説明

<p>In snowy regions, a substantial amount of revenue is spent on snow removal. Snow removal is essential due to the risks it poses, such as traffic congestion and building collapses. Using a Stirling engine with snow as a low-temperature heat source can potentially achieve both snow melting and carbon neutrality. The Stirling engine operates based on expansion/compression phenomena when air is heated/cooled. It is known that the Stirling engine achieves higher thermal efficiency with larger temperature differentials. In this study, high-temperature sectionof the engine was heated with concentrated sunlight using Fresnel lenses so as to get higher temperature on that section. The results showed an average power generation of 173 W, and the exhaust heat from the engine could be used to melt the snow. The challenges identified include the need for continuous solar tracking for optimal power generation and the prevention of heat loss in the high-temperature section of the engine. We are planning to continue conducting further studies to achieve more efficient power generation and snow removal, moving towards practical implementation.</p>
