Buoyant force utilization device

A buoyant force utilization device (1.0) for utilizing and converting kinetic buoyancy energy and/or potential energy into mechanical and/or electrical energy, comprising the following components:

• a) a first space (1.1) filled with a first medium (2.1),
• b) a second space (1.2) filled with a second medium (2.2),
• c) at least one buoyancy body (3.0),
• d) a circumferential guide (4.0), wherein movement of at least one buoyancy body (3.0) takes place along the circumferential guide (4.0),
• wherein the circumferential guide (4.0) runs through the first space (1.1) and the second space (1.2),
• characterized in that the circumferential guide (4.0) comprises an endless rail system,
• wherein the first space (1.1) and the second space (1.2) are separated from each other at at least one point by a lock system (1.3),
• wherein the lock system (1.3) has a permanent opening,
• wherein the buoyancy body is designed such that its average density and its buoyancy are dependent on a temperature,
• wherein the temperature of the first medium (2.1) and the second medium (2.2) differs,
• wherein the device is configured such that an external energy source induces a difference in temperature between the first (1.1) and second space (1.2),
• wherein the surface of the buoyancy body (3.0) facing the first medium (2.1) and/or second medium (2.2) comprises a profiling (5.0).
