Dutch artist and designer Daan Roosegaarde has developed a “vacuum cleaner” which uses copper coils to generate an electromagnetic field which would pull airborne particles in smog down to earth for cleaning and disposal. The device is not a cure-all answer
however, as Roosegaarde says he designed the tool to help draw
attention to air pollution in general, and to encourage others to
think creatively about how to solve the worldwide problem.
