A lighter than air vehicle or aerostat comprising a first envelope 34, a second envelope 36 inside the first envelope, and a tube 40 connecting the first envelope to the second envelope. The first envelope and the second envelope are spaced apart so as to define a chamber, filled with a buoyant lighter than air gas, between two envelopes. A first opening of the tube 40 is located at an external surface of the first envelope, and at the other end of the tube, a second opening is located on the interior surface of the second envelope. Preferably, some kind of device such as a mirror, or solar power generator is located within the second envelope. In some embodiments the outer envelope is lined by a mirror, the shape of which can be changed to focus light onto a power generating device.
