Drag-mode airborne wind energy vs. wind turbines: An analysis of power production, variability and geography
TLDR
In this article, the performance of AWE systems relative to traditional wind power turbines (WT) is compared to the hourly power production of classical WTs, and the results show that AWE system with multiple smaller wings have the highest annual production.About:

Significance of diffusion layers on the performance of liquid and vapor feed passive direct methanol fuel cells
TL;DR: In this article, the effect of surface morphology, structure, permeability of diffusion layers (PTFE-treated carbon paper (CP) or carbon cloth (CC)) on the catalyst utilization, methanol, water fluxes, Faraday efficiency, and current discharge in pDMFCs were investigated in liquid and vapor feed pDMfcs.

Computing the power profiles for an Airborne Wind Energy system based on large-scale wind data
TL;DR: This paper proposes a method how to reduce the computational effort when using an OCP for power computations of large-scale wind data, based on homotopy-path-following strategies, which make use of the similarities between successively solved OCPs.
