The prototype of the electric smart stove is an electric stove with briquette fuel from teak leaf waste. The thermoelectric module used is 12 units of a Peltier TEC-12706. Thermoelectric generators take advantage of the Seebeck effect with temperature differences from both sides of the Peltier will produce electrical energy. The developing prototype method of an electric smart stove is carried out in 4 stages. First stage, analyzing geometry requirements and smart stove shape. Second stage is the process making of an electric smart stove. Third stage, installation of a power plant. The fourth stage, measurement of electrical power output. Based on the experiment, it is found that the thermoelectric generator produces 1.31 volts of electrical energy with a delta T of 40 degrees Celsius. As the result, an electric smart stove has not been able to charge the battery because the electric energy produced tends to be small.

Solar pond is one source of renewable thermal energy. The solar pond collects and stores thermal energy at the lower zone of the solar pond. The temperature at the lower zone can reach up to 90 °C. The solar pond is capable storing thermal energy for a long period. The stored thermal energy can be converted into electricity by using thermoelectric generators. These thermoelectric generators can be operated using the cold and hot zones from a solar pond. In this paper, the experimental investigation of power generation from the solar pond using thermoelectric generator and simple heat exchanger is discussed. A maximum of 7.02 W of electrical power output was obtained from a simple heat exchanger with 40 thermoelectric modules.

Thermoelectric generator is solid-state device which convert temperature difference, ∆T into electrical energy based on Seebeck effect phenomenon. The device has been widely used in self-powered system applications. This paper focuses on presentation of methodology for characterizing thermoelectric generators. The measurement of its behavior is performed by varying load resistances. A standard module of thermoelectric generator (TEC1-12710) is used in examination and an instrument setup consists of controllable heat source, controllable cooler, personal computer, data logger MCC DAQ USB-1208LS equipped with two sets of K-type thermocouples. The experiment is performed by measuring output voltage and output current in 4 values of temperature gradient by applying 10 values of resistive loads connected to the thermoelectric output wires. The common parameters studied in this research are output voltage, current and power. Generally, the relationship between parameters agrees with the basic theory and the procedure can be adopted for characterizing other type of thermoelectric generator.

In this paper, the author compares chromatic terms in Ruthenian and Serbian. He focuses on the basic colour terms according to Berlin and Kay: white, black, red, green, yellow, blue, brown, purple, pink, orange, and grey. They have equivalents in both languages: Ruthenian bila – Serbian bela, čarna – crna, červena – crvena, željena – zelena, žovta / žolta – žuta, belava – plava, braon – braon, lilova – ljubičasta, celova – roze, pomarančecova /poma- randžecova – narandžasta, šiva – siva. The criterion of one-morpheme word is not appli- cable to the terms lilova, celova, and pomarančecova /pomarandžecova in Ruthenian, and ljubičasta and narandžasta in Serbian. It is applicable to the terms bila, čarna, červena, željena, žovta / žolta, belava, braon, and šiva. With the exception of braon, all these terms are derived from the Proto-Slavic language (*bеlъ, *čьrnъ, *čьrvenъ, *zelenъ, *žltъ, *polvь, and *sivъ). As far as the Berlin–Kay’s universal of seven phases of colour formation is con- cerned, our study of chromatic terminology confirms it. In accordance with the supposed first stage of development, the Ruthenian language has bila and čarna; according to the second stage, Ruthenian has červena; in accordance with the third stage, Ruthenian has že- ljena or žovta / žolta; according to the fourth stage, Ruthenian has žovta / žolta or željena; in accordance with the fifth stage, Ruthenian has belava; according to the sixth stage, it has braon; and in accordance with the seventh stage (even if we leave aside the multi-mor- pheme terms lilova, celova, and pomarančecova /pomarandžecova), it has šiva. Generally speaking, the usage of the terms is identical in both investigated languages but there are several differences (e.g. cibulja – beli luk, željena pasulja – boranija). The most frequent suffixes are -asta and -ista in Ruthenian, and -asta in Serbian.Most of the chromatic terms are of Slavic origin but there are several borrowings used for nuance purposes in recent decades, e.g. azurna, teget, akvamarin, tirkizna, and others. Some borrowings remain unchanged, e.g. in both languages blond, braon, drap, krem, bež, and oker, and only in Serbian lila and roze. Hungarian was the official language until the first decades of the 20th century (until the collapse of the Austro-Hungarian Monarchy in 1918), during which Ruthenian–Hungarian bilingualism reigned. That is the reason why several Hungarian colour names are found, e.g. in surnames (the Ruthenian surname Barna comes from Hungarian barna ‘brown’, Fekete/Feketa is from fekete ‘black’, and Vereš is from vörös ‘red’) and in the names of domestic animals (the Ruthenian horse name pejka [Serbian riđan] comes from Hungarian pej ‘brown’ and šarga [Serbian žutalj] is from sár- ga ‘yellow’). The general name for ‘colour’ comes from the German language (Ruthenian farba is from German Farbe).

