The assembly formed of the stacking of several symmetrical pairs of turbine engines is called a symmetrical tower pair, or twin towers. This eases the mounting/dismounting of the twin towers. This problem is even more acute when several turbines are connected to one another to increase the recovered powers. Indeed, from rivers to large ocean currents, the exploitable surface areas crossed by a cur- 2 rent typically vary from 100 m 2 to 100 km 2 , which corresponds, for a 2 m/s speed, to theoretically recoverable powers ranging from 400 kilowatts to 400 gigawatts. Summary of Invention There is provided herein a turbine engine comprising at least first, second, third, and fourth lift-type cross-flow water turbines, the first turbine comprising a first rotation shaft, the second turbine comprising a second rotation shaft, the first and second turbines being symmetrical to each other with respect to a plane, the third turbine comprising a third rotation shaft connected to the first rotation shaft by a first coupling device capable of compensating for spatial misalignments between the first and third rotation shafts, the third turbine forming, with the first turbine, a first stack of turbines, the fourth turbine comprising a fourth rotation shaft connected to the second rotation shaft by a second coupling device capable of compensating for spatial misalignments between the second and fourth rotation shafts, the third and fourth turbines being symmetrical to each other with respect to said plane, the fourth turbine forming, with the second 4 turbine, a second stack of turbines.
The turbine engine further comprises a control device capable of permanently maintaining the symmetry between the first and second turbine stacks with respect to said plane and of maintaining the rotation speeds of the first and second turbine stacks of equal values and of opposite rotation directions when the first and second turbine stacks are immersed in a moving liquid.

Ring-shaped portion 146B may comprise planar surfaces 147, in front of the foil tips of 25 turbine units, which join by curved portions 148. Curved portions 148 are capable of decreasing the drag due to ring shaped portion 146B along the flow direction. As compared with twin turbine engines 10, vertical members 22, 24 are intercon 5 nected by an element 32, playing both the role of a screening element by preventing the flowing of fluid between the two turbine units 12A, 12B, and of a strengthening element by improving the flexural rigidity of holding device 20 in plane P1 for a total drag force of direction Li.
3 is a perspective view of an embodiment of twin 15 towers 52 which corresponds to a stack of several twin turbine engines 10, the connection between two adjacent twin turbine engines being ensured by vertical members 22, 24. The turbine units are connected to one another to form two adjacent turbine columns 53A, 53B. More specifically, the rotation shafts of two 20 adjacent turbine units along the stacking direction are connected to one another. The rotating of twin towers 196 may be provided without power assistance via tail vanes 80 of the twin turbine engines which naturally tend to maintain line Ll parallel to the upstream current direction. Axes E and E’ are confounded to enable the assembly of twin towers 196 to rotate with respect to the ground. 20 In the case where the twin turbine engines forming the twin towers are provided with upstream anti-debris devices 106A, 106B, it may also be provided to rotate the twin towers to ease the cleaning of upstream anti-debris devices 106A, 106B.

Devices for recovering and converting the kinetic 5 energy of sea or river currents generally comprise a turbine comprising an assembly of blades adapted to rotate a shaft when they are immersed in the current. Sintomas de dolor de espalda alta . Indeed, if hydroelectric plants providing electric power from the 10 potential energy contained in impoundments (for example, dams on rivers) are widely spread, devices providing electric power directly from the kinetic energy of sea or river currents are generally still at the stage of draft. 15. Vertical members 90A, 90B are tangent to turbine units 12A, 12B without for all this being symmetrical with respect to plane P2. 2, twin turbine engines 70 comprise a vertical member 72 which is symmetrical with respect to plane P1 and which is arranged upstream of turbine units 12A, 12B with respect to the flow. Twin turbine engines 70 further comprise a vertical member 80 symmetrical with respect to plane P1 and arranged downstream of turbine units 12A, 12B with respect to the flow.
