How's The Air Today?
In a further attempt to show how eco-unfriendly our daily lives have become, the French have come up with an innovative way to draw attention to the air quality in Paris.
A colour-changing helium weather balloon shifts between for colours to indicate how good or bad the current air quality is, with green being clean air, and red being highly-polluted air. The balloon does not sense the air pollution itself, but uses data from a local air quality organisation and can be seen from up to twelve miles away.
It seems like a very good idea to show people what the up-to-the-minute air quality is like, but will it convince people to alter their plans on the spot and walk, instead of driving?
