I created a universal language for the deaf community

I'm cooking with solar!

I grow my own clothes

I grow vertical gardens

I’m coming to stay with you

I train rats to detect landmines

I install air-conditioning systems above your head

I reveal the secret life of water

My cardboard books are original and affordable

I make paper from stone

I created the children's bank

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

I transform sacks of fish food into chic shopping bags.

I created a new kind of citizen action

I take the elderly for a ride on rickshaws

I created the world's simplest toilets

I turn water from your toilet into drinking water

I help the colour blind see colours

I put a stop to stuttering in under three days
