Capacitors from the Congo

Bill Hammack makes instructional videos about engineering in everyday life. In this episode he explains why the conflict mineral Tantalum is used to make cell phone capacitors smaller. Even though only 2% of the raw ore Coltan originates in the Congo, it is impossible to trace in its refined form, which means that the 40mg [...]

Another amazing resource for anyone who wishes to know more and act with information when choosing products or choosing which issue to tackle – the US Department of Labor’s List of Goods Produced by Child labor or Forced (slave) Labor (publicly available in pdf format).

Evening Ware

As a frequent attendee of computational couture/fashionable technology/wearable computing events, I’ve grown suspicious that computers could become a seamless extension of Fashion. Until Thursday, when I was lucky enough to attend Diana Eng‘s runway show at Eyebeam Atelier.

Fashion without Trash

The fashion industry is the poster child for un-sustainable practices, as we’ve already seen from the myriad of social and environmental problems plaguing the cotton trade. Fashion designers share the responsibility, because they are so remote from the means of production – usually outsourced to Southeast Asia, Africa or South America – that their designs [...]

Heat Local

Last week John took me to see Highland Wood Energy, Scotland’s largest biomass heating company. While the idea of burning wood is not particularly new, modern chip and pellet furnaces provide a uniquely sustainable solution for regions with a natural overabundance of wood (whether from natural growth or industrial waste). In particularly isolated regions like [...]
