 Voltage independence of permittivity was claimed up to 500 V/μm to within 0.25% of low voltage measurements.Variation in permittivity at a single voltage for 10 different components was claimed by measurements in the patent to be less than +/- 0.15%.If true, their capacitors store at least 30 times more energy per volume than (other) cutting-edge methods such as nanotube designs by Dr Schindall at M.I.T., Dr. Ducharme's plastics research, and breakthrough ceramics discussed by Dr. Cann.
