Navy Patent to modify Mass / Inertia

Patent for a craft using an Inertial Mass Reduction Device   patent number 10,144,532B2

It was brought to my attention that a researcher for the U.S. Navy had patented a device for the reduction of mass / inertia,  last December, on work he has been doing  for the last 12 years.  There are many citations of papers of his own as well as work done by others,

After reading the patent claims it appears to me that this is a proposed device patent meant to cover the possibilities rather then an actual device. The author seems to use a great deal of techno-babble to dance around,  Not saying Aether,  to describe the EMF manipulation of the near to the craft, space, to reduce the effects of Mass / Inertia by creating a richly confused, 3 Dimensional field…pg

We want to put these units out on long term loan to those that donate to our R&D effort, please indicate any interest in this comment thread below…pg

Airwasher

7inch x 12.5inch x 12inch high – 175 x 320mm x 300mm high T6c-Airwasher

The project of the last 2 years  is completed and several of these miniature industrial Airwashers are now being used by my family members. They are testing it’s operation under real conditions of cleaning the air in their homes and to offer their critique on it.

The funnel to the left of the scrubber power  head is for an upended 2 liter soda pop bottle to supply additional makeup water as it evaporates and to maintain the proper operating water level within the machine. see below.

T6c Airwasher

With the supply bottle in operation the machine draws 58 watts of power as it cleans about 60 cubic feet of air a minute, while trapping the pollutants in the 4 liters of water in the clear acrylic plastic tank  bellow it.

With the exception of the water tank and the 2 Liter “pop” bottle, all of the plastic parts were created out of about 1 kilogram 2+ pounds of ABS plastic on a small Desktop 3D Printer from files created with a desktop computer. Truly a manufacturing empire on my kitchen table! …pg

The New Old Project – multiplication

The song of the little Robot is silent for the moment as I consider my kitchen table of little fume scrubbers and contemplate, my NEXT number.

A multiplicity of scrubbers

A multiplicity of scrubbers

The Black Airwasher on the left has been working for me for a couple of weeks as We , the robot and I, create new additions to it’s family. The Blue and Whites are nearly ready to go out into the world. All spiffy in their livery and labels. They just need motors and containment tubs to be completed.  There is a also a box, a Large Box, full of scrap and failures to show for my learning experience along the way. I am pleased with both the appearance and function of these tiny industrial fume scrubbing machines.

( man I have got to get a better camera or learn how to better use this one)

As this is an R & D effort, completed Blue and Whites will be sent out on permanent loan to those that donate $250 to my effort, so that they can evaluate, under real world conditions,  and offer their wisdom for needed improvements.  And I can continue to buy coffee for me and filament & electricity for the robot.

Next is to design and create a better water management system and base to replace that food container. This thing is getting too big for the little printer’s build bed. I must section and then glue up this next addition that will make the Airwasher more user friendly. Adding 16 oz. of water every 4 hours is a necessary thing,  but an annoyance. A 2 liter water supply bottle or even two of them would make servicing only a daily chore. The hand made ones of 25 years ago had this feature and it was planned on in the consumer model, but this little printer was just too small for the needed build footprint…pg

My adventure in 3D printing

monoprice iiip

Monoprice 3D Printer IIIPv2

This Little 3D printer is about the minimum usable, as well as inexpensive, machine available.  Amazon.com/monoprice   $250 at this date.

2 years ago I purchased this little machine, with it’s 200mm x 200mm ( 7.8″ x 7.8″) build plate, so my grandson could get acquainted with this new technology along with his computer abilities. Last fall with the nearby Camp Fire and attendant bad air quality, I was reminded of the need for my  water based air cleaners. I REALLY needed to get new ones built! even if just for me and other family members. So I set the printer up next to my computer and began the design. see: A new old project & The new old project continues. My sister prevailed on me to help launch this new business, it became important to share what I have learned, so she and her son could become familiar with the technology without starting from total ignorance..pg

The question of the cost to be a part of using 3D printing was posed and after some thought I replied; “ I am amazed at how little I have spent for the things that this little IIIPv2 printer, Optiplex780 computer and I have accomplished over the last 3 months. For less then a thousand dollars we have created things that would cost me tens of thousands and 2 years, 25 years ago. The 21st century is an Amazing place to this 20th century man…pg

 

An excellent pdf on filament printing for a beginner starting out…pg

Back in 1986 I took a temporary job fabricating equipment for the Silicon Valley electronics industry. Equipment such as tanks, containment trays, fume duct work and fume scrubbers created from shaped plastic sheet stock parts Hot air welded together with a hot air welder and plastic rod.  Plastic welding requires that the material be heated to the point that it will flow and stick, but not yet a fluid as one uses in metal welding. Plastic is made up of long chain hydrocarbons much like spaghetti that must be heated to the point that it is much like wet cooked pasta that will flow and stick but not break up or have it’s structure destroyed, a rather fine line of temperature that is particular to that type of plastic or alloy of plastics. 3D printing of plastic filaments is carried out under much the same conditions. In this case a miniature extruder under the control of a computer directed robot is laying down “welding rod” to create an object.

