Try designing a filter system for pulling pollution out of the air for major cities. It has too use very little power(maybe solar) and go on the top of large buildings in the city to reduce pollution.

The filter needs to be able to be cleaned and reused.

Always wanted to work on this, but never get the time.

Hope you can come up with something. It could make a fortune for someone who can make it work and be affordable.

Good luck!
