The idea and the prototype of electric boat with solar energy recharge are by Marco Musu. He used the robotic arm with the cutter and made the hull in high-density polystyrene. The boat has 5 speeds and the maximum speed supported 4h. #electricboat #batteryboat #solarboat https://www.instagram.com/p/B3U-249FVOz/?igshid=1ge54h5g296mp
