Welcome to the Buckminster Fuller Challenge Idea Index, a database of entries submitted to the Buckminster Fuller Challenge. We offer this Idea Index as a source of inspiration and hope, as a trimtab in itself. The goal of the Idea Index is to catalyze and facilitate the support needed to implement truly comprehensive solutions. Every individual or team entered in the Buckminster Fuller Challenge is given the choice to ‘opt-in’ to the Index following the conclusion of the selection process. 159 individuals or teams have participated in the launch of the Idea Index with solutions tackling problems ranging from the energy crisis, hunger, transportation, housing, and everything in between. To ease the search process, projects have been sorted by topic and selection status. Click here for more detailed information about the Idea Index
