My technology reduces shipping emissions

A barking mad workshop! #2

I build houses out of hemp concrete

I created Clean Up Day

I pioneered farming in a bag

I can recycle anything you throw away

I track fake medication

Learn to praise yourself

I make edible food packaging

I recycle plastic bags in New Delhi

I help people save for health care

I pay you back for recycling

I created universal eyeglasses

I wash cars without water

I invented a shrimp-based bioplastic

I make paper from stone

I recycle rare earth metals

I detect cataracts with a mobile phone

I free the mental ill who have been kept in chains

My refrigerator works without electricity
