Electric double-layer capacitors are a newish energy storage technology. I find them fascinating and I want to play with them.
Like a capacitor they can charge and discharge very quickly due to their low equivalent series resistance.
But supercapacitors store roughly two orders of magnitude more energy than normal capacitors!
I bought five 3000 farad, 2.7V Boostcaps:

I machined aluminum strips to form connecting bars. A 13.5 V series stack:

Awesome. One of my coworkers “didn’t believe” in supercaps and then I showed him your video.
Love it, especially to know you got good music to work with
Keep up the good work. I don’t know much about fusion, but I enjoy to follow your quest. Hope you’ll end up where you want.
