The latest in renewable energy living VALLA Linköping SE

Today the New York Times has a column by Thomas Friedman with title The Green New Deal Rises Again in which Friedman reminds readers that the US had shown signs of becoming green back in 2007 but did not get very far toward that goal. The article is, of course, illustrated by the standard NYT renewable energy ikon, a wind turbine.

I filed my standard comment noting that as far back as 1955 the Times reported that Green Energy was about to sweep through New England in the form of heat-pump technology. Never happened, and the Times almost never used those two words - heat + pump - together again. In my comment I point to the technology that is at its most advanced level in Sweden and Denmark as shown in the post below this one.

The goal of an ideal Green New Deal would be to make whole neighborhoods kept warm, well lighted, and even cool using 100% renewable systems. My neighborhood here in Linköping, called Valla, provides full-scale examples of how meeting such a goal might be met.

Best is the brand new wooden apartment building, Berså, about 500 meters from my home. I visited Berså this morning and introduce this Green New Deal building to readers today. I will be contacting the Linde Company, builder, to obtain technical information.

Valla Berså apartment building, Linköping SE. The goal in creating this building was to illustrate how far it is now possible to approach the goal of 100% renewable. The roof is covered by solar panels, and an electronic display at the main entrance shows how much electricity was produced by these panels each day. The building itself hides 10 boreholes, each about 200 meters deep, that provide the basis for the ground-source geothermal heat-pump system (GHSG) that heats this building now and that will cool it whenever even in Sweden the temperature calls for space cooling. Here is one of the displays that I will from now on monitor regularly.

I believe this shows daily solar energy production but cannot provide exact information until I have made contact with a technical representative at the Linde Company. What interests me most is to learn in detail how much heat is delivered to the building each day by the GSG system and ultimately to compare the efficiency of that system with the efficiency of the solid-waste incineration system that delivers heat to all the buildings that surround Valla Berså including mine. The next picture shows how you can tell that my home is heated by "fjärrvärme"/distance heating.
Snow fell last night and covered the ground completely, even my front yard shown here. But there is a pipe buried under my front yard that connects to the pipe that feeds hot water to my neighbor, a pipe installed several years before mine. Today, with temperature outside 0 C, water flowing in the pipe enters a small white box in my basement at a temperature of 80 C. A heat exchanger system draws heat from that incoming supply and heats water in two systems, one the radiator system that heats my home, and the other the system that delivers hot water to bathrooms and kitchen. The whole system is silent and the best I have ever experienced.

Next door on the other side is the one home on the street that does not use fjärrvärme but instead has GSG. The previous owner of that home was an engineer who got permission to have a GSG system installed about 10 years ago. That system is of course invisible, there is a borehole about 120 meters deep that contains the tubing through which fluid circulates to capture heat from the bedrock and bring it into the basement to keep that home just as warm as mine. The engineer told me when he was moving that the system had functioned perfectly for those first 10 years and with maximum efficiency.

Last but not least are the solar panel installations that have been spreading on top of older apartment buildings across the street from me and are becoming ever more common on new buildings including the newest here in Valla. Here are the newest installations on an older building.

The solar panels are covered by a dusting of light snow and feed electricity to the integrated system also fed by the local network. Out in the farm country north of where I live there are vast solar panel systems on farm buildings and often close by giant wind turbines supplying electricity for the large dairy farms that dominate in the plains of Östergötland.

Back in the New England I visit every summer I still see old-fashioned oil trucks delivering to homes, propane tanks in back of homes, and natural gas pipelines tearing up the landscape and occasionally providing the fires and explosions that wracked Lawrence and Andover MA a while back.

I prefer silent renewable and you would too if you had access to it.

The World's Two Best Solid Waste Incinerators

For New York Times Readers
and anyone else who has never seen or lived near a solid-waste incinerator
as advanced as these two.
The top one is Copenhagen's newest and the one below that is Linköping, Sweden's newest.
Both were designed by Danish Babcock & Wilcox.

Gärstadverket, Linköping SE
Donald Trump, my President, has a representative in Poland right now, December 2018, telling conference participants that we must keep burning coal to generate electricity and implicitly must see to it that landfills will continue to grow, landscapes will continue to be defaced, and trains will continue to cross America bearing the coal he loves so much. Not me. Older posts deal with this subject. This post is intended for the rare NY Times reader who sees my comment if and when accepted, next to the Times report from Poland today 11/12/2018

Time To Look Back in My Blog

Many years have passed since I started this blog, and today, November 9, 2018 I wanted to find a post that tells several different stories, a post that was and is very important to me. I found it but confirmed that all of the older posts are seriously damaged and are missing images or videos that have been replaced by either a large exclamation mark or yellow space.

It does not appear to fix these posts, so I am copying each post to a Word file in which I can insert the jpgs and mp4s that were removed, if I can find the originals.

I have to consider whether or not I should start a new blog at another location, WordPress for example. I have tried to get answers from blogspot about the damaged posts but cannot find any answers.

Therefore I post this as a message to myself. I even learned that I really should have gone to my own blog when some question arose at the current New York Times, a question I knew I had dealt with in comments. It turns out that long ago, maybe before there was a comment section I wrote here.

No pics just now, something would be appropriate and I have one in mind. Maybe tomorrow.

19:53 GMT Friday, November 9, 2018 and it is TGIF
Every TGIF evening I try to do something special and different and I have done that by working on the second half of a document: A Theory of Love - It's All A Matter of Time.

Renewable energy / incinerator technology-update for New York Times readers

I am on an island in Sweden and must refer readers looking for posts on renewable energy and especially Swedish Danish incinerator and heat pump technology to older posts. 2017 has the incinerator with photographs.

