Fig. 5: Performance measurements of the MHD drive in microgravity and terrestrial environments.
From: Magnetically induced convection enhances water electrolysis in microgravity
a, Variation of the angular velocity of the electrolyte with current density for both microgravity and terrestrial environments. Data are presented as mean values ± 2 s.d. of three independent measurements. b, Variation of the radial velocity of gas bubbles that showed steady-state behaviour (Methods) for different current densities and radial positions. The error bars represent the difference between the fit used for the radial position derivative (Methods) and the actual radial position ±2 s.d. c, Chronopotentiometric measurements of the MHD drive at 105 mA cm−2 indicate a very similar operation and efficiency in both terrestrial and microgravity environments. Data are presented as mean values ± 2 s.d. of three independent measurements.
