I use nature to play turntables

I created a hospital for paralysed people like me

I created the world's simplest toilets

We created a seventh heaven on the Internet

I created a universal language for the deaf community

I created the first green energy network

Relax on my carpet of nails

My radiator is inspired by the sun

I make bioethanol from your old clothes

I save lives with mobile phones

I change the lives of Africa's poorest farmers

I created the zero waste festival

Our drivers tackle some of Africa's toughest roads to save lives.

I make edible food packaging

I’ve created a bamboo laminate that’s cheaper than plywood

I cross oceans in a boat made of jute

I offer a roof to millions of people

I’m reducing crime with urban planning

I created a deodorising fabric with coffee grounds

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