An electrolytic apparatus for using catalyst-coated hollow microspheres to produce gases, store them, and to make them available for later use. The disclosure further relates to an apparatus comprising a valve with a valve bellows, a sensor for sensing oscillations of the valve bellows and for outputting a sensor signal generated by the oscillations, and a comparator circuit, such as a microprocessor, for comparing at least one sensor signal value with at least one reference value. Such operations, for example, may represent a configurable processor ISA.
