Micro URBAN Wind Energy Solution

Introduction

EW Turbines multi-blade vertical axis micro wind turbine addresses the unique challenges and opportunities presented by urban environments. With increased urbanisation and the expansion of contemporary transportation networks, new sources of wind energy have emerged that can be harnessed for sustainable power generation.

Innovative Turbine Design

The turbine features a multi-blade vertical axis structure, optimised to capture and utilise wind speeds commonly found within cities and transit corridors. Unlike traditional wind turbines, this design specifically leverages urban wind phenomena such as down draughts and corner acceleration effects, which are frequently encountered in built-up areas. Additionally, the turbine targets wind flows generated by highspeed and commuter electric trains, which produce reliable and consistent air movement.

Harnessing Urban Wind

Urban environments and transit corridors present unique wind patterns resulting from architectural layouts and transportation activities. EW Turbines’ solution is engineered to take advantage of these wind flows, including the effects of wind interacting with buildings and street corners and those created by passing trains. By focusing on these predictable sources, the turbine can generate micro-scale energy efficiently within urban environments.

Practical Approach for Built-Up Areas

Targeting these reliable and consistent wind flows, EW Turbines technology is a practical approach to energy generation in urban settings. The innovative technology is tailored to the growing demand for sustainable energy solutions that integrate seamlessly with existing infrastructure, making it suitable for deployment in a variety of built-up environments.

EW Turbines Micro Wind Turbine: Advanced Features and Urban Suitability

Self-Starting Savonius Concept

At the heart of the turbine’s operation is its self-starting Savonius concept. This allows the turbine to initiate rotation even when wind speeds are very low. Such capability ensures the turbine remains effective in locations where consistent wind flow cannot be guaranteed, making it an ideal solution for urban and transport corridor applications.

Patented S-Shaped Blade

The S-shaped blade delivers higher torque output while simultaneously reducing aerodynamic drag and providing lift. Efficiency across a broad range of wind conditions is enhanced compared to other turbine designs, contributing to reliable performance in challenging environments.

Interlocking Blade

Interlocking blade assembly provides strength and rigidity, enhancing overall durability ensuring long-term reliability and consistent operation.

Lightweight, Low Cost Production and Easy Installation

Injection moulding utilising lightweight, fibre-reinforced composite materials result in a robust turbine that is simple to install. These materials contribute to the system’s resilience while allowing for ease of handling and deployment in a range of environmental settings.

Direct Drive

Direct drive technology eliminates the need for complex transmissions. Minimising mechanical energy loss ensures maximum wind energy is converted to electrical power.

Omni-Directional Operation

Omni-directional operation eliminates the requirement for yawing mechanisms, enabling capture of wind from any direction, an essential feature for urban environment deployment where wind direction frequently shifts.

Low Noise Emissions

Operational noise levels are within the low range between 15 and 65 decibels, making the turbine suitable for installation in both residential and commercial areas where noise sensitivity is a concern.

Performance Across Wind Speeds

Low starting wind speeds of 1.5 metres per second with efficient operation from 2.5 to 15 metres per second. Maximum safe operating speed is50 metres per second, but is governed by the generator’s maximum revolutions per minute (rpm), ensuring reliably and safely performance within design specifications.

Efficiency

Efficiency ranges from 47 to 50 percent. This high level of performance demonstrates the suitability of EW Turbines’ micro wind turbine technology for effective energy generation in modern urban and transport settings.
