We cover aerodynamic theory (lift vs. drag, tip-speed ratio,…https://sguzman.github.io/marginalia/posts/desalination-plant-design-and-construction/Sat, 04 Apr 2026 00:00:00 +0000https://sguzman.github.io/marginalia/posts/desalination-plant-design-and-construction/Executive Summary: Desalination is rapidly growing to meet freshwater shortages, especially in arid regions. Modern desalination is dominated by membrane processes (chiefly reverse osmosis, RO) which now account for &gt;80% of global cap…https://sguzman.github.io/marginalia/posts/electric-motor-design-principles-types-and-practices/Sat, 04 Apr 2026 00:00:00 +0000https://sguzman.github.io/marginalia/posts/electric-motor-design-principles-types-and-practices/Executive Summary: Electric motors – devices that convert electrical energy to mechanical torque – are ubiquitous in modern engineering. Their history stretches from Faraday’s 1821 demonstration of electromagnetic rotation(https…https://sguzman.github.io/marginalia/posts/electric-motors-v2/Sat, 04 Apr 2026 00:00:00 +0000https://sguzman.github.io/marginalia/posts/electric-motors-v2/Electric motors have evolved from 19th-century experiments to today’s high-performance drives.