The job of the operator is to evaluate the conditions, manage the heat energy and material applied, to create the conditions for a good weld buildup of the part.

Due to the nature of the device being used the building part must remain solidly in place on the build bed during it’s creation. Much of the problems encountered in 3D printing center around keeping the building part in stuck in place. Then, at the end of the build the part should be easily removed so that the bed alignment is not disturbed, the bed surface is not damaged or warped, and the next part can be started.

 

Printer Notes:

New printer setup:

First thing, check all fasteners for tightness, Modestly tight, not finger tight, not OMG tight, but well fastened. All attachments must remain stable. The software assumes a stable machine and the printer does not self correct for any displacement during operation.

Set printer on a resilient bed such as ridged foam, hard rubber foam, etc. This will greatly reduce noise transfer and reduce resonant movements as the build bed and the mass of the printed object is rapidly moved under the Extruder head. Tie down the “Z” towers solid to frame, with angle braces or attachments to enclosure frame. The towers MUST be stable to the frame, there must be no chance of induced wobble during print bed movements. Any wobble can result in the nozzle encountering the solid work piece, causing a displacement that will ruin the work and may damage the printer.

We will be using ABS so heat management is critical for best results. The operating printer bed must be in a very warm, draft free environment, so an enclosure of some kind is important for consistent results. Being able to see the results of the printer’s operations as they happen is valuable, so the operator can observe, make any adjustments needed is very useful, so a “window” should be considered.

Periodic service before printing:

To insure that the part remains “stuck” to the print bed during it’s creation is critical to success. Be sure to clean bed covering of all dust and oils. Isopropal Alcohol works best, Acetone will work but will damage PEI coverings. Or add a glass covering, glass will require additional time to heat up ( 15-20min.), any glass will work and is less likely to be damaged by use, thicker glass will be less likely to warp, but glass will need additional fasteners to prevent movement on the bed table. Glass adds to the mass of the bed that will be in motion as well as it requires changes in the bottom limit switch position due to it’s additional thickness. We are using a Borosilicate glass covering as that has the best”stick” while hot and best release when cooled. Do not touch the bed covering after cleaning. To improve “stick” of the part to the build bed, various materials are often used to act as temporary “glue”. We are using ABS dissolved in Acetone as our sticking agent for most parts and sometimes Painters tape for really difficult to stick, critical large parts. The Painters Tape is the last resort as it is difficult to remove after the completion of the print. Also used by others are Hair Spray, paper glue stick, as well as salt and sugar. All water based that will stick hot and pop lose on cooling. many people print small and light pieces with no glue and others use special build plate coverings that seem to work with no additional adhesion.  When printing with ABS it is critical that the piece remain warm and well adhered to the build bed during the build process. Any draft that might cool the bed, part or Extruder can ruin the work as well as the “stick”to the bed. Temperature MANAGEMENT is critical while working with ABS!

It is critical to adjust the machinery to be properly aligned, the Extruder must move parallel to the bed to lay even layers onto the surface of the build. In our type of printer the part creation bed moves back and forth in the “Y” plain under the Extruder. The Extruder moves in the side to side motion of the “X” plain and is supported by it’s carriage that is moved in the “Z” direction up to lay down the layers. In our case the Extruder carriage  is controlled by two stepper motors that sometimes get out of synchronization, measure the distance of the carriage rods over the bed to be sure they are parallel to the bed. If not, they can easily be rotated into alignment while the printer is off. While energized they are electrically locked together.

To “level” or trammel the bed to printer nozzle there are adjusting thumb wheels or nuts in each corner of the bed. These are adjusted corner to corner, at least 3 times around. As you adjust one corner the diagonally opposite one will change as the bed teeters on the other two corners. Typewriter paper works well as a thickness gauge. Nozzle should just barely “grip” the paper to the bed. This must be completed on a “Hot” bed to be true for heated operation. It is very important that the first layer be properly stuck to the bed. We use “brim” as an attachment enhancement, as it adds no additional height to the parts, something that is critical to maintain measurements when several parts are assembled together. Once the printer begins the “Brim” the first deposition from the Extruder can be examined for good attachment to the build plate as well as the proper “squish”width and thickness.
It is at this time that I do final adjustment of the bed.

There are also now add-ons that will test the bed surface distances and read into the Gcode the needed nozzle position to properly stick that first layer.

