The increasing demand for energy across the globe today has put a strain on fossil fuels, the main resources of energy.
Despite intensive efforts in improving the efficiency and effectiveness of energy systems, energy issues remain the main
concern of developed and developing nations. Thermoacoustic technology is a new technology being explored; a
temperature gradient induced by acoustics and oscillations induced by a temperature gradient. A thermoacoustic heat engine
converts thermal energy into acoustic power while a thermoacoustic refrigerator/heat pump generates acoustic power from
an imposed temperature gradient. The working fluid is generally inert gases like Helium or mixtures of Helium and Xenon.
Since the first experiment by Byron Higgins in 1802 on oscillations produced by a hydrogen flame, investigations have
been done to study the practical applications of thermoacoustic effects in heat engines and heat pumps/refrigerators.
Feldman first reported a 27 W of acoustic power from 600 W of heat source in his Ph.D dissertation [1], with later
researchers investigating the theory that could explain the phenomena, possible optimizations and operations of actual
systems [2-10]. This study reports the experiments completed on a portable thermoacoustic heat engine that could possibly
be utilized with a cook stove to generate power. Past reported works on a similar purpose system have used an electrically
heated high temperature source which is manageable [11-13]. This study investigates the actual heat source that could come
from a combustion proces
