Been thinking of ways to save the planet?
So have this group of designers, architects, activists, entrepreneurs, artists, and planners from around the world who have been working on solutions to some of the globe’s most vexing problems.
Their proposals—20 in all—have been named semifinalists in the Buckminster Fuller Institute’s 2014 Fuller Challenge. The contest searches for the best strategies for addressing a pressing global issue, ranging from sanitation, health, food, and poverty to water systems, conservation, and design.
The Fuller Challenge judges look for ideas that can be applied globally. The first-place winner takes home a $100,000 prize.
The award is named after the inventor and neo-futurist architect Buckminster Fuller, famous for his geodesic domes and distortion-minimizing world map—outside-the-box ideas that are the inspiration for today’s challenge.
We’ve highlighted five of the most intriguing ideas.
