27 years of experience in harnessing wind energy

"There is hardly any other technology which has made the same progress as wind energy in the past few years. Nordex is one of the fathers of this development. After all, we have been setting standards since 1985 with ever larger and thus increasingly more efficient turbines.

Many years of wind energy expertise, systematic engineering skills and customer-oriented product development are incorporated in each of the over 4,800 wind turbines which we have produced. Our range offers sophisticated and innovative wind energy systems for all geographic regions including coastal and non-coastal, strong-wind and weak-wind sites. Day for day, our hot and cold-climate models demonstrate their suitability for deployment in extreme desert and permafrost conditions.

Wind turbines

The third generation of our multi-megawatt series, the Gamma Generation, combines the latest research and development with technical know-how and experience from a decade of operation to meet today's market requirements. We offer different machine types for each wind class using a common technical platform: the N117/2400 for IEC 3 locations, the N100/2500 for IEC 2 sites and the N90/2500 for IEC 1 locations. Modular design allows us to add type-specific components and customer options.
The result: Nordex offers for varying customer and market requirements numerous different turbine types of the N90, N100 and N117 - all based upon this common technical platform." ... more

Maglev Wind Turbine Technologies, Inc.

"Wind power is a proven and highly effective way to generate electricity. However, today's wind mill type generators are inefficient, expensive, maintenance intense, hazardous to wildlife and require too much land. The design of the conventional wind mill has evolved into the 21st century. However, the basic science remains as old as their 16th century Dutch counterparts. If it were not for government subsidies and tax credits of all types, it would take a half a century to turn a real profit. The solution to the equation is the total transfer of the kinetic energy produced by the wind without friction. All horizontal axis wind mills use less than 1% of the available wind. A sailing vessel would never leave the dock if the sails and rigging were replaced with a large propeller attached to the mast. Initially, the wind must be captured not deflected to produce maximum power.

The Maglev Wind Turbine is designed to generate electricity from wind power with a new standard of efficiency.

MLWTH entered a new paradigm for wind energy. MLWTH energy strategy is to provide our customers with affordable, long term manageable costs for electricity, from environmentally sound, renewable energy supplies. One option is to upgrade the existing wind farms with the newest wind turbine technology. Upgrading existing 20-year sites will allow us to take advantage of both the existing infrastructure already in place and overall support for the existing location. New wind farms will also benefit from lower construction costs and less land acquisition requirements. " ... more

Magenn Air Rotor System (M.A.R.S.)

"Magenn Power's high altitude wind turbine called MARS is a Wind Power Anywhere™ solution with distinct advantages over existing Conventional Wind Turbines and Diesel Generating Systems including: global deployment, lower costs, better operational performance, and greater environmental advantages.

MARS is a lighter-than-air tethered wind turbine that rotates about a horizontal axis in response to wind, generating electrical energy. This electrical energy is transferred down the 1000-foot tether for immediate use, or to a set of batteries for later use, or to the power grid. Helium sustains MARS and allows it to ascend to a higher altitude than traditional wind turbines. MARS captures the energy available in the 600 to 1000-foot low level and nocturnal jet streams that exist almost everywhere. MARS rotation also generates the "Magnus effect" which provides additional lift, keeps the MARS stabilized, and positions it within a very controlled and restricted location to adhere to FAA (Federal Aviation Administration) & Transport Canada guidelines.

The Advantages of MARS over Conventional Wind Turbines: Wind Power Anywhere™ removes all placement limitations. Coast-line or off-shore locations are not necessary to capture higher speed winds. Reaching winds at 1,000-feet above ground level allow MARS to be installed closer to the grid. MARS is mobile and can be rapidly deployed, deflated, and redeployed without the need for towers or heavy cranes. MARS is bird and bat friendly with lower noise emissions and is capable of operating in a wider range of wind speeds - from 4 mph to greater than 60 mph." ... more

Kite Gen

"Kite Gen is the last evolution of wind energy exploitation. It is a radically new and innovative concept that may be the most practical and sound solution, in the market of renewable sources, to the world's energy needs and problems.

Kite Gen is pioneering a revolution on how to produce clean energy from wind, with the aim not only to compete within the current wind industry but, as still too rarely happens with renewable sources, to move the battlefield into the territory of fossil fuels.

Today's technology is just capable of scratching the surface, in few favourable points, of the enormous energy field contained into the wind (see Wind data). Wind turbines cannot reach higher and touch altitude wind, they are already close to their dimensional limits: difficultly hubs can be positioned at more than 100 m above the ground, the holding structure grows exponentially heavier, more unstable and above all more expensive with the height.

This situation may be compared with what happened in oil drilling, where only after having found better and better solutions it was possible to move away from the ground - downwards, in this case - and to reach the deepest and most profitable fields. To help visualizing the existing unexploited potential, just consider that the flight prohibited area over a nuclear power plant can easily get to contain 1 GW of wind power, equal to the power of the plant itself.

To reach altitude wind and exploiting its higher kinetic energy, the Kite Gen project starts from a radical change of perspective: no longer heavy and static plants like current wind turbines, but instead light, dynamic and intelligent ones. In the air, to subtract energy from the wind at an altitude of 800 / 1,000 m, power kites, semi-rigid automatically piloted high efficiency air foils. On the ground, all the heavy machinery for power generation. To connect the two systems, high resistance lines transmitting the traction of the kites and at the same time controlling their direction and angle to the wind." ... more

ENERCON Rotor blade concept

"When it comes to yield, noise emission and stress minimisation, ENERCON's rotor blade concept sets new standards in the wind energy sector. Because of their modified shape, the blades not only draw energy from the outer edges but also use the inner radius of the swept area, considerably increasing power output. The new rotor blades are also less susceptible to turbulence and provide an even flow along the entire length of the blade profile. In addition to the new design, the blade tips have also been improved to reduce noise emission and increase power output. Turbulence at the blade tips due to overpressure and underpressure is effectively eliminated in the rotor plane. The entire length of the blade is therefore utilised without any loss of energy caused by turbulence. The blades' high efficiency is reflected in power curves taken on all ENERCON wind turbines where power coefficients (Cp) of more than 0.5 are achieved." ... more
