I detect cataracts with a mobile phone

I created a soup kitchen for animals

I lower your electricity bill

I launched the first ride-sharing company for seniors

My invention revolutionises personal mobility

I wash cars without water

I turn your dance moves into kilowatts

I can recycle anything you throw away

I created the first medical Facebook

I carry fruit and vegetables in the last mile

I grow vegetables in the heart of the city

I help paraplegics to walk again

I created the first green energy network

Come on over, my neighbour’s making dinner

I invented a shrimp-based bioplastic
