3D model of the AT monoxylon. The AT monoxylon was inspired by Gary Sloat's dragonfly. It is human-powered, using pedals and an arm crank, and also has a electric motor and car battery. The electric motor is always connected to the propeller and powers it, even if the powered directly by a human and not from the battery. Wires from a alternator on the pedals (and possible another alternator on a arm-powered axle) go to the battery. Wires from the battery go to the motor. A switch is placed in between allowing the to set it to put the motor on/off and to either mode 1 (where alternators charge the battery, battery powers motor) or mode 2 (where alternators power the motor directly, bypass the battery). The hydrofoils can be rotated out of the water when the battery is not being used (direct human propulsion), this as direct human propulsion may not be sufficient to lift the boat out of the water and the hydrfoils would in this instance only create water resistance.
