The current developments in the understanding of transport phenomena in the nanoscale have the potential to overcome the limitations of the traditional methods for osmotic energy harvesting.<br/><br/>This work summarizes observations made over various asymmetric single-pore molecular dynamics simulations, from conical to asymmetrically charged pores. We discuss the physical limits for optimizing the total power output, ionic selectivity, and ionic current rectification. We further analyze the effect of pore charge, pore size, and electrolyte concentration on the membrane's performance.<br/><br/>Beyond revealing the optimal solutions within the explored parameter space for the design of energy extraction pores, we will also emphasize the need for redefining many of the frequently used scientific terms that shape the discussions in this field.
