Benefit Through Vehicles Passing on Highways in Electrical Power Generation

The turbulent airflow caused by vehicular movement on highways is a source of kinetic energy for wind energy (WE) that can be utilized to power highway lighting and communications. The purpose of the current work is to design, install and measure the extent of benefit from small wind turbines along a Highway (HW) in one of the governorates of Iraq - Dohuk. In this investigation, wind speed measurements are close to a significant HW on the Dohuk-Zakho-Iraq (DZI) Road. The three positional characteristics are examined for the wind turbines' optimal position. These factors are heights above ground level, lateral distances from the road shoulder, and the wind turbines' highway-facing orientation. It is possible to supply electrical power for side lighting of external roads via vertical axis wind turbines (VAWT), which are produced from disturbances in air movement. In addition, a battery pack has been used to store energy to sustain fluctuations caused by stopped vehicle traffic and to ensure load operation in the event of a wind turbine stop. A 500W capacity vertical axis windmill is being worked on. The suggested landscaping technique has generated exceptional and long-lasting effects for a price of under 350 US dollars.

Wind is the movement of air from an area with high pressure to an area with low pressure. Wind energy is one of the many abundant renewable energies. One example of the use of wind energy in Indonesia is the Wind Power Plant. A vertical axis wind turbine is a wind turbine that moves vertically where its axis is perpendicular to the ground surface. The advantage of this vertical axis windmill is that the turbine is not always directed towards the wind. The disadvantage of vertical axis wind turbines is that their efficiency is lower than horizontal axis wind turbines because there is lower wind speed and air resistance. In this article we will explain about vertical axis wind turbines, Wind Power Plants, and how wind turbines work. The research method used in writing this article is the literature study research method by reviewing several articles. From the research that has been carried out, the results obtained are an understanding of vertical axis wind turbines and wind power plants.

The Perceptions and Risk Reduction Strategies of Small-Scale Salt Farmers on Madura Island

Salt farming is considered a risky venture due to the influence of both internal and external factors. Therefore, this study aimed to describe farmers' perceptions regarding the causes, opportunities, and impacts of risks to develop a risk reduction strategy for salt farming in Madura Island. The study used a multistage sampling method to obtain 120 respondents and was conducted in three regencies: Sampang, Pamekasan, and Sumenep. The first objective was analyzed using the descriptive method, while the second was designed using the Kountur method. Farmers' perceptions showed that seawater quality, wind and temperature, rainfall, soil porosity, price volatility, marketing channels, government policies, capital constraints, and human resource quality could cause risks in salt farming. Several risks were perceived to significantly impact salt farming, such as government policies, partnerships, marketing channels, prices, and capital availability. Therefore, some recommendations to improve the risk reduction strategies included the use of horizontal axis windmills, revitalization of groups and partnerships, and capital strengthening through the effectiveness of the PUGAR (Empowerment of Smallholder Salt Businesses) policy by the development of standard procedures for the timely and targeted distribution of the aides.

Design and Simulation of Vertical Axis Windmill for Streetlights

Since 2000, use of wind energy has grown quickly, making it one of the most promising renewable energy sources for power generation. The most appropriate way to categorise wind turbines is according to their orientation, namely as Horizontal Axis Wind Turbines (HAWT) and Vertical Axis Wind Turbines. (VAWT). As technology advances, everyone wants to utilise renewable energy instead of non-renewable resources for a variety of reasons, including the scarcity of fossil fuels and the effects of global warming. We thus sought to create something that is eco-friendly and utilises renewable energy. The wind is forced to both sides of the road while a car is travelling down it. With the aid of wind turbines, we are able to transform this energy. Therefore, our goal is to create a wind turbine that can generate 100 W of electricity. Power generation for the home may be done with vertical axis wind turbines. Depending on the design, VAWT can produce electricity at speeds ranging from 3 m/s to 40 m/s. The main benefit of VAWT over HAWT is that they can catch the wind in any direction since it reduces the expense needed for the yaw gear. Due to its straightforward construction and compact size, VAWT may be fastened to the roadside poles. So, in addition to the regular wind flow, they may also create power using the wind energy produced by moving cars. Although VAWT efficiency is lower than HAWT, they may still be deployed in locations with low wind speeds. Noise pollution and low maintenance characterise VAWT.

