Bienvenue dans la page consacré au projet '''Turbinolienne'''.
Ce concept inédit à pour vocation de produire de l'énergie avec l'aide du vent ou de l'eau. 
A l'initiative du projet : Slim Mazari.

Projet de construction d'une éolienne horizontale. D'après nos calculs, sa puissance pourrait être de 40 fois supérieure aux éoliennes traditionnelles.

Ce projet est en attente d'aide de la part de contributeurs qui pourraient nous aider à réaliser un prototype.

== Historique du projet ==

Sur le chantier d’extension du lycée technique de Provins, sur une grue Liebherr, et à cause d’une coupure inopinée du courant, le comportement de la grue m’a démontré la puissance du vent sur la flèche de 45 mètres, avec une benne à béton de 2 tonnes située à 35 mètres et un vent d’environ 35 km/h : ma flèche a été emportée et traînée avec la benne sur plusieurs mètres avant que je puisse rétablir la situation.

Ce phénomène m’a fait penser à utiliser une grue pour prendre le vent et non lui résister.
C’est ainsi que le projet des Turbinoliennes a pris forme.

== Fonctionnement ==

Ma volonté fut d’améliorer les capacités de production tout en croisant les contraintes en symbiose (Hommes, Nature, Machines.)
Vingt-quatre mois de recherche dans tous les domaines de l’énergie renouvelable me permettent de constater que les éoliennes du futur ne peuvent être qu’horizontales et leur mécanisme, simple et éprouvé.

La possibilité de recycler les flèches et contre flèches des grues réformées peut être envisagée, ce qui réduirait considérablement le coup de fabrication. Ou au contraire, fabriquer des flèches profilées pour les TURBINOLIENNES.

A chaque bout de flèche, une aile équilibrée grâce à un contrepoids, et réglée par trois vérins, garantit une ouverture et une fermeture douces, qui suit la pression du vent.

Tous les points de frictions sur la couronne sont équipés de « fero-nano-fluide » et d’aimants néodymes ou blitzmut pour les dynamos. Nous transmettrons une induction rotative sur la couronne qui repose sur un bain de « fero-nano-fluide ».

Quant aux dynamos, il peut y en avoir une sur chaque niveau, ou une grande suspendue en sous-sol, avec la cage d’aimants tournant dans le sens contraire de la bobine. Cette disposition devrait accroître considérablement la puissance du champ électromagnétique.
Les brames doivent être lourdes et inaltérables. Elles seront synchro-mobiles sur les trois flèches d’élan. Par grand vent, elles se rétractent et, par vent faible, elles s’écartent du point central jusqu’aux butées, sans dépasser la ligne de force.
Les flèches d’élans peuvent être plus nombreuses 5, 7, 9, 21.
La vitesse de rotation de l’ensemble de la structure permet l’équilibrage sur son axe central.

Les '''cônes d’élans souples et rétractables''', sont garants d’une continuité dans la production des forces nécessaires au bon fonctionnement des turbinoliennes.

Sur l’axe central le ou les groupes d’électricité sont couplés à des cadrans trochoïdaux débrayables, afin de permettre une maintenance simple et sans risque.

La hauteur de l’ensemble, perroquet compris, peut varier. L’étude d’effet de site permet de la définir aux mieux du confort visuel et sonore des habitants de proximité.

L’utilisation de techniques novatrices, induction des fero-nano-fluides, mécanique des fluides, batteries, thermologie, aérodynamique, hydrodynamique, chimie biomoléculaire, auto-maintenance, aidés par l’électronique et l’informatique, font partie de cette invention.

Elles suppriment quasiment tous les bruits liés aux anciennes éoliennes, trop hautes, trop bruyantes et trop coûteuses à l’implantation comme à l’entretien.

Une Turbinolienne équivaut à plusieurs éoliennes traditionnelles de 1,5 Mgw.

Les Turbinoliennes sont conçues pour apporter l’énergie à tous, à moindre frais et sans émission de CO2.

Elles s’inscrivent dans l’évolution technologique du développement durable.

