Comparison of Power and Thrust Performance for a Fixed and Floating Offshore Wind Turbine

Wind Energy, Volume 29, Issue 6, June 2026.
ABSTRACT Floating offshore wind turbines have been identified as a critical technology for sustainable electricity generation. Wind resource assessment is used to determine optimal locations for floating wind farms. However, current methodologies do not account for performance differences between fixed and floating turbines due to wind‐ and wave ...

Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance

Bed rest decreases resting skeletal muscle O2 uptake and resting energy expenditure in young and elderly subjects

Experimental Physiology, Volume 111, Issue 5, Page 2599-2612, 1 May 2026.
Abstract A decrease in resting muscle O2 uptake (V̇O2m${\dot V_{{{\mathrm{O}}_2}{\mathrm{m}}}}$) described during bed rest (BR) could determine a decreased whole‐body resting energy expenditure (REE), potentially useful during prolonged spaceflights. Two groups of recreationally active men (young [Y], n = 8, age 23 ± 5 years; elderly [E], n = 10, age ...
