Drone presentation - 3D Villa Shamengo

I recycle plastic bags in New Delhi

I created the Homeless World Cup

I invented a machine to dye fabric with vegetable scraps

I make you laugh out loud

I created the world's simplest toilets

I created the world’s largest work of art made from recycled objects

Our students pump fresh water on the playground

I trade your trash for organic food

I created a hospital for paralysed people like me

I created the Barefoot College

I construct photovoltaic greenhouses to combine green energy with organic farming

A barking mad workshop! #2

We started Homeless Man of the Year

My cardboard books are original and affordable

My radio show is run by crazy people

I protect gorillas from coltan miners

I created a new kind of citizen action

I created the children's bank

I created a deodorising fabric with coffee grounds
