Abstract

The device is a turbine that operates using solar thermal energy captured by radial absorption panels rotating about the axis of the turbine. The energy captured is transformed into mechanical work of a piston by expansion of a heat-transport fluid. This mechanical work increases or reduces the moment of the panels, thus creating a torque at the turbine which rotates generating electrical energy.

Description

Générateur d'énergie par capture solaire thermique et moment  Energy generator by solar thermal capture and moment
Description  Description
Il s'agit d'un dispositif de génération de l'énergie électrique à partir de l'énergie solaire thermique. En particulier, c'est un dispositif qui obtient le couple de la génératrice à partir de la différence des moments de plateaux radiaux.  It is a device for generating electrical energy from solar thermal energy. In particular, it is a device that gets the torque of the generator from the difference of the moments of radial plates.
La transformation de l'énergie solaire en énergie électrique est un procédé en plein développement et suffisamment mature pour une utilisation à large échelle dans le monde. Le principal obstacle aux technologies solaires réside dans le rendement et l'investissement qui impartent directement le coût de production aujourd'hui encore bien supérieur à celui des énergies fossiles. The transformation of solar energy into electrical energy is a process in full development and mature enough for wide-scale use in the world. The main obstacle to solar technologies lies in the return and investment that directly impart the cost of production today still much higher than that of fossil fuels.
En effet, les capteurs photovoltaïques viables économiquement ont un rendement faible de l'ordre de 15%. Ce rendement augmente aux alentours de 30% pour les panneaux à concentration CPV. Les capteurs thermiques à concentration CSP obtiennent aussi des rendements de l'ordre de 30% selon les conditions environnementales et d'installation. Ces derniers souffrent toutefois de beaucoup de pertes thermiques par dissipation lors du transport du fluide caloporteur, lors de la transformation en travail mécanique, ainsi que lors de la transformation en puissance électrique. Indeed, economically viable photovoltaic sensors have a low efficiency of the order of 15%. This efficiency increases to around 30% for CPV panels. Thermal sensors with CSP concentration also obtain efficiencies of the order of 30% depending on the environmental and installation conditions. These, however, suffer from a lot of heat loss by dissipation during the transport of the heat transfer fluid, during the transformation into mechanical work, as well as during the transformation into electrical power.
Notre invention permet de réduire les pertes dues à la dissipation thermique en supprimant la phase de transport du fluide caloporteur, et en réduisant les pertes dues à la Our invention makes it possible to reduce the losses due to the heat dissipation by eliminating the transport phase of the coolant, and by reducing the losses due to the

