Florescent light bulb
The following demonstrated the large energy field. The florescent light bulb in these pictures has no wires attached. It is being lit by the E field between the two capacitor plates.
No power on the plates
The capacitor plates are spaced 24 inches apart and the florescent bulb is 18 inches long. The lamp is lit by the capacitive current flowing between the plates. The plates are 24 inches wide and 36 inches high. The lamp lights up the same brilliance anywhere in the space between the plates indicating a uniform field strength.
