There will be one or more Evacuation/Rescue Capsules, made out of extremely strong and thermally-insulating BFC modules, assembled at the bottom of the Shaft, for emergency rescue situations, for example Earthquakes, Landslides, etc., followed by Ice Movement and Damage, or full Destruction of the Elevetor Shaft.
These Capsules will be used both for Personnel's Evacuation and for Rescue Movement across the Ice Sheet upwards to the surface.
The Standalone Rescue Capsule will be a Sphere, equipped with its own, small, SOH Gas Generator inside, producing unlimited quantities of gas, power and heat, out of molten ice. This gas will be used for melting into hot water, or cutting the ice into blocks, by many Ultrahot, 2m-Long Flames, produced by SOH-Gas Burners , thus opening a vertical way for the Capsule to easily move upwards, by a special technology, to the Ice Sheet's Surface, without any extraneous help.
Capsules will be also equipped with powerful, long-distance Lazer Devices producing directional Lazer Beams for choosing the exact direction for the Capsule's route across the ice, and also for signalizing the people on the surface above, where the Capsule is located.
Capsule's 3D-Movement and precise direction will be effected by several computer-controlled push / support Pistons, which activity will be fully complied with the data given by the Laser Beam device.
Wider (~5cm) holes, smelted in the ice by the lasers, could be also used for dropping communication cables, antennas, etc. narrow-diameter things up and down through them.
