3D Printing
This morning I finished reading a article in Business Week on how 3D printing is being used in the health industry to rebuild body parts. I then picked up The Economist and when I opened the cover I saw a add for 3D Printing. The history of 3D printing is short, just a laboratory fantasy project in the early 80’s. In the late 80’s Steve Crump and wife Lisa developed and patented a 3D printer process. They formed a company called StrataSys located in Eden Prairie Minnesota. StrataSys has a annual sales of over a billion dollars.
My own journey started in 2007 when I started to hear the phrase “additive Manufacturing” and then 3D printing. When the Hazelton building was built, the vision was to someday have a molding operation added to our building. This was soon replaced with a vision a vision of thirty or forty printers making RightStart manipulative on a just in time production basis.
But the cost was prohibitive! Machines were $30,000 each, one color and plastic material was $30 a pound. But this was the year 2009. This Christmas Joan and I bought a hobby machine for $2500 and material was available in various colors at $15 a pound. On April 1, 2014 our machine is absolute! In January MakerBot introduced a  two color machine.  And today it was announced by Stratasys they have developed a multi color 3D printer. Very soon material will be in the five to seven dollars a pound, well in the cost range to print a ALabacus.

 So what next for Activities for Learning and 3D printing? Stay tuned!

MY RETURN

MY RETURN!

On April 11th, 2013 was the last entry in my blog. In this blog entry I will continue to blog about the past as in my last entry. New entries will be about the future.
In this  entry I am publishing a time line of my life. The previously published entery was events about this time line. The event entered for last year. “Incapacitated  in May and June”’ is the reason. I am now 125% better and back to work.
My life time line was started several years ago and only records major events. My purpose was to some day write a book. But a timeline does not every thing about our lives. Every body has memories growing up that are interesting and sometimes just plain funny. One such event I remember is hiding in plain sight from my mother. The event occurred sometime in the late thirties.
It was after I had an operation and I was recovering and bored. I used to get around by “hopping on one leg” and could travel quite a distance. The distance from our house to the windmill was only about a 100 feet from our house. I climbed up the windmill tower, about forty feet in the air. Then I called Mom. The dialog went something like this:
Mom: “Where are you?”
Me: “I’m here!
Mom: I can’t see you.
Me: I can see you
After several exchanges Mom looked up and there I was! Sitting on the service platform with one complete leg dangling and another incomplete one.
 When I got down the story is not funny any more.
Subjects I will be blogging about in the future are technology, energy, economics and, of course, politics.

Next, 3D printing!

Now my milestone timeline.

80 YEARS


“It was a dark and stormy night” when the second child was born to Edward and Erma Cotter, named Alvin James. It was February 27, 1933. I was born in a farmhouse with my father as midwife.
O’K’, the phrase  “It was a dark and stormy night” is plagiarized from Victorian novelist Edward Bulwer-Lytton, the opening line of his novel PAUL CLIFFORD.  What follows is not fiction; it will be about milestones in my life.  
My mother said I was a curious child, into everything. This curiosity led me to the second major milestone in my life. I just had to go see what Dad was doing in a field near the house. The result of my inspection was the amputation of my left leg.  Followed was a series of operations, new artificial legs and with the last operation the year before High school and the last artificial leg purchased with out insurance in 1969. My parents purchased a new leg every three years. Was this all bad? No!, I became an avid reader. My Dad and Mother who also enjoyed reading and subscribed to several magazines. And I went to the library in Prescott Wisconsin, my hometown.  I recall reading the “Country Gentleman” For hours and re reading them again and again. I was “allowed” library privileges, because I was the Cotter kid with a limp. I had a new leg every three years that was only the right length for one day. I recall visiting the Case implement dealer and reading the Nebraska Tractor test book. Did you know a1939 John Deere B produced 8-horse power per pound of fuel? I did. A Farmall H would produce 10 horsepower per pound of fuel. But Dad bought a John Deere B with a hand clutch so I could drive it. My mother was very concerned about my education. She said I needed to prepare for a job where I didn’t have to “work”.
The third major milestone came after a lackluster High School experience and one year of College at River Falls State College. I had no idea what I wanted to do with my life. I wanted to farm! So I decided to get a “high paying” union job at the packing plant in South Saint Paul and to make enough money so I could farm. I was not hired; because I was a cripple. I was so dam mad I drove to Saint Paul and started the next Monday at the American Hoist and Derrick as a Draftsman. I had one semester of drafting at River Falls State College. After six months at the American Hoist and Derrick, I moved to 3M.
After three years at 3M, I was told that I had potential to be an Engineer! This was a major milestone. Also 3M Engineering and personal department (HR) said they would help me enroll in college and pay tuition. I started at the University of Wisconsin majoring in mechanical engineering. While I was a twenty four year old freshman, I probably wasn’t any more mature than the eighteen year olds, so I fit into dorm life and was president of my Dorm in my sophomore year. The U of W was clearly my fourth milestone! I graduated in 1962.
My fifth milestone begun after graduation when I was offered an engineering job with Eastman Kodak and a counter offer from 3M.  I accepted the 3M offer, which took me to Saint Paul Minnesota instead of Rochester New York. There I met Joan Donohoo my future wife and life partner in future milestones of my life.
The next milestone in my life was our moving to Hutchinson Minnesota with our now three children, Kathleen, Constance and Andrew. The year was 1969. And the remarkable part of the move to Hutchinson was not the decision to move to Hutchinson verses California, but that Joan, a city girl, took to the small town as an adventure and approached frustrations with humor.
And then the move to a Farm! In the late summer of 1971 Joan was taking a bike ride in the country. She saw a for sale sign on the south tip of Otter Lake. We had a fantasy of someday building a home on “the lake”. The lake property was a part of a 140-acre farm. On October 1 of 1971 Joan and Al owned lake property with 110 acres of cropland attached, crops to be harvested and 150 chickens. The rest of this story is long, but to summarize, the home on the lake soon escalated into fantasy of part time hobby farming, to full time farming exploring new farming methods. The purchase of the farm was a major milestone in my life!
Twenty years after the farm purchase, I retired from 3M and started to fulfill the fantasy as a full time farmer. This did not go as planned. I was recruited to run for Parish Council and despite not attending on election Sunday and I still won.  Also as a chronic complainer about the price of corn (a farming addiction), I got involved with county corn growers, soon elected to state board as a director, Because of my science and engineering background, I became involved in research on the national level. It soon became apparent to me how big a gap in experience I had about the role of government. At this point I thought of government as an organization who confiscated my wages through taxes and issuing me speeding tickets. I soon become aware of governments role in infrastructure and basic research.  Two examples of infrastructure are the Erie Canal and the issuance of land for building railroads and our Land Grant College system.  Was my involvement in Corn growers a major milestone?  Maybe not, but it was a significant part of my educational life experience.
The final milestone is Activities for Learning (AfL). AfL is a result of Joan’s study and work developing the curriculum “Right Start Math”  < http://rightstartmath.com>. My role has been many. First and foremost have been the support, encouragement and council to Joan in the development of her method of teaching math to children. While this role will continue, I have been able to help develop a company to publish Joan’s work so children can “understand, apply and enjoy mathematics”.  And I am still enjoying working on this milestone!

