摘要： A device for converting thermal, mechanical and/or electrical energy quantities into other such energy quantities comprises at least one volume (97, 98, 127, 128, 129) comprising a liquid quantity (31, 32, 130, 131, 132, 202) and at least one partial volume (33, 34, 133, 134, 135) with a working medium. The partial volume is bounded by volume delimiting elements and a liquid surface. At least one of the volume delimiting elements or the liquid quantity can change its position relative to other volume delimiting elements or the liquid quantity in such a way as to change the size of the partial volume. The partial volume and the liquid quantity perform a rotational movement so that centrifugal forces act on the liquid quantity. Heat quantities are suppliable to or removable from at least one liquid quantity in that a part of the liquid quantity can flow into and out of the volume from outside the device through openings (49, 50, 52, 149) or in that the at least one liquid quantity is thermally coupled to another liquid quantity by heat exchangers.
A thermoelectric, thermomechanical or thermal converter with at least one of the devices is provided, with which a Stirling, Ericsson, Vuilleumier, Clausius-Rankine, Joule process or a mixed form of the processes is realized.

摘要： In an example, an engine includes a thermal expansion unit comprising expansion material that expands in response to a temperature increase of the expansion material and contracts in response to a temperature decrease of the expansion material. The engine includes a structure comprising a heat receiving region, wherein at least a portion of the thermal expansion unit is disposed within the structure. The heat receiving region is configured to transfer thermal energy from a source of thermal energy to the expansion material through a first thermal energy transference path. The transfer of thermal energy to the thermal expansion unit causes expansion of the expansion material within the thermal expansion unit. The expansion of the expansion material causes an increase in length of the thermal expansion unit. The increase in length of the thermal expansion unit causes establishment of a second thermal energy transference path through which thermal energy is transferred from the expansion material to outside the thermal expansion unit.

摘要： An aircraft propulsion system includes a core engine assembly that generates an exhaust gas flow, a bottoming cycle that includes a bottoming fluid flow that is expanded through a bottoming turbine, a first heat exchanger where heat from the exhaust gas flow is transferred to heat the bottoming fluid flow, and a second heat exchanger where heat from a secondary heat source is transferred to heat the bottoming fluid flow. The second heat exchanger is disposed upstream of the first heat exchanger such that heat from the secondary heat source preheats the bottoming fluid flow prior to accepting heat from the exhaust gas flow in the first heat exchanger.

摘要： An engine includes a thermal unit, a force introducing unit applying a force to a shaft of the thermal unit in a first direction, and/or a switch assembly that switches between a first state and a second state. In the first state, the switch assembly transfers thermal energy from a source to the thermal unit, which causes the shaft to move in a second direction from a first position to a second position. The switch assembly switches to the second state (i) during movement of the shaft in the second direction, (ii) when the shaft reaches the second position, and/or (iii) when the shaft reaches a third position between the first position and the second position. In the second state, the switch assembly transfers thermal energy from the thermal unit to outside the thermal unit, which causes the shaft of the thermal unit to move in the first direction.

摘要： A system manages the reactions of fluids to their changes in their environment in order to convert these reactions into energy thereby harvesting the same while protecting the device against destruction or malfunction when the environmental conditions exceed predefined thresholds.

摘要： A capillary action propulsion system includes an absorbent material, at least one compression member, and a fluid. The absorbent material forms an endless path. At least one compression member compresses a portion of the absorbent material at a compression location. A fluid is disposed within the absorbent material in an unequal distribution with a first side of the absorbent material having more fluid than a second side. The absorbent material is configured to continuously rotate due to the at least one compression member compressing the portion of the absorbent material at the compression location causing the fluid to continuously remain unequally distributed within the absorbent material creating a weight imbalance in the absorbent material and a resulting moment. The fluid is configured to continuously rise, due to capillary action, within the absorbent material along the endless path from the compression location on the first side of the absorbent material.