Cannot update here until I am back in Linköping early next week.

Saturday October 13 - on Styrsö in a home heated and cooled 50% at least, often 75% by a 10 year old air-air heat pump that is silent, more efficient than fossil fuel, and runs on 100% renewable electricity energy. I do not believe there are any fossil-fuel systems on this island.

Additions to David Brooks NY Times 27 July - my comments with pictgure

David Brooks is a New York Times columnist whose columns regularly appear in Swedish in my Swedish newspaper, Dagens Nyheter. The New York Times has the best comment and comment review system of any publication known to me, and I often comment there using Swedish examples in comparing a situation in the USA with a similar situation in Sweden.

Here is my first comment accepted at the NYT at 09:00 h CET (3 AM EDT):

Larry Lundgren

David, I look forward to seeing your American Renewal story in Swedish in Dagens Nyheter, DN, right beside me as I write this first submission. I have been a volunteer at the Red Cross working for the past 18 years in programs intended to help asylum seekers learn Swedish and do well enough in school to eventually be able to study, free, in college or medical school.

I support volunteer programs. But as Socrates, no. 1 R Pick writes: Community and volunteer programs are lovely...but are no substitute for humane policy and good government. 

I translate from the front-page story in DN 7/25: "There are very few families with children (in Sweden) that suffer from serious poverty". Inside a graph shows that the percentage of children age 18 or younger who suffer from "material poverty" is the lowest in Sweden (0,7 %) of all18 EU countries studied. 

Larry LundgrenSocrates reminds us that the USA, by contrast, has the highest rates of poverty in the developed world. USA would be off the chart in the graph I cite. 

My admiration for Sarah Hemminger is unbounded. A congress with more women with her kinds of experience, empathy, and education would be a first step to setting a distant goal of making America humane again. 

Vote in November. 
Citizen US SE

In a second submission I call attention to reporting in DN on a situation taking place in Indiana as being far more powerful in presenting a message than NYT reporting on that situation. I place in focus a photograph that appears on the front page of DN today, 7/27. I provide a copy of the front page since US readers will not be able to see that picture if they try to go to DN at Only in the e-Edition can the front page be viewed.

American Dilemma - My 21 Days On A Mountain 2018

I have been lucky enough to have spent the past 21 days or so here in my home away from home, Cedar Shelter up on Mount Philo in Vermont's first state park, Mount Philo State Park just south of Burlington.
The Swedish flag is there to indicate that even though I was born long ago in Attleboro, MA, I have had the good fortune to keep a promise to my grandmother Hulda, to visit or even move to Sweden, the country to which she was never able to return.

Here is the paradox, the extreme American dilemma: On every single one of those 21 days I experience the America I would like to believe in, a place where people with countless different lines of descent can live an create new lives as did my grandparents and great grandparents after they came from Sweden.

I get the chance to meet these people here at two distinctively American places, Speeder &; Earls and Muddy Waters. Here we are at S & E where I encounter a familiar scene, creative people at work, here two artists discussing layout using the acrylic work of the young artist to the right.

And here we are at Muddy Waters where just about everyone seems to be doing something creative, studying, painting, drawing, writing a book, maybe even closing a million dollar deal. Here my final-day barista question: Anybody here speak a 2d or 3d language was greeted with "Yes, Farsi or Persian, came here from Iran."

And every night up on Mount Philo I can enjoy the peace and the beauty provided by the changing scene before me, Champlain Valley, Lake Champlain, and the Adirondack Mountains. As a future geologist I first worked in the Vermont mountains while a geology major at Brown and then as a doctoral student at Yale I worked in the Adirondacks exactly in the center of the skyline.

What more could one ask for, to grow up in a place where the experience of nature mattered, where people of different lines of descent could get along and create music, art, science, literature?
And yet in this America I learn every day from Vermont Public Radio and the New York Times that the goal of the present government of the United States is to tear all this apart.
So as I drove down the road to Mount Philo last night, I thought about Gunnar Myrdal and his "An American Dilemma" the continued practice of segregation in a country that professed to have moved on beyond that. Up on Mount Philo I opened the only paper copy of the NYT I have read in my 21 days, and there saw the headline above Paul Krugman's column "Fall Of The American Empire"
and there in the text was Krugman having that same thought leading him to point back to one American Dilemma still with us, racism now as presented to us by our president.

Where to go next from that start? Very likely to compare some elements of the situtations faced in my two countries, the United States of America and Sweden.

Now I am leaving Speeder & Earl's to visit in Winooski where I hope to find out where my friend Abdi Dhare has gone after his Banadir Market and Halal Store were gentrified into oblivion some time in the past two years.

I was successful at Somali Bantu and was able to talk with Ahmed who speaks English, Somali, Mai Mai and maybe more and he helped me to connect with Mohamed who went to Kenya last year.

Next stop was B & N Bookstore in South Burlington, also a great home for me, so many books (have bought some) and the usual nice people. So as always on my last visits I ask the baristas if any of them speak a second or third language after English and the quick answer was, "Yes, Russian and some Japanese" from the young woman who is almost always here. In the context of my post, I wonder what you know who would say if we told him how many helpful people I meet here who came from other countries or who are so-called 2d generation immigrants, born here.

Anat Cohen takes a Giant Step from jazz saxophonist to Choro clarinetist

Anat Cohen was Artist in Residence at the Burlington Jazz Festival 2018 and then at an interview explained for all of us who have known her as a jazz saxophonist what led her to take a giant step to playing clarinet with Brazilian practioners of Choro. Here is a sample from Flynn Space.
