Link to the Show / Show NotesJohn Dwyer started a Minneapolis firm called Shelter Architecture, but his big project at the moment isn't meant to house people. The Clean Hub is a device designed to provide clean water, electricity and toilet facilities for urban slums and refugee camps in poor parts of the world. Dwyer will make a presentation on the Clean Hub at Solutions Twin Cities at 8 p.m. on Wednesday, May 2, 2007 at the Southern Theater in Minneapolis. Tickets are $6.
