I make cardboard furniture

I reveal the secret life of water

I use the forest judiciously

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

My invention revolutionises personal mobility

The statues I sculpt weigh only a few grams

I purify water with solar energy

I created metro maps for the visually impaired

I created a deodorising fabric with coffee grounds

I doubled green space by building a hotel

I created the world's first solar cycle path

My cardboard books are original and affordable

I breathe new life into ancestral seeds

I created the world's simplest toilets

I pay you back for recycling

I help the colour blind see colours

I save lives with mobile phones

My works exist in harmony with the natural world

I launched the first ride-sharing company for seniors

My technology reduces shipping emissions
