The water-powered motor has been a sacred goal of the car business since the steam-controlled carriage — a thought that has been generally overlooked with the ascent of electric vehicles. Designer Maxime Lefebvre was recruited by Yamaha to plan a water-controlled bike, and now the official pictures are here. The motor uses a “shut circle” water siphon to constantly cycle water, like how inside ignition motors work with touchy fluids. What controls the siphon isn’t known, yet a decent theory would be a battery-powered battery. Lefebvre‘s plan takes motivation from the 1975 Yamaha XT, a bicycle that would proceed to win the Dakar Rally. Look at Lefebvre’s Behance for more data and ideas.
