Claim:
1. An energy storage structure, comprising: a structure selected from a nanocomposite structure including nano-CaCO 3 lamina dispersed in a biopolymer matrix with crystalline orientations, where the nanocomposite structure is obtained from a conch shell having predetermined dimensions and the structure has one or more characteristics selected from the following: a remanent electrical polarization of about 2 to 4 kμCcm −2 , a relative dielectric constant of about 80 to 300 at a frequency of about 100 Hz and a relative dielectric constant of about 13 to 19 at about 1 MHz; and a remanent polarization of about 3000 to 3200 μCcm −2 at 3.1 mHz and a remanent polarization of about 2050 to 2250 μCcm −2 at 0.01 Hz.
