Abstract
System and method for converting energy; the system comprising: an acoustic resonator; a phase-exchange device configured for forming across a section of said resonator a concentration gradient of a first substance in a gaseous medium contained by said resonator, to thereby generate a pressure wave within said resonator; and a conversion device for converting mechanical energy constituted by said pressure wave to non-mechanical energy.
Claims40
A method of converting energy, comprising:
- contacting a gaseous medium with a non-gaseous medium to increase concentration of a first substance in said gaseous medium and to release energy;
- directly converting a portion of said released energy to a pressure wave;
- and
- converting mechanical energy constituted by said pressure wave to non-mechanical energy.
A system for converting energy, comprising:
- an acoustic resonator;
- a phase-exchange device configured for forming across a section of said resonator a concentration gradient of a first substance in a gaseous medium contained by said resonator, to thereby generate a pressure wave within said resonator;
- and
- a conversion device for converting mechanical energy constituted by said pressure wave to non-mechanical energy.

A thermoacoustic system, comprising:
- a resonator having therein at least one thermoacoustic unit under a temperature gradient;
- and
- a phase-exchange device configured for forming across said thermoacoustic unit a concentration gradient of a first substance in gaseous medium contained by said resonator.
A system for converting energy, comprising:
- a resonator having therein at least one wet thermoacoustic engine under a temperature gradient, and a charged capacitor under generally constant voltage and/or having generally constant electrical charge, wherein said wet thermoacoustic engine is configured for generating a pressure wave within said resonator, hence also to vary an electrical capacitance of said capacitor in an oscillatory manner;
- and
- electric circuitry configured for extracting oscillatory current generated by said variation in said capacitance.
