A giant solution to a huge problem

Wind turbine blades can be 50 metres long - that's like four buses lined up end to end. How do you get them from the factory to the hilltops or offshore islands where they can generate the most power?

The answer today is that they mostly travel by road, on monster trucks that, like most trucks, belch out plenty of carbon dioxide. So creating something that's good for the environment - wind turbines - means starting with something not so great.
