The authors Ed van Hinte and Conny Bakker set out to violate fixed ideas like: wood is sustainable and plastics are wrong. The book is based on workshops organised by the o2 network of environmentally conscious designers who believe that dealing with environmental problems can be fun as well as viable. Four chapters about space, transport, electronics and food contain projects and ideas that invigorate and inspire. Breathable food, road asphalt for solar energybatteries and a hand powered mobile phone jostle next to design case studies for these, as yet, imaginary products.
