Inventing the clockwork radio
Is the wind-up radio sustainable?
Think about the following.
- The wind-up radio meets an important human need.
- It works on a renewable energy source (people power).
- It is manufactured in South Africa, using local labour.
- Many of the people who make the radios have disabilities, are ex-convicts or battered women. With the exception of the occasional wheelchair, it is impossible to tell the disabled from the able-bodied; the ex-convicts from the victims.
- The radios cost $80 to buy, but many are distributed free by governments or non-profit organisations. The Freeplay Foundation supplies them at a large discount.
