An electric generating system uses a zeppelin filled with helium or hydrogen, and a spinnaker sail, to provide pulling power that will lift a heavy railcar to an elevated height on a track, such as on a hill or mountainside, or in an elevator-type shaft in a tall building. When the heavy car reaches the top of the track, it is released, and its descent drives an electric generator. The generator can be carried by the car, and can send the power to batteries on the car, or to conductive rails. Alternately, if the car is inert weight, cables can drive stationary generators. The zeppelin will be inflated and deflated repeatedly, using equipment to recapture energy during each gas expansion, to help drive subsequent recompression into high-pressure tanks. The spinnaker sail will use a cable-handling device and spreader bars to deploy the sail and keep it at an elevated height. Various advantages are provided compared to wind turbines and pumped-storage hydroelectric facilities.

A brake mechanism (10) for an elevator (2) is activated in response to an electronic control signal to prevent movement of an elevator car (16) under predetermined conditions. The brake mechanism is preferably a safety mechanism (10) and does not require a governor sheave, a governor rope, or a tension sheave. The safety mechanism in one disclosed example utilizes a solenoid actuator (22b) and an electric motor (40) and gear box assembly (42) to move safety wedges (18) into engagement with a guide rail (20) to stop the elevator car (16). The safety wedges (18) are held in a non-deployed position during normal elevator operation. If there is a power loss or if elevator car speed exceeds a predetermined threshold, an electronic control signal activates the safety mechanism (10) causing the solenoid to release, which causes the safety wedges (18) move in a direction opposite to that of a safety housing (12) mounted for movement with the elevator car (16). Angled surfaces of the safety housing (12) force the safety wedges (18) into engagement with the guide rail (20). The safety mechanism (10) can be selectively reset from a remote location.

A method of aircraft propulsion and control more specific to rotorcraft propulsion and control using forward, neutral and aft thrust in addition to forward / aft thrust coupling from the propulsive tail assembly through cyclic and collective pitch of the non-flapping, ridged propeller / fan blades and / or from a turbojet / turbofan vectored thrust system. The cyclic blade pitch induces a drive shaft bending moment that is used to provide aircraft directional control and also provides anti-torque control for a single rotor head helicopter. The forward / reverse collective thrust actuator, phase lag elevator effect cyclic actuator and phase lag rudder / anti-torque effect cyclic actuator do not require complex control mixing. The vectored thrust system also provides aircraft directional control and anti-torque control individually or combined with the propeller / fan assembly. This assembly eliminates the requirement of rudder or elevator control on a fixed wing aircraft and the requirement of a tail rotor on a conventional helicopter while increasing speed and maneuverability. A slowed or stopped ridged X-wing rotorcraft hub with a modified circular arc airfoil would not require cyclic / collective control.
