John Dwyer's Clean Hub
John Dwyer started a Minneapolis firm called Shelter Architecture, but his big project at the moment isn't meant to house people. The Clean Hub, pictured at left, 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 and student architects are working afternoons at the University of Minnesota to finish the prototype. When it's ready for market, the Clean Hub will cost around $12,000 and is designed to serve 500 people for 30 years. Dwyer will make a presentation on the Clean Hub at Solutions Twin Cities at 8 p.m. on Wednesday, May 2 at the Southern Theater in Minneapolis. Tickets are $6.