After the print is completed and the print bed cools I slide a sharp thin blade under it to help release it from the bed. The more gently you can remove the part the better to prevent warpage or displacement of the bed adjustments.

Sharp thin blade tool:

I took a good quality, flexible putty knife and ground one side into a wood chisel like sharp edge. To assist lifting the part or for scraping the build plate I use it bevel side up to get under the brim and part to begin lifting them. Caution! Do not use this on a warm soft build plate cover material such as PEI, it will cut right through them, use only on glass or other hard materials.

Software We are using:

Acad 17 is being used to model the parts and export them as stl ‘s. There is also 360 Fusion available to private users as well as several free 3D modeling programs. These stl’s are actually cross-sections of the parts that are being exported into the Slicer that reads these files and then computes the needed instructions that the printer carries out. Printers are dumb, they are a very simple computer that only handle specific movements and temperature. Slicers convert the object into step-by-step directions for the printer to follow. Things like, maintain temperature, start extruding, move x-axis 10 mm and y-axis 2mm, and so on. Most of those commands start with a G, hence the name Gcode. A slicer translates the model slices into the needed movements, speeds and temperatures that are set in configuration instructions which the printer understands.

“Repetier-Host”, A freeware program, is being used to import the stl files and manage the “slicer” that creates the Gcode files and serves those instructions to the printer. Cura, A freeware program, is a slicer that is used to create the needed Gcode files that instruct the printer on how to execute the creation of the required piece. These Gcode files are the instructions that operate the “printer” to build the object one layer at a time by depositing material in amounts and position as dictated by the results of information developed by the “Slicer” program . The needed Gcode is specific to the printer being used and the slicer instructions are set in configuration before the slicer is engaged. The Gcode files are served to the printer through WiFi, or a USB connection or via. a SD card by Repetier-Host the server program that the “slicer” it is embedded in.

Problems,

Early problem was prints were so porous that water would readily go through the walls but the tops and bottoms were quite solid. Found that tops & bottoms set were default set at 3x and the walls at 1x. I reset the tops & bottoms to 2x as well as set the walls to 2x. This increased the time required and material used but resulted in a substantial improvement in part quality.

increased the extrusion rate 10% to get a stronger more solid part and the result was…

As I was attempting to print the third of 3 motor bases, again I hear this pop and the printer dislocates the “X” axis at about the 1.1 inch line, What the heck! This was 3 times in a row at about the same point, damaging the print. now I will have to section off the top quarter of an inch of the model and print 3 of those and repair all 3 motor bases. But why ?  I sleep on this problem and…  of course! the extrusion is too high. We have been making the layers just a bit too thick and after an inch of layers the build was too high and during a travel move from side to side the no longer high enough nozzle impacted the build so hard that the “X” belt jumped the sprocket and the machine lost it’s registry of position, always at about the same spot.  Reduced the extrusion rate, end of that problem.

notes from 3D Printing:

Pg Sharrow One of the things I learned during years of plastic welding is that every formulation of plastic and COLOR behaves differently. White is different from Black. Blue or Red. Every time you change supplier or color you must change your technique.
Rob Smith I would print a temp tower… Believe it or not, every spool has its own ideal temperature, even if it’s the same material in the same color from the same manufacturer. Cura has a plugin called “ChangeAtZ” that makes it easy to change the temperature at specific layers, and there are dozens of models on Thingiverse to choose from. A good temp tower will have features that highlight bridging quality, overhangs, stringing control, and of course, surface finish. I like this one:

Rob Smith No problem! Protip: the temp tower is a great diagnostic tool, but it’s not the only one. There are a bunch of prints that are popular for “benchmarking” your printer’s performance… Lately Benchy has been the most popular (https://www.thingiverse.com/thing:763622) and before that it was Marvin (https://www.thingiverse.com/thing:215703)… but if you’re really looking to fine-tune your printer, there’s a collection of carefully-chosen calibration prints to challenge your sanity: https://www.thingiverse.com/thing:533472
If you have the chutzpah to try printing all of them a) remember each one is a unique purpose-built test, and it’s designed to be challenging, and b) post pictures!

 for setup of the IIIPv2 in Curia

Aaron Greengrass Printers are different enough from each other that there are no ‘standard’ settings. My hotend has had 4 different layer cooling fans. Each one requires a number of changes to print settings to get a good print. Of the 9 printers I’ve owned so far, only 2 have even been vaguely similar, and even they didn’t have identical settings. Test, adjust, and test again. Print slower. Watch a lot of youtube videos about dialing in printer settings. Look at the print troubleshooting pages (the one simplify3d has is pretty good). Expect this to require trial and error. Expect also that whatever settings you get working will require changes not only for different types of filament, but in many cases for different colors (ie translucent vs solid color print very differently)

