We fired the mini MHD generator for the third time today. We’re firing it with one sensor at a time to debug the unit. We got data across the run, but at lower than expected values. The smaller motors seem to foul the anode and cathode more the the larger motors do. Perhaps the larger motor scrub the inside of the generator while it’s running. We’re still getting separation of the anode and cathode from the ceramic walls.
Need more testing…
