I created a universal language for the deaf community

I offer a roof to millions of people

I lower your electricity bill

Coral reefs have a future because of my invention

We started Homeless Man of the Year

I grow vertical gardens

I created Neighbour Day

I use ducks instead of pesticides in my rice fields

I put a stop to stuttering in under three days

I grow vegetables in the heart of the city

I’m reducing crime with urban planning

I protect gorillas from coltan miners

I invented a machine to dye fabric with vegetable scraps

I change the lives of Africa's poorest farmers

Come on over, my neighbour’s making dinner

I invented flexible solar panels

I manage the world’s first newspaper for the homeless

I converted a Boeing 747 into a hotel

I created a deodorising fabric with coffee grounds
