I make cardboard furniture

I created a new recycled and recyclable material

I discovered a rich oil field in Tokyo!

I created the Barefoot College

I invented flexible solar panels

The untouchables I help are no longer destined to clean human excrement

The toys I recommend for children aren’t made by other children

A barking mad workshop! #2

I invented a blood test without needles

My refrigerator works without electricity

I create fuel from algae

I track fake medication

I lower your electricity bill

I created metro maps for the visually impaired

The statues I sculpt weigh only a few grams

I manage the world’s first newspaper for the homeless

My third eye translates colours into sounds

I created the world's simplest toilets

I created an open-source machine to make natural dyes. 

I wash cars without water
