Assessment of the effects of microwave‐produced biodiesel blends on electric generator performance and emissions

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Biodiesels are emerging as alternatives to diesel fuel. However, to be a feasible solution, biodiesels must meet strict criteria including high efficiency and minimal environmental impact. The current study focuses on evaluating ethyl ester biodiesel and its blends with diesel fuel to assess their potential.

Reuse of Pressurized Air in Ship Air-Lubrication Systems A Conceptual Improvement for Energy-Efficient Drag Reduction

open access: yes
Air-lubrication systems (ALS) reduce ship resistance by injecting compressed air beneath the hull to form a thin layer of bubbles between the hull surface and the surrounding water. Although these systems can reduce fuel consumption by approximately 5–10%, they require substantial compressor power, typically ranging from 500 to 2000 kW for large cargo ...
