much travel in a straight line: if there's anything to block microwaves between their source and you, you won't get any. Let's see, wavelength at 60 CPS is (speed of light)/60 = 286282 miles/sec / 60 = 4771 miles or about 7.6 megameters. For such long wavelengths, the 2 inch mesh chicken wire, or stucco wire, should be plenty fine. The other thing such low frequencies do is bend well around corners. (There is much said about this in stereo speaker cabinet making and design.) That means one can't just have a sheet of metal somewhere between the source and yourself: the field will just bend around behind it.

   Since my one and only lengthy experience away from AC power and power lines in about 1991 would indicate that it takes days for my tinnitus to fade to "insignificant" or "gone", I don't think I'll eliminate it except by spending most of my time outside of or shielded from power line EM fields.
   So that's the "bubble" of chicken wire mesh at the head of my bed, the metal lined cabin when it's done (with no unshielded 120 VAC inside), and an electricly shorting helmet most other times. All preferably grounded to really short out the field. I will probably never be able to maintain "no tinnitus" as long as the power grid is on, but I can probably go with this regimen enough days to prove it does go away or at least fade if at least one's head stays out of power line fields for so long. [By early September I had some great evidence!]
   The tinfoil "helmet" has its problems. It's fragile, and it blows off my head in a light breeze or even if I walk too fast. And there's nothing over the face. I ordered a motorcycle helmet. My plan is to line this with alume, either tinfoil inside or alume tape on the outside. Then it should have an electricly conductive face shield. The plastic won't do a thing. I suppose this could be wire mesh, but I'm looking for conductive, transparent coatings or films (CTF's), probably the polymer coatings rather than indium-tin oxide metal types. A spray-on bottle would be wonderful! (Can anything be added to transparent polyurethane spray paint?) Or perhaps I could make a very thin coating of silver, made with silver nitrate as with coating a telescope mirror?

[21st] Never being rid of ringing in my ears, I wasn't totally sure the chicken wire mesh 'bubble' was helping. Even in the mornings before arising it was sometimes still pretty bad. But on this morning I woke up with the loudest tinnitus tone blasting strongly again. It seemed like it was no help at all! I opened my eyes, and found that after getting up in the night, I had gone back to sleep with my head outside the 'bubble'. So if it wasn't making it better, not using it certainly seemed to be making it worse!

[24th] In bed in the morning when all is quiet, and under the metal mesh, I lately have been hearing a mid range tone, which vanishes when I get up. I've heard it before when I lived in Victoria. This time I fetched my flute, and figured it was between C4 and C#4, perhaps closer to C. When I was up and looked these up, about 523 and 554 Hz. FWIW 540 is the 9th harmonic of 60 Hz.
   Listening for the very low tone that I usually only hear when I'm overtired, I could hear it, very faintly. But checking with my flute and looking up the frequency, it seemed to be maybe G1, which is 52 Hz rather than 60 Hz. But transposing down three octaves is rather sketchy. Pretty hazy observations! [Later tries said 60 Hz.]

   I found an on-line signal generator. Yikes! My hearing is getting really bad above around 6000 Hz. In high school it was already down to 15000 Hz when others could hear to 20000. (Must have been the loud shotgun from when my dad would take me duck or pheasant hunting when I was four & five years old.) Well, hearing loss is certainly a major factor in tinnitus too. Even with electric power, apparently there's usually no tinnitus without hearing loss. My tinnitus started intermittently when I was maybe six or seven.

   It is frustrating that any effects one way or another are SO slow to discern, and that it's not possible to take many definitive, objective measurements.

   I finished putting the metal siding on my 3rd cabin wall. Now the only wall still open is the west wall facing away from the power lines. Inside it must be pretty quiet electricly by now. I thought or imagined I could feel some relief sitting in there reading a book.

   Then in the evening Perry with increasing tinnitus phoned, raving about Nicorette gum. (His was acquired just a couple of years ago after rifle shooting without ear protection.) His girlfriend had run across something on line about nicotine and the gum for tinnitus. He had been chewing it for just over a week, and said it had greatly reduced his tinnitus. He said you only use it for two weeks, once in the morning and once in the evening, and then stop. It sounded like it was worth a try! (I got him to pick me up a package at the pharmacy, since it would be almost a week until I'd be in town when it was open.)

