"Manufacturing Cost Data on Artificial Ice" by Otto Luhr and Herman Friedl is a scientific publication likely written in the early 20th century. The book focuses on the manufacturing processes and cost analysis involved in producing artificial ice, providing detailed information on the efficiency and economic feasibility of ice production methods compared to natural ice harvesting. The text presents a comprehensive breakdown of costs associated with manufacturing artificial ice, including labor, power, and maintenance expenses, demonstrating significant savings by utilizing an advanced ice-making system. Luhr and Friedl emphasize the advantages of their methodology, which promises to lower labor costs and enhance sanitary standards, ultimately suggesting that widespread adoption could replace natural ice in commercial usage. The systematic explanation of cost components, alongside practical insights into operational efficiency, aims to inform potential investors and entrepreneurs in the ice production industry on the viability of artificial ice manufacturing.
