Electricity is generated by redundant systems, including a generator connected to a fuel reserve. DBX shelter also has energy support through geothermal and biomass accumulators. The generator charges 30 lithium batteries and provides electricity from 12 to 120 volts throughout the bunker. The heating and cooling air system are solved by geothermal energy. The water is extracted from the subsoil and passes through a filtration system and ultraviolet light that kills bacteria. The water intended for consumption is stored frozen.
