I make cardboard furniture

I help paraplegics to walk again

I can recycle anything you throw away

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

I recharge my phone while getting fit

I pioneered farming in a bag

I invented a blood test without needles

I grow my own clothes

Clip Villa Shamengo COP 21

I'm fighting the blood mafia with my free donation network

We're marketing an invasive mollusk as a new seafood option

My invention revolutionises personal mobility

I’m fighting for peace

I turn your dance moves into kilowatts

I change the lives of Africa's poorest farmers

I take the elderly for a ride on rickshaws

I free the mental ill who have been kept in chains

I bring electricity off the grid

Learn to praise yourself

Our students pump fresh water on the playground
