Abstract: In a preferred embodiment, an environmentally insensitive electric detonator system for demolition, including: an object to be demolished; a main explosive charge in proximity to the object to be demolished; electrically activated detonator apparatus including a relatively insensitive initiating charge in proximity to the main explosive charge; and circuitry having input apparatus to receive an input firing pulse and having output apparatus to provide, through arbitrarily long wires, a high voltage in response thereto across the electrically activated detonator apparatus to cause ignition of the main explosive charge.
