Static electricity, which may be after such lightning discharge some time stored underground at random natural capacitor isolated by high efficiency dielectric (some stones) may represent many kilowatt-hours (megajoules).
Tuli umeme, ambayo inaweza kuwa kavu baada ya kutokwa umeme baadhi ya wakati katika capacitor random Kuhifadhiwa chini ya ardhi ya asili kutengwa na dielectric high ufanisi (baadhi mawe) inaweza Kuwakilisha wengi kilowatt masaa-(megajoules).
