My technology reduces shipping emissions 

I doubled green space by building a hotel

These wood bricks don't need nails, screws, or glue

I restore women who have been destroyed by rape

I fight against bride kidnapping

Learn to praise yourself

I install air-conditioning systems above your head

I detect cataracts with a mobile phone

I created the children's bank

I discovered a rich oil field in Tokyo!

I’m a guerrilla gardener

I created a new kind of citizen action

I created the world's simplest toilets

I use ducks instead of pesticides in my rice fields

I’m fighting Michael Jackson’s disease

I purify water with solar energy

I’ve pioneered diaper recycling

I make paper from stone

My invention revolutionises personal mobility

I transform milk bottles into designer lighting
