Today rates of own production don't meet the increased needs of the population and don't promote saturation of the markets domestic production that threatens food and national security in general. In such conditions extremely important are problems of import substitution, replacement of the imported goods due to revival and development of the domestic production of the food industry which is turning out competitive products. Need of cardinal increase in competitiveness of the Russian enterprises and expansion of domestic production of the food industry impose requirements to serious reorganization of state policy of import substitution.

The performance of a vibration power generator using a single crystal core of Fe–Ga alloy was compared with that of a generator using a Fe–Ga alloy polycrystal core with a similar Ga concentration. When the generator using the polycrystal core was forcibly vibrated by 1-G acceleration, the vibration frequency dependence of the open-circuit voltage showed a peak with a maximum value of about 0.14 V at the first resonance frequency due to the inverse magnetostrictive effect. On the other hand, the generator using a single crystal core with a <100> direction parallel to the external stress direction exhibited a maximum value of about 0.26 V, about two-times larger than that of the device using the polycrystal core. Consequently, a vibration energy generator using a single crystal core of Fe–Ga alloy has advantages in performance over a generator using a polycrystal core.

The growing demand of diesel power generators in Iran has led to air pollution. Hence, it is necessary to ascertain the level of performance and emissions of the diesel power generators fueled with biofuels. For the first time, in this study, the effect of biodiesel from waste cooking oil and diesel fuel blends (B0, B20, B50, B80 and B100) on the performance (brake power, brake torque, BSFC, brake thermal efficiency and exhaust gas temperature) and emission characteristics (CO and NOx) of a diesel power generator model CAT3412 was investigated. The experiments were conducted at rated engine speed 1530 rpm and various engine loads (25%, 50%, 75% and 100%). The results of the study showed an increase in brake power, brake torque, BTE and NOx emission and a reduction trend in BSFC and CO emission at higher engine loads for all the biodiesel-diesel blends. In addition, the research results indicated that B20 and B50 fuel blends in terms of performance emission characteristics could be recognized as the potential candidates to be certificated for usage in the diesel power generator.

Abstract In order to realize a small-sized energy harvester with high output, this study prototypes a small motor-driven gyroscopic power generator. Supplying energy to sensors and devices is the biggest problem for Internet of Things (IoT) systems. One solution is gyroscopic power generators, which are a type of vibrational generator that amplify the inertia force of weights by rotating them at high speed, and in doing so can obtain greater output than conventional generators that use simple vibration for the same mass weight. This paper reports on a motor-driven type gyroscopic generator in which the flywheel is spun with an embedded motor, and which is superior in applicability to random vibration generators. The generators of this type that have been studied thus far are very large and have been primarily used for wave power generation in the ocean. However, when the shape of this gyroscopic power generator type is miniaturized proportionally, the output per volume decreases in proportion to the fifth power of the dimension. This makes it difficult to maintain the power output while miniaturizing the generator size. In this research, the structure of the gyroscopic power generator is thoroughly refined and miniaturization is realized by making full use of the available space. By using a motor with high design freedom, the spindle motor and flywheel are unified. From this accomplishment, not only is the required space reduced, the number of mechanical parts and the friction loss are decreased as well. The prototype generator has a size of about 150 mm on its long side. When a swinging vibration of 50 degrees in amplitude and 2 Hz in frequency is applied, a net output of 0.104 W is obtained. This output power is sufficient to drive sensors and low power wide area (LPWA) radio circuits.

AbstractPaper is a material with a high Young’s modulus that vibrates sensitively due to environmental noise, voice, and sound. This study aims to create a triboelectric power generator to convert this sonic vibration energy into electrical energy to power microelectronics embedded on paper. A sonic wave has two wave modes, transverse and longitudinal, that propagate in paper; therefore, two types of triboelectric power generators were designed for trial simulation as the first step. A triboelectrically charged polytetrafluoroethylene sheet and a back electrode were attached to a paperboard. Another paperboard with a counter electrode attached was vibrated in the out-of-plane direction corresponding to transverse waves such that it would repeatedly move toward and away from the other paperboard. The generated power between the two electrodes reached 11.8 µW at 2 MΩ load. When comb-shaped electrodes were applied, manual strokes in the in-plane direction, corresponding to a longitudinal wave, induced voltage up to 8.2 V. The result suggested that sonic waves could be an electric power source for microelectronics in the future.
