  "textContent": "A power system includes a liquid hydrogen fuel source including a fuel tank (14) containing a volume of hydrogen fuel (12). The fuel tank includes two or more vacuum insulation layers (52), and a liquid insulation material (54) positioned between the two or more vacuum insulation layers. A first power generator (22a) located fluidly downstream of the hydrogen fuel source. The first power generator utilizes a flow of hydrogen fuel from the volume of hydrogen fuel to generate electrical or mechanical power.",
