It is used in weather balloons and inwelding gases. Liquid helium is used as a closed systemcooling agent. 3.5 Purification Methods Dry the gas by passing it through a column of Linde 5A molecular sieves and CaSO4, then through an activated-charcoal trap cooled in liquid N2, to adsorb N2,...
However, in large volumes, the 1-gram-per-liter difference between air and helium can really add up. This explains why blimps and balloons are generally quite large — they have to displace a lot of air to float. The following diagram shows the different lifting capacities of different ...
Superconductors can only work if they are surrounded by the extreme cold of helium, and helium has been used in the space industry for cooling of satellite instruments and fuel coolant for spacecraft. Meteorologists use helium-filled weather balloons for weather observations. Scanning electron ...
3He is present in very small quantities. Six other isotopes of helium are now recognized. Uses Helium has many uses. As an inert gas, it is used as the atmosphere in which to “grow” silicon crystals (computerchips). As a lifting gas, it is used to inflate weather balloons and ...

Helikite aerostats overcome the shortfalls of normal tethered balloons, UAVs, blimps, aerostats and kites. Helikite aerostats use less helium per kilogram of list than other aerostats. Helikites are more stable, lift heavier payloads and cost much less to purchase and operate than other aero...
(such as growing crystals to make silicon wafers), account for half of its use. Economically minor uses, such as lifting gas in balloons and airships are popularly known.[2] Inhaling a small volume of the gas temporarily changes the timbre and quality of the human voice. In scientific ...
