​I just wrapped up a rigorous 36-hour continuous constant-power (0.5W) endurance test on the 1st-gen LGOOO Power Core — a 300mL 3D-printed modular reaction chamber powered by a magnesium alloy anode and an air cathode, running on 7% saline solution.

Only ~12% of the magnesium alloy anode was consumed during this entire 36-hour test!