Abstract Solar air heater is a promising, economically viable, and matured technology for space heating and drying applications. One of the primary reasons for the limited usage of a solar air heater in developing countries is the unavailability of continuous electricity supply. Although the solar air heater is theoretically passive, practically electrical energy is required to achieve a steady airflow. Therefore, the unreliability of electricity forces people to rely on firewood for heat during the cold weather, which has severe effects on health and climate change. In the present work, the potential of thermoelectric generators (TEGs) to meet the electrical energy requirement of a solar air heater is studied. Two configurations, each with three different numbers of stages of TEGs, are analyzed. The effect of the integration of TEGs on the thermal performance of solar air heater is analyzed alongside the comparison between the electrical energy required by solar air heaters and electrical energy generated upon the integration of TEGs. A numerical model is developed in matlab and validated using the experimental results. One of the designs meets the electrical energy requirement of the fan in a wide operational range but lowers the process heat generation by approximately 1–6.25%. The electrical energy generated by the other design falls short of demand posed by the system in most operating range. However, the thermal energy generation is marginally higher compared to that of the conventional solar air heater.

All photovoltaic panel heats up when exposed to sunlight and this heating reduces the electrical power output of the same. This work presents the use of this unwanted waste heat, converting it into thermal energy directly by means of the Seebeck effect, which is the direct conversion of thermal energy into electrical energy by means of an arrangement of semiconductor materials that when exposed to temperature gradients generate electric current. In this work emphasis was placed on the influence of temperature on generation processes involved. Thus, the theoretical evaluation, it presents the mathematical models of thermoelectric and photovoltaic systems by raising the curves of voltage, current and electric power generated, and analyses the influence of temperature in each model. To obtain the simulation curves it uses MATLAB ® 5.3, taking into account the parameters of thermoelectric modules and real photovoltaic cells. In practical evaluation, a prototype was assembled containing thermoelectric module attached to the bottom of a photovoltaic panel in order to use the heat energy absorbed by the panel. The data were stored and analyzed, where we observed the influence of temperature in both systems, validating the mathematical modeling. It is the applicability of the mathematical model given the results obtained with the prototype system.

So far, methods of dating fossil objects have allowed us to obtain a large amount of data that characterize the moisturization of our planet’s areas during different time intervals. At the same time, in some cases, fossil objects contain information about the characteristics of the climate of the epoch of their existence. The available dating is scattered and does not allow us to get an overall picture of the changes occurred. Therefore, the developed method of aggregate representation of dates is relevant. Scientific materials containing the desired dating are mainly presented on the Internet. Therefore, the target of the first stage is to identify the publications of interest. At the second stage, the dating found and its characteristics are summarized in table 1. At the third stage, the data in table 1 is converted to table 2, reflecting the change in the moisture content of regions with a 100 years sampling interval. At the fourth stage, a simple rule is applied to exclude two multidirectional trends in each cell of table 2. As a result of exclusion, only unidirectional signs remain in each cell that qualitatively characterize the moisture content of the studied regions. It seems that the dating found in a significant minority should be questioned. However, cases in which the number of exceptions exceeds the number of non-excluded characters require additional research. The proposed method is not limited either by the number of studies involved or by the dating methods used. The scientific novelty of the proposed method consists in the aggregate representation of known dating of fossil objects containing information about the characteristics of the climate of the epoch of its existence. The objectivity of the results obtained is based on the use of a variety of independent dating of fossil objects obtained by different methods for different periods and regions. The reliability of the results obtained will increase with the number of dating involved in the analysis.

The need for energy consumption nowadays becomes very important things, especially the need for electrical energy. Technology to convert heat into electricity directly can be realized using thermoelectric generators. To know the thermoelectric generator performance, this study performs an investigation of thermoelectric generator operated using motorcycle exhaust heat to generate DC power. Three identical thermoelectric generators model TE-MOD-5W5V-35S were used in this investigation. To generate different high temperatures the motorcycle was run at 1600 rpm, 2100 rpm, 3100 rpm. The circuits examined were series, parallel and combination of the two. All data were recorded using DAQ MX 9714 NI data logger that was connected to the PC using LabView program. The loads used in the current measurements were a thermoelectric cooler module model SP1848 and a fan 12 V - 0.13 A. Those two loads were installed in a parallel circuit. The results show that the tests without load produce the highest voltage, while the tests with the load result in the highest power. Increasing the temperature difference increases the power, and the parallel circuit results in the biggest power but the lowest voltage. The highest voltage of 3.3 V with series circuit was attained, and the highest power of 0.133 W with a parallel circuit was also obtained.

The increasing demand for electrical energy in Bali requires additional electrical energy supply, while conventional energy such as petroleum, coal and natural gas continue to be used. Therefore, the utilization of non-conventional energy like solar energy should be increased. One of provision of non-conventional electric energy which is ready to be widely used is using PLTS Photovoltaic technology. The data analysis in this study uses manual calculation method to calculate electric power requirement, setting the result for electrical power, calculating the amount and capacity for solar module and inverter, calculating slope angle and location of solar module. PLTS uses a hybrid system with PLN, which works automatically to be controlled by the inverter control system. PLTS capacity of 148,274 kW supply 30% of the electrical energy consumption in the building of 2,310 MWh.