Todd Saltzman The way you have to approach it is when your print comes out bad you need to identify what exactly is bad about it. Such as is it over extruding or being too stringy etc. then you need to look at the solutions to your problem and just adjust small things at a time.
advise and links I greatly appreciate…pg

A New Old Project

The Genii Whirlwind Airwasher

While blogging in the dark of smoke and power outage of the Camp Fire. I struck up conversation through an Internet Link with my youngest sister about my need for one of my fume scrubbers. The last of the hand made ones died last year. My grandson and I had purchased a small 3D printer last year to begin creating a new model. Something some of us need from time to time to breath and sleep during periods of poor air quality. My sister , a recently retired educator was interested in helping her brother in creating a business to manufacture and market this consumer market Airwasher that I had developed over 25 years ago and had failed to successfully bring to market.

old airwashers

People that used the hand made units really loved them, including myself but the unknown changes in motor quality by the motor manufacture right after I started creating them doomed that effort and often caused premature failure of the devices. An economic down turn at a critical time caused my prospective investors to backout and the effort collapsed.  The Proposed consumer model was abandoned. Oh well, I moved on.

With the Internet and 3D printers we might be able get this going for something less then the $500,000 that I was looking at the last time and if my sister and her adult son take an interest they might be able to create a real business for themselves and I can continue my other projects. Finance and business management are among her talents and her son is an independent craftsman/tradesman type. This might even work out and I won’t have to do everything myself like the last time.     Ok ! lets go for it!

Once again I am digging into Acad and creating files to be printed for test models that can evolve into Beta units that will result in injection molded retail consumer units.

Quality, Swamp cooler water pumps are providing the motors for the new effort and the possibility of designing around the right kind of motors for the job. I need to set up a printer cabinet in my cozy computer Lab.  😉 Lol while doing test work in the kitchen. Getting the water pickup, air flow and effective scrub action while making efficient use of the motor without overloading it will be the next challenge.  Every part must be laid out so it can be created by the printer, no small thing. This requires 3 dimensional visualization and planning. Luckily with Acad, the computer can Show me the proposed part  before I print my mistakes.  Next learn about how to operate a 3D printer to print this 4 part power head that is the motor enclosure, water pickup and scrub blower.

1 airwasher

Wow! that is close to actual size on my monitor, 5 inch blower ring and 6 inch motor mount disk. While I’m resting I will need to figure out the scrubbing scroll and air guides …pg

Airwasher02

December 9  I just got the Acad file done on the above, looks good enough to print. All of the internal parts are laid out. Now to set up the printer and figure out how it works. Take these Drawings apart and rasterize the individual parts for the printer to render into plastic. The AirWasher box is 7 inches square, as large as the little 3D printer can make, I would prefer 10 inches for better scrub action. I may attempt a glueup for later testing or we may set up a larger printer later.

Then I can test to see if 25 year old memories are still valid. Only took 2 weeks to get fairly comfortable in Acad again. It certainly renders nice visuals, Almost as good as a real picture….pg

January 2 2019 update……you can see the improvement in my CAD abilities as well as the design improvements in the proposed Airwasher as well as my grasp of 3D printer use.

Airwasher T6 blowup

T6 Genii Whirlwind Airwasher

The white container is an off the shelf, semi-clear poly, 1 gallon food container. The motor is from a quality swamp cooler water pump. The rest of the scrubber parts are all printed on a small 200mm x 200mm deck printer. The real device is not quite as colorful as we only have one color of filament, but HR remarked about how color coding being a real help in CAD work. While peering into a complex 3D CAD file can be very confusing, the contrasting colors are a big help, as is the ability to move from wireform drawings to realistic renderings as needed, this is a wonderful improvement in doing CAD work.

As you can see the power head and scrub sections lift out of the bucket for ease in daily cleaning. No screens, no filters, no added chemicals, just water and 60 watts of power to really clean the air in a large, 300 square foot room. Dust, pollen, chemical vapors, nearly anything that can harm you can be removed with this Industrial fume scrubber. Wow! I have impressed myself this time.

January 8 2019  I now have a test unit running for 2 days. So nice to have an Airwasher running in my space again. Dust levels inside already are decreasing and smell is freshened. Needs improvements, but at least it works. My Lady, my sister, my daughter, all want a copy of their own. Still having problems mastering the printer to get dependable results. Seems to require some spell or secret knowledge. Maybe a bigger better printer would solve my problems?  Maybe, someday,……..pg

The Camp Fire

The great campfire of 2018

I sit at my computer in the near dark as we finish the forth day of this adventure. No electrical service, so running on battery UPS that is chirping at me. I will need to start the generator again. Only a few gallons of gas left. Fuel smuggled to me by a local friend that knows the back ways. The Officials have us under blockade so we can’t go for food or fuel. The fire is several miles to the south of us.