[27th] I started the gum, one piece in the mornings and one in the evenings as he had said. I didn't notice any "upset stomach" that was said to be a possible side effect. My brother warned me about nicotine addiction. I figure it won't happen - I'm not smoking it, and I'm not about to start smoking at my age! If there are withdrawal symptoms after the two weeks I'll have to deal with them. I continued using the chicken wire bubble in bed. Usually I would put on the pizza pan helmet after I got up and suddenly would notice the high frequency tone hit my ears, but it still wasn't possible to wear it much of the day when I was active.

[Sept. 1st] There was a clue I hadn't thought about before: if I stay up way too late at night, I start hearing - and in fact feeling - a low vibration throbbing with my heartbeat, inside my head somewhere near my right ear. It then lingers until I get to sleep. It wasn't happening at any other time. It wasn't happening at similar times of night if I woke up from sleep that I was aware of. I thought it was just internal noise since it seemed to only happen when I was overtired, telling me I should get to bed.
   It happened again in August. I started wondering why my body should ever have a strange low vibration. What was it related to? I suddenly suspected that it was always there, usually unfelt and unheard, just under the threshold of awareness - and in fact that it was the continuous audio irritant coming from the power lines, that somehow reacts to make the ears ring at high frequencies, similar to after hearing loud music or power tools for a while. But because it's always there, it probably doesn't have to be very loud and the ringing never ends: tinnitus.

   Since sleeping with the steel mesh bubble at night and often wearing the pizza pan "helmet" in the day, I sometimes also started hearing this tone, more faintly, when I woke up in the morning and until I got up. (And could hearing it be related to the gum?) It was easily drowned out by anything including the first exertions in getting up.
   On September 1st AM it was quite noticeable in bed, and after I got up I relaxed in a chair. The vibration/sound reappeared. The volume varied even with my heart beat. I tried to hum the frequency and went to the on-line audio signal generator site I had found. While I felt unable to judge very closely, when I generated tones to the speakers, my best guess was 60 cycles per second: that it was indeed the AC power lines frequency.
   Then I walked out into the woods behind my house, around 400 feet from the house and 500 from the power lines by the highway. That was surely far enough away from any electric power to be pretty quiet. I sat down on a log and again relaxed for a while until my heartbeat and breathing were quite at rest. And when there were no cars going by and all was quiet, I listened. For all the high pitch tinnitus whistles ever ringing in my head, I couldn't detect the low tone. I went back to the house and sat in the chair again. Sure enough, the low vibration/tone came back. So I went back out into the woods and rested again. No tone, twice!

   If I can repeat this technique, it could be an objective, if faint and variable, technique to determine the presence or absence of power line hum at a given location, regardless of the extreme lengths of time it takes the high pitched tones to react to that, to increase or fade. The fact that I was hearing it in bed says the chicken wire mesh "bubble" isn't cutting out all the power line noise. This is understandable since the lower end is wide open, not close around the neck. (more of a "somewhat open clam shell" than a "bubble"?) But using it and the metal helmet for some days seemed to reduce my tinnitus enough to make me more sensitive to other tones, which had started coming and going and changing. The loudest piercing tone was much reduced or I probably wouldn't have heard (or noticed) the others even if they were there. Especially I had never consciously noticed the 60 Hz in the morning before.

   Places I can start checking out for "electricly quiet" versus "noisy" via this tone:

* Different distances away from the house and power lines: how far away is "far enough"?
* The cabin with grounded metal roof and walls
* My "pizza tin" helmet, ungrounded or grounded with a wire while I sit
* of course, the helmet has no conductive face cover, so it might give different results facing toward and away from the power poles.

