Efficiency Problem of renewable energetics systems in the context of «smart house» concept

Abstract

Considering the question of efficiency of alternative energy systems, producing electricity from the position of interests of households it acquires an unexpected sound. The efficiency can be low (about 7-10%) providing that the heat released in converting is targeted i.e also used on the needs of households. In such an approach low efficiency becomes acceptable since the most part of energy usage in households is spent on systems using the heat (hot water supply etc.) even in the summer period. It is shown that converting of energy providing targeted heat dissipation can be provided by the phenomenon of generation of electromotive force by flowing of the low-speed, low-molecular salt current trough the polymeric sewed net; relevant experimental results are presented. Basing on the analysis of low-molecular ions currents balance by flowing of solution through the gel, the theory of the phenomenon is proposed. It is shown that the described phenomenon and based on its energy converting systems can be considered as an example illustrating the perspectivity of the new paradigm of green energetics development. Given paradigm is based on principles of technical and humanitarian knowledge convergence and is completely consistent with the conclusion that the environment-friendly technologies development is a technical and social issue at one time.

Prospects for the use of energy storage devices in the process of solar energy production

“…it increases energy resource integration by increasing the efficiency of energy systems and minimizing energy losses while reducing costs. In addition, energy storage separates electricity production from the load or the consumer of electricity, which facilitates the regulation of supply and demand, and also provides the ability to store energy in local networks, which in turn provides security guarantees (Suleimenov et al 2020). Tamme et al (2012) considered the main functions and prospects of energy-storage devices for thermal systems, where the design of thermal, energy-storage devices and their importance in the distribution and continuity of energy from the standpoint of environmental friendliness and efficiency are analyzed in detail.…”

Assessment of the Southern Urals Recreational Potential for the Development of the Aktobe Tourism Industry

“…Yerdavletov and etc. (Erdavletov, 2010;Ilies, 2010;Suleimenov, 2020;Dunets, 2020;Page, 2011). Recreational potential characterizes the extent to which the territory is able to meet the needs of the population in recreational activities.…”

Canyons of the Charyn River (South-East Kazakhstan): Geological History and Geotourism

“…Due to the physical and geographical location, the peculiarities of the geological and geomorphological structure and landscape diversity, the South Kazakhstan region has sufficient natural resource potential for the development of recreation and such types of tourism as ecotourism, "green" (agritourism), water tourism and other types. The works of the following scientists are devoted to the study of the landscape biodiversity of the geosystems of the South Kazakhstan region: Kulibaev (2006); Ilies and Grama, 2010;Suraganova (2013); Ilies et al (2017Ilies et al ( , 2018; Herman et al, 2019;Akbar (2020); Kerіmbay (2020); Indrie et al, 2020;Marcu et al, 2020;Suleimenov et al, 2020. Natural and recreational resources as a basis for the development of tourism and recreation are considered in the works of Akhmedenova (2017), Dunets and Zhogova (2019) and others.…”
