The challenge

Travelling to the edge of the planet using only renewable energy

The aim is to protect our planet’s climate from greenhouse gases by demonstrating that concepts and projects that seemed inconceivable a short time ago are now possible with the technologies available today.

The plane

A team of passionate and highly specialised people

Multi-skilling is a must in such an experimental project. The team consists of a mix of aeronautical engineers, pilots, builders and others.
