A group of specially desinged batteries, a robotic arm and new sensor networks are joined to on-site wind generation or other renewable energy generation method that will allow grain elevators in small communities to create affordable, reliable power available to their central city business locations. The use of existing grain silo space to protect and concentrate the batteries creates the opportunity for inconsistant power to be used and stored as reliable supply, without long transmission lines. The battery design requires size and shaping consideration along with the electrical connections in unaccessable areas. Used batteries can be reconditioned or used for other less intensive ...

Seabreath is a device for producing energy from wave motion that improves the performance of the OWC (Oscillating Water Column).

This floating system can also be adapted to fixed installations like jetties or attached to other floating structures. Its particularity than other wave energy converters, that take advantage of the oscillating water column, is to produce a continuous and unidirectional air flow and optimize the exploitation of the wave with maximum simplicity of the structure.

Designed for industrial energy production, the system can also be put to domestic use with a structure that can be easily inserted in the environment.

Its compatibility with the environment, versatility, and constructive simplicity are matched by efficiency in performance worthy of a true ...

Energy Generating Autonomous Sailing Craft (EGASC), unlike other wind energy conversion technologies requiring high stress resisting materials, generates pneumatic air/oxygen compression and electricity by the fast kinetic movement of the planing sailing craft with much higher components reliability.

EGASC moves with the wind and has ability to find and follow
the most favorable wind conditions in the ocean.

For maneuverability, the EGASC has small submersible electrical motors attached on the sides of the hull. Maneuvering and navigation are controlled by a computer program residing in the System Computer and actuated by side steering motors and a servomechanism that positions the single sail.

With EGASC’s proprietary turbine design, the power of 2-3kW of electricity can be obtained and dedicated to ...

Scientists throughout the world are looking for alternate and renewable energy sources due to the rapid decline in fossil fuel deposits. Global warming due to CO2 emmissions from burning hydrocarbons has alarmed some industrialized nations to impose new regulations and taxes to control CO2 production.

It is necessary to maximize the efficiency of energy use in every application untill new energy sources are found. The description below explains the operating priciple of "Jayanada Stove" that recovers part of the energy radiated or wasted from fireplaces. (The same principle can be used to recover thermal energy from exhaust pipes of staionary engines and furnaces, etc.)
ThermoElectric Generators (TEGs) produce Direct Current (DC) and voltage depending on the temperature difference between ...

A new method to obtain electrical energy is proposed. It is based on the use of the energy of an oscillating pendulum. As its movement is slowed by the friction with air, the innovation is the presence of a "drag-compensation system" that acquires energy from wind, as described in the figure 1 attached. A mass m (1) oscillates (3) in a shaft (2) by starting its movement from the rest, at an angle with the vertical axis. The shaft is around a base (4) and connected to an electrical generator (5), that transforms the mechanical oscillation into electrical energy to some station or town, indicated by the arrow. Small wind turbines are placed on the top (6), or elsewhere, ...

The Energy/Power system is an Axial Flux Generator, which is driven by a DC Brushless Motor, intermittently pulsed and running at high rpm's. The rotors are spun as a flywheel by the motor and are embedded with neodymium magnets that pass over copper windings, and produce electron flow through the coils. There have been additional modifications to the system in the form of magnetic bearings for increased performance and the addition of microchannel plates for electron multiplication.

All in all, the Energy/Power system(EPS) is the future technology to create all the Energy/Power required for Individual/ Commercial requirements. The power system is designed to advance the development and implementation of electric vehicles without the constraints of external resources.

Once the ...

The Trekr Design Erosion Control Mat © is made from discarded tires. The tires are cut in half along their circumference as one cuts a bagel in half. These are then joined in groups of seven by the use of stainless steel staples or hog-rings. The grouping in sevens creates a hexagon shape that can be joined to others as in a honeycomb pattern. This product solves two problems at the same time. It provides an excellent erosion control mat that will provide years of service at the same time as it reduces the number of discarded tires that are clogging our ...

In the future, whole fields of solar systems will become increasingly important for electrical power generation. The question is where best to build such solar systems. Ideally, where there is plenty of sunlight. In development and test are solar plants in deserts. There are two challenges, however. On the one hand, the electrical current from the wilderness into civilization by long power lines, which leads to losses. The second problem is dust storms that cover the solar systems with sand and thereby cause malfunction.

Here, a floating solar-system is introduced. It can be set on the water at a coast, e.g. around an existing wind turbines park that is used for anchoring of the solar-array as well. The solar-array ...

In most geothermal reservoirs, i.e. North German Basin, fluid flow is mainly controlled by the permeability of fracture network. Permeability of an individual fracture is proportional to the cube of its aperture, and fractures that form their own pathways are mostly vertical. In this study, dip-slip fault, to be more specific, shear fracture with a rotation angle less than 90° is applied. The fracture is not fully opened yet filled with fluid and possesses high permeability, therein behaves like equivalent porous media. Darcy’s Law is applied to porous media and the fracture. Cubic Law is applied to the fracture.

In this study, an idealized geothermic scenario is simulated with a 2D fundamental numerical model, which is developed using COMSOL ...

We all know that in today’s time everyone is struggling for fuel, and governments of every country is giving instruction to save fuel. To save fuel I am displaying a design of A C generator which will run without fuel.

In this generator I used the concept of REPULSION OF THE SAME POLES OF THE MAGNETS. I observed that both attraction and repulsion of the magnets can make another piece of magnet move so I arranged a series of magnets with a similarity that same poles will in a side (inside or outside like in the figure south poles are inside towards the centre) and there will be two more magnets and it will be attached with the shaft ...
