“…TEGs are generally used in power plants to convert waste heat into additional electrical power [9] and also in automobiles [10]- [12]. The latest developments of TEGs have also allowed this particular device to utilize human body heat to power up small devices [13] and heat from heat sink for electronics amplification [14], [15] .TEGs are also used in tandem with solar concentrator [16], [17] such as focal lenses (e.g. convex lens, bi-convex lens, fresnel lens, etc.)…”

<a name="OLE_LINK28"></a><a name="OLE_LINK27"></a><span>Electrical energy is important in various developments to ensure global stability. However, most electrical energy sources are non-renewable and these sources are expected to be depleted in the near future. In order to solve this problem, research on renewable energy sources are intensified and thermoelectric generator (TEG) is one of the potential solutions. TEG can generate electricity if the there is a temperature difference between the hot end and cold end of its plate and it is widely used in various applications, ranging from high temperature of a steam generator until to the lowest temperature of a human body. The initial development of this work focuses on the electrical power generator design by using focal lens to focus sunlight, a form of renewable energy, on the TEG hot end and also underground heat dissipation system on the cold end to create temperature difference. The initial results showed that the amount of power produced by the system is quite small but reasonable due to the type of TEGs used. However, the heat dissipation system showed a promising development due to its non-dependency on external energy to expel heat from the cold side</span><span>.</span>

“…A TEM is a static element with no moving parts, it is quiet and compact, highly reliable and environment-friendly [11]. There are different processes governing the physics of a TEM, that is, power conversion due to the Seebeck, Peltier and Thomson heating/cooling effects, Fourier heat transfer due to a temperature gradient and Joule heating generated by resistive components [12].…”

“…As long as current flows through the bus bar, the heat generated due to the Joule effect will be continuous, thus generating a temperature gradient between the bus bar and the ambient, which is exploited by the TEM to generate electrical power. In order to maximize the generated electrical power, a suitable heat sink is required, especially in low temperature gradient applications [12]. There exist many works focusing on this application for harvesting energy [13]- [16].…”
