This kind of construction could be adapted to making Spiral Generators (a.k.a. "Vector inversion generators"), except that longer strips of Mylar would be required. Here are some references:

More on that can be found at:
"There are 2 basic, different, ways of winding our type of capacitor, know as "insert tab" and "extended foil".
With the "insert tab" type of winding, a small, tinned copper, tab is laid into the winding at a pre-determined number of turns, one or more on each of the foils; the foils are wound directly over each other, separated by the film, and the film is wider than the foil, to permit an "edge space" appropriate to the voltage rating.
The "extended foil" type is wound similarly, but the foils are offset, so that 1 foil protrudes from 1 edge of the section, the other foil from the opposite edge. Ultimately, the ends will be soldered over. This provides much lower self inductance in the capacitor and enables it to discharge huge peak currents. . . even over 100,000 amperes! Such currents are common in radar systems and can occur in fault situations in almost anything that can short out an unprotected capacitor, accidentally. Note that current is also limited by internal wiring!"

I had excellent success constructing a 200,000 volt capacitor from a length of PVC pipe. See
I have never tried making a Marx generator out of these but I believe it could be done. Has anyone perfected a PVC water resistor?
Also, I would like to see more applications of the HV knowhow. Making sparks is fine, as far as it goes. Such projects give good insights into the science, design, and construction of high voltage machines. But I think it needs to go beyond that, unless we want to content ourselves with what seems to be the adult version of kids playing with matches.
Hobbyists and inventors could investigate applications in electroaerodynamics (drag reduction for aircraft which might be useful to the trucking industry). There is also the electrostatic aileron effect (flight control with no moving parts)
Antigravity is one of my favorites. The Biefeld-BrownEffect can certainly be investigated by hobbyists:
( http://scripturalphysics.org/4v4a/ADVPROP.html#Biefeld-BrownEffect ). Others are more difficult.
The Papp engine effect is another interesting one:
There are plenty more!
Let's do more than just make sparks!
