I make cardboard furniture

I invented a blood test without needles

Clip Villa Shamengo COP 21

I created the world's simplest toilets

I use ducks instead of pesticides in my rice fields

My works exist in harmony with the natural world

My cooker lets nothing go to waste

I photograph thousands of people in the nude

My couriers are deaf and mute

I use hypnosis for surgical operations

I save lives with mobile phones

My electric bike runs on hydrogen

I make 100% biodegradable chewing gum

I bring sunlight to those forgotten by development

I converted my city to vegetarianism

I make soap from used cooking oil

I created a network of solidarity supermarkets

I free the mental ill who have been kept in chains

I can recycle anything you throw away

We're providing potable water to those in need
