Foot Powered Sieve and Bandsaw

The Archanes Project, a natural building collective from Greece, shows two interesting designs for foot-powered machines: a sieve and a bandsaw. 

“When George Chiletzakis told us that he wants to make a bandsaw, that will operate without electric power, at the beginning we all laughed. It seemed that this gave him bigger strength and inspiration to show us that he who laughs last, laughs best.”

Decorated Mud Houses in Burkina Faso

“In the south of Burkina Faso, a landlocked country in west Africa, near the border with Ghana lies a small, circular village of about 1.2 hectares, called Tiébélé. This is home of the Kassena people, one of the oldest ethnic groups that had settled in the territory of Burkina Faso in the 15th century. Tiébélé is known for their amazing traditional Gourounsi architecture and elaborately decorated walls of their homes.”

“Burkina Faso is a poor country, even by West African standards, and possibly the poorest in the world. But they are culturally rich, and decorating the walls of their buildings is an important part of their cultural legacy in this area of the country. Wall decorating is always a community project done by the women and it’s a very ancient practice that dates from the sixteenth century AD.”

Decoupling of Economic Growth and Material Consumption is an Illusion, Researchers Say

“Metrics on resource productivity currently used by governments suggest that some developed countries have increased the use of natural resources at a slower rate than economic growth (relative decoupling) or have even managed to use fewer resources over time (absolute decoupling). Using the material footprint (MF), a consumption-based indicator of resource use, we find the contrary: Achievements in decoupling in advanced economies are smaller than reported or even nonexistent.”

“By calculating raw material equivalents of international trade, we demonstrate that countries’ use of nondomestic resources is, on average, about threefold larger than the physical quantity of traded goods. As wealth grows, countries tend to reduce their domestic portion of materials extraction through international trade, whereas the overall mass of material consumption generally increases.”

“Our findings call into question the sole use of current resource productivity indicators in policy making and suggest the necessity of an additional focus on consumption-based accounting for natural resource use.”

Is Cuba the First Large-Scale Maker Society?

“When the U.S. left Cuba in the 1960s, it took most of the Cuba’s engineers with it. In their absence, Fidel Castro encouraged citizens to learn how to make their own stuff. So, they did. And, in the 70s, a culture of garage innovation was born from the revolutionaries, scientists, mechanics, and ordinary folk who formed the National Association of Innovators and Rationalizers (ANIR).”

Update: The book “Con nuestros propios esfuerzos” (“With our own effort”), released in 1991 by Verde Olivo, the publishing house of the Cuban Revolutionary Armed Forces, is available as a PDF. This 300-page long compendium describes and illustrates in technical detail a vast array of artificats, recipes, and survival strategies collected from all over the island by local authorities. Read more about it here (starting at page 4). Thanks to Michele.
