From the data obtained in his capacitor charge experiment, Buehler's calculation
gave a value of 0.47 newton "AG" force per Joule "stored" in the capacitor whether
the dielectric was air or bee's wax.
This squares with the 20 joules per kilogram force that is required for
1.0 kilogram weightlessness, plus the 1/2 mv^2 joule, kinetic energy requirement.
The metallized film capacitors offer a convenient way of either storing
or cycling (rapid charge-discharge) of the stored energy
Metallized Kapton (2.0 mil polyimide film) with K ~ 3.4, at about 6.0e-6 farad
per square meter could "store" 20 joules per square meter at about 8,000 volts
OTOH, pulsing/(rapid cycling) with matched resistive load could
substantially lower the voltage requirement.
