There are people who are just born do get there hands dirty. They are do-ers, they see a problem and they look for a solution. If a solution already exists, they make it better – if there isn't one yet, they invent a new one. This is what it's like at Alterna. The office is a bee-hive of activity, with tools piled on tables and machines in various states of disrepair lying around the office. When we visited, they were converting their workshop into a production plant for efficient cookstoves, and we had to struggle to get the filming done during the few moments someone wasn't sawing or hammering or just banging around trying out something new.
