Thirst For Coltan Fueling African Conflict

MetaPhyzx writes "According to an article put forth by the Toward Freedom website, the metallic ore known as columbite-tantalite or coltan for short is fueling conflict in central Africa. The relevance to us who read news for geeks: Coltan is in quite a few consumer electronics; the article references the Sony Playstation series." As reader fahrvergnugen points out in the comments below, there's reason to more than doubt the currency of the claims in the above-linked article, as outlined in a post at Joystiq.

Tantalum is used in small quantities to make high-performance and compact electrolytic capacitors.
Typically a tantalum cap will have lower leakage current and be about 1/4 the size of a aluminum electrolytic, at about twice the cost.
As an electronics repair guy, I just *love* tantalum caps, as they quite often short out given an opportunity. Most repair places won't even try to do component-level repairs anymore, so that leaves lots of nice equipments for me to fix.
