electric motor or internal
combustion as well.
• The unguarded belts and
machines led to horrific injuries.
• Children were employed as they
could get into small places that
adults couldn’t reach.

General characteristics
Crew: One pilot
Length: 44.00 m (144 ft 4 in)
Volume: 300 m3 (10,600 ft3)
Powerplant: 1 × steam engine, 2 kW (3 hp)
Performance
Maximum speed: 9 km/h (6 mph)
41. 1000 Cubic Feet at 60° F, Barometric Pressure 29.92″ Hg
Weight of Lifting Gas Weight of Air Net Lift
Hydrogen 5.31 lbs 76.36 lbs 71.05 lbs
Helium 10.54 lbs 76.36 lbs 65.82 lbs
Assume 10,000 tons or 20,000,000 pounds you need to have 281,491,907.11 CuFt.
That is 3127.68 Ft. long and 300 Ft. wide and 300 Ft. high just for the gas.
