"cantilevered yttria-stabilized zirconia ceramic minimizes heat conduction/ prevents structural failure, using multilayer insulation trapping heat internally allowing safe touch while reaching operating temperatures in 5 minutes (was 30)... if insulation punctured, temperature drops rapidly below the hydrogen ignition point within 5 minutes... up to 4X gravimetric energy density benefit high-drain edge devices: drones, compact robotics, AI hardware, scalable high-density off-grid power"
