A hand-held portable mobile device, and a method of use, to generate electricity to charge mobile devices, such as smart phones, by using the kinetic energy of the user's own exhaling air or a manual pump. The device consists of two units; a blowing tube unit and a coupling generator unit. The generator unit include a mechanical part and an electrical part. The mechanical part comprises a freely spinning hollow shaft driven by the force of the user's exhaled air entering into the shaft and then exiting the shaft from narrow orifices of multiple L-shaped pipes configured on the shaft so that the forceful exit of the air from the pipes creates a reactional force that causes the hollow shaft to rotate rapidly. The speed of the shaft's rotation is then further augmented by coupling gears. The rotational force is transmitted to the rotor of a coupling DC generator inside the housing of the generator unit. The electricity thus produced by the generator can be directly delivered to a connected mobile device to be charged via power outlet. In another preferred embodiment, the produced electricity can be stored in coupling capacitor and/or internal battery incorporated within the generator unit. The apparatus further includes a pressure regulator to limit the air pressure entering the device and a second electric regulator to prevent overcharging.

The upper area of the mast can rotate with the generator and have an aerodynamic profile. They can be installed attached to one end by means of a cable between the two banks of a river, or in a narrowing of the same, or they can be subject to elements or means of fastening consisting of a mast, tree, or with a chain, fixed to the ground. at the bottom of the sea or river. The turbines drive a generator and electrical conduction cables and a security and warning facility are added. The generator is placed between the shaft or end of the turbine and the fastening element or means, or behind the mast, on the opposite side of the turbine. In this case, it carries a ball joint at the upper end of the mast. The mast carries deflector plates that are oriented and direct and increase the flow of water or air towards the turbine.

Systems can be used to harness energy from winds. For example, this document describes scalable systems having multiple wing-like blades that can efficiently convert wind power into electricity and other types of energy.

This invention discloses an improved wind turbine suitable for mounting without a wind turbine tower. The wind turbine is based on a rotor with appropriately selected blades. A nozzle and diffuser in the wind flow increase the amount of wind energy available to the rotor. One or more wind turbines can be grouped together in a common housing. The lack of a wind turbine tower and the general compact design allows the wind turbine to be used in close proximity to or on buildings.

A transitioning wind turbine for land or offshore use having a tower base; a wind turbine tower attached to the tower base; a wind turbine attached to the wind turbine tower having a hub and an outer perimeter with spokes disposed between the hub and outer perimeter; a set of vanes carried by the spokes; a generator configured to engage the outer perimeter of the wind turbine and convert a rotational energy of the outer perimeter into power; a lifting tower having a pivot disposed at a proximal end of the lifting tower; a cable attached between the lifting tower and the wind turbine tower; and, wherein the lifting tower is configured to transition from the upright position to the tilted position as the wind turbine tower transitions between the horizontal position to the vertical position.

Described herein is essentially a high-efficiency, hybrid fluid aeolipile. In operation, this hybrid device is placed in the stream of a moving fluid, preferably air. Energy is extracted from the fluid stream by directing a portion of the stream through and, optionally, around the device. As the fluid flow moves through the device, it is directed into nozzles. These nozzles, which are free to pivot in a cyclical manner, employ the established phenomenon of “nozzle effect” to accelerate the velocity of the air-flow passing through them, which is ultimately ejected from each nozzle tip, producing thrust. This thrust, amplified by nozzle effect, drives the nozzles to pivot around a shared axis. The wind energy, thereby converted into cyclical motion, that may be used to perform useful work, is converted with greater efficiency than is possible in conventional blade-type wind turbines.

It is about an omnidirectional generator apparatus, capable of translating the push of a fluid from any direction in the vertical, horizontal or diagonal plains to rotational movement on a unique axis. This rotational movement can be translated to electric energy by known means.

A high-power generating vortex windmill apparatus of an integrated-type rotor is proposed. The high-power generating vortex windmill apparatus includes a central shaft fence coupled to an outside portion of a rotary shaft to be spaced apart from the rotary shaft, a plurality of boundary fences concentrically coupled to an outside portion of the central shaft fence and arranged to be spaced apart from each other, a circumferential wing of which one end is coupled to the rotary shaft, radially arranged, and coupled to the central shaft fence and the plurality of boundary fences by passing therethrough, a plurality of slipstream rings respectively inserted among the plurality of boundary fences and concentrically arranged, and a slipstream ring support simultaneously attached and fixed to the plurality of slipstream rings, installed such that opposite ends thereof respectively connect an inner boundary fence to an outer boundary fence.

The present invention relates to wind energy and can be used to harvest and convert kinetic wind energy into electricity with higher efficiency.

Wind turbine that improves the efficiency of converting wind energy into electrical energy by implementing mechanical design features which harness the entrainment effect by using main rotor blades that are mounted at some distance from the center axis of rotation to allow airflow to pass through its center and to be accelerated by any means (jet fan for example), thus creating higher velocity lower pressure air stream (according to Bernoulli’s law) behind the wind turbine increasing airflow (entrainment effect) through the main rotor blades.

The invention as claimed is a lift-based horizontal-axis wind turbine, the design of which provides higher performance efficiency by extracting more energy from the airflow and at better coefficient of performance and converting it into electrical energy, compared to conventional lift-based horizontal-axis wind turbines of the same turbine rotor diameter.
