A boat having an electric motor coupled with an electrical store is disclosed. The electrical store includes a storage element, and positive and negative poles in current-conducting connection with the storage element. An isolating circuit element is operatively connected to a user activatable emergency stop switch. The isolating circuit element is configured to, upon activation of the emergency stop switch, isolate the current-conducting connection between the storage element and at least one of the poles.

A method for capturing energy from an oscillating object, in which at least one unbalanced rotor is oscillated to rotate the rotor(s) while reciprocally pivoting each of the rotor(s) about a respective counter-oscillation axis that is substantially perpendicular to both a rotation axis of the rotor and the oscillation axis for the oscillating object. Reciprocally pivoting the rotor(s) about the respective counter-oscillation axis urges the rotor to rotate continuously instead of reciprocally, and energy from rotation of the rotor can be captured, for example mechanically or electrically. Optionally, the counter-oscillation axis may be moved to maintain the counter-oscillation axis perpendicular to the oscillation axis for the oscillating object.

A mobile power station for the purpose of recharging electric vehicles is provided. The charging station includes separate, but different, types of electrical generation capabilities. For example, the charging station may include two or more of: wind power, solar power and power generated from suspension mounted oscillators, which charge its battery pack over land. If desired, the mobile power station can be amphibious, as well, with the ability to navigate small and large bodies of water.

An oceangoing vessel exhaust pipe coupling used to temporarily couple to an oceangoing vessel exhaust pipe. Installation and removal of the coupling only requires a simple mechanism with three translational degrees of freedom and one rotational degree of freedom, thereby enabling remote coupling. The coupling adapts to a wide array of exhaust pipe shapes and sizes. This is accomplished by a unique shape that allows stable and balanced resting position on top of an exhaust pipe as well as a two-chamber configuration, wherein the two chambers are separated by a permeable partition. Furthermore, the unique shapes of the chambers deflect the exhaust gas stream towards the outlet of the coupling, regardless of exhaust pipe style, thereby increasing capture efficiency and extending the life of an attached fabric flexible hose.

A gyroscopic roll stabilizer includes an enclosure, a flywheel assembly, a bearing, a motor, and a bearing cooling circuit. The enclosure is mounted to a gimbal for rotation about a gimbal axis and configured to maintain a below-ambient pressure. The flywheel assembly includes a flywheel and flywheel shaft. The bearing rotatably mounts the flywheel assembly inside the enclosure for rotation about a flywheel axis. The bearing has an inner race and an outer race. The inner race is affixed to the flywheel shaft, and the outer race is held rotationally fixed relative to the enclosure. The motor is operative to rotate the flywheel assembly. The bearing cooling circuit is configured to transfer heat away from the bearing by recirculating cooling fluid along a closed fluid pathway. The gyroscopic roll stabilizer is configured to transfer heat away from the inner and/or outer race of the bearing to the cooling fluid.
