Scale Model WWII Craft Takes Flight with Fuel From the Sea Concept

The US Navy announced Scale Model WWII Craft Takes Flight with Fuel From the Sea Concept

Navy researchers at the U.S. Naval Research Laboratory (NRL), Materials Science and Technology Division, demonstrated proof-of-concept of novel NRL technologies developed for the recovery of carbon dioxide (CO2) and hydrogen (H2) from seawater and conversion to a liquid hydrocarbon fuel.

Fueled by a liquid hydrocarbon - a component of NRL's novel gas-to-liquid (GTL) process that uses CO2 and H2 as feedstock - the research team demonstrated sustained flight of a radio-controlled (RC) P-51 replica of the legendary Red Tail Squadron, powered by an off-the-shelf (OTS) and unmodified two-stroke internal combustion engine.

Using an innovative and proprietary NRL electrolytic cation exchange module (E-CEM), both dissolved and bound CO2 are removed from seawater at 92 percent efficiency by re-equilibrating carbonate and bicarbonate to CO2 and simultaneously producing H2. The gases are then converted to liquid hydrocarbons by a metal catalyst in a reactor system.

I'm not sure what the climate effects, if any, of this are but it's pretty amazing.
