Anyone who thought that three-bladed wind turbines were the only possible answer to harnessing the inexhaustible energy supplied by the wind, was wrong. While some alternative models promoted in Spain already indicate it, such as the Morcillo wind power system, the options are multiplying when the spectrum is extended to the rest of the world, where the search for more efficient solutions to harness wind energy continues. not, a lot of them surprising and absolutely disruptive.

- SheerWind: the turbine that searches the ground.
- Tyer Wind: the wind turbine that emulates the hummingbird.
- Morcillo wind power system: a generator with horizontal axis.

- Magnus – the Japanese hurricane resistant turbine.
- Kite Power Systems: kites that produce energy.
- Ogin: the turbine that powers the aerospace industry.
- Windstalk: wind power station and recreation area.
- Zephyr Energy: the micro wind turbine.

Extremely different ways of harnessing the energy of the wind. Projects which in the future could change the concept we have of a wind turbine. Let’s get to know a little more about each of these projects:
Vortex without blade. Wind turbines without blades.
The project Vortex without blade tries to upgrade the current 3-blade wind turbines to bladeless wind turbines. A second generation of wind turbines that can generate the same energy as traditional, but with clear savings in terms of production – operating costs and other environmental benefits – landscaping.
SheerWind: the turbine that searches the ground.
A very different approach from the previous ones is that led by Sheerwind who, with Instead of moving away from the ground, Invelox gets as close as possible. Thus, this idea starts from the location of the wind turbine in the lower part of a construction specially designed to capture the wind and take it underground. For this, a device is included which, in the upper part, is equipped with a kind of funnel that captures the wind and redirects it to the ground through a narrowed duct. In this way, an increase in wind speed is obtained. To all this are added the turbines, on land, which allow the production of electricity.
Is “New face of wind power”As defined by its developers, it can be installed close to end users and, according to Sheerwind, can improve the performance of a conventional 100 MW system by up to 280%.
Tyer Wind: the wind turbine that emulates the hummingbird.
“The revolutionary wind converter that mimics the movement of the hummingbird’s wings.” This is how Tyer Wind defines his striking wind turbine proposal which, they point out, replaces conventional blades with flapping wings that convert the kinetic energy of the wind into electricity. For this, the system is based on 3D kinematics, a “Revolution in the field of mechanics” With which this proposal manages to convert linear motion into rotary motion, as well as mimic the kinematics of birds such as the hummingbird. So much so that the fins of this vertical axis turbine emulate the movement of these birds to convert the energy of the wind. Although it still undergoes various tests, the promoters guarantee its high effectiveness.
Morcillo wind power system: a generator with horizontal axis.
Cheaper, safer and with less environmental impact. These are the guarantees with which the Morcillo wind power system is presented, a generator ‘Made in Murcia ‘capable of produce between 200 and 400 kilowatt hours and supply a hundred houses.
Altaeros BAT: turbines directly in the sky.
To harness the energy of the wind, height is key. Starting from this reality and widening the attention beyond the height of the masts, why not do without the ground and raise the energy recovery system to the sky? It may sound like an illusion, but to make it a reality Altaeros has been used, which offers as an alternative system to conventional wind turbines a aerostatic platform able to contain and raise a light wind turbine at 600 meters of the ground. According to its operators, the system is capable of producing twice as much energy as its conventional competitors.
Magnus – the Japanese hurricane resistant turbine.
From Japan comes this other system which, as you can see, is far from conventional wind turbines. Designed to be resistant even in the most unfavorable conditions, such as hurricanes, this alternative model designed by Challenergy and called Magnus, opts for the vertical axis and dispenses with the classic blades which, in this case, are replaced by a set of vertical. Columns. Its design is not random. With him, this system which combines the classic Magnus effect with the vertical axis it promotes better steering speed control, in addition to allowing it to continue to operate in strong winds.
In addition, its creators point out, the slower rotation of this system makes it more environmentally friendly, reducing the risk of bird collisions, as well as noise, compared to conventional models.
Kite Power Systems: kites that produce energy.
Still in the air, their generators are on display by UK-based specialist firm Kite Power Systems (KPS). And since that literally means comet, it’s clear that this element is the epicenter of this workaround. Specifically, there are two kites that would come into play in this proposal which By circular flight at high speed, it rotates the blades of a conventional turbine. The forces generated with this type of flight would pass to a generator to which both wings are subjected. To make everything happen, while one of the kites flies in a circle, the other is returned to its original position, so that the energy generation remains constant. With this, assure the promoters, the captured energy is optimized thanks to the flight in height with much more powerful winds.
Ogin: the turbine that powers the aerospace industry.
Back on the ground, this Ogin Energy solution explores on the horizontal axis of conventional wind turbines, to maintain the mast but completely rethink its upper part in which, instead of blades to be used, these turbines are chosen which fit perfectly housed in a circular cover. The design of today’s wind turbines “It is based on the classic principles of 18th century windmills”, they assure the company that it has given a twist to this method to “take advantage of the latest advances in the aerospace industry to modify the airflow patterns “.
With a modular design that facilitates the transport and installation of this system, the Ogin turbine allows an increase in the amount of air, in addition to being able to continue to operate in strong winds. With all this, the capacity compared to conventional systems is increased by 50%.
Windstalk: wind power station and recreation area.
More than 1,200 poles 55 meters high and with an oscillation between 10 and 20 meters. This is the alternative proposal of Atelier DNA, which undertakes to Windstalk. Whatever its results, the visual effect it causes has an impact. This is so because on nights when the sticks are flapping in the wind, 50 centimeters from the top end illuminated by LEDs, offering the result visible in the image or, in situ, walking under this particular wind turbine installation, in which there would be no danger neither to walk nor to lean on the poles.
At the base of each unit there is a chamber which houses the generator. There, the kinetic energy of each of these poles, which make up the piezoelectric ceramic discs, between which the electrodes are located, is converted into electrical energy. When the wind swings the pole, the discs are compressed, thus generating a current through the electrodes. The proposal aims to be two in one: a facility for the capture of clean energy and a space for public recreation.
Zephyr Energy: the micro wind turbine.
The latter approach is radically different, in this case that of Zephyr Energy Corporation which, with Windbeam, bet on a micro-wind turbine which also changes its application. In this case, it is designed for small-scale use, for example to recharge batteries or to supply the energy necessary for small electronic equipment.
Capable of operating in winds as low as 2 miles per hour (just over 3 kilometers per hour), the system consists of a horizontal beam which, when exposed to the wind, begins to move freely from above. at the bottom, which generates small amounts of energy. , however sufficient for the uses described.
The tree of the wind. An innovative source of wind energy for cities.
Three years of research and development were necessary for a team of French engineers to design their interpretation of wind power for cities. The Wind Tree is an innovative tree-shaped wind turbine.
LIAM F1: small urban wind turbine that can make homes energy self-sufficient.
Designed by “The Archimedes”, a Dutch renewable energy research and development company, LIAM F1 UWT is a new generation of wind turbines for domestic use that produces much more energy than current ones and generates little noise, is currently under development and continuous improvement.
O-Wind Turbine: the spherical microturbine that captures the wind in all directions.
Inspired by a NASA space rover, winner of the British James Dyson Prize in 2018, it is a spherical microturbine capable of picking up wind from all directions.
