It was the first time an aircraft circumnavigated the earth without fuel. After a flight of 43,000 kilometres, “Si2” landed back in Abu Dhabi on Tuesday 26 July 2016, from where it took off in early 2015.
A huge project
The circumnavigation project cost 170 million. With this undertaking, initiator Bertrand Piccard was not suggesting that airliners could today be converted to solar energy, but was aiming to increase society’s awareness of renewable energies. And of what is possible with them – that is, chug around the earth in a non-insulated carbon prototype travelling at 50 to 70 kilometres an hour.
It was hard work and at times risky, but it is possible to travel sustainably in this way. An aircraft such as the “Si2” can (in good conditions) travel for days without landing, being refuelled in the air – with clean solar energy.
The landmark effect of such an expedition is virtually unparalleled and was broadcast all over the world. As a communications agency specialising in sustainability, Polarstern went to work on this with passion and not without pride. For several years, the editorial team of seven followed the events around Solar Impulse, covering it in multiple languages on Bluewin.ch.
