Zusammenfassung:	A capacitive powering system constructed to enable wireless power transfers inside a tube-shaped structure (200) includes a capacitive tube (220) including a pair of receiver electrodes (223, 224) connected to a load (221) through a first inductor (222), wherein the first inductor is coupled to the load to resonate the system; a transmitter device (210) including a pair of transmitter electrodes (213, 214) connected to a power driver(211);and an insulating layer (230) for electrically insulating the capacitive tube from the transmitter device to form a capacitive impedance between the pair of transmitter electrodes and the pair of receiver electrodes, wherein a power signal generated by the power driver is wirelessly transferred from the pair of transmitter electrodes to the pair of receiver electrodes to power the load when a frequency of the power signal substantially matches a series-resonance frequency of the first inductor and the capacitive impedance.
