First Time

A thermoelectric generator (TEG) converts thermal energy to electricity using thermoelectric effects. The amount of electrical energy produced is dependent on the thermoelectric material properties. Researchers have applied nanomaterials to TEG systems to further improve the device’s efficiency. Furthermore, the geometry of the thermoelectric legs has been varied from rectangular to trapezoidal and even X-cross sections to improve TEG’s performance further. However, up to date, a nanomaterial TEG that uses tapered thermoelectric legs has not been developed before. The most efficient nanomaterial TEGs still make use of the conventional rectangular leg geometry. Hence, for the first time since the conception of nanostructured thermoelectrics, we introduce a trapezoidal shape configuration in the device design. The leg geometries were simulated using ANSYS software and the results were post-processed in the MATLAB environment. The results show that the power density of the nanoparticle X-leg TEG was 10 times greater than that of the traditional bulk material semiconductor X-leg TEG. In addition, the optimum leg geometry configuration in a nanomaterial-based TEG is dependent on the operating solar radiation intensity.

This type of research is development research (R &amp; D). This research was conducted at SDN Nguwet Kranggan, Temanggung Regency, Central Java, with a research subject of 35 class V students. The research instrument used in this study was a questionnaire. Questionnaires were filled in directly by respondents and validated by experts. The respondents who filled out the survey were teaching material experts, learning tool experts, and students. Data analysis techniques in this study used descriptive analysis. The results of this study are that Media Pop-Up developed is a Pop-Up folk tale or legend by linking local story elements in Temanggung Regency. This is due to the developed Pop-Up Book media based on local wisdom so that relevant stories are chosen, namely the Sindoro Sumbing Legend. Pop-Up Media Legend of Sindoro Sumbing based on domestic intelligence was developed with stages (1) research and data collection, (2) product manufacturing planning, (3) product draft development, and (4) limited implementation test. The results of the implementation tests in schools include individual tests, limited, and extensive tests obtaining scores in a row 4.25; 4.48; and 4.77, which means that the Pop-Up Legenda Sindoro Sumbing media is worthy of being used as a media for student literacy.</p>

The Relationship

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.

Turbo Generator

The performance of turbo-generators significantly depends on the design of the power turbine. In addition, the thermoelectric generator can convert waste heat into another source of energy. This research aims to design and optimize an integrated turbo-generator and thermoelectric generator for diesel engines. The goal is to generate electricity from the vehicle exhaust gas. Electrical energy is derived from generators using the flow, pressure, and temperature of exhaust gases from combustion engines and heat-waste. In the case of turbo-generators and thermoelectric generators, the system automatically adjusts the power provided by an inverter. Typically, vehicle exhausts are discarded to the environment. Hence, the proposed conversion to electrical energy will reduce the alternator charging system. This work focuses on design optimization of a turbo-generator and thermoelectric generator for 2500 cc. diesel engines, due to their widespread usage. The concept, however, can also be applied to gasoline engines. Moreover, this model is designed for a hybrid vehicle. Charging during running will save time at the charging station. The optimization by variable van angles of 40°, 50°, 62°, 70°, and 80° shows that the best output power is 62°, which is identical to that calculated. The maximum power outputted from the designed prototype was 1262 watts when operating with an exhaust mass flow rate of 0.1024 kg/s at 3400 rpm (high performance of the engine). This research aims to reduce fuel consumption and reduce pollution from the exhaust, especially for hybrid vehicles.

Buying In

As the Internet grew and evolved, it became more widely used by everyone. What once was utilized by the military and used for academic purposes is now employed by companies for e-business marketing strategies and alliances in the supply chain. Historically, companies have found many ways to work together, playing different roles with regard to manufacturing, supplying, selling, delivering, and buying in the supply chain. Most of the time, according to role, members of each company get together in a shared space (i.e., marketplace) to work on a particular project (i.e., delivering quality goods or services to customers). The emergence of the Internet has brought an appropriate media to expand markets and enable collaboration with partners in all stages of product manufacturing, testing, and delivering through electronic commerce. Support for these collaborations over the Internet, called e-coalition here, is what this chapter is about.