The generator we are going to describe draws its energy from the difference in temperature between the opposite plates.
Notre générateur a une forme et structure semblable à une éolienne. Il utilise le même système électrique des turbines des éoliennes pour produire un courant électrique alternatif depuis le travail mécanique de rotation. Grâce à sa simplicité dans la conception et les opérations, cette technologie nécessite peu de maintenance et présente plusieurs avantages tels que la réduction de bruit lors du fonctionnement, une durée de vie importante et un coût de fabrication faible et maîtrisé. Our generator has a shape and structure similar to a wind turbine. It uses the same electrical system of wind turbines to produce an alternating electric current from the mechanical work of rotation. Due to its simplicity in design and operations, this technology requires little maintenance and has several advantages such as noise reduction during operation, long service life and low and controlled manufacturing cost.
A la différence des éoliennes, le moyeu n'est pas relié à des pales conçues pour capturer l'énergie du vent mais plutôt à des tiges reliées à des capteurs thermiques par des liaisons glissières. La tige (12) est attachée au moyeu par un tronc (13) constituant ensemble un corps solidaire. Elle (12) est de forme cylindrique avec 3 parties coaxiales. La première partie proche du tronc (13) est de diamètre supérieur à la deuxième partie qui longe l'intérieur d'un cylindre creux (11). L'extrémité de la tige est constituée d'un piston (9) dont le diamètre est égal au diamètre intérieur du cylindre (11) assurant l'étanchéité d'un fluide caloporteur qu'il contient. L'ouverture du cylindre (11) est aussi de diamètre égal à celui de la deuxième partie de la tige (12) servant de fin de course au piston (9). Le bout extérieur du cylindre (11) est fermé avec un coude (8) bloquant le mouvement d'une deuxième tige qui a une liaison pivot avec le coude (8) à un seul degré de liberté de rotation au niveau du plan formé par le moyeu. La course de la deuxième tige est limitée par deux butée au niveau du coude (8). Un piston (6) constitue l'extrémité extérieur de la deuxième tige qui vient également s'insérer dans un deuxième cylindre creux (5). Le diamètre du piston (6) est égal au diamètre intérieur du cylindre assurant l'étanchéité d'un fluide caloporteur qu'il contient. Et de même, l'ouverture du cylindre est de diamètre égal à celui la tige servant de fin de course au piston (6). Le bout extérieur du cylindre creux est ouvert sur deux chambres (4) alignées formant un plateau (2) et disposant de surfaces noires (3) de capture des radiations solaires. Un poids supplémentaire (1) est attaché à la chambre extérieure. Les deux chambres (4) sont creuses et reliées par un troisième cylindre creux dans le même axe que le deuxième. Le troisième et le premier cylindre communiquent à travers des ouvertures (10) respectives reliées par un tuyau (7). Le fluide caloporteur circule librement et rempli les volumes des trois cylindres, du tuyau (7) et des deux chambres (4). Unlike wind turbines, the hub is not connected to blades designed to capture wind energy but rather to rods connected to thermal sensors by links slides. The rod (12) is attached to the hub by a trunk (13) together forming a fixed body. It (12) is cylindrical with 3 coaxial parts. The first part near the trunk (13) is greater in diameter than the second part which runs along the inside of a hollow cylinder (11). The end of the rod consists of a piston (9) whose diameter is equal to the inner diameter of the cylinder (11) ensuring the sealing of a coolant that it contains. The opening of the cylinder (11) is also of diameter equal to that of the second portion of the rod (12) serving as end of stroke piston (9). The outer end of the cylinder (11) is closed with a bend (8) blocking the movement of a second rod which has a pivot connection with the bend (8) at a single degree of freedom of rotation at the plane formed by the hub. The race of the second rod is limited by two stop at the elbow (8). A piston (6) constitutes the outer end of the second rod which is also inserted into a second hollow cylinder (5). The diameter of the piston (6) is equal to the internal diameter of the cylinder ensuring the sealing of a heat transfer fluid that it contains. And similarly, the opening of the cylinder is of diameter equal to that the rod serving as end of stroke piston (6). The outer end of the hollow cylinder is open on two aligned chambers (4) forming a plate (2) and having black surfaces (3) for capturing solar radiation. An additional weight (1) is attached to the outer chamber. The two chambers (4) are hollow and connected by a third hollow cylinder in the same axis as the second. The third and the first cylinder communicate through respective openings (10) connected by a pipe (7). The heat transfer fluid circulates freely and fills the volumes of the three cylinders, the pipe (7) and the two chambers (4).
Le générateur fonctionne lorsqu'il y*a une différence de température ou d'irradiation entre les pales opposées. Plus la différence est grande, plus le rendement est intéressant. Durant son fonctionnement, une moitié du dispositif est chauffée par radiations alors que l'autre est refroidie par convection et ombre. The generator operates when there is a difference in temperature or irradiation between the opposed blades. The bigger the difference, the better the return. During its operation, one half of the device is heated by radiation while the other is cooled by convection and shadow.
Ainsi, le fluide contenu à l'intérieur des cylindres et chambres est chauffé et dilaté en poussant le plateau et le poids à son extrémité. Ceci augmente le moment de la force gravitationnelle. De l'autre côté froid, le plateau est plié sur le coude ce qui cause une réduction initiale du moment de la force. En même temps, le refroidissement du fluide provoque sa compression forçant les pistons à rétracter le plateau contribuant ainsi à réduire son moment. L'effet de la combinaison entre la dilatation qui augmente le moment d'un côté et le pliage et la compression qui réduisent le moment de l'autre conduit à la création d'un couple faisant tourner la turbine et produisant l'énergie mécanique nécessaire à la génératrice afin de produire l'électricité. Thus, the fluid contained within the cylinders and chambers is heated and expanded by pushing the tray and the weight at its end. This increases the moment of the gravitational force. On the other cold side, the tray is bent on the elbow causing an initial reduction in the moment of force. At the same time, the cooling of the fluid causes its compression forcing the pistons to retract the plate thus helping to reduce its moment. The effect of the combination of expansion which increases the moment on one side and the bending and compression which reduces the moment of the other leads to the creation of a couple rotating the turbine and producing the necessary mechanical energy to the generator to produce electricity.
