Low Profile Wind Generator System

The trend in wind turbines is in the 2020s to make the towers remarkably higher. This is a consequence of the fact that very often the wind speeds are higher further away from the ground.

The negative side is that the towers and the blades are visible from long distances, changing the scenery. Calm and esthetically beautiful scenery is usually important for tourists, inhabitants of free time buildings, and for residential inhabitants. The latest plans of turbines describe turbines that are up to 260 meters high. This is the height in the new Danish plan to have 600 wind turbines around a
new artificial island on their Atlantic cost. China, UK and France are remarkable recent builders of wind power capacity.

The example of a 260 m high wind turbine will be visible from the seashore level to a distance of over 57 kilometres over an open sea. A common wind speed in there is often 3 m/s.

A commonly known low profile generator is called the vertical axis wind turbine, e.g. the so called Darrieus wind turbine. The original troublesome vibration is reduced compared to the original Darrieus design, if three helical blades are used. An example of such a turbine is a model from Turby. It generates 2500 W at 14 m/s. The height is 2.9 meters and the diameter 2.0 meters. The start-up wind speed ( 4 m/s ) is however relatively high e.g. for operations e.g. in Southern Finland away from the coast.

Benefits of the Rossi generator

The Rossi generator has a status of proprietary information. No patent application has been filed so far. There is some development work left to be performed by the new owner. More calculations, refining the concept design, mechanical and electromechanical design, and building the first prototypes are needed. I believe that the concept is new. However, I am giving no guarantees that the concept does not violate intellectual property rights of a third party. After the
release of proprietary information, the buyer candidate should do his or her own analysis of the concept.

Initially, a 6 m2 occupied area Rossi generator generates 370 W at 6 m/s. The calculations are conservative. If we compare to the above mentioned Turby generator, the Rossi generator of the same wind facing area would also generate over 2000 Watts at 14 m/s.

One feature of the Rossi generator enables it to however start at lower wind speeds than a vertical axis turbine.

The description of the structural solution creating this useful feature is available only under a signed non-disclosure agreement ( NDA ).

The Rossi generator could be placed to certain locations that are now not commonly used for generating windpower. This is an essential and the main benefit of the solution.