La stratégie que nous souhaitons adopter est un fonctionnement sans arrêt du système. Pour cela, il faut choisir des matériaux durables demandant un minimum de maintenance.

Pour fabriquer les TURBINOLIENNES, la recherche dans de nombreux domaines est impérative.

1) Recherche en bio chimie moléculaire pour les éléments qui la constituent.

2) Recherche en mécanique, « engrenages tronchoïdaux, réducteur accélérateur».

3) Recherche en mécanique des fluides.

4) Recherche en électronique, champs électromagnétiques, induction.

5) Recherche en informatique, pour les programmes de pilotage et les systèmes de sécurité.

6) Recherche en nanotechnologie : fero-nano-fluides pour supprimer les frottements pour la couronne, « néodyme, blitzmut, nano quarks, pour de nouvelles dynamos et des batteries plus propres et plus puissantes.

7) Recherche en aéronautique et hydrodynamique : profilage des ailes, haubans et cône.

8) Recherche en optique, les lasers et les lentilles de Kepler peuvent être améliorées.

9) Recherche en thermologie.

10) Recherche en robotique filoguidée

11) Recherche en auto-maintenance et autoréparation.

Nous avons ici quelques exemples des recherches que nous pouvons entreprendre, en ce qui concerne les « terriennes ».

=Overview=

Open Source Ecology is involved in researching, developing and building open-source technologies for clean, local electricity-generation. As well as [[:Category:Solar Power|solar power]], we like wind power. Wind power or solar or both may be appropriate, depending on local materials and local weather conditions.

Specifically, we are interested in open-source designs for a wind turbine that can provide electricity for a small community. Small wind turbines like this are usually 7 feet (2m) to 25 feet (7.6m) in diameter.

[[Open Source Ecology Europe]] and -[[Germany]] are working on a prototype VAWT design: [[Germany/Wind_Turbine]]. Research and development is currently concentrated at [[TiVA]], a tiny wind turbine prototyping platform. With this very small turbine, we can easily change parts, try out new ideas and increase the quality of the design on a small scale in a fast and inexpensive way.

==Design specifications==
*'''Scalability''' - scalable from ??? to ???
*'''Low-cost''' - must cost less than $1 per installed watt and $0.05/kWh produced on a medium speed site (6m/s average speed [13.4mph, 21.6km/h])
*'''CAD files''' to allow parts to be digitally fabricated. We could just take an existing open-source design, and get one of our draftsmen to make the CAD file. Good CAD files could allow for scalable digital fabrication: the blades could be printed in a range of sizes, depending on what you need

==Existing open-source wind turbines==
Several wind turbines have already been open-sourced and it should be possible to use them for the [[Global Village Construction Set]]:

*[http://www.applied-sciences.net/library/zoetrope.php '''Zoetrope'''] is a vertical-axis wind turbine made from common materials such as stove pipe, metal brackets, plastic sheet and a trailer hub. Generates about 150-200W in winds of 20mph (32km/h). [http://www.applied-sciences.net/library/data/zoetrope-wind-turbine.pdf Construction Guide]. The major parts are: [http://69.175.14.181/catalog/product_info.php?cPath=22_30&products_id=175&osCsid=11bdc6671edf38fcc578ca1da051f8d8 parts kit for $159] (unless you could order one from a Fab Lab/ a hackerspace with a water-jet cutter), [http://www.amazon.com/2x1x1-Turbine-Generator-Neodymium-Magnets/dp/B0012DIXE4 24 neodymium magnets for $140], [http://www.etrailer.com/Trailer-Hubs-and-Drums/Dexter/34822BX.html?feed=npn trailer hub for $26]. There are also a bunch of pieces like nuts and bolts, but those are the main one, and come to $425 excluding shipping.
*[http://www.otherpower.com/otherpower_wind.shtml OtherPower.com] have several complete plans for wind turbines that can be built at home. Their site has -
**[http://www.otherpower.com/turbineplans.shtml Complete plans for a 10 foot (3m) turbine] that puts out 100W in 10mph (16km/h) winds and 700W in 25mph (40km/h) winds.
**[http://www.otherpower.com/bigmills1.html Design of a 14 foot (4.25m) turbine] that does 200W in 10mph (16km/h) winds and 1500W in 25mph (40km/h) winds. This is the record of a project rather than a replicable open-source design.
*[http://www.velacreations.com/chispito.html '''Chispito''' Wind Generator]. Chispito is made from recycled/salvaged materials, completely open-source with clear instructions and designed for simplicity. Open-source instructions for building both the turbine and the tower are available. Each turbine generates about 100W; most people seem to use a bunch of them. This is probably smaller that what we are looking for.
*http://www.scoraigwind.com/ has a lot of information on wind turbines, but no fully open-source plan

