A busy street climbs a hill on the edge of Oaxaca de Juárez, the capital of the state of Oaxaca in southern Mexico. Up one flight of stairs in a fresh-painted white residential building you’ll find the FabLab community fabrication center and Oaxaca’s first locally-produced 3D printer and plastic extruder.

This month, U.S. President Barack Obama’s administration began opening the long-closed diplomatic door to Cuba. Among other things the President’s plan makes way for is the ability of U.S. companies to sell telecommunications equipment to the island. Legislation imposing a broad economic embargo still stands, but the administration has some leeway over activity that improves the flow of information under the banner of “spreading democracy.”
(Exceptions to the old embargo abound: the U.S. National Science Foundation actually provided Cuba’s first Internet connection in 1996 as part of a broader connectivity drive for developing countries.)
Luís Euxebio Irías Calderón is the operator of a small hydroelectric power plant in the mountainous coffee country of northern Nicaragua, and he’s singing a song he wrote about turbines and transformers, to celebrate the arrival of electricity here in his remote corner of the country.

On a steep road on the outskirts of Oaxaca de Juárez, Mexico, a low buzz and plastic fumes emanate from a white house. A ribbed white paper tube snakes out of a window on the building, exhaling a light smoke which mixes with fumes from nearby open-air cooks and the sooty exhaust of rumbling, unmuffled bus engines. Inside, the tube is attached to a machine that’s gobbling plastic flakes—which can come from used drink bottles—through a funnel also made from a plastic drink bottle. At the other end of the machine, a spinning wheel draws out the fresh-melted polymer into a black filament just three millimeters wide and value hundreds of times what it was worth in in bottle form.
