Abstract
A looped tube type thermoacoustic prime mover with multiple regenerators driven by pressurized steam is being constructed. The pressurized steam is produced within a container filled by water which is boiled by an immersion electric heater. The steam is then let to flow t the hot heat exchangers of the thermoacoustic prime mover. The maximum pressure and temperature of the steam can be increased by adding extra water into the container when most of initial amount of water has changed to steam. The thermoacoustic prime mover with one to four regenerators will be tested. After laboratory test, we plan to realize a thermoacoustic prime mover driven by natural heat, by replacing the immersion electric heater with concentrated sunlight, and by utilizing steam from geothermal well.
