The key element Peltier module, a thermoelectric module have the ability to convert thermal energy into electrical energy. They are made of two unique semiconductors, one being p-type and another being n-type and they are static in nature. The working operation is based on Seebeck effect (conversion of heat into electricity) which occurs inside the Peltier modules. As the heat spreads and starts flowing so does the free charge carriers from the hot side to the cold side. The end voltages are proportional to the temperature difference and the system keeps on generating voltage as long as the temperature difference remain intact. Generated voltages from each Peltier module increases with respect to time and temperature difference. They are connected in series so that the end voltages will be high. The temperature keeps on changing so instability occurs which may damage the connected equipment so a chopper is connected before connecting the device to the system which provides pure and stable dc voltages. The device is not only useful for isolated areas but it can also be used in the industrial sector where latent heat is produced which can be used as the source of heating and extra amount of energy can be produced with it.
as forests and mountains is always doubtful because of various inconvenience caused by both the location and the atmosphere. Use of unconventional methods such as solar panels and generator when electricity is not reachable through transmission lines always clashes with nature in a way like dense forest areas and noise or air pollution due to generator in these areas so a suitable solution is needed. A device running on solid state devices like a Peltier module can be handy as there is no need of solar rays and it can provide a noiseless energy as per the need with very least use of sources and with less or zero effect on nature. These elements work on the Seebeck effect in which difference between two dissimilar electrical conductors or semiconductors produces a voltage difference between the two substances. Peltier modules can run on the latent heat generated by the candles or campfires and on the other side heat sink or chilled water/ice can be used for heat dissipation. By providing heating on one side and cooling on the other side a temperature difference is created which plays an important role in the voltage generation. Generated voltages can be high or low depending on the needs of the user and number of connected Peltier modules but it can be controlled and stabilized with the help of dc choppers.

1. INTRODUCTION Around 1.3 billion people live without electricity in the world and a quarter of them (300 Million) lives in India. Rural and isolated areas happen to be highly affected because of this and it will take a long time before the electricity reaches to them in normal ways through transmission and distribution system. The remotely isolated areas of forests and mountains do not have the reach to the electricity in many cases and hence an independent source of energy is necessary. The device made from Peltier modules try to provide energy by converting thermal energy into electrical energy. The sources of thermal energy are easily available around this places and their use does not affect the environment in a harmful manner. It is possible to run various devices used for lighting and other needs with the help of this device by converting the generated voltages with the use of various converters such as choppers and inverters.

Fig 1- Peltier modules connected in series Peltier Modules provide voltages using nothing but the heat emitted from various sources such as wood burning, candle flames, latent heat from industries, or the heat produced from the residential areas while cooking. The temperature difference created between the hot side and the cold side generates electricity. It can be highly useful in forest and mountain areas as well as in homes in case of power outages and in this situations we can use candle