   A question might be "Is the noise coming from the AC lines acoustic or electromagnetic in nature?" After all, wires in transformers hum quite audibly, sometimes even loudly, at 60 Hz and harmonics of that. And as I've found out to my distress, wires not solidly glued down in motors vibrate until the insulation wears out and it fails. Do all the AC power wires everywhere vibrate and hum to some small extent, that is only subliminally noticeable?
   This seems like an attractive theory, and it may well explain part of the problem. My brother once complained to the city that a buzzing streetlight outside his window was making his ears ring. (They changed the transformer.) But it doesn't explain everything. Why should my tinnitus gradually get louder driving in the car under the high voltage power lines? (...any car but more noticeable in a quiet electric car - I first noticed it in the converted Mazda RX7-EV and thought it might be the car. But the power electronics of the car is virtually surrounded by metal under the hood.) With the car windows closed, outside sounds are largely blocked out. So I'm going with the theory that it's 60 Hz electromagnetic interaction coming right through the non-conductive windows and into the head, and impinges on some part of the the auditory system, mostly unnoticed, but which reacts to cause the tinnitus.

[Sept 2nd] I was talking about it to a friend and he said he felt more than heard a low vibration whenever he went out to his shop, which was full of 240V power tools and very close to the street power line. Evidently he hears it much more than my "seldom" and "right side only". And he said having ears ringing from using noisy power tools was somehow different from his tinnitus. He also said his tinnitus goes away when he puts in his hearing aids - Lucky guy? If the AC electric power field is somehow making something inside the head and the ear actually vibrate, it's probably not a wonder that it should aggravate the hearing system, which seems to manifest as tinnitus.

[Sept 3rd] I seemed to be hearing/feeling the throbbing 60 Hz tone more and more (perhaps because the high pitched tones weren't as loud with my weeks of dampening experiments?), and it was clearly back on this late evening. I went out to the cabin where presumably the electrical noise was dampened and sat down for a bit. But I heard it. I even disconnected the cord to the solar power grid ties and put it outside, eliminating even the few feet of 120V wires inside. Was the metal siding and roof really damping it? Did the field from the 14,400V power poles just come right around the far side, bend right around and come in through the open end? (Was all of the siding well grounded? Anodized alume might not necessarily conduct well between sheets.)
   So I took a flashlight and went back in the woods again. This time I could still hear/feel it there, too! This contradicted my previous test. But it was still the same electric power frequency. Just how far did one have to be from the power lines? (I probably can't get any farther away on or near my property owing to power lines running down the side street a few hundred feet away.) Or was the low tone just "still ringing" like the high tinnitus tones?
   The power of the electric field must suely be several tens of decibels weaker in these more favorable locations, but in this day's listenings I couldn't tell. (No dB meter inside my head!)

   The wire mesh "bubble" around my head on my bed certainly seemed to help, but it wasn't comfortable or convenient ducking my head into it to get into or out of bed. I finally removed it, and by morning the highest, piercing tinnitus tone was again as loud as ever. The motorcycle helmet arrived, but it seemed too heavy for day-long wear. The alume "rectangular pizza pan" helmet is very light and except for not having a conductive face shield and a chin strap to keep it in place when working, is probably about the best and least annoying thing to wear. The nicorette gum doesn't seem to have make any difference so far. (I don't think I'm becoming addicted to the nicotine since I keep forgetting it. I'm two chewings behind in a week.)

[Sept 8th] There's a natural area some miles long along the highway with no power lines, a space between the island's "North Grid" and "South Grid". I stopped there and meditated for a while. I didn't hear any low hum. Then I stopped at a friend's by the highway with power, and heard it almost as soon as I stopped the car. I haven't heard it again sitting in the cabin, but I have in the house.

   That may be all I have to say on this until the field-dampening cabin is completed to the extent that I can spend living time in it.

Scalp Mites/Hair Loss: A Factoid - Exterminating

   I watched a video about Demodex mites and treatment from a bald guy who says he got rid of them too late, but he seemed to have done much study. He seemed to have his own brand of treatment products, so perhaps he hadn't run across alcohol. Too simple! It was implicit with him that the mites were the cause of thinning hair and baldness. (Sounded like it was just one of his many videos - perhaps he went into explanations in another video(s)?)

