In court filings, project leaders said Pure Helium planned to spend $300,000 constructing the well pad and improving the access road. Drilling the first well would take 20 days and cost $1.3 million.

In helium purification, the 90% pure gas is pumped into a pressure vessel containing a molecular sieve, usually Zeolite. The contaminating gasses are preferentially adsorbed into the Zeolite ...

Inhaling helium might seem like a harmless way to get a few laughs, but it might be more hazardous than you think. ... Breathing in pure helium can cause death by asphyxiation in just minutes.

Pure helium stars don't exist in the universe, but we can get a good idea of what they might by like by looking at red giant stars. These are old stars that have used up most of their hydrogen.

So white dwarf atmospheres are typically composed of pure hydrogen or pure helium. That's why this latest discovery of a white dwarf is so intriguing. Astronomer Ilaria Caiazzo, ...

In the first quarter of 2022, we expect to demonstrate Imperial Helium’s ability to produce 99.999% pure Helium from the Prototype Plant, utilizing a gas sample from the Steveville asset.

They call it primary helium. Other people might call it pure-play helium. But they’re going after helium just for helium’s sake. I think that’s going to be an interesting thing to watch.

The researchers displaced the air in six bottles and replaced it with pure hydrogen gas, pure helium gas or a mixture of 80 percent nitrogen and 20 percent carbon dioxide. A final set of bottles ...

The first stars in the universe are theorized to be made of pure helium, hydrogen, and some lithium before seeding other metals through supernova explosions. Credit: NAOJ illustration If you've ...
