My technology reduces shipping emissions 

I'm cooking with solar!

I help paraplegics to walk again

I created the world's simplest toilets

I doubled green space by building a hotel

We started Homeless Man of the Year

I detect cataracts with a mobile phone

I invented a blood test without needles

My pencils make plants growing

I created the Barefoot College

Come on over, my neighbour’s making dinner

I created a hospital for paralysed people like me

I created a deodorising fabric with coffee grounds

I harvest thistles to make bioplastic

I heat your apartment with computing power

I use oyster shells to make paint.

I launched the first ride-sharing company for seniors

I bring electricity off the grid

My refrigerator works without electricity

I fill up my tank with what you throw away
