adventure PlanetSolar with a value of 77 centimes Euros representing PlanetSolar in Monaco. SolarStratos SolarStratos is a project officially begun in March 2014 by Raphaël Domjan. It is a two-seater solar plane built by Calin Gologan. Raphaël Domjan plans with his team to achieve an absolute altitude record. The SolarStratos mission should allow Raphaël Domjan to reach the stratosphere at more than 18,000 meters, an altitude never reached with a conventional propulsion aircraft. According to SolarStratos, this project would aim to demonstrate that renewable energy makes it possible to go beyond what is possible with conventional propulsion methods. The SolarStratos aircraft was unveiled to the public on 7 December 2016. Ultimately, and after the record flight planned from 2024, Raphaël Domjan and the SolarStratos team wish to commercialize the technologies developed during the stratospheric mission, in particular by developing stratospheric solar drones.
