Your engine is truly fantastic; many people would be very interested in seeing a video or some photos uploaded here, on Discord or YouTube!
The technique using the membrane to curb the harmful Gideon streaming is very interesting; a few pictures would really help to understand it.
I believe many people also use a nozzle-shaped component (jet pump?) inside.
None of these measures are built into the current engine; I hope to minimise the harmful streaming through the design of the feedback loop combining inertia and compliance.
Rob and others are already working intensively with DeltaEC, and this can likely be taken into account in the calculations via integrated RPN modules.

These are really great results; some further information and pictures of your motor would be fantastic!
