Later, the USA began to use helium because it is non-flammable and has 92.7 % of the buoyancy ( lifting power ) of hydrogen.
12.
Lifting power was supplied by two overshot waterwheels in diameter, one on each side of the inclined plane, connected to the cart with chains.

Financed by his shows, Cody significantly developed Lawrence Hargrave's double-cell box kite to increase its lifting power, especially by adding wings on either side.
14.
Tuner Steinmetz developed a special version of the Ascona SR, with two single-barrel Solex carburettors, lifting power to 125 PS ( 92 kW ).
15.
This makes it lighter and, if its lifting power is greater than the weight of the balloon containing it, it will lift the balloon upwards.
16.
This enables the balloon to maintain altitude at night, when cold air and the lack of sunlight cools the helium and lessens its lifting power.
17.
:An airship in a vacuum wouldn't explode ( unless it was already close to exploding in air ), but it wouldn't provide any lifting power.
18.
The lifting power and reliability of Titan missiles led to its selection and use in the NASA Gemini program of manned space capsules in the mid-1960s.
19.
This made it virtually impossible to pass cables under the hull and required far more lifting power than if the ship had settled on a hard seabed.
20.
If helium is used instead of vacuum, the lifting power of every liter is reduced by 0.178 g, so the effective lift is reduced by 14 %.
