Buoyancy motor

Abstract

The "buoyancy motor" according to the invention uses for its drive the buoyancy force exerted on an air-filled buoyancy body with internal volume V in the water. The upward movement, which concludes with a reduction of the internal volume to 0 and thus deactivation of the buoyancy body, occurs by a height H and is transmitted via a linear-to-circular converter to a crankshaft with a flywheel, which completes half a revolution. Subsequently, the deactivated buoyancy body is lowered by H by the action of the flywheel, including the return of the internal volume from 0 to V, with another half revolution of the crankshaft and flywheel. The described movement processes then repeat, the stages of which are illustrated in Figures 1 to 4.

Description

A Basic components of the lift engine

[0001] Fig. 1 on page 8 / 9 is the schematic diagram of the basic components of an exemplary basic configuration of the lift engine with 1. Container 2. cylindrical bollard 1 3. Water filling of the upper part of 1 4. Stop element connected to (5) for one of the bollard 2 elements (7) 5. “Cover” for buoyancy body from (5) plus (6) is located in a watertight or almost watertight sliding seat in (6) 6. cylindrical “cup” for air-filled buoyancy body made of (5) plus (6) 7. cylindrical bollard 2 8. Drive element “pipe” with the additional function of outside air compensation and leakage water drainage from (5) plus (6); guided in a watertight sliding fit through (1) and rigidly connected to (6) 9. Crankshaft with flywheel 10. Guide element rigidly connected to (8) for the crank of (9)

[0002] Note: In the relative position shown, (5) and (6) are locked against each other by a simple mechanism, not shown, which is released when (5) is inserted into (6). B Characteristic configurations during one crankshaft revolution

[0003] Fig. Figure 2 shows the configuration after three-quarters of the stroke H of the lift body (5) plus (6). The crankshaft has rotated correspondingly counterclockwise.

[0004] Fig. 3 shows the configuration after a complete stroke H. The cover (5) has been lowered into the cup (6) by bollard 1 (2), so that the buoyancy body no longer contains any air and is thus deactivated. The crankshaft has moved relative to Fig. 1 rotated by a total of 180°.

[0005] Fig. 4 shows the configuration after lowering the deactivated buoyancy body compared to Fig. 3 by three-quarters of H.

[0006] Fig. Figure 1 shows the configuration after lowering the buoyancy body by a further quarter of H, whereby the cover (5) has been pulled out of (6) again due to contact between the stop elements (4) and the bollard 2 elements. The crankshaft has rotated a total of 360°. C Energetic analysis of the movement process

[0007] The buoyancy energy of the buoyancy body is, neglecting the loss due to the air cross-section of pipe (8), EAUF / (kp⋅m)≅−[h / 2) / m]⋅V / ltr.

[0008] In this equation, h is the stroke of (6) in configuration Fig. 2 after Fig. 3, or the lowering of (6) in Fig. 3 after Fig. 1 and V the air content of the buoyancy body from (5) plus (6) according to Fig. 1 and Fig. 2. EAB / (kp⋅m)≅[(h / 2) / m]⋅V / ltr

[0009] This energy is required for the lowering of the buoyancy body by H including its restitution according to Fig. 1 is required and is applied by the moment of inertia of the flywheel plus the crankshaft (9), so that the total useful energy turnover E / / (kp⋅m)≅EAUF / (kp⋅m)−EAB / (kp⋅m)=[(H−h) / m]⋅V / ltr remains. The weight of the buoyancy body with the connected elements is identical for the lift and downforce phases and therefore does not affect E. The drive power of the buoyancy motor is E / T with a speed of 1 / T. T is likely large due to the considerable flow losses of the buoyancy body in the water and is in the range of seconds. C Variants of the lift engine

[0010] In particular, the following variants compared to Fig. 1 are available : • Higher water density through the addition of salt for greater buoyancy • Other fluid medium with higher density than water for greater buoyancy forces • h / H<¼ instead of h / H=¼ for greater useful energy • More elongated shape of the buoyancy body in the vertical direction for lower flow losses in favor of a lower T and consequently higher propulsion power. D State of the art

[0011] No comparable engine concept is known. E Applications of the lift motor

[0012] The buoyancy engine is characterized by its energy self-sufficiency and zero emissions. Possible applications include the generation of electrical energy and the production of hydrogen through water electrolysis.

Claims

[1] A buoyancy body located in a water tank with an internal air volume V at the beginning of a buoyancy process around the stroke H, which is transferred to a crankshaft and flywheel by a system for converting linear to circular movement, whereby these rotate by 180°. At the end of this buoyancy process, the internal air volume of the buoyancy body has been converted to «V and, if possible, 0. Thereafter, a downward movement of the buoyancy body by H occurs due to the action of the flywheel with restitution of the internal air volume V at the end, whereby the crankshaft and flywheel have rotated by a further 180°. After that, the described movement processes are repeated. [2] Filling the water tank with a liquid medium with a higher density than water in order to achieve higher buoyancy forces of the buoyancy body and higher drive power of the buoyancy motor.
