Technology for Luddites
All the modern things
like cars and such
have always existed
they’ve just been waiting in a mountain
for the right moment
listening to the irritating noises
of dinosaurs and people
dabbling outside
all the modern things
have always existed
they’ve just been waiting
to come out
and multiply
and take over
it’s their turn now…

“The Dugout Canoe Project (.pdf) began as an experiment to use traditional Native American technologies. Archaeologists are reliant on just a few ethnohistoric sources that mention how Native Americans made dugout canoes using stone tools and fire. Numerous contemporary examples of dugouts exist, particularly Plimouth Plantation’s Wampanoag Indian Program, made by burning and scraping out logs. However, to the best of our knowledge, no one has attempted to fell a tree using only stone tools and fire. We wanted to see if we could cut down a live tree using these technologies, something that may not have been done in this area for several hundred years.”
“Dugout canoes are probably the first type of boat ever made. People from all over the world made dugouts. They were widely used in North America before the arrival of Europeans. Dugout canoes were made by Native Americans across North and South America for transportation and to hunt fish with a spear, bow and arrows, or with hooks made from antler or bones. In Eastern North America, dugout canoes were typically made from a single log of chestnut or pine. Carefully controlled fires were used to hollow out these logs. The fires were extinguished at intervals to scrape out the burned wood with wood, shell or stone tools, giving the canoes a flat bottom with straight sides.”

“Energy storage becomes more important as we transition away from fossil fuels—already its own energy storage medium—to more intermittent sources. But besides batteries—which offer a limited number of cycles and for some types require monthly maintenance—what other non-fossil in-home energy storage alternatives might we consider, and how much energy might we expect to store in each case? We will look at gravitational storage, flywheels, compressed air, and hydrogen fuel cells as possible options. Some might even cost less than $100,000 to implement in your home.” Read more.
“In mountainous areas, winds are often complex and the available wind data are limited and provide little information on wind direction. One technique for determining the mean wind direction is tree flagging. Trees have been used for hundreds of years as an ecological indicator of wind direction, wind exposure and as a measure of the severity of wind and ice damage. This handbook will describe techniques for ‘reading’ the information written on the trees by wind.”
“Flagged trees only reflect the prevailing wind direction of the strongest winds, which may occur during only part of the year. Seasonal variations in the wind have a pronounced effect on the type of wind deformation and these effects are characterized in this handbook. Techniques for estimating the mean annual wind speed have been developed using indices of wind effects on trees. These indices have been calibrated on two widely distributed species of conifers. The main conclusions are that trees provide a simple, inexpensive and quick method for identifying promising locations where more detailed measurements can verify the wind potential.”

“From Dust to Edge is the documentation of a long journey in the efforts of making a blade out of homemade steel. My interest in blades started with the legendary Japanese katana and as a result of wanting to learn more about how they were made I ended up becoming a bladesmith.
I combined the traditional Japanese techniques and the current knowledge of the Western smith in this pictorial representation. The project will be divided in several sections. It is primarily a visual description through photographs.”
