Abstract

The aim of this work is to obtain cheap and environmentally friendly fuels for automobile transport, as well as reducing emissions of harmful substances into the atmosphere with car exhaust. The problem can be solved by creating a system for producing technical hydrogen and its use in internal combustion engines and other power units. This article proposed using active metals, their alloys, or metal hydrides interaction with water to generate hydrogen. This proposal is based on an analysis of existing and possible methods of storing and transporting hydrogen. For the practical realization of this approach has been proposed the construction of the device of hydrogen storing and generating for powerful engines and vehicles. The functioning of the recommended equipment is to hydrogen generation by reacting the active metals, or their alloys, or metal hydrides with water in a polar aprotic organic solvent. From these products, it has been proposed to form the cartridges with internal through holes—cartridges placed in the hydrogen generator. The polar solvent pumped through the hydrogen generator in which it reacts with the material of the cartridge. At this solvent is added the water in a controlled manner and used for the reaction with the cartridge material for hydrogen release. Hydrogen, after separation of the liquid phase, flows into the fuel system of the internal combustion engine. The spent solvent is pumped into the solvent intake and storage system and, subsequently, the solvent is replaced when the cartridge is replaced. The system can operate in a closed-loop in the case organization of gathering and recycling of waste materials for reuse.

 

Keywords

Hydrogen, Hydrogen power, Hydrides, Hydrogen storage and generation, Aprotic polar solvents.

 

Introduction

Agency "Bloomberg" made a forecast of the development of world energy for the next 25 years and it is that "the energy structure of humanity will change forever," and it will happen soon.The essence of the changes can be explained in one phrase: fossil fuels will not withstand competition with renewable energy. First of all, it is solar energy and the issue ultimately rests on the power.1,2 The prospect of the exhaustion of hydrocarbon fuels, a large amount of pollution introduced into the environment during the operation of engines based on the combustion of hydrocarbon fuels, determines the relevance of developing technologies that use alternative energy sources. The most promising of these is hydrogen, the oxidation of which releases a large amount of energy and does not produce harmful substances. Hydrogen energy is a developing energy industry that is based on the use of hydrogen as a means of accumulating, transporting and consuming energy by people, the transport infra structure, and various industries. The development of this energy sector is associated, on the one hand, with a decrease in dependence on imported fuel, on the other hand, with requirements for improving the state of the environment. As you know, hydrogen is not found in nature in large quantities in the Free State, but it can be obtained by various technological methods. Firstly, hydrogen can be extracted from natural gas; secondly, it is produced by passing an electric current through water and in a whole number of different ways.

 Sustainable Development: Reality Or Myth? Since the United Nations Environment Conference in Stockholm (1972), the concept of sustainable development has steadily made its way among individual scientists and international organizations. The apotheosis of this development was the adoption by the United Nations in 2015 of the 17 Sustainable Development Goals. However, many scientists and politicians were skeptical about the concept of sustainable development, since the results of implementing sustainable development in different countries were far from expected. Many decisions taken at the level of the UN and other international organizations turned out to be unfulfilled. In my opinion, as well as some other Russian scientists, the concept of sustainable development is an unrealistic project, it is a myth, although it is very positive and humane. Sustainable development goals can be achieved only by the most economically developed countries entering the era of post-industrialism. In...

 How to Treat Cancer Properly Cancer is one of the deadliest diseases in the world, chemotherapy is effective under some conditions, but has too heavy side effects, and it is not effective to a considerable proportion of cases while the side effects are often life-threatening, drugs (not unhealthy addictive drugs mentioned in reference four, the drug in reference four only mean those makes people addictive but does no good to health, destroying health quickly) are not always available to improve the condition. However, sport is a potential treatment that is effective to cancer before the cancer is disseminated, this gets little attention but is true both in theory and practice. The physical activities that have moderate intensity and duration should have devastating effects on cancer cells, they make the body hot and reduce the nutritional resources that cancer cells can get, also renew the proteins in the body and improve one’s mood, cancer cells are hard to live when one is activ...

 From Bronchial Asthma to Tuberculosis: Unravelling the Cytokine-Macrophage Axis in Diverse Diseases Cytokines, tiny proteins secreted by cells, play a critical role in mediating communication and interactions between cells. They also function as immunomodulating agents, adjusting immune responses. When released into the bloodstream or tissues, cytokines bind to specific receptors on target immune cells, triggering cellular responses. Cytokines are implicated in various diseases, including asthma, COPD, HIV infection, and multiple sclerosis. This review delves into the intricate interplay between cytokines and macrophages, focusing on their roles in inflammation and the immune response. Macrophages, which are scavenger cells of the immune system, exhibit remarkable heterogeneity, reside in diverse tissues, and play crucial roles in both innate and acquired immunity. They can be activated for proinflammatory or anti-inflammatory functions, contributing to tissue destruction or regen...
