Full Description

At temple scale, no external power is needed. Human voice at ~90dB per person. 500 voices in unison: 90 + 10*log10(500) = 90 + 27 = 117dB SPL. In a Q=100 resonant limestone chamber, resonant modes are amplified 100x = effective 137+ dB at resonant frequencies. This exceeds the ~120dB threshold for significant piezoelectric EM field generation in limestone. The technology runs on HUMAN BREATH. No electricity, no batteries, no fuel. This is why it lasted millennia. This is why it could be rebuilt anywhere on Earth with nothing but stone, water, and singing voices.
