The World

As the world is changing and developing with every passing day, the requirements of power are also increasing. There is a shift in utilizing the electrical energy as much as possible and for this reason, many countries have already made policies for completely ruling out the machines which don’t run on electricity. Apart from electricity, there are other forms of energy that can be used to convert that form into a more desirable form. For example, in a plant where the smoke comes out of the chimneys or in a car, the smoke carries a large amount of thermal energy with it. This energy is nothing but a waste and reduction in the efficiency of the systems. If somehow, this energy could be recovered, the efficiency can be increased. Thermoelectric generators serve for this purpose. Thermos electric generators get the heat and using the principle of heat conduction and p and n type materials, the heat can be directly converted into the electricity. There are many materials available in the market for p and n type but in our case, we chose silicon germanium which is also one of the most commonly used. First of all, a single module of thermoelectric generator will be made using p and n type material, as well as using conductive material and some ceramic substance. Then, the entire assembly will be made and this assembly will be exported to Ansys where custom materials will be added and applied on to the geometry. After performing analysis on full model, a comparative study will be presented in which the effect of material of conductive plate on to the voltage difference will be studied

<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>

The thermoelectric generator (TEG) has long been used to produce electrical energy where when a temperature difference occurs between two different semiconductor materials, this thermoelectric element will produce a voltage difference and flow an electric current. This principle is known as the 'Seebeck effect'. This research was conducted to determine the electrical energy potential of the TEG module as an alternative energy source by utilizing chimney heat from an incinerator. The test was carried out with a variation of 1, 2 and 3 m chimney height with treatment without compaction and compaction of waste. The test results show that with 12 TEG modules arranged in series electricity can produce an output voltage with a maximum temperature difference of each ΔV 3,31 Volt ; ΔT 15,0 °C (1 m), ΔV 3,92 Volt; ΔT 17,8 °C (2 m), ΔV 4,84 Volt ; ΔT 22,0 °C (3 m) while the compaction of each value ΔV 6,34 Volt ; ΔT 29,2 °C (1 m), ΔV 7,69 Volt ; ΔT 35,2 °C (2 m), ΔV 9,09 Volt ; ΔT 41,5 °C (3 m). The potential power that can be produced is as big as 3,22 W (1 m); 4,56 W (2 m); 6,88 W (3 m) while the compaction of waste is equal to each value 11,80 W (1 m); 17,36 W (2 m); 24,25 W (3 m). The addition of chimney height variation resulted in an increase in the hot side temperature (Th), cold side (Tc) and temperature difference (dT) so that heat energy and power energy increased.