   The most important thing I learned was that he said the mites can live up to 52 hours off the host - apparently an unusually long time for such a mite, and he spoke of "cross contamination". When you treat your scalp, at the same time you should change your pillowcase(s) and any hat, tuque, scarf et cetera you've been wearing, and not use the same one again for a few days. Also maybe squirt alcohol on anything you often rest your head on, such as couch cushions, the back of a couch or easy chair, and your comb or hair brush and... These are ways that the mites keep coming back so quickly, and spread from person to person.
   Daily shampooing and leaving the shampoo in for the duration of the shower took too much time and I wasn't getting to it often enough. My hair was thinning badly - headed for baldness all along the top by 2020 (at age 65). I bought a bottle of "Rogaine" and discovered that the makers didn't know how it worked. But it had to be applied to the thin spot pretty much daily to work. Of course it did - the mites would come back from all sides in no time! I saw that one of its ingredients was alcohol, and I suddenly realized that that was what helped, not their "secret ingredient" - it killed the mites.
   So now for 3(?) years I was spraying my hair/scalp weekly with an atomizer, preferably with 50% diluted (ethyl) rubbing alcohol. (A vodka scalp rub (40% alcohol) has been used by some - who mostly don't know why it works.) I recently went to twice a week, since my hair, while recovering considerably, hasn't come back to full thickness.
   But I kept putting on the same tuque even right after treatment, and I wasn't changing my pillowcase or bed sheets. Maybe using this new info they'll be much slower coming back, and treating once a week would be plenty? Or might I dream of eliminating the nasty mites entirely? My prospects should be good since I live alone and I'm not doing a lot of partying or travel. Wouldn't it be cool if no one had them and baldness was a thing of the past?

Hot Weather Ahead

  Climate scientists project that we are at a point where even if all "fossil fuel" emissions were drasticly cut today, temperatures would continue to rise for about two decades.

   I think we should start by cutting most jet aircraft traffic. In addition to the exhaust from fuel they burn, I'm pretty sure the long-lasting jet trail "atmospheric blanket" clouds they're generating in the stratosphere are the worst part of the whole climate change thing. I've detailed the enormous effects of this in terms of the disruptions of global wind circulations plus severe droughts and their corollary, "rivers from the sky" precipitation before. Personally, I think the temperatures would stop rising sooner than in 20 years if those clouds were eliminated.

   Until now, cold has been thought to have been more of a people killer than heat. But apparently heat deaths are greatly under-reported. People suffering from heat often have heart attacks and other conditions that are the listed cause of death - but they wouldn't have died except for being too heat stressed. Now the record heat waves of recent years are increasing and lasting longer. Climate scientists are pointing out that when it's hot enough for long enough, it's no longer just discomfort, it's "cool off or die". All that's needed are for overloaded, poorly maintained electrical grids to fail in heat waves for people to start dying en masse, especially in the "heat islands" that are cities. This is just one more reason the global population is expected to shrink dramaticly in the coming decades.

   On a related side note, in the killer cold in Texas in Feb. 2022, when the power grid had to be cut making "rolling blackouts" and people froze, many were griping about how useless solar and wind were and that the money would be better spent on plants that use fuels we're running out of. But in this summer's killer heat, the grid was stable even with the extreme cooling loads because 25% of the power was coming from solar panels. Otherwise it might well have failed again. (And I've been thinking why Wouldn't you power your air conditioner with solar? Unlike with heating, when you need cooling most is just when the most power is available.) Thumbs up for solar power in Texas!

   So far air conditioning is virtually needless on Haida Gwaii. We've had a nice summer with 3(?) weeks where people complain it's too hot to work outside because the sun is shining and it's 26°. (79°F) Aw!

SUDDEN SEA LEVEL RISE (it's coming!)

   Last month I showed a graph of the amazing reduction of the extent of Antarctic sea ice *this* year, quite different to any previous year recorded. I have heard of projections (from Spirit beings - "celestials" - angels and other groups) for rapid, almost sudden sea level rise owing to melting ice there and on Greenland. Heretofore I couldn't imagine the mechanism for such a rapid pace.
   But we seem to have hit a tipping point. Here is a video that gives a simple reason: "atmospheric rivers" of snow falling on Greenland (and probably Antarctica - if not this year, then coming up) have turned to rain, rapidly dissolving glaciers. These would be the same sort of "atmospheric rivers" so noted in recent years for delivering, eg, a month's worth of rain in a day and washing away homes, cars and livestock - pretty much anywhere in the world. (Around mid August large areas around Beijing/Peking China were flooded into second story depths. That was not the only serious flooding during the same period while other regions (Canada, Siberia, Greece, Maui) had monstrous forest fires owing largely to drought.)
   I have explained before how the persisting jet trail clouds (intentional or not) would blanket the atmosphere up into the stratosphere where clouds are usually rare and thin, which hence make it warmer up to those altitudes, disrupting the global winds:
   [TE News #109, #110, #129]
   The warmer air can then hold heavy moisture up to (eg) 30,000 feet instead of 3000, which would explain why rain doesn't fall when and where it's expected causing droughts, and when it does, there can be such heavy precipitation as to cause devastating flooding, or record breaking hailstones or blizzards.
   The temperature is a tipping point. With that sort of sudden, intense rain falling on the glaciers instead of snow, well they may melt with cataclismic speed, suddenly making clear the cause for the projections.

