Smog-Free-Tower-by-Daan-Roosegaarde_dezeen_468_4
I’ve been loving the sunshine we’ve been having lately because it means I can open up all the doors and windows and give the house a thorough airing. We are very lucky in New Zealand that our pollution levels aren’t too high, but overseas in the large cities it can be unbearable. Which is why I like this story about a tower which purifies a million cubic feet of air in an hour.