The Experiment of Wind Electric Water Pumping for Salt Farmers in Remote Area of Demak-Indonesia

Local villagers in the remote area of Wedung, Demak, northern of Central Java, Indonesia utilized special equipment called wind-pump for sea water lifting and circulating on salt production processes. The salt farmer has skill to produce, manufacture and maintain his own traditional wind-pump. In the windpump structure unit consisted of four blades horizontal axis windmill and reciprocating pump. This experiment study separated both windmill and pump by 50 meters. The pump was low speed centrifugal type pump. The windmill shaft was connected electrically to the pump shaft. The electric transmission components were an AC generator, diodes circuits and an DC motor. The experiment is carried out in a place that has the same characteristics as the original place at southern region of Bantul, Yogyakarta, Indonesia. The variation of experiment was pump head of 55 cm and 85 cm during 6 hours each variation. The average wind speed at the time of data collection at the head of 55 and 85 cm were 3.9 and 3.8 m/s. The volume flow rate and the volume produced by the pump during 6 hours of operation were 0.134 and 0.215 liter/s and 2901.6 and 4640.6 liters.

DESIGN OF VERTICAL AXIS SAVONIUS WINDMILL FOR GENERATING ELECTRICITY USING PERMANENT MAGNET

At present the use of wind energy in Indonesia is still relatively low, but has enormous potential. One reason is because the average wind speed in the territory of Indonesia is classified as low wind speed, which ranges from 3 m / s to 5 m / s making it difficult to produce electrical energy on a large scale. However, the wind potential in Indonesia is available almost all year long, making it possible to develop small-scale power generation systems. Innovations in modifying windmills need to be developed so that in conditions of low wind speeds can produce electrical energy.
 In this research, a prototype was developed by designing a vertical axis windmill power plant model Savonius using a permanent magnet generator, which can produce optimal electrical energy by utilizing relatively low wind speeds.From the generator test it was found that with a rotor rotation of 50 rpm up to 500 rpm can produce an electrical voltage of 0.02V to 10V and an electric current of 0.60A to 4.53A.

Additive manufactured portable vertical axis windmill

ABSTRACTThe vertical axis windmill is a type of wind turbine in which the main rotor shaft is set vertically. The main aim of this is to make it more compatible and accessible. According to the research, there is plenty of enough wind available globally to meet the human energy requirements – if it is harvested on a large scale effectively. If the wind turbine efficiency is increased, then there is a chance for more power generation and to drastically decrease the use of power generators which are rather expensive and also cause pollution. In comparison to horizontal axis wind turbines, the vertical axis wind turbines may be efficient as them and are also cheaper to build and maintain. In this paper, we designed and fabricated a vertical axis wind turbine and fabricated the same using the ‘3D printing technique’ which is one of the additive manufacturing processes used now.

Vertical Axis Windmill

Engineers and environmentalists are pursuing the utilization of renewable energy in lieu of ever the increasing demands for electricity. Our generation has inherited the charge for finding a solution to society’s growing needs. Capturing wind energy was first conceptualized in 1888 by Charles. F. Brush, and has evolved into large scale wind turbines and generators known today. However, a small scale system for exploiting wind energy has eluded mass production, when it could realistically be implemented into our everyday lives. Through our daily tasks, society loses kinetic energy to the environment; a small scale wind turbine will streamline energy efficiency from a renewable source. Our goal is to design a propeller that will suit an aesthetic residential sized wind turbine that will perform well in a non-commercial environment and be easy to expand to a whole system.

Conceptual Design of Innovative Eco-Friendly Windmill

A wind turbine performs the function of converting the energy (kinetic) derived from the wind into another form of energy (mechanical) which is employed for the purpose of driving the generator which in turn generates electricity from this mechanical energy. The most common types of windmills employed in practice include horizontal and vertical axis wind mill. These windmills are fabricated in different structures for producing electricity. The main objective of this paper is to design an innovative eco friendly windmill to overcome the various difficulties existing in conventional windmills. In conventional windmills, the propeller rotation depends on the velocity of wind flow in the environment. But in this paper, we have fabricated an innovative eco friendly windmill in which, the propeller rotation is increased four times for the wind velocity in the surroundings.

Methodology for the design of energy production and storage systems in buildings: Minimization of the energy impact on the electricity grid

Human life requires energy. Moreover, people spend around 90% of their time in buildings while about 40% of primary energy needs are due to buildings. That is why the present paper deals with a methodology allowing identifying and assessing the energy impact of a building on the electricity grid. Thanks to both the building models we developed and fuzzy logic contribution (used to control ventilation and develop occupancy scenarios related to human habits and lifestyle), the results we obtained in simulation validate the proposed impact indicator. Different insulation levels were considered as well as energy production (solar photovoltaic and thermal panels and a vertical axis windmill) and storage (a domestic hot water tank) systems. These results highlighted the pertinence of such an indicator for optimizing the design of the just-mentioned systems and minimizing the amount of energy exchanged by buildings and the electricity grid. One can promote energy injection or take into account the status of the electricity grid when designing these systems. As a key result, the produced renewable energy is partially self-consumed, what allows for a more efficient and rational use of energy in buildings.