==What kind of turbine?==
The first design decision we have to make is which kind of wind generator best suits our needs

===Vertical Axis Wind Turbine===
[[File:Pac_wind.jpg|200px|thumb|right|Pacwind VAWT Vertical Axis Wind Turbine Seahawk]]
Verical Axis Wind Turbines or VAWTs offer a number of advantages over traditional horizontal-axis wind turbines (HAWTs). With careful layout they can be [http://media.caltech.edu/press_releases/13430 packed closer together] in wind farms, allowing more in a given space. This is not because they are smaller, but rather due to the slowing effect on the air that HAWTs have, forcing designers to separate them by ten times their width. VAWTs are rugged, quiet, omni-directional, and they do not create as much stress on the support structure. They do not require as much wind to generate power, thus allowing them to be closer to the ground. By being closer to the ground they are easily maintained and can be installed on chimneys and similar tall structures.

In addition, by being closer to the ground, VAWTs have the ability to take advantage of the tunnelling effects of small buildings and structures (provided the structures are build close enough) small VAWTs are also used in corners of buildings (usually the corner of a balcony).

Although VAWTs are not as efficient as HAWTs they are considered more reliable and much easier to maintain. Some disadvantages of VAWT are:

* Some designs are non-self starting
* Blade that moves ''into the wind'' also moves ''against'' the wind, slowing down the turbine and causing buffeting that decreases blade service-life in a manner similar to helicopter blades. This could be addressed by a shield that adjusts to the direction of the wind and covers the blade that moves into the wind. This could be done with some kind of vane. However, this would complicate the design significantly, incl. bearings for the shield. So this may not be worth it ... probably easier to just build more VAWTs or build them bigger. But who knows ? Come up with a good sail/shield design and this might be just the breakthrough that VAWTs have been waiting for.
* [http://en.wikipedia.org/wiki/Gorlov_helical_turbine Gorlov helical turbine] design which solves the pulsatory torque experienced by the blades during each revolution is patented.

A good step by step guide can be found on [http://www.instructables.com/id/VAWT-Lenz-type-Stage-1-Converting-wind-power-to-/ this link]: a small Savonius wind turbine that takes advantage of the [http://en.wikipedia.org/wiki/Venturi_effect Venturi effect].

There is a small scale printable VAWT on thingiverse http://www.thingiverse.com/thing:6899

===Horizontal-axis wind turbines===
Scoraig Wind has proven the viability of low-cost HAWTs using short wooden blades on a high-rotational-velocity freely-spinning rotor, with hand-wound alternators, in contrast with typical high-power commercial HAWTs that slow blades down using a gearbox (usually the first part to break down, sometimes with a ~5-year service life, and even catch fire during storms), however their plans are not yet open-source.

[[Shrouded wind turbine|Wind Lens]] style turbines have been shown to increase the power output of a HAWT by 2-5 times for a given size, and some designs for appropriate shrouds are freely available.

===Airborne wind turbines===
A turbine attached to a lighter-than-air ballooon, such as being developed by [http://www.magenn.com/ Magenn]. I think we can reject this as too complex and too experimental for our purposes.