"insane flooding rain to Greenland - rapids in an atmospheric river"

   After watching this video, Youtube came up with a bunch more suggestions: "Antarctica's Tipping Point, The Science of Ice Collapse", "Record Ice Loss" in Greenland, "Emerging Tipping Points in Antarctica"...

   As one can see from my past newsletter links, I disagree with some of the author's conclusions. In particular Box blames Arctic warming on greenhouse gasses, then says this Arctic warming is causing a slower and wavier jet stream. I say the reduction of the impetus that drives the global winds - the decrease of the temperature drop with altitude in the troposphere owing to the blanketing by the persisting jet trail clouds - explains the slower, higher altitude and more chaotic jet streams, which in turn often allow warm temperate zone winds to blow into the Arctic, causing Arctic warming. (And then in compensation cold Arctic winds blow down into the temperate zones, notably during winter, and we get extreme cold and snow as far south as the tropic of Cancer - eg, Texas or Arabia.

Scattered Thots

* On longevity: Do you think of physical exercise time as "lost time" from your life? A 100 year old doctor said "Every hour you exercise adds three hours to your life." So instead that would be two hours "gained time". Potentially.

* We're all equal in spirit and we should all treat others as we would have them treat us, but we are all different in many ways. Here Thomas Sowell (most always worth hearing) goes into what many may think of as "racial stereotyping" in choices of occupations.

Thomas Sowell Exposes Economic Truths You've Never Known

* I mentioned a couple of months go that the very low birth rate among white people most everywhere since the introduction of the birth control pill in the 1960s and more especially for the last 30 years, combined with massive influxes of other peoples, has led to us dropping swiftly to near and below 50% of the population and becoming a minority, in most places globally. A great percentage of white people are now too old to have kids and as we die off whites in the next generation will be well below 50% of the population. I think we are presently disappearing as swiftly as the North American red man tragicly did between 1550 and 1650 with an estimated 90% population drop.

   I also note that China and Japan have had similar low birth rates for about the same period, perhaps even more so. The difference is that they aren't having an influx of immigrants like the West. However much their populations drop before stabilizing, they will largely retain their racial identities and continuity.
   A presenter said reasons for low immigration to China even with dropping populations were fourfold. First, the dictatorial government. The present leader seems to be as authoritarian as Mao Zedong, with highly deleterious effects on the previously booming economy and society. Why would people go somewhere where they have less freedom instead of more? There were a couple more reasons that I don't remember (increasing unemployment? more benefits in Western countries?), then finally that the racial prejudices of the Han Chinese made foreigners quite unwelcome. He talked of "deflation" and "economic collapse" in China from the dropping population, and saw it as a terrible problem, whereas the West has "circumvented" the "problem" with massive immigration. I think that in a world of eight billion people that can probably sustain three, any drop in population now - or any reduction in the rate of population growth - is that many fewer people who will die tragicly in various ways as we smash into the end of our depleting resources and ransacking of the ecology. And fewer people should need smaller economies, so I don't see dropping population as an economic problem.
   Who does? Our financial pyramid scheme institutions make bankers rich by continual expansion and growth, and to them a dropping population - or even stability - is a disaster. The financial system can't shrink without drastic consequences. So somehow we have been taught to think of "neverending economic growth" as a good, even vital thing. By other metrics, population and economic stability is a blessing and 60-70 years overdue.

