Blue energy, harvested by controlling ion transport through nanopore membranes from high to low salt concentrations

"membranes from charged material, so nanopores cause current to flow through them by attracting solution ions with opposite charge, ions with same charge then move through pore generating current... instead of using membrane's basic surface charge, embedded gate electrode across membrane to control field through voltage, tuned selectively allowing cations to flow, leading to 6X increased osmotic energy efficiency... enhancing charge density at membrane nanopores' surface achieved 15 W/m2 power density... scalable"

Response received by email: "15 W/m2 power density, so a surface 100 m by 10 m would generate 15,000 W  or 15 Kw. Clearly a significant number if the effect can be scaled"
