Environmental action: an air-cleaning tower turns fine dust into jewels

A Dutch artist, Daan Roosegaarde, has developed a tower of seven meters that is supposed to clean the air of Rotterdam starting this week. Fine dust particles accumulate in the tower and are subsequently compressed in the form of a jewel. This jewel is sold as a ring in order to finance the project.