In the middle top of the map below is a full 90 degree crossroad.  I am at the lower end of the left or west branch of it, just above the forks of the stream there. About 2 mile below the Forest Ranch caption. Fire is now very subdued burning over grass and light brush. The red and orange spots are the active fires at this pictures date 11-11-2018 7:30am.

campfire

screen shot 11-11-2018 7:30am

I got up at daylight Thursday.  About 6:30 and there was a light red smudge on the horizon to the south east, by 8:00 the power was cut off. After a couple of hours that smudge had grown into an angry towering black cloud the soon filled  the south horizon all the way to Chico, and the booming of exploding of LP tanks soon followed. A North to South air flow kept the cloud at bay but it towered higher and higher as the fire progressed in our direction. The wind from the north strikes a tall ridge to our south and the resulting Up Draft creates a from the south surface draft as a back flow over Paradise/Megalia. Perfect air flow conditions to suck a fire from Pulga up the rolling hills into town through very dry grass, brush, and pine.  The air spillage to the west from that ridge also funneled air to the west  sucking smoke and fire into Chico. After a time of watching this unfolding disaster We dig out the generator that hasn’t been used in 16 years. Clean out the fuel tank and and add gasoline. Set the choke, third pull it Starts ! Wow! I didn’t expect it to be that easy to get the thing running. As we only have 5 gallons of fuel on hand for the generators, we must husband our use. It is nearing dark and we have No Idea how long this will last…pg

A personal note:

Something that has been rattling around in my brain.
In 1961 at this time of the year my family’s home burned to the ground and we were left with nothing but the cloths we were wearing. I was just 15, …………………………………………..It
was a long cold winter..pg

Friday morning, the southern horizon sky is a bit murky but the smoke billowing from the fires are much reduced, My guess is the worst is over but it will be at least a week before it is well suppressed. We can’t go for fuel or supplies because of government edict. Electric power was cut off yesterday morning. No big thing, just do without. This is a fairly safe place. It is too bad that the Ecoloons prevented good fuels management and turned the Paradise/Magalia area into a explosive fire area. Nature has fixed that problem for now…pg

Saturday, Because of the blockade we have to organize a smuggling operation to get fuel in. A friend uses a jeep trail to bring in fuel for my neighbor and I, while he picks up things to store in his root cellar or take down to Chico for safe keeping. We can leave the area but would be blocked from returning. This sucks, we are staying. My neighbor and I are well versed on fire dangers, have evaluated the situation and know that we and our properties are quite safe. The fire is over 105,000 acres in size with 5% containment. We now have 8 gallons of gas for the generators, maybe 2 days worth, to keep the refers cold, some lights and me on the internet, phone line has been dead since morning and no cell phone service…pg

This is Sunday, the fire has not grown appreciably today, 109,000 acres in size. 25% contained  at least 29 dead, 6500 homes destroyed and nearly 60,000 people displaced. Poor management of biomass fuels has created this great disaster one of many in California. I still don’t see any signs of intelligence in the political class of “leaders”. Just a bunch of touche-feelies and the out going Governor calling for 100s of billions of dollars to fight “Global Warning” and the new one seems worse,

As the sun sets this evening, there is a light smudge of red in the air to the west from the small fires burning below…pg

Monday, connections are being made to deliver fuel and food to us. It is a smoky day as the North wind has subsided and there are still a few grass fires several miles down the canyon from us, mainly back fires to rid the area of fuel under controlled conditions.  After the car arrives I set to using the car fuel pump in the tank to pump 20 gallons of gasoline into the empty containers. Wonderful! We now have fuel for the coming week. The refers can be kept cold and water pumped as needed…pg

A bit after 7pm Electrical service is restored to us. HURRAH ! I can shut down the generators.  I have real lights to type under and may even get to take a warm shower before bed. Life is slowly beginning to return to normal….pg

Tuesday morning, it is a bit smokey, things are returning to normal conditions, for us. We are out of danger here.  But for others this hell will continue.  Fire is 30% contained at 125,000 acres. 43 fatalities confirmed – more to find I’m sure. 200 people are still missing.  Homes destroyed nearing 7 thousand, as well as hundreds of business operations wiped out. 50 thousand people or more are are more or less homeless and the first rains are a week away….pg

Wednesday; the air is smokey and calm, very boring day here, that is good, just putting things away. The reports are 56 fatalities known, 146 still missing, nearly 9,000 homes destroyed, 52,000 people displaced by the fire and official actions. 138,000 acres involved and the fire 35% contained.

