The solar energy collection used to power a thermoacoustic prime mover has been calculated. The solar energy is concentrated by a Fresnel lens into a water-filled thermal storage container to produce pressurized hot steam which is then supplied to sealed-off hot exchangers of a thermoacoustic prime mover. We consider collecting the solar energy in Yogyakarta, Indonesia in where the average energy of solar global radiation of 4.8. kWh/m^2/day (17.3 MJ/m^2/day) is available around the year. The calculations include the amount of the remaining heat stored, steam pressure, and water/steam temperature, and were done for various lens area and water volume as a function of time for several days. We found that appropriate combinations of lens area and water volume enable us to operate the prime mover continuously all day and night.
