I use nature to play turntables

I created the world's simplest toilets

My nets capture water from the clouds

I created Flash Mobs

La Nuit du Clean Tag

We shine a green light on factory emissions

I use the forest judiciously

I opened an arts school for vulnerable children

I transform unsold newspapers into eco-bags.

I invented a machine to dye fabric with vegetable scraps

I invented a shrimp-based bioplastic

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

My solid water makes deserts bloom

I change the lives of Africa's poorest farmers

I purify water with solar energy

I detect cataracts with a mobile phone

I use dogs to sniff out prostate cancer

I created universal eyeglasses

We're bringing light where the sun doesn't shine

I collect your food waste to make compost