#[http://www.google.com/patents/about?id=2is6AAAAEBAJ Wind driven apparatus for power generation] - expired patent for a tethered airborne turbine. This design generates power at the turbine and transmits it to the ground.
#[http://peswiki.com/index.php/Directory:High_Altitude_Wind_Power High Altitude Wind Power at PESwiki]

===Kite generators===
A high-flying power kite tethered to a generator on the ground. The kite tugs on the tether, which spins a turbine and generates electricity. All the machinery can be kept at ground level; only the sail is airborne. This allows for easy maintenance.

The two main advantages of this design are that reaches the more powerful winds higher up, and it may come in cheaper than a turbine. [http://cfpub.epa.gov/ncer_abstracts/index.cfm/fuseaction/display.abstractDetail/abstract/8602/report/F This] report from the WPI Kite Power Team says there is an "anticipated 50% cost savings over wind turbines".

We can probably buy an off-the-shelf power kite. [http://www.aliexpress.com/product-fm/397570670-Kite-Power-Kite-Sport-Kite-5sqm-Sail-Area-Power-Tricktion-Kite-Quad-line-Control-wholesalers.html Here] is a 5m2 one for $166. [http://www.virtualvillage.com/Items/003300-010 Here] is a 2.7m2 one for $14. [http://www.powerkiteshop.com/ozone_method.htm This] seems to be a top-of-the-range one - it's $600 for 6.5m2. Alternatively, we could try to build our own kite.

This would need to be attached to the open-source [[electric motor]] we're designing, and a microcontroller. All the hardware is on the ground, which makes maintenance and set-up easier. The control will be the main design challenge.

Kites can extract power more economically than wind turbines because they fly at higher heights than turbines can operate."''
#http://www.kitegen.com/en/?page_id=7

==Siting of Turbines ==
A critical step to make wind profitable or optimal is putting the turbine in the right spot or site (turbine siting). This involves two main factors: the speed of the wind and the turbulence in the wind. Since the energy available in the wind varies with (E ~ v^3) a site with slightly less speed can produce a lot less energy. Siting requires measuring the speed of the wind for at least a year with a measurement mast (or small weather station) in a spot close to the site of the turbine. There exist open-source software to then propagate the measurements (using more or less complex computational fluid dynamics) to find the speeds on the topography. One example: http://awsopenwind.org/

=Review=

From MJ, 8/28/12 -

VAWT windmills are one of those things that many inexperienced people find the holy grail in, and they could work, but are there any economically competitive variants?

From my understanding, this is one of those things that for a robust, large scale model - the costs go way up. It is one of those things where people say 'Eureka' for small, working models (they do work) - but scaling them is difficult.

So the question is, if HAWTs are proven, why pursue VAWTs, which are not economically proven? Simple fact: how many VAWT wind farms have you seen, and how many HAWT wind farms have you seen?

The analysis that one should do is this:

#Is there data from a small prototype?
#Is the small prototype scalable to a full machine while not decreasing performance/cost ratio?
#Are there performance calculations?
#Is there economic analysis?

So my conclusion is that unless there is evidence that the performance to cost ratio can exceed that of HAWT designs, we should go with the HAWT. This has to consider the lifetime of the turbine.

===Wind Power with Hydraulic Transmission===
Back in the [http://en.wikipedia.org/wiki/Dutch_golden_age golden age of the Dutch], their booming economy was powered by wind in all sorts of incarnations (see article from Low-tech Magazine - [http://www.lowtechmagazine.com/2009/10/history-of-industrial-windmills.html Wind powered factories: history (and future) of industrial windmills]). Wind provided a lot of energy but one big problem was that this energy had to be used at the time that it occurred, with very little ability to store it for later use. Now in the 21st century, we can use hydraulic implementations to solve this problem. As builders of the [[GVCS]], we are quite familiar with hydraulic systems from projects such as [[LifeTrac]]. A hydraulic transmission can also be used for stationary applications and powerd by wind. The "mill" that harvests the wind is coupled to water pumps, generating hydrostatic pressure. With a storage reservoir (water tank at higher level), this energy is available at any time, powering hydraulic motors.
