The Playa de la Ribera de Baiona (Pontevedra) hosted this Saturday the 6th edition of the Solar Boat Challenge organised every year by Marine Instruments. The appointment with technological innovation and youth, in which SusTunTech collaborates every year, got the beach to be populated by 300 young people from different corners of Spain, in a competition that promotes scientific concerns among schoolchildren, always with the interest and support of their mentors.
