No/Low Tech Magazine

Kris de Decker produces some of the most insightful and well-researched articles on technology anywhere on the internet.  He has a simple premise- novel “high-tech” solutions aren’t always that great.  Don’t give up on established, simple, and efficient solutions to human problems.  He just linked back to me when I pointed him to KMODDL, and I wanted to share some stuff he’s posted, since it’s been sitting in my “to post” folder since August:

Kris often finds works from another age whose techno boosterism is familiar, but whose object is odd to a contemporary reader. From the height of airship mania ( Zeppelin’s commercial air transport service was established a year later) and before airplanes proved themselves in the skies, Airships Past and Present (1908) is a fantastic snapshot of globalized tinkering and ingenious innovations:

In 1792, Uyton de Morveau recieved official instructions from Napoleon to develop military balloons.  Morveau developed a team with chemist Lovoisier and physicist Coutelle,  and together they developed a novel hydrogen generator that used a hot iron with steam passing over it, and a novel means of sealing silk balloons with 5 layers of linseed oil based varnish.  The varnish was particularly effective, holding hydrogen in the balloon for upwards of 2 months, but the recipe is lost to history.  The envelope of a hydrogen balloon capable of carrying 2 passengers to 1600ft  would weigh only 180-200lbs, in line with early 20th century numbers (134).

OR:

My favorite balloon of the period, the Parseval-Sigfeld, featured with hard numbers on wind speed (66ft per second).  Parseval invented the “sausage” balloon design that once refined was deployed by Germany, France, and to great effect Belgium in WWI.  But this text is of course from before the war (209, 211, 274).

Re-Burbia non-finalists: Me and Molly

Molly and I only gave the Re-Burbia Competition 4 hours, and Inhabitat/Dwell didn’t like us.  That’s ok, we entered because we don’t like them either.  Our friends tell us we complain about Dwell too much and architecture competitions ad nauseam.  As expected almost all the finalists use stale computer rendered crap images.  This project I thought had the right idea (albeit no citations) and good presentation, but like the rest it still depends on infrastructure investments that just ain’t gonna happen. Here’s our entry (I wrote/found citations while Molly illustrated), with extended text intro critiquing suburb resuscitation:

SCRAP THE BURBS

The wreckage of unsustainable industrial neighborhoods are already a new frontier of reduced density within re-awakening urban centers.  While the success of urban neighborhood renewal is an attractive image easily transposed to suburbia, urban neighborhoods already have a social and infrastructural fabric to weave back into.  The suburbs don’t.

Without cheap transportation, heat and power, people will return to more traditional town/country boundaries that are land, energy, and socially efficient.  No development plan will succeed in maintaining the current population density of land cut through with dead-end roads and divided into oversized and poorly sited bedroom houses sitting on 1/4 – 1/2 acre plots.  As places like Flint, Michigan have realized, the question is not, “how will we stay here”  but rather, “what is this place worth for scrap?”* Suburbia was born in an era of cheap energy, and will die with it.

In the near future abandoned suburban tracts will come up for auction.  Confronted with abandoned houses and neglected infrastructure, what resources do suburban homesteaders have, and what can they do with it?  Much of the topsoil is of low quality. But intensive and profitable agriculture is definitely possible:

In 2002 a new house had 18 windows** a standard window is 30″x60″ or 225 sq. ft. of window per house

In 2008 94% of new construction had 2+ bathtubs, 28% had 3+***

A 60 gallon bathtub can raise 57 pounds of tilapia****

One cubic meter of asphalt pavement can by pyrolized into 58.4kWh of energy*****

The conversion process:
Build a small, solar-cited house with scrap lumber and all your favorite ornamental features.  Just enough to get going, and preferably near other homesteaders.  You can always expand later.

Properly cited, human-scale dwelling
Pull the windows out of all the houses on the block.  Build one amazingly insulated double-pane greenhouse, built over a swimming pool if possible.

recycled-window double-pane greenhouse

Use the pool as a giant fish tank (and thermal mass for the greenhouse) or set up the tubs, sinks and plumbing as a freshwater marine habitat.  Crushed concrete may be a substitute for a limestone filter.  Useless suburban basements often need pumping to stay dry, use a found pump for water flow.  Grow vegetables in aquaponic beds drilled into PVC drainage pipe.  Use nearby roofs to collect rainwater.  Your greenhouse will provide even with bad/unpredictable weather.

P1050319
Form a pyrolysis co-op with your fellow homesteaders and tear up unnecessary pavement.  Crack it into fuel and drive surplus aquaponic goods to market.  Use the money to buy animals and begin grazing  nearby land.   House them in a converted McMansion barn, and save silage on the second floor.

tear up the roads and make fuel
Graft edible fruit trees onto ornamental trees like cherry and crab apple, if you don’t have any, plant some.  Collect and feed acorns to pigs.

Use satellite dish reflectors and abandoned wifi routers to maintain a local network- you need to stay in touch. Enjoy your friends, and don’t plan on getting rich.

Coop with Simple Egg-Collecting Laying Boxes

Molly and I made a chicken coop last week with laying boxes designed after those on her father’s farm.  As far as we can tell, they’re a Gunnar Danielsson original design.  The laying box depends on chickens’ instinctual egg rotation.   Every time a chicken stands up off of an egg, it kicks the egg a little, rotating it.  In Gunnar’s boxes the floor is sloped just enough so an egg starts rolling when the chicken kicks it, and ends up underneath a hinged drawer.

Molly's Nesting box plan

Molly drew out the design and I did tests and built it while she was out of town.  It’s 70″ long, accommodating five 14″ laying boxes for large Buff Orphingtons.  Five laying boxes should be enough for 20 hens total.  First I determined a proper angle of between 10-12 degrees for the floor, then built the box.  The laying boxes are still missing curtains, but Katie will sew them up.  We built it all into a coop that will have a deep mulch floor, per plans in the Integral Urban House Book.  Soon the coop will have swinging perches too.

Katie Festinger’s Farm, pt 1

Molly and I have been working/staying at Katie Festinger’s nascent farm in Chimacum, WA (near Port Townsend) on and off for the last 3 weeks.  Katie sought workers with carpentry experience through Washington Tilth who shared an interest in Christopher Alexander’s Pattern Language building and analysis methods, and found us.

We’ve had a great time living and working there.  Katie, Beth and Dan are all wonderful and caring people to be and work with, and the area is gorgeous.  We really connected personally, and I hope we’ve made long time friends.  Molly described the area as “exactly like Sweden only more stuff grows and it actually gets warm.” I hope we get to go back some day.
