Lube oil generator gone

The lube oil generator that was shown in the Blip a few days ago has been removed.
The new one is already standing in the background.
The coupling and pick up of the revolutions (the grooved thing) are running in a mist of splattering oil, supplied by two small nozzles.
This is meant for cooling.
The oil is falling back in a kind of bin and flows back to the main lube oil tank.
