It was a personal dream to have ABB joining our family of partners, as we have exactly the same goal of improving the world by reaching more energy efficiency and saving natural resources of our planet.

Whilst Solar Impulse wants to motivate people to use clean technologies, ABB produces them to bring them on the market. This illustrates how realistic the message of Solar Impulse is. ABB makes it possible for everyone to use electrical power as efficiently as on our solar airplane, and to enable renewable energy and ...

Whilst Solar Impulse wants to motivate people to use clean technologies, ABB produces them to bring them on the market. This illustrates how realistic the message of Solar Impulse is. ABB makes it possible for everyone to use electrical power as efficiently as on our solar airplane, and to enable renewable energy and sustainable transport.

With his background of engineer, André is elated as well. ABB is an ideal partner with its long history and rich heritage of technology innovation and this is exactly what also drives us. During the Official Presentation of Solar Impulse 2, on April 9, ABB will be joining the panel discussion around the topic “Meeting the Technological Challenges”.

By the way, have you noticed our new motto “Exploration to Change the World”? It fits so well with our new partnership.

Bertrand Piccard, Stefan Catsicas (EPFL Research Director, 2003)

Solar Impulse is 10 years old –
but since when?

Since I first had the idea following my round-the-world balloon trip in 1999? Since I met Paul McCready, the pioneer of solar flight, for the first time ? Or since the EPFL agreed to launch a feasibility study? 

Since the collaboration with André Borschberg?  The signature of the first ...

Since I first had the idea following my round-the-world balloon trip in 1999? Since I met Paul McCready, the pioneer of solar flight, for the first time ? Or since the EPFL agreed to launch a feasibility study? 

Since the collaboration with André Borschberg?  The signature of the first partner, which enabled us to get the company off the ground? The first flight?

It’s certainly a little of all of that, but nevertheless it is the 28th of November 2003 that I would like to celebrate with you, who have followed us for so long.

That was the point of no return, the date this absolutely mad dream of going round the world in a solar aeroplane was first announced to the media. That day, André and I burned the bridges that would have still allowed us to abandon the idea, to give up. But once we had made the public announcement, we were condemned to go all the way.

It seems such a long time ago, given that Solar Impulse has accomplished so many firsts in these 10 years: the night flight, the intercontinental flight, the crossing of the USA.

Nevertheless, it was the 28th of November 2003 that was to change our lives, and those of our families, for ever.

On that day, André and I still wore a tie. We had to give that up later, in view of the risk that it would get caught up in the propellors of our aircraft…
