The invention relates to the field of energy, and more specifically, to wind power plants that generate electrical energy by using air flow force. The wind energy conversion module comprises a casing configured to move along the guide belt, including installed in a casing, at least, one wind energy receiver in the shape of a kite mounted on the casing, an orientation drive of the wind energy receiver relative to the wind and the casing, a control system, as well as an electricity generator configured to generate electricity when the casing moves along the guide belt and at force interaction with the contact guide rail associated with the guide belt. The control system is configured to change the modules speed by changing the braking force of the electricity generator. The invention allows to ensure a high wind energy efficiency by controlling the modules speed.

A barge for renewable energy recourses is disclosed that comprises a plurality of horizontal axis wind turbines, a plurality of photovoltaic panels; and a plurality of sea-wave generators. The energy harvested by the renewable energy recourses is transformed to electrical energy and the electrical energy is transmitted to a grid onshore. A fleet of a plurality of barges located in deep waters is disclosed as well.

An apparatus converts mechanical energy to electrical energy. The apparatus includes a linear electrical generator. The linear electrical generator includes at least one translator with translator poles and at least one stator with stator poles. The stator poles are aligned with the translator poles according to a Vernier scale. For given lengths of the stator and translator, the number of stator poles in the stator is offset by an integer number of translator poles in the translator.

A Vernier permanent magnet linear generator employs a translator having a plurality of translator modules oriented in a vertical array. At least a portion of the plurality of translator modules has permanent magnets. Supports at lateral edges of the plurality of translator modules and a rod connected to the supports attach the translator to a driving element. The driving element reciprocating the translator in a longitudinal direction. Two stators are supported on a reaction body oppositely spaced from the vertical array of translator modules by an air gap and offset by one half slot pitch. The stators have three phase integral-slot stator windings magnetically interacting with a magnetic field induced by the permanent magnets. A slot depth of the stators is configured such that an 11.sup.th harmonic component of the magnetic field is saturated at a multiple value of a 1.sup.st harmonic component.

An apparatus that floats at the surface of a body of water over which waves pass, causing a nominally vertical axis of the apparatus to tilt away from an axis normal to the resting surface of the body of water. Tilting allows a fluid to flow through a channel that in an un-tilted apparatus would require the gravitational potential energy of the fluid to increase (i.e., to flow uphill), but, because of the tilt allows the fluid to flow through the channel in a downhill direction. Successive wave-driven tilts of the apparatus incrementally raise water to a head from which a portion of its gravitational potential energy can be converted to electrical power by causing the water to return to a lower level by flowing through a water turbine, or through some other apparatus that performs a useful function when supplied with a flow of high-pressure water.

A hybrid energy harvesting system for powering underwater vehicles having at least one thermal engine, at least one of a solar or a wave energy harvester, and a battery which stores electric energy produced by the harvesters. The energy harvesters keep the battery charged and thereby expand an underwater vehicle's operational areas to high latitudes and shallow water. Multiple thermal engines employing different phase-change materials can be used to expand the vehicle's working temperature range and thus allow it to operate over a larger area. An electric motor powered by the battery and a pump driven by the motor can be used to pump hydraulic fluid between the accumulators and external bladders of the thermal engines to cause the vehicle to descend and ascend when the thermal gradient to which the vehicle is subjected is insufficient.

Systems and methods for use in capturing energy from natural resources. In one form, the systems and methods capture energy from natural resources, such as movement of fluid in a body of water, and convert it into electrical energy.

The Buoyant Synchrony Actuated Inductance AC Generator is a Wave Energy Converter using marine energy from Wave Power and converting it to Electricity. The entire Converter comprises of numerous sub-generators operating independently within its self.
