The Bubbles water taxi flies above the surface of the River Seine during a demonstration by the SeaBubbles company in Paris, France, September 16, 2019. The SeaBubbles craft is powered by electric motors and its hydrofoil wings reduce the drag on the hull in the water, making it more energy efficient than conventional boats. REUTERS/Gonzalo Fuentes