A possible humanitarian disaster is approaching in the form of a cold wet northern storm that should strike in a week with many thousands of people living in their cars or in the streets and parking lots with little real shelter, because the Officials don’t want them to go back to their homes in and around the fire area, nearly 2/3 of those displaced have intact homes to go back to but at present are locked out of the area. …pg

Thursday, Now that my situation has stabilized I can point out the cause of this Camp Fire disaster. While poor fuels management caused by the Ecoloons of the area, specially those in the local government was a major factor. The fire storm that swept through Paradise/Magalia was caused by a rare fluke of geography and weather.
To the south of me and to the north of Paradise/Magalia is a tall ridge that looms over the rolling hills that the town sprawl covers in a mature Pine forest. This DoeMill Ridge was in direct line to block and lift the North Wind that blew against it. causing an up draft that sucked air from the South where the fire started toward the north over the city. between that city and the ridge is a deep canyon that funneled the return flow to the west towards Chico over the only hiway leading down out of the area. A Fire Storm swept south to north and then east to west over the people fleeing the area in their normal directions on the normal way of getting into and out of the area.
Now that the fire has traveled to the west and out of the shadow of the ridge the north wind is pushing the fire towards the south and Oroville…pg

Friday dawns smokey, visibility is nearly a mile, The blockade on us was lifted last evening, we can now come and go to town for supplies. Most of the area is still in lock down and the first winter storm approaches, late Tuesday night to begin at least a week of wet cold weather. 2 inches of near freezing rain on it’s way and the forecast has been getting wetter and colder as the storms get closer. Motel rents are now over $1,000 per week. People with intact houses are living in their cars or tents all over the area outside the fire zone. Lucky ones are staying with friends or family as this disaster continues…pg

Saturday is smoky, almost 1 mile visibility. some people being allowed to return to their homes. The President has made his appearance and left. 149,000 acres burned, 55% containment, over 9,000 dwellings burned, 76 fatalities known, over 1,200 still missing, 46,000 still evacuated ….pg

It is now Wednesday morning,  the wet has arrived with a damp drizzle and fire fighting will begin to change from fire suppression to cleanup. As much as 6 inches of rain forecast for the burn area in the next 3 days. Air is clearing as wind and water does it’s magic in restoring the Atmosphere.  79 fatalities known and over 400 still missing. Over 40,000 still evacuated and over 9,000 homes destroyed. For some this disaster continues…pg

Wednesday evening the power goes down again, off all night long, well this sucks, we were expecting to cook the Thanksgiving Turkey in our electric stove. My sister recommends the big BBQ to roast the Turkey, why not! I set it up, start the thing heating and ready the bird, breast down Garlic Olive Oil slathered all over,  put in the Turkey at 8 am, after an hour the power comes back on and We transfer the turkey to the 325F oven, at noon, the 17 pound bird is cooked to perfection, 4 hours total time. Sometimes you get lucky!

November 23, the day after Thanksgiving. After 2 days of heavy rain the fire is nearly out. 153,334 acres burned, 95% contained. 84 known fatalities and 475 still missing. over 10,000 homes and businesses burned out. and nearly 40,000 still homeless….pg

Saturday, November 24 , We went into FEMA’s temporary facility in Chico to register as being in the Camp Fire effected area. Considering the expected zoo they were well organized, most helpful and fast. They claimed to have processed over 5,000 people in 3 days, I can believe it. It was crowded, They were using a closed Sears super store for a facility and the shopping center parking lot was FULL. The registration was necessary for any long term, to be determined later,  assistance. Agencies such as CalFire also made immediate funding and assistance available to those in real need. CalFire -$250 to those that registered. Not much, but still something to those with little more then their hands in their pockets. Nearly $2 million into the local economy. Many other agencies involved within the same place, for after registration help. All things considered, I would give them all high marks for their attempts to create some order out of the expected chaos. I would guess FEMA has learned a few things about dealing with the aftermath of disasters…pg

the Word

The Word was GOD

In the beginning Humans were as “Beasts of the Field” Without language or history. The ape like “see do” and personal experience were the only means to learn new things and non-language vocalization and gestures the only way to communicate. Then came the invention of “WORD”,   The naming of things, events, conditions, motions, places, the communication of experiences and knowledge, one brain to the next. “And the Word was GOD”, the properly naming of something gave power over it. MAGIC!

The old could teach the young their knowledge, describe their experiences, their wisdom. The total of Human knowledge could multiply far beyond the ability of one person to gather through experience.

For thousands of years knowledge was memorized one generation to the next, but that required person to person exchange. Persons rarely traveled much in distance nor communicated with many different people. Knowledge traveled slowly from one group to the next if at all. Knowledge became family or tribal limited by the use of local words and phrases.

It is said that King Nimrod sent his soldiers out to collect the wisemen of his kingdom into a university, an Ivory Tower of learning so that all the knowledge of the land could be exchanged and taught to the young.

