The galleys inside airliners voraciously consume power - a vital yet limited resource in a plane. Additional power units may soon come to the rescue: housed inside trolley carts in the galleys, these units deliver both supplemental power and thus uncouple the power to the cabin and the kitchen from that which is supplied to the rest of the aircraft. This novel technology is a debut feature on Trade Days at the International Paris Air Show, June 15 to 21 (Hall 1, Booth G316).
