A device for harvesting and storing triboelectric charge generated on an exterior surface of a moving vehicle is provided. It is characterised by comprising a supercapacitor comprised of nano-carbon-containing electrodes; an ionic liquid electrolyte and at least one ion-permeable porous membrane; at least one first element exposed to aerodynamically-induced frictional forces acting thereon and onwhich the charge is caused to build up and connected to at least one of the electrodes of one polarity; at least one second element having a lower electrostatic potential than the charge collecting element and connected toat least one of the electrodes of the other polarity; a voltage modification or impedance conversion circuit arranged between the first and/or second elements and the supercapacitor; a means for connecting the device to an operative component requiring electrical power and a controller for managing the performance of the device and switching between energy harvesting and energy utilisation modes. The device is especially use for deployment in the wing of an aircraft to utilised triboelectric charge generated thereon.