As a memory tool, cypher or pictographs were created, In time these evolved into a common language that everyone schooled in their use could understand and use, regardless of their native dialect The transfer of knowledge no longer required a common language or person to person contact. A written language of common words evolved. The knowledge base expanded and spread, it even could be communicated over extended time.

Writing these words of wisdom required a long a laborious process so these books of knowledge were rare and expensive only the wealthy or connected could access them. In time, Hand copied pages became machine printed pages and books of a few copies became additions of thousands, then became copied in the millions. The spread of the “Word” knowledge, became available to everyone. But still a difficult and expensive process under the limiting control of the few.

Today we have this miracle of the electronic computer age of an inexpensive World Wide Web.  Communication of thought and knowledge in real time and translated into the language of your choice.

The wealthy and powerful still struggle to impose and maintain their control over knowledge.

A real Rodeo

Image may contain: sky, outdoor and nature

Desert Rodeo

Back in “85” I was entertaining my friends at the Golden’s bar in Cederville and Tom Espil shows up, wants to take me out to the lower Solder Creek Ranch to get a walkin cooler going.

In the early 1960s I went to high school with the Espil boys in Cederville, California, a small cow town near the Oregon/Nevada corner of California. John was a classmate, Tom a couple years younger and Brent a few years younger.

So we gather up my gear and head out south on the Gerlach Rd to the ranch a hundred miles out into the desert. Got introduced at the ranch but Tommy had to go to Susanville, be back the next day. So I examine the job and got started, Brent and his giant dog have to work the local range cattle, without help, so he is very busy, but his wife Vicky is a good hostess and I get the job done by afternoon the next day…..but no Tommy.

Brent sets me to servicing the generator and then fix a couple of tractors, clean and organize the shop,  but, After 4 days still no Tommy and I’m running out of things to do.  Brent says they are doing a big roundup the next day and invites me to join as a rider. Ok, I can ride.

We get to the campsite before dark and set up for the night along with the rest of the crew. Before light we roust up and wake up the remuda, the horses no happier in the dark cold morning then the rest of us. I get assigned a horse and gear, Saddle him up, draw up the cinch but leave it unbound as I walk around, talk to the horse, check the gear, drink the last of the coffee, get instructions. Day light comes, time to get to work. Walk back to the horse, draw up the cinch strap tight and bind it up. Now when you first saddle up a horse they will swell up and after they relax you wind up with a loose saddle and real problems if the horse moves abruptly. Hence the delay in binding up the cinch. UP into the saddle and we start out down the trail to the flat, my horse starts crow hopping and dancing around.I let him get a few good jumps in and come down hard with heels and the tails of the reins to force the horse into a run and now we run into a circle in the brush back to the posse. Guys were smiling at their entertainment, guess I, can ride.

As we enter the valley the riders spread out. Across the flat, maybe 25 riders from 5 outfits are gathering 600 pairs of cattle for brand marking and medication treatment of the young calves. As we work our way across the prairie gathering the cattle, Antelope bucks are gathering their harems of does with young and moving them behind us. Antelope hang out with the cattle because those big cows will help keep coyote away from attacking the tiny young kids . One buck passes near me with his 5 does, He has the tallest horns I have ever seen, near 30 inches! Wow ! The gathering herd is moved towards a natural arena in the rim-rock where the ground crew is setting up their equipment and fire pit to heat the Irons. The riders keep the herd milling within the “arena” while the real Cowboys begin working their way through the herd selecting the pairs that need attention. The head roper catches the calf and moves it toward the ground crew. As they near that crew the second roper catches it’s hind legs and pins it in place so the bulldoger can drop it and tie the legs. The ropers instruct the ground crew as to the outfit the calf belongs to as the bulldoger removes the ropes for the ropers so they can pick up the next pair. The smell and sounds of cow and horse, sagebrush , fire and sweat. A real Rodeo out in the desert as cowmen do their work. Is this fun or work?

As long as they can work from the back of a horse, Cowboys will work any hours under any conditions. Sometimes even pay for the privilege of working on a real ranch doing cowboy things chasing real cattle! I always thought a horse was a poor means of transportation. Very dangerous as well.  On the Espil Ranch, cowboy was the lowest level of employment. If you were good at that job you could advance to being a sheep herder. A job of greater responsibility and a lot less work under better conditions.