* Surely the white races have contributed much to the modern world even with all its faults and all our faults, and the rapid disappearance of nearly all predominantly white societies from the planet over a couple of generations seems to me to be a biologic and cultural misfortune. For that I am being labeled by some as a "white supremacist". I am for the social and educational improvement and enlightenment of all, and for the genetic and epigenetic improvement of every race as we learn more about genetics, by means of family planning - by the education and free will decisions of individuals and couples themselves, with the promotion of favorable human genetic traits as they become apparent. With good birth control now available, most children will be wanted children, not "accidents". General genetic improvement and weeding out of defective and inferior genes has been done for most every domestic species, but not for us humans ourselves. Societies are a product of the people who compose them, and superior peoples will make a superior civilization. "Homo Sapiens" must evolve into "Homo Spiritus" as well, not gradually degrade itself.

   I will content myself with the thought that "All things work together for the progress of men and angels." and that in the course of Christ Michael's thousand year "Correcting Time" plan just getting underway, everything will work out well and that the world of his mortal sojourn will have a glorious future.

* In the fire in Lahaina on Maui, authorities told people to evacuate by car, then the police blockaded the only highway out of town! It seems up to 2000 people including whole families perished, some sitting in their cars waiting for the line to start moving, while others spent up to 8 hours dog paddling in the ocean to escape the inferno. There were no sirens, warnings or alarms, and many didn't know the town was on fire around them. Other oddities included water being turned off, hampering firefighters. Various excuses were made, but rumor has it that it was not mismanagement but a ruthless land grab by those in power. President Biden said "No comment." on the fires, and apparently fell asleep when facing residents. Residents were offered 700$ each (!?!) for compensation while numerous FEMA personnel were flown in and put up in 1000-2500 $/night hotels. Last I heard no one was being allowed back in (even to unburned homes) and news crews and drones were being forbidden access and chased off. The homes were valued at nearly a million dollars each on average, and if the houses were gone and the legitimate land owners were nowhere to be found...??? Are these views real, or was it just a string of tragicly botched, negatively miscoordinated responses to an accidental fire?

   "in depth reports" for each project are below. I hope they may be useful to anyone who wants to get into a similar project, to glean ideas for how something might be done, as well as things that might have been tried, or just thought of and not tried... and even of how not to do something - why it didn't work or proved impractical. Sometimes they set out inventive thoughts almost as they occur - and are the actual organization and elaboration in writing of those thoughts. They are thus partly a diary and are not extensively proof-read for literary perfection, consistency, completeness and elimination of duplications before publication. I hope they may add to the body of wisdom for other researchers and developers to help them find more productive paths and avoid potential pitfalls and dead ends.

Magnetic Variable Torque Converter

[21st] I finally stepped aside from the cabin walls for a bit and went to balance my lop-sided cast copper rotor, by bolting a weight onto it. I was thinking of a jig to get it to roll, but discovered that (lengthwise) it balanced perfectly on the edge of a table sitting on the steady bearing. Of course the bearing made it turn easily to where the lightest side was up. I drilled a hole there. And I put steel weights on top of the rim to estimate how much was needed. When heavy enough they caused the rotor to turn until they fell off.

   The back face of the copper could be rough as can be, but I decided the magnet-facing face just wouldn't do. I started grinding off the high spots and areas. After some dubious attempts using a ruler to figure out where these were, I found a brake disk of the same diameter on which I could set the rotor and (with a flashlight) see the places holding the rest up. Pushing down in different places around the edge I could find the highest spots where it 'hinged' and tipped up. Most of my lengthy grinding session was concentrated on the same two areas, and finally most of it - at least at the outer edge - was within 1/16th of on inch or so of the surface of the brake disk. It is by no means perfect, but more copper will be notably closer to the magnet rotor than it was. Hopefully the slip will be under 78 RPM.

   Of course the grinding changed not only the amount of imbalance but the position. But I had drilled and tapped just one hole so far. I found that if I simply turned the weight diagonal a bit it could still balance. And there was a 7/16" threaded hole in the inner end. If I screwed a small bolt into it the weight just about balanced the rotor.

  (Not much left to do, but I went back to working on the cabin while the weather was nice.)

