Peer-to-Peer Wireless Is Increasing Competition Worldwide

U.S. regulators have been attempting to deal with the negative affect that a few large Internet providers might have on competition. Meanwhile, elsewhere in the world, new mobile technologies have been encouraging competition.

Yesterday, at Mobile World Congress in Barcelona, Spain, the chairman of the U.S. Federal Communications Commission, Tom Wheeler, promoted the net neutrality rules that the FCC recently voted to adopt, and bragged that the U.S. would “continue to be the world leader” in high-tech telecommunications. The FCC’s rules would prevent Internet service providers (ISPs) from prioritizing certain content. Critics say such “fast lanes” would undermine the principles that have led to online innovation (see “FCC Chief Proposes Broader Net Neutrality Rules”). Continue reading

Who Are You?

I often travel to different countries chasing stories. It’s hard for me, let alone my credit card issuers, to predict where I’ll be at any given time. This summer, for example, I moved from Madrid, Spain, to Oaxaca, Mexico, and in November I made quick trips to both California and Nicaragua. Confused by my unpredictable spending patterns, my credit card companies often block my legitimate transactions. Continue reading

Recyclers in Ixtlán de Juárez, Mexico, learn how to separate plastic bottles for recycling into much more valuable 3D printer filament.

3D printing takes off in Oaxaca

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.

Building a New Economy on Soda Bottles and a 3D Printer

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.