While we were working the cattle, The sheep operation was doing similar work in corrals further to north east tending to bands of Espil sheep

We are done before noon and head back to break camp and head out on a rough 8 mile track east through the rimrock to the upper ranch. There is a Bar-B-Que at the upper ranch!   The Espils know how to throw a party.  Beer and wine, Desert Oysters,  Barbecued Beast and a vast array of fixins…pg

Oh yes, Tommy shows up at the party, he is in a hurry to return to his place near Eagleville   😦  as well as take me home.   …pg

Physics discussion on Aether Propulsion

@Jim2:

It is looking like pervasive “fields” are all that is real, and “particles” are just what you get when something pokes the field. (So a photon hitting the “electron field” causes the “electron particle” to come into being and changes the “2 slot” outcome to the particle form… )

Basically, if we don’t look then everything is a field. It is when we look that it becomes particles…

Isn’t QM fun? 8-} /sarc;

“Basically, if we don’t look then everything is a field. It is when we look that it becomes particles…”
yup! pretty much sums it up. K.I.S.S. ! 😎 …pg

Maybe a lot of the problem with QM is that we can visualise waves OK, and we know about particles and how they collide, and neither the maths nor the visualisation work that well for something that is both at the same time. This isn’t helped by the Copenhagen interpretation, which tells us that it’s only when we look that the wave functions “collapse” into a single result from being indeterminate before we look. Given the age of the universe, and the lack of people to look and measure, it makes sense that things happen whether we look or not. That problem of only having a real result when someone measures it was got over with Bohmian Mechanics, where a “guiding wave” determines the position and direction of a real particle (which makes the wave and the particle there at the same time, and thus things can happen without anyone to measure them). However, this explanation wasn’t chosen, possibly because it effectively posits an Aether (the medium that the guiding wave exists in), and people were trying to go away from anything Aether-like. As I’ve said before, though, if you’re going to have waves of any sort, then as far as we can tell *something* will be waving, and a model with inertial minuscule particles with springs between them is bound to work for a lot of the properties. Basically, you can’t get away from some sort of Aether, even if you rename it as spacetime and say there can be waves in spacetime, unless of course you try to make a model where waves don’t exist and it’s only particles. Since a particle model isn’t going to match reality when it comes to diffraction unless you give the particles some wave properties, and again that implies something being waved, finding a non-paradoxical description has so far escaped us.

At the heart of QM we thus have paradox, which tells us we haven’t yet got a good description of what is actually happening. The models we’ve got mostly work pretty well despite the paradox, though, so it’s the best we’ve got at the moment and mostly we ignore the paradoxes and choose the description of particle or wave depending on which one gives the right answer. Another problem with current theory is that it has inconvenient infinities turning up in the maths. Where these turn up, the technique of “renormalisation” is used, which basically means we ignore the infinities and take them out of the equations, and the rest of the equation then gives the right answer. It’s a fudge, and wasn’t liked at the time it was introduced (can’t remember who by), but sorts the problem. http://www.volkerschatz.com/science/renorm.html . Wikipedia has a nice explanation, too, that goes quite a bit deeper.

One thing that bugs me about all this complex maths is that it’s logical that the particles/waves themselves don’t have the capacity to do all the partial derivatives and integrations to work out where they ought to be. They really should simply react to the forces they see at any point in time (here and now forces and what happens as a result) and though the resultant path may be a little complex such as a conic section, it still ought to be calculable using numerical simulation where we use timesteps and the configuration/forces at each point and thus step through positions of the constituent parts.

Of course, all these theories assume momentum is absolutely conserved in an interaction, and that apart from borrowing/returning to the Heisenberg energy bank, that energy is conserved too. That may not be a valid assumption. It’s almost certainly the net result after an interaction (we normally see energy and momentum conserved), but may not be valid during the interaction. If inertia is quantised (as seems to be true from cosmological observations) then this will apply at the particle level too, and rather than being a continuous range, momentum can only be exchanged (or changed) in quanta. It’s possible that this may change the maths quite a lot. A small force won’t thus affect the velocity (below the necessary force to jump to the next momentum level), and the path of a particle won’t be a smooth curve but instead a series of straight lines as the momentum has step-changes. I figure that might make some difference to the calculations….

Feynman was required reading when I was learning physics. He was good at explaining things, and where he found things that didn’t make sense he changed them so they did make sense. Probably killed a few sacred cows on the way, and his personal life was unconventional too. I see nothing wrong in watching his lectures for entertainment. I haven’t the time this morning, so I’ll watch them somewhat later. More fun than a Marvel blockbuster with fights between groups of people with magic powers.

@Simon; Excellent essay on the logic of the problem of waves that appear to be particles, particles that behave as waves. Quantaize the medium, Call it what you want. I prefer Aether and this results in Mass/Inertia being external to Mater, the thing that matters to me…pg

If you “kick” the Aether hard enough (voltage) and fast enough (frequency) It will kick back hard. Just like the results in a Tesla coil operation. If you are operating a cone shape field by pulsing a signal over a cone or saucer shape within the high voltage/high frequency field you are operating a linear motor within the activated Aether. Electronic Propulsion!…pg