[30th] I found the best balanced twist of the weight, then drilled and tapped a hole through the rotor and weight at its other end. It seemed quite close. The rotor would stop at any point, tho it had a very slight tendency to drift more toward a particular position if given slight momentum toward it. Considering the big difference any tiny change in weight made, I was quite pleased.

   I used flathead screws - they couldn't stick out on the magnet face.

[Sept. 5th] I noticed that the steel weight caused a certain amount of magnetic cogging. That might be interesting if the truck got up to speed and torque where the rotors would lock together. But it probably wasn't enough cogging force to be very effective. Two or three or four such steel blocks spaced around the copper rotor in line with the magnets might be reasonably effective.

   I installed it and started it up. There was still a lot of vibration - nothing like before, but still too much to consider driving the truck out of the garage. I got a video camera and clamped it on to see what the mechanism was doing, then drove ahead a bit and then back. The planetary gear and rear drive shaft coming from it were shimmying around as they turned, even very slowly, or even as the planetary turned with the truck stopped. I watched the video several times and finally realized that it must be the steel balancing weight. That side of the copper rotor was pulling the magnet rotor toward itself, and there was enough play in the gear body that it 'bent' toward the copper rotor on one side.
   So it went from mass imbalance to magnetic imbalance. I'll have to replace the steel weight with a copper one. The delays and setbacks on this seemingly simple project - improving the magnetic coupling of the torque converter - have been fierce!

Cabin Construction

Wait, what? Evidently I didn't write any detailed text for most of August's construction work, until the 28th when I finished the last footing. But the photos tell the tale...

[25th, 27th, 28th] I dug a trench for the final wall footing, lost a day, set up concrete forms and put rocks inside on the bottom to take up space during an afternoon, and then spent a day mixing and casting cement. Somehow the forms ended up a little wider and deeper than the last set and in spite of thinking I had extra sand, I used every bit of it, and had just a small block of cement left over from the last half pail. I also used the rest of the bag of cement and for the last couple of loads I used some half powder, half chunks - the remnants of a bag sitting under the travel trailer for two years since I did the south wall. (Hmm... the resulting footing seemed rather crumbly!)
  Finally it was done, but I was left hoping that I hadn't done more injury to my again painful "tennis" elbow with all that shoveling, toting and lifting of heavy pails of sand and just generally a long day of heavy work. I haven't dared try to split firewood this whole summer. I cut up and split a couple of alder trees in April before the injury and later bought some more already split. I hope that's enough wood for the winter. (It was finally getting - somewhat - better going into September.)

Foto sequence for the month's cabin work:

First a neighbor towed the Cougar travel trailer into a nice spot I had prepared [4th]

...leaving the cabin vacant for the first time ever!
I had framed wall section #6 on the 2nd.

I got the plywood up [11th]
(Corners of all the sheets got water damage and mold when stored under the sheet metal wall siding
in a pile. A piece of metal moved and left a rain gap I didn't notice. I'm using them whole anyway.)

...and quickly covered it with tyvec in the rain [12th]

Then I started putting up the alume siding.
As this siding was covering my lumber stacks, with each piece
I had to move another stack of lumber into the cabin. [19th]
(And they each needed thorough cleaning and the disintegrating anti-scratch
tape along the high edge of each piece had to be peeled off bit by bit.)

Growing stack of boards and some fiberglass insulation (yuk) for the ceiling
that I bought from someone who was moving, for under 1/2 the new price.

A notable cutting mistake at the window by the south door (in 2021) stabbed my eyes every time I looked at it.
But I wanted to be sure there were enough pieces of siding to replace it,
since it was evident by then that the number of sheets would be very close.

When it was clear there were enough pieces, one day I turned aside from doing the new wall
and fixed the old. But I cut it wrong again! (had panel upside down), and had to do it twice.

All told I just managed about one panel a day average on the new wall [23rd]

I finished the window end on the 24th: three walls at last done! - with one piece of siding to spare.
(It would have been three to spare if not for three bad cuts.
Ends of two of the bad ones were usable at this window, saving one. And I would have
had enough for the whole fourth wall if I hadn't used 16x20 feet worth on the carport roof in fall 2020.)

