Last night I was thinking and I got an idea about using multiple types 
dielectrics in a capacitor. ( I'd like to take this moment to say, I'm an 
amateur, I have no idea if any of this would work. Just thought it was 
worth asking about.)
What if you took 2 layers of something with a very high breakdown voltage 
(maybe some type of spray on/ paint on high voltage insulation) and placed 
a layer something with a high dielectric constant between the 2 high 
voltage layers?  Could this result in a very small amount of space between 
the plates of the capacitor, and a high dielectric constant, there for a 
high capacitance and high break down voltage?