THE BIG ISSUES OF 2013


I will turn 80 in February. And I am enjoying the good life! And I am looking forward to my new car, a ………………
My goals for Activities for Learning is to develop and evaluate a automated order taking system using a iPad for conventions, implement stage one of 3D printing and  improve the accounting system.
I have rented .06 acres of land from Andy and Irene to plant four varieties of sweet corn, 65 day, 75 day, 85 day and 95 day. I have offered them $16.50 which comes to about $300 per acre. Mike Genelin, Irene’s father, has offered to be my partner and will be paid in sweet corn. Mike and I will build a one row planter, using a “recovered from the grove” JD 71 planter unit, mounted on Andy’s hi-crop Yanmar. I haven’t told him about ridge tilling and irrigation plans yet.
There are some very serious problems that I will track and comment as 2013 plays out. They are the national debt, entitlements, the environment, and energy.
The national debt needs a systematic solution, not a cut and slash. Reducing the debt is very complex. For every domestic cut, means someone will lose a job. That job lose could turn the economy into another recession. Increasing the debt willy-nilly will cause investors to lose confidence and cause another recession. For every cut in foreign spending will have opposition. The first step is get out of Afganistan.
There are ways to reduce the debt, but it will require education, change, education and more change. (see December 25 post). Much more will be covered in a later post.
Entitlements will have to be cut. More on this subject in later posts.
Protecting our environment has to rise in our priority list. Global warming will have little adverse affect on me, but it will be a major concern for Carson, my one year old great grandson. Changes made in the way we live will require change in many ways. It will redistribute wealth in ways not imagined now and will change the function of government. A major topic of discussion needs to be held in upcoming years and resulting change in the way we live. The solutions will develop around these five words: Recycle, reuse, refuse, research, and reduce.

THE SECOND AMENDMENT


A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed.
Above is the second amendment. Today, on this December 30th day it is a topic in many newspapers. None that I have read has told me what the second amendment says. I am going to share with all what I think it says. Books have been written about the second amendment but I will deal with some basics. The second amendment was wordsmith by the founders of our country and was an amendment to our constitution. The important thing to remember that history reveals the  founders were a diverse group of men and didn’t much trust one another. To use a example of mistrust; Hamilton and Jefferson.
The one thing they all agreed on that never again did they want to be under the rule of a tyrannical government. At that time an residence of Georgia and New York had little in common in the way they lived. Because the framers of our constitution had fear of other states, they wanted to make sure they could own arms. I speculate arms were to be regulated so neighbors would not lobe cannon balls at one another.
I see no relationship with gun laws for individuals that are not a part of a militia or a police officer today and the second amendment.  Does the second amendment allow me to mount a AIE-486H heavy machine gun with a 800 round per minute fire rate on my deck?
The recent Newtown incident begs for common sense gun regulation. And it is time we start apply our reading skills and read the second amendment.

INNOVATION


Which comes first, innovation or change. In this Blog series change came first. I will argue innovation and change both lead and lag one another depending on the circumstances.
In 2011 President Obama announces 54.5, mpg fuel efficiency standard by 2025. Consumers are projected to save $1.7 trillion at the pump or $8,000 per vehicle. Why? This is being done because of change, population growth. Read previous Blog entry dated December 26. If we are to reduce the release of gases that cause Global warming, we must increase the mpg of passenger carrying vehicles.
In this case innovation is ready! In fact it is easy to argue that past innovation make the 54.5 MPG achievable today except for culture and economic barriers.  Today five passenger cars are being made today that exceed 100 mpg equivalent, two of them made by Ford.
The innovation of increased mileage will cause more change. In the year 2000 the EPA fleet was about 24.5 mpg. If half the amount of gasoline is used in the United States in 2025, a major change will be made in the petroleum business. This is just one example of innovation causing change.
Another example of innovation causing change is the CFL bulb, which uses 60% less electricity. This is causing a major shift in electrical power consumption and in the economy.
Innovation can be stopped. The way to do it is through the education system. If we stop educating craftsman, technicians, engineer and scientist, innovation will slow and then stop.
