Drone presentation - 3D Villa Shamengo

I fight against bride kidnapping

I created a hospital for paralysed people like me

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

My technology reduces shipping emissions 

I detect cataracts with a mobile phone

we set up schools in the most unlikely places

I created the children's bank

We started Homeless Man of the Year

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

I use oyster shells to make paint.

I manage the world’s first newspaper for the homeless

I created the Children’s Republic to keep kids off the streets.

I created a universal language for the deaf community

I put a stop to stuttering in under three days

My invention could save your skin

I invented a shrimp-based bioplastic

I build houses out of hemp concrete

I created the world's simplest toilets

I’m a guerrilla gardener
