A belt, preferably for use in a device for rotor blade adjustment on a wind turbine, includes a base body made of polymeric material and at least one strength member made of metallic material, which is embedded in the base body and running in the longitudinal direction. The belt has a first surface and a second surface situated opposite the first surface, in which at least the first surface has a reinforcing fabric. The belt has at least one sacrificial anode made of a metallic material, in which the metallic material is less noble than the metallic material of the strength member.

A remote control system for an aircraft includes an aircraft of the Magnus-effect type. The aircraft includes a cylinder extending along a longitudinal axis. The cylinder is able to rotate about the longitudinal axis. A pair of rotatable are arranged at a distance from the aircraft. A drive means is designed to drive a rotational movement of the pair of rotatable elements. A connection cable is arranged to connect the pair of rotatable elements to the cylinder of the aircraft in such a way that the rotational movement of the pair of rotatable elements, driven by the drive means, is mechanically transmitted to the cylinder of the aircraft so as to cause the cylinder to rotate about the longitudinal axis.

The present invention is directed to a system for producing energy via use of gravity. The system is for generating energy, and in particular electrical energy, by utilizing the abundant force of gravity that exists and then integrating such a force into a system design of energy power generation by converting the force of gravity into potential energy then into kinetic energy and from kinetic energy back into potential energy again, by using the system's autonomous methodology of fluid recycling to produce electric power generation in the process.

A mass displacement electricity generator, having a tower and a first mass suspended by the tower for falling and lifting. The first mass is suspended by a pulley arrangement including a first set of pulleys fixed to the tower above the first mass and a second set of pulleys fixed to the first mass. A cable extends through the first and second sets of pulleys and one end of the cable is fixed to one of the tower or to the first mass. A winch includes a barrel about which the cable winds off as the first mass falls and winds on as the first mass lifts. The winch is in driving connection with a flywheel so that as the first mass falls, the cable winds off the barrel and barrel rotation drives the flywheel to rotate. The flywheel is in driving connection with a generator so that rotation of the flywheel drives the generator for generating electrical energy.

Systems and methods related to linear turbine systems are presented. Each embodiment described herein may be designed as a single-stage, linear, impulse turbine system. In an embodiment, a linear turbine includes a first shaft extending along a first axis; a second shaft extending along a second axis, the second axis being separated from and substantially parallel to the first axis; a first plurality of buckets to travel a first continuous path around the first shaft and the second shaft along a first plane, the first path including a first substantially linear path segment between the first axis and the second axis; and a nozzle configured to direct a first fluid jet to contact the first plurality of buckets in the first linear path segment.

The present invention is a system for producing energy via use of gravity and then integrating such a force into a system design of energy power generation by translating the force of gravity into potential energy then into kinetic energy and from kinetic energy back into potential energy again. This system can operate mechanically or electromechanically with the aid of a minimal amount of external energy. A mechanical sequence is introduced in the system's operation to prolong the operational functionality of motion to its working components to the point where full, or substantially full, and independent recycling of fluids takes place and in the process it generates power to run the system's electricity producing generators and supply electricity to the power grid.

The present invention is a system for producing energy via use of gravity and then integrating such a force into a system design of energy power generation by translating the force of gravity into potential energy then into kinetic energy and from kinetic energy back into potential energy again. This system can operate 100% mechanically or 100% electromechanically by its own power generation, without the need to utilize the aid of an external source of energy or, if required, with the aid of a minimal amount of external energy. A mechanical sequence is introduced in the system's operation to prolong the operational functionality of motion to its working components to the point where full, or substantially full, and independent recycling of fluids takes place and in the process it generates power to run the system's electricity producing generators and supply electricity to the power grid.

A mechanical machine containing water in three tanks in its entirety, represented by a tank fixed at the top of the machine and not moving, and a tank moving up and down in the middle of the machine, and a tank moving up and down at the bottom of the machine. The movement of the middle and lower tank periodically tries to transfer water to the upper tank through five stages through its interaction with the remaining main parts of the machine (for example, gas springs, large water injections and automatic mechanical braking system).
