Meta Shop Class as Soulcraft Book Review and Book Repair How-To

book1I recently picked up a great book from a used bookstore. Shop Class as Soulcraft: An Inquiry Into the Value of Work by Matthew B. Crawford is a fabulous book about what it means to be a person who works with their hands. Ironically, before I was finished, the hardcover edition from Penguin Books began to fall apart. So much for quality construction! A large section came loose in the middle, and then became completely detached from the spine. I’m faced with one of the modern dilemmas that Crawford points out in his book. Do I keep reading the book, letting it slowly fall completely apart? Do I simply throw it away and buy another copy? Or, maybe download an electronic version to my smart phone, perhaps? No, Dammit! I will fix it! [Read more…]

Sanders on Solar

Bernie Sanders presidential campaign is catching fire. What is his plan for solar?

Bernie-Solar
This week, in our continuing coverage of the candidates vying for the presidency in the 2016 election and their record on solar issues, Solar Tribune look at Senator Bernie Sanders. The curmudgeonly Independent from Vermont may seem an unlikely front-runner for the Democratic Party, but recent polls show that he is rapidly closing the gap with presumed shoe-in Hillary Clinton. With all of the buzz surrounding the Sanders campaign, let’s look at what a Sanders presidency would mean for the solar industry.

The Dymaxion House: The Tiny House of the Future, circa 1930

Buckminster Fuller understood the need for a move to tiny houses. Unfortunately for Fuller (and the rest of us), he was 80 years ahead of his time.

BlogIMG_0524
In the past 10 years, tiny houses have become extremely trendy, and not without good reason. The real estate market has proven to be turbulent, to say the least. Down-sizing to live within your means is a concept that is increasingly popular not only among millennials, but with their aging baby boomer parents as well.

Tiny houses – compact, single family dwellings under 400 square feet– stand in stark contrast to the American trend toward larger and larger homes that started in the 1970’s and peaked in the early 2000’s. The current fad in tiny houses utilizes highly designed, compact interior spaces that include most, if not all of the modern conveniences, while maintaining a very traditional, cute cottage exterior appearance that makes them more enticing to tiny house newbies. Despite their small footprint, tiny houses retain a warm, cozy feel, which is key to their appeal.

This charm factor, or more precisely the lack of perceived charm, may have lead to the demise of an early 20th century precursor to the tiny house movement of today. In 1930, visionary architect R. Buckminster Fuller designed the Dymaxion House, an 1,100 square foot cylindrical aluminum yurt-like dwelling that is as radical today as it was in the last century.

Solar and the Stock Market

As of this writing, the global economy is on an insane roller coaster and US stocks have lost $2.1 Trillion in the last week. Do we have any idea what this means for solar?

trina-solar-limited-adr-tsl-reports-strong-earnings-stock-up-244The recent problems began with news of a cooling Chinese economy, and this is important to solar watchers for a number of reasons. Although no one can say for sure how long the stock sell-off will last, some solar market watchers are looking at the implications for the solar industry in both the near and long term. Many investors are watching companies like Trina solar, who are being dragged down with the rest of the market, as good opportunities to buy and hold. Professional investors at Seeking Alpha believe that Trina, Junko and other Chinese solar manufacturers that have sound financial fundamentals and are showing growth may be looking at a strong rebound when the market finishes its correction.

Detroit Maker Faire – Motor City Mayhem!

Detroit! The Motor City! Despite having fallen on some hard times, Detroit is still my favorite American city, and the 2015 Detroit Maker Faire was a perfect example of why I love the place. Great people with great ideas are making it happen against the odds. Garage entrepreneurs rolled out their latest 3D printers and laser cutters, right next to teams of school kids exhibiting amazing DIY robots. Traditional fiber artists and woodworkers hob-nob with hackers. If the Maker Faire is any indicator of what’s ahead for the Motor City, Detroit’s best years are still ahead of it!


Kids of all ages learning to solder!Each July, Maker Media (the publishers of Make Magazine) partner with The Henry Ford museum in Dearborn, Michigan to “host two days of unconventional ingenuity, unbridled creativity and a whole lot of forward thinking.” I’ve been wanting to get to this event for the last several years, and this summer I finally made it. And it didn’t disappoint!

Airports Are Going Solar

Airports need lots of flat, open, unobstructed land surrounding them. Why not fill that open space with solar panels? Several large airports have done just that.

shutterstock_184455989This week, Cochin International Airport Limited in Kochi, Kerala (India) inaugurated a 50 acre, 12 MW solar PV plant, making it the first airport in the world to offset 100% of its usage through the use of solar. The airport also has another 1 MW solar PV plant in addition to a smaller grid-connected 100 kW rooftop system, both of which were installed two years ago. Also in India, the Indira Gandhi International Airport near Delhi installed a 2.14 MW plant last year.

According to solarlove.org:
“The Airport Authority of India (AAI), which operates 125 airports across the country, including the Cochin and Kolkata airports, has decided to build solar power plants at about 30 of its airports.
AAI has plans to install 50 MW capacity plants in the first phase (by 2016), which would be enhanced to 150 MW over a period of time.

Lasagna Gardening – Compostilicious!

Patricia Lanza wrote the book on Lasagna Gardening.Last year, I posted an article about double-digging, and how to turn some problem soil rapidly into a healthy garden that you could plant right away. Well, summer has flown by, and although I double-dug a new strawberry patch large enough for 100 strawberry plants (which are doing great, by the way) there is another old patch of garden that I started several years ago, and then abandoned because the soil was just hard clay, and I planned to amend it “next year.” Well, yes, another next year has come and is rapidly going, and I managed to keep the weeds down before they went to seed, but there were just too many other projects that took priority over that old garden. This time, I pledged to make a preemptive strike! I am going to start a large-scale sheet composting operation and make the garden a lovely warm winter meal of lasagna!


Sheet mulching is a permaculture technique that utilizes alternating layers of different types of compost materials. By alternating your “greens” (nitrogen-rich, fresh plant material like grass clippings and kitchen peelings) and “browns” (older, dry material like leaves or straw) you can create compost right on top of the garden, where it is needed.