I poured the last section of footing [29th] Yay!
(Drain to an old septic tank runs through it.
That corner will be the bathroom.)

The previous section had taken about 4-1/2 pails of sand.
I filled 6 to be sure and expected leftovers, but this footing
was a bit deeper and wider and took all of it!

August Gardening

   I tried to grow corn and squash but they didn't fare well. The corn never grew well or got very tall. If summer lasted another month the squash might produce, but it's not warm enough now. The place I dug up in the lawn for them gets more shade than I thought. I'm going to let that plot go back to lawn and extend the house south wall garden where it's sunniest and warmest.

Again here's the tale in pictures.

[Aug. 5th] There was a big difference between the sunflowers planted late...

...and those three potted in early April that survived the slugs when transplanted.

I also grew some quinoa. I'm not sure it's going to ripen.
Caterpillars ate the leaves to skeletons.

[Aug. 11th] The chickens had six surviving chicks. Apparently they are all camera shy.
The hens sat on eggs a long time and made no new eggs all summer.
Finally by month's end there are more.

A deer came through my unfastened chicken wire at the outer door of the greenhouse.
The grape leaves it ate exposed a little cluster of very small grapes.
(I thought I saw a few flowers on it in the spring!)
By watering daily finally things are starting to flourish. It's taken me far, far too long to learn that
gardens, fruit trees and especially greenhouses, need more than just a couple of waterings a week!

It also ate all but 8 live leaves off the cherry tree I dug out of the rocks in
town and so carefully water 2 or 3 times a day because it has so few roots.
Now I hope it makes it through the winter, is growing more roots, and
isn't dead except for the couple of branches that still have leaves. I belatedly
stapled the chicken wire in place over the open door to block the marauding deers.

[29th] Here again the later planted sunflowers don't look like they'll get ripe
and form seeds before it's too cold. Few pollinators are coming to the flowers.
The cardboard is to kill the grass where I'm expanding the garden next year.

The three earliest sunflowers are ready to harvest and I got huge heads of great seeds off them.
Gotta guard them better from the slugs next year!

This later one is shooting for the moon and is
now [Sept. 8th] 9 feet tall. And finally the
flower is opening, probably much too late.

[31st] South side of main garden looking West.
There's some good produce but it's obvious I planted all
the little seeds and seedlings much too close together.

And looking East. Behind the peas (which didn't do well - a deer got in one night and ate many
young plants) I've dug up around 15 Kg of beautiful red potatos. Mostly I transplanted whatever
potatos I found growing as I prepared the beds and I was surprised by all these like ones. IIRC
somebody gave me a bag of sprouting potatos this spring. I'll have to give them a bag of the results!

Onions were small - they did much better in the house south wall garden, and the carrots were
very small because of being planted late. Some beans are flowering or have small beans in
September - again they were planted rather late. But the weather is crappy earlier and it took
that long to get all the beds ready and plant them all. Hopefully next spring will be easier.

The Usual Daily/Monthly/Yearly Log of Solar Power Generated [and grid power consumed]

(All times are in PST: clock 48 minutes ahead of local sun time, not PDT which is an hour and 48 minutes ahead. (DC) battery system power output readings are reset to zero daily (often just for LED lights, occasionally used with other loads: Chevy Sprint electric car, inverters in power outages or other 36V loads), while the grid tied readings are cumulative.)

Daily Figures

Notes: House Main meter (6 digits) accumulates. DC meter now accumulates until [before] it loses precision (9.999 WH => 0010 KWH), then is reset. House East and Cabin meters (4 digits) are reset to 0 when they get near 99.99 (which goes to "100.0") - owing to loss of second decimal precision.

2. 248.38$ ; 1034.91$ ; 2069.82$

4. 455.20$ ; 1896.69$ ; 3793.37$

   It can be seen that the benefit to the society as a whole on Haida Gwaii from solar power installations is much greater than the cost savings to the individual user of electricity, thanks to the heavy subsidization of our power owing to the BC government policy of having the same power rate across the entire province regardless of the cost of production. And it can be insurance: With some extra equipment and a battery, sufficient solar can deliver essential power in electrical outages however long. (Feb 28th 2023: And it's probably well over 1$/KWH by now the way inflation of diesel fuel and other costs is running.)
