I make cardboard furniture

I created the world's simplest toilets

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

You will make huge savings on water and detergent with our washing machine

I discovered a rich oil field in Tokyo!

I teach empathy with babies

I manufacture fabric out of milk leftovers

I created the Homeless World Cup

I make 100% biodegradable chewing gum

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

Come on over, my neighbour’s making dinner

I created the children's bank

My app helps you make responsible consumer choices

I converted a Boeing 747 into a hotel

I track fake medication

My radio show is run by crazy people

The statues I sculpt weigh only a few grams

I manage the world’s first newspaper for the homeless

we set up schools in the most unlikely places

We transformed a bunker into a hotel
