I created a universal language for the deaf community

I wash cars without water

I’ve pioneered diaper recycling

I cross oceans in a boat made of jute

I co-created the world’s first chain of eco-hotels

I converted a Boeing 747 into a hotel

I build houses out of hemp concrete

I grow vertical gardens

I support AIDS victims until their last breath

Our ‘hives’ give you access to farm-fresh products for less

I bring sunlight to those forgotten by development

I make cardboard furniture

I invented flexible solar panels

I manage the world’s first newspaper for the homeless

I bring light slums with our old plastic bottles

I make you laugh out loud

I help cheetahs reproduce

I invented a sail to power cargo ships

I created the world's simplest toilets

I created the Homeless World Cup
