If you're a regular listener to Spark, you've probably heard Bill St. Arnaud. Bill is an Ottawa-based green IT consultant, and he also runs an email newsletter that covers issues related to green IT. Recently, Bill wrote about a Berlin-based startup called Changers, which has developed a solar-powered gadget charger.
Solar-powered gadget chargers are nothing new, but Changers is different in that it's trying to build a social network on top of lowering carbon emissions.
Last week, Nora interviewed Hans Raffauf from Changers, and Bill St. Arnaud. You can hear the full, uncut interviews below, or download the MP3. [runs 15:21]
