1925年氦气法案

1925年氦气法案（50 USC § 161）是美国为保护、勘探和采购氦气而起草的一项法案。该法案授权征用、租赁或购买具有生产氦气潜力的土地。该法令同时禁止出口氦气，但美国在当时是几乎唯一的氦气来源，这迫使外国飞艇使用氢气而非氦气以提供升力。 该法案授权美国内政部和美国矿业局对升力气体（英语：Lifting gas）升力气体的实验、生产、提纯和研究进行管辖。该法案的通过为建立联邦氦气储备库（英语：National Helium Reserve）提供了权力。 第104屆美國國會提出四項法案，旨在將美國聯邦氦氣生產和精煉工作私有化。1996年10月9日，柯林頓政府（英语：Presidency of Bill Clinton）正式通過《1996年氦氣私有化法案（英语：Helium Privatization Act of 1996）》，廢除美國聯邦氦氣提煉計劃。 飞艇 升力气体（英语：Lifting gas） 兴登堡号空难 There is a World-Wide Shortage of Helium. interestingengineering.com. 2019-06-09 [2020-08-16] （美国英语）.  H.R. 846 ~ Helium Act of 1995.
