I make cardboard furniture

I created the world's simplest toilets

I created a deodorising fabric with coffee grounds

I rent out my goats to mow your lawn

I install air-conditioning systems above your head

My radio show is run by crazy people

Clip Villa Shamengo COP 21

I manufacture fabric out of milk leftovers

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

I fly with migrating birds

Trash from the sea is treasure for our art

I created the Barefoot College

I help cheetahs reproduce

I discovered a rich oil field in Tokyo!

I transform sacks of fish food into chic shopping bags.

I converted my city to vegetarianism

I train rats to detect landmines

I can recycle anything you throw away

I launched the first ride-sharing company for seniors

I use oyster shells to make paint.
