Planet Solar in Brisbane


The initial objective of the PlanetSolar adventure was to demonstrate, through the success of the first world tour completed using exclusively solar energy, that today, we have the resources, the knowledge and technologies required to reduce our dependence on fossil energy.

From the conceptualisation of the project, the principal investor and owner of the boat Immo Stoeher wanted, after completing her world tour, to give the vessel a second “useful” life.

Since the success of the world tour, PlanetSolar has put this vision into practice and now operates the solar vessel for practical purposes. As both a communication, scientific or even educational platform, the vessel is now moving beyond her role as mobile ambassador for photovoltaic energy and is becoming a multifunctional tool just like the “Swiss army knife”!
