Wind Simplicity™ was founded in 2004 in Toronto, Canada by Sharolyn Vettese and her father, Dr. Alfred Mathieu.


Wind Simplicity’s Aim
Our team wanted to design a compact wind turbine to maximise the use of pollution-free, cost-free wind energy for the generation of electricity. We wanted wind power to be generated close to the point of use, which we think is the most effective mode of power generation.

There are significant environmental, security, political, cultural, economic and social advantages to a decentralized power supply. By having smaller wind turbines closer to electricity users, electricity loss due to transmission over long distances is reduced because generated renewable electricity is used first onsite. Greenpeace estimates 67% of primary energy input is wasted in the current global centralized power model and maintains that decentralizing is the best way to halve global CO2 emissions form power generation. With the Windancer, there is the added benefit of pollution-free electricity generation and the reduction of land use for generators because buildings like high rises can be used as towers or towers can be mounted near buildings.


We looked to the beauty and efficiency of nature (the maple leaf, the whale and the eagle) to solve the problems traditionally associated with wind turbines (including noise, vibration, size and aesthetics) to design a more compact, more efficient, safer horizontal wind turbine for all seasons adaptable to anyone, anywhere there are good wind resources and a good site, enabling them to become Consumer/Producers.™

Because the wind is variable, the Windancer had to respond immediately to the changing direction and speed of the wind via a direct drive, permanent magnet (radial flux) variable speed AC synchronous alternator.

The Windancer had to be an elegant, attractive wind turbine for all seasons that respects nature, is lightweight, noise- and vibration-free, safe for humans and nature including birds and bats, low maintenance, durable and suitable for a lower tower. The Windancer had to be suitable for connection to the electricity grid for net metering and/or stand-alone use/connection to a battery.
It had to be purely mechanical and long-lasting - a machine that could be easily repaired onsite by trained local people that was reconditionable without built-in obsolescence and made of recyclable material and heavy-duty top-quality parts.









The Windancer
Wind Simplicity's high-efficiency, compact, noise-free (3 kW, 7 kW, 23 kW) Windancer horizontal-axis wind turbine has a small footprint (refer to Specifications attachment). Designed to generate electricity close to users, it is compact yet highly efficient, minimizing loss of renewably-generated electricity due to transmission over long distances and land use. The WIndancer is ideal for urban, rural, remote-community and commercial/industrial use, it works effectively in variable low/high winds, turbulence, hail, ice, snow. It can be on- or off- grid, battery-connected, has unique safety features and its overall design is more visible to birds.

Innovative Design
The Windancer has 8 unique balanced “Samara” wind blades, inspired by the efficiency of the Canadian maple leaf’s winged seed, on 2 rotors, increasing blade surface area/wind efficiency. There are 4 Samara blades per rotor. The blades turn as one unit on the shaft that is turned by the direct-drive permanent magnet alternator. The Windancer’s unique, larger wind tail, inspired by the whale, ensures its wind blades always face the wind. It responds immediately to the wind’s changing direction. The Windancer’s design maximises electricity generation in low/high winds and minimizes turbulence. The new guiding principle is that the wind is the engine. The Windancer does not “harness” but "responds" to the wind as a dance partner eliminating conflict with nature and noise/vibration, making it safe and friendly to humans, animals and structures (the Windancer can be mounted on a variety of different types of engineered towers without guy wires – please refer to specifications attachment).

The Windancer’s features enable a smaller footprint and negligible noise and vibration so it can generate electricity closer to electricity users, facilitating municipal requirements.

The Windancer is self-starting in a 1m/s breeze (2 m/s for the Windancer23), without requiring electricity to start (compared to 3-m/s for average turbine). Low start-up enables it to perform in Canadian winter conditions (snow, ice, hail). Anodized aluminium blades ensure Windancer won’t rust near sea/salt for melting snow. Aluminium is lower maintenance than fiberglass, requiring less cleaning because it is non-pitting.

The Windancer’s innovative safety features include a permanent/stationary lightning arrestor at highest tip because putting lightning wires in the blades may interfere with TV/radio/computer signals and lightning may pass in-between blades and destroy the generator.
The tower can be lowered in advance of severe storms. Other safety features include:
• Automatic high-wind velocity control, adjustable
• Remotely controlled electric emergency brake
at low rpm
• Windblades lockout control on wind turbine
• Yaw (east-west) lockout control on wind turbine
• Windtail cabled to body
• CSA, or equivalent, approved
• Furling U on windtail for manually rotating wind
turbine out of wind
• Lanyard Contacts (3) for installers


The Windancer’s salient, balanced biomorphic design and human scale make a striking environmental statement connecting the community to the environment. The Windancer’s aesthetic can be democratized - it can be painted different colors/designs for environmental branding by corporations and to facilitate community participation, acceptance and ownership by organizations such as schools and churches. Color customization also facilitates visibility to birds.

Context
Because it’s high-efficiency, compact, lightweight with negligible noise/vibration the Windancer is easily adaptable to urban, rural, industrial, commercial, remote-community use. It’s low maintenance, easy to repair (direct drive, no gears, transmissions, computer parts), made of high-quality parts, has a low start-up speed and is self-starting (requires no electricity to start). The Windancer can be used on/off-grid and/or with a battery. The easily portable Windancer can be installed without cranes (3 kW/7 kW) and mounted on a variety of lower engineered towers without guy wires (free-standing or attached to buildings). A turbine for all seasons, it was designed to operate effectively in ice, hail, snow. Its anodized aluminium blades don’t rust. Other uses include heat exchange, water heating/pumping/purification and mechanical applications. It’s durable, reconditionable and recyclable (aluminium blades, steel body).



Manufacture and delivery
The Windancer is manufactured in Ontario, Canada using a top-of-the-range Alxion permanent magnet radial flux brushless alternator. Mostly off-the-shelf parts are used wherever possible to facilitate production and reduce consumer maintenance costs. The Windancer's modular design facilitates the production of larger models up to 80 kW. Made from anodized aluminum and steel, the Windancer can be recycled at the end if its life.

The Windancer is delivered to consumers in three parts and easily assembled onsite. The Windancer3 and Windancer7 are deliverable on a pick-up truck and do not require large flatbed trucks and large cranes, minimizing the impact of these vehicles on the environment. The Windancer can be installed without the need for cranes because it is compact.

The Windancer's ability to be assembled in three parts facilitates transport overseas as its mass/volume can be less than if transported as one unit. In line with green principles, the towers needed to mount the Windancer can be manufactured locally and local trades people can be employed to install and maintain the units.



Sustainability

The main function of the Windancer is to generate electricity from a renewable electricity source, the wind, which is potentially available 24/7, 365 days a year. The Windancer reduces pollution because it reduces the need for energy made from fossil fuels, such as coal, oil, natural gas, which not only pollute but can use up precious water resources. The Windancer does not need electricity to start and there are no emissions or noise pollution from the Windancer while it is operating.

With a small footprint the Windancer is highly efficient yet compact/lightweight for its kW output and designed to be close to the electricity user, minimizing electricity loss because it does not need to be transmitted over long distances and land use.

Purely mechanical (direct drive with no gears or transmissions) and made of top-of-the-range parts the Windancer is built to last, it can be easily repaired, reconditioned and recycled. The multiple blade-design of the Windancer is more visible to birds and bats. With a design inspired by nature’s beauty and efficiency, the Windancer makes a highly visible environmental statement raising awareness of renewable energy via its interaction with the wind, thus connecting the community to the environment.
