My kid has been going to Energy Explorers camp at Newton North this week. Yesterday he proudly showed me his wind turbine. He learned that, to make it work, you just need to put it in front of an electric fan! What’s more, the turbine wouldn’t fit in a backpack without breaking, so it was suggested that I bring a car instead of a bike. Fortunately our bike cargo trailer is going to allow us to both (a) spin the turbine and (b) get home, using renewable rather than fossil energy.
