I created a universal language for the deaf community

I created universal eyeglasses

I use plants to clean toxic soil

My restaurant runs on hydroelectric energy

I build houses out of hemp concrete

Trade your steak for bugs!

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

I cross oceans in a boat made of jute

I make soap from used cooking oil

I save lives with mobile phones

I teach empathy with babies

I created the children's bank

I'm building sustainable earthen roofs

I keep women off the streets by training them to be mechanics

I capture CO2 with micro-algae

I help the colour blind see colours

I change the lives of Africa's poorest farmers

I created a foldable electric car

I offer gourmet dining to the poor

I grow mushrooms from your coffee grounds
