I have good news for the future of the MMC cap.
I think i mentioned that I had a demonstration of my coil at the Danish
Electricity Museum. Well, they offered me money, and I accepted: the Big
Blue is now a museum coil.
When it gets put into regular show schedule, with 3 - 4 shows per day,
we will see many hours of service put to the MMC cap of this coil, and
this, I think, will deliver valuable information about how reliable this
cap-consept really is.
