Map showing helium-rich gas fields and helium processing plants in the United States, 2012. From USGS. Helium production in the United States totaled 73 million cubic meters in 2014. The US was the world's largest helium producer, providing 40 percent of world supply. In addition, the US federal government sold 30 million cubic meters from storage.
In mid-1982, Walters and his then girlfriend, Carol Van Deusen, purchased 45 eight-foot (2.4 m) weather balloons from a military surplus store [5] and helium tanks from California Toy Time Balloons. They used a forged requisition from his employer, FilmFair Studios, saying the balloons were for a
The Crude Helium Enrichment Unit in the Cliffside Gas Field. Remnants of the Amarillo Helium Plant in 2015. The National Helium Reserve, also known as the Federal Helium Reserve, is a strategic reserve of the United States, which once held over 1 billion cubic meters (about 170,000,000 kg) [a] of helium gas.
A balloon can only have buoyancy if there is a medium that has a higher average density than the balloon itself. Balloons cannot work on the Moon because it has almost no atmosphere. [15] Mars has a very thin atmosphere – the pressure is only 1 ⁄ 160 of earth atmospheric pressure – so a huge balloon would be needed even for a tiny lifting ...
Helium is the most common element in the universe after hydrogen, with a mass fraction of about 24%. Most of the helium in the universe was formed during Big Bang nucleosynthesis, but the amount of helium is steadily increasing due to the fusion of hydrogen in stellar nucleosynthesis (and, to a very slight degree, the alpha decay of heavy ...
An airborne engine drives the generator, supplied by a 100-gallon diesel fuel tank. Beginning in the late 1990s, the aerostat sites were equipped with Lockheed Martin 420K aerostats. This version carries the Lockheed Martin L-88, a surveillance radar with a range of 370 km (200 nm), as its primary payload.
This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
