Solar driven thermoacoustic refrigerator

A system comprising:

• a first thermoacoustic device comprising:
• a collector configured to collect energy from an energy source;
• a waveguide configured to receive the energy from the collector;
• a thermoacoustic engine (TAE) within the waveguide configured to convert the energy into an acoustic wave;
• a thermoacoustic refrigerator (TAR) within the waveguide configured to convert the acoustic wave into thermal energy;
• and
• a fluid network including a conduit that has a fluid, wherein the fluid is configured to exchange the thermal energy with the TAR.

A method comprising:

• receiving, at a waveguide, energy;
• converting the energy into first thermal energy within the waveguide;
• converting the first thermal energy into an acoustic wave within the waveguide;
• converting the acoustic wave into second thermal energy within the waveguide;
• and
• directing the second thermal energy to a substance.
