They produce more efficient domestic wind generators without visual impact

One of these RidgeBlade wind turbine without any blades and placed on top of the roof, using a design that makes it almost invisible. The mechanism collects and condenses the wind from the outside after being placed in a place where the wind is ‘pushed’ to go (preferably at the top of a pitched roof).

When the wind is forced to go uphill on the surface of the roof where the turbine is located, it can reach a speed of up to three times higher. to the person he has under normal circumstances. That way, the turbine can generate up to nine times more energy than a conventional wind turbine, according to the company’s website, https://thepowercollective.ca/

The RidgeBlade uses an advanced system to prevent noise from occurring during normal operation, and is also designed to self-limit the rotor speed thanks to its mechanical properties.

These wind generators reach their full capacity at wind speeds as low as 40 km/h.a speed that is not exceeded even in severe storms, thus ensuring great stability when the turbine reaches its maximum rotation speed.

The RidgeBlade has been tested in real-world conditions, both inside a wind tunnel and outdoors, in winds of more than 100 mph with no loss of efficiency.

The company, headquartered in Canada and having representations in various cities in the United States and Europe (currently France and Italy), currently selling two models. One of them is the Residential RB1, which is the smallest home version and is suitable for most homes.

The RB2 Commercial, on the other hand, is a larger and more powerful version and is designed to be installed in a wide variety of buildings. It provides higher power than the RB1 turbine.

There is also a hybrid version that includes a photovoltaic panel to combine solar and wind generation.

Nemoi, another local alternative

However, it is not the only company committing to new models of more modern and efficient wind turbines. Owned by two Argentine businessmen, Semtive has created the Nemoi, a turbine that is vaguely reminiscent of traditional turbines but much more discreet (about the size of a bush) and much more discreet. three vertical blades that rotate completely silently like a carousel around a central axis.

According to the company, one of these turbines can power a four-person household at speeds of only 16 to 20 km/h. The mechanism, which can be assembled by one person, is made of aluminum and can be produced anywhere.

Why is a small turbine like this so efficient? The company’s president, Ignacio Juárez, explains that one of the reasons is that it is at these domestic facilities. No energy is lost during transport as it is produced where the mill (usually several kilometers away) and the house are located.. This means that up to 40% of the energy produced is lost along the way.

In this case, since the generator is in the house itself, all the energy produced is used. These turbines, which have different models according to their capacities, retail price of about $3,600, however, the company calculates that owners of these systems can recover their investment in just two years if they take advantage of the subsidies that administrations usually give or in very windy areas, and a maximum of seven years in low wind areas. No wind and subsidies.

From Semtive, customers often use these turbines as a complement or even alternative to solar panels.
