A neutrally buoyant airship, such as a blimp, contains a lifting body which allows
the airship to remain neutrally buoyant in air and a fuel cell located in the airship.
A method of generating power in the neutrally buoyant airship, comprising providing
a fuel and a oxidizer to a solid oxide fuel cell to generate power, and providing
heat from the fuel cell to a remotely located lifting body, wherein the lifting
body allows the airship to remain neutrally buoyant in air.
