I make cardboard furniture

I photograph thousands of people in the nude

I turn water from your toilet into drinking water

we set up schools in the most unlikely places

I help people save for health care

My radio show is run by crazy people

My invention revolutionises personal mobility

I transform unsold newspapers into eco-bags.

I capture CO2 with micro-algae

I change the lives of Africa's poorest farmers

I wash cars without water

I manufacture fabric out of milk leftovers

I breathe new life into ancestral seeds

I grow the packaging of the future

Relax on my carpet of nails

I created the Children’s Republic to keep kids off the streets.

I'm cooking with solar!

I created a new kind of citizen action

I put your computer to work for a good cause

I manage the world’s first newspaper for the homeless
