A Zero-Blade Non-Rotational Wind Converter
A new bladeless wind technology has been developped to harness the wind differently and more efficiently. The Saphonian has no blades, does not rotate, and its design is largely inspired from sailboats. It is a serious attempt to provide a clean, cheap and storable source of energy.

A Solution for Radar Interference
In the past year, the pages of Windtech International have been filled with excellent strategies to counter NIMBYism and the vested interests that sometimes lie behind such views. However, NIMBYism is by no means the only obstacle to wind farm development across the globe. Despite the tough targets for renewable energy production set by governments, huge numbers of wind farm proposals lie gathering dust in planning offices due to the concerns of airport air navigation service providers (ANSPs) and defence ministries.

A New Offshore Wind Atlas
In 2008 an EC FP7 funded project, NORSEWInD, was launched with the aim of addressing the lack of data available for offshore wind development. The project's aim was to provide a new offshore wind atlas for the Irish, North and Baltic Seas. This article follows on from an earlier article, published in the October issue 2008 of Windtech International, introducing the NORSEWInD project.

Lowering the Cost of Wind Power to Better Compete
As renewable sources such as wind and solar compete as serious contenders in generating more energy for the world, the energy produced must be as cheap, if not cheaper, than that of fossil-based sources. In addition, the quality of energy produced must be equally as high. The formula for lowering the cost of energy from any source is ultimately very simple: lower overall capital investment costs, equipment lifetime operation and maintenance (O&M) costs and fuel costs, while boosting the amount of energy generated. This formula becomes even more attractive with wind and solar – as the cost of fuel is already free. In the end, it all comes down to five main drivers that have a major effect on lowering the cost of energy with renewable sources.

Making Inspection More Cost-Effective
In this article, Marcel Bruins explains how rotor blades can be inspected using drones. The idea of performing rotor blade inspections in a safer and more cost-effective way was conceived a few years ago, when he was still working for a rotor blade repair and maintenance company (previously Aerpac in Almelo, The Netherlands, which was later taken over by GE Wind Energy). Marcel currently works as a project manager for the International Business Support department, at Availon GmbH, the largest independent service provider in Europe.

The New Control Platform
kk-electronic has been an active participant in the wind power industry since its early days and we have been able to influence the development of the industry with our products and innovations. Our first control system (in 1978) gave the ability to connect to the grid, and since then five generations of products have refined and optimised the performance of control systems and wind turbines. The newest solution from kk-electronic – the ‘C’ control platform – was introduced in April 2012. This new control platform breaks with traditional thinking about control systems, since it adds several new dimensions to the product category.

Potential and Limitations
During the last two decades of commercial wind turbine development one of the most obvious trends has been the growth in the size of turbines and the rotor blades to drive them. Along with this the average rotor power loading has decreased to values about half those of ten years ago. Some of the recent turbines are new models especially designed for low wind speed regimes, but most of them are existing wind turbines equipped with larger and larger rotor blades. The following article gives some insight into the possibilities and limitations of such turbine derivatives and will pay particular attention to the need to alter other turbine components as a result of the increase in the rotor diameter.

| Every week on our website and in our email newsletter we want to show you that wind energy is more than just technology. We therefore invite you to send stunning pictures of wind turbines inspired by “light” (in the broadest sense of the word). After 52 submissions we will announce the winner of the year’s best picture! Email your photo to Include turbine model, location and name of photographer. (size of the published photo will be 336 px width x 280 px high). |
