Rolled Up Capacitors Have Double the Energy Density of Flat Capacitors

Maybe we should also think about how to improve capacitors. The size of capacitors doesn’t matter for focus fusion, but this might improve inductance and resistance, which does affect current rising time.

No question in my mind, we should always be looking for improved capacitors. Hopefully unity will make that a growth industry as well.

I thought most capacitors were rolled up anyway??? certainly if you look at any circuit board or power supply with cylindrical caps standing up on it they will be rolled up.

For better capacitor energy storage capacity you want to use something like Electric double-layer capacitors, which have a massively increased surface area.

But for our application they can’t handle the high voltages. To have a capacitor able to charge to 45kV without the dielectric material breaking down restricts your choice somewhat.

Tube B, or not tube B, that is the question.
Stacks of VISA cards?
Use muons instead! More bang for the buck.
