Technology
Vacuum Airship Core. Zero Helium. Pure Lift. Perpetual Solar Power.
Revolutionary vacuum buoyancy technology replaces scarce helium with evacuated UltraVacuum Composite chambers providing 1.29 kg per cubic meter of lift at 10 km altitude. Ninety percent lighter than conventional airships, ninety-four percent cheaper to operate, with over fifty years of maintenance-free service life. Paired with four gigawatt-hours of annual solar energy harvested above the clouds.
