There are about seventeen sustainable development goals (SDGs) such as (1) no poverty, (2) zero hunger, (3) good health and well-being, (4) quality education, (5) gender equality, (6) clean water and sanitation, (7) affordable and clean energy, (8) decent work and economic growth, (9) industry, innovation, and infrastructure, (10) reduced inequalities, (11) sustainable cities and communities, (12) responsible consumption and production, (13) climate action, (14) life below water, (15) life on land, (16) peace, justice, and strong institutions, and (17) partnerships.</p><p>As energy is the key to achieve every other 16 SDGs, it is apt to mention the potential of distributed electricity generation and the engineering challenges in achieving SDG 7 about affordable and clean energy. In distributed electricity generation, a biogas-fired micro-gas turbine (MGT) generator with an output from 5 kW to 500 kW is one of the options. With the concept of the agro-energy complexes, efforts are being made in European countries to integrate biogas production from agricultural farm wastes and electricity generation using MGT. The development of an MGT requires the design and precision manufacturing of tiny radial compressors and turbines that are efficient against tip leakage. To improve thermal efficiency, MGTs are equipped with exhaust gas heat recuperators. To increase the temperature of gas at the entry to the turbine, cooling systems are to be developed. MGTs drive the Permanent Magnet Alternators (PMAs). PMAs generate electricity at a frequency in the range of a few kHz equivalent to the speed from 50000 RPM to 100000 RPM of the MGTs. Using solid-state power electronics, the unsteady electrical power in the range of a few kHz is converted into steady electrical power from 380 V to 480 V and from 40 Hz to 60 Hz grid frequency. High-speed air bearings are necessary to support the rotor. In distributed electricity generation where an MGT is used, air bearings can be a reliable option for extending the service time between overhauls. The major obstacle to the application of air bearings is the phenomenon of a self-excited whirl. During the air-bearing design, research efforts are being made to analyze and evaluate this kind of dynamic instability.</p><p>This international conference aims to focus on such engineering challenges for attaining the aforementioned global sustainable development goals of the United Nations. It is my pleasure to invite you all to participate in the deliberations that address engineering challenges in access to affordable food, clothing, shelter, energy systems, and education, climate change, biodiversity, pollution, jobs and social protection, and digital connectivity.</p> </div> </div> </div> </div> </div> </section> <section class="elementor-section elementor-top-section elementor-element elementor-element-a0a41ec elementor-section-boxed elementor-section-height-default elementor-section-height-default" data-id="a0a41ec" data-element_type="section"> <div class="elementor-container elementor-column-gap-default"> <div class="elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-1262094" data-id="1262094" data-element_type="column"> <div class="elementor-widget-wrap elementor-element-populated"> <div class="elementor-element elementor-element-6f5a91b elementor-widget elementor-widget-heading" data-id="6f5a91b" data-element_type="widget" data-widget_type="heading.default"> <div class="elementor-widget-container"> <h2 class="elementor-heading-title elementor-size-default">Media Partner</h2> </div> </div> </div> </div> </div> </section> <section class="elementor-section elementor-top-section elementor-element elementor-element-7901d92 elementor-section-boxed elementor-section-height-default elementor-section-height-default" data-id="7901d92" data-element_type="section"> <div class="elementor-container elementor-column-gap-default"> <div class="elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-90192cd" data-id="90192cd" data-element_type="column"> <div class="elementor-widget-wrap elementor-element-populated"> <div class="elementor-element elementor-element-ca03612 elementor-widget elementor-widget-image" data-id="ca03612" data-element_type="widget" data-widget_type="image.default"> <div class="elementor-widget-container"> <a href="https://allconferencealert.net/eventdetails.php?id=2687404" target="_blank"> <img loading="lazy" decoding="async" width="1024" height="202" src="https://icecgsd2025.psncet.ac.in/wp-content/uploads/2024/08/All-conference-alert-1024x202.png" class="attachment-large size-large wp-image-2282" alt="" srcset="https://icecgsd2025.psncet.ac.in/wp-content/uploads/2024/08/All-conference-alert-1024x202.png 1024w, https://icecgsd2025.psncet.ac.in/wp-content/uploads/2024/08/All-conference-alert-300x59.png 300w, https://icecgsd2025.psncet.ac.in/wp-content/uploads/2024/08/All-conference-alert-768x152.png 768w, https://icecgsd2025.psncet.ac.in/wp-content/uploads/2024/08/All-conference-alert-1536x303.png 1536w, https://icecgsd2025.psncet.ac.in/wp-content/uploads/2024/08/All-conference-alert-2048x405.png 2048w" sizes="(max-width: 1024px) 100vw, 1024px" /> </a> </div> </div> </div> </div> </div> </section> </div> </div> </article> </div> </div> </div> </main> <footer id="footer" class="site-footer" itemscope="itemscope" itemtype="https://schema.org/WPFooter" role="contentinfo"> <div id="footer-inner" class="clr"> <div id="footer-bottom" class="clr no-footer-nav"> <div id="footer-bottom-inner" class="container clr"> <div id="copyright" class="clr" role="contentinfo"> Copyright 2024 漏 Mechanical Engineering Department - PSN College of Engineering & Technology </div> </div> </div> </div> </footer> </div> <div style="display: none;
