DailyDirt: The Second Most Abundant Element In The Universe…

from the urls-we-dig-up dept

Helium is a fascinating element that most people recognize as the stuff that you can inhale to make your voice sound funny. However, it has some really serious uses in MRI machines and rocket engines — and if we’re not careful, we could waste this precious material and not have any kind of replacement for it. Once we run out of helium on earth, there aren’t a lot of great options for obtaining more. It’s not like we can just swing by Jupiter and bring some back. Maybe we can recycle and conserve for a bit, and perhaps someday we’ll figure out fusion.

Singing

Imagine a large helium leak that spread around the world. Then imagine everyone singing “We’re off to see the wizard, the wonderful wizard of Oz.” That would be amazing… Disclaimer. I am not going to be held responsible for my post if a lawsuit happens. I give that people portion to Techdirt. But if this comment makes the funny list. Or praised in any form without chance of me getting in trouble. Then it is so mine baby….

Re: Re:

Not for rocket engines.

The helium is used to maintain the pressure in the tanks as the fuel drains out. Helium is of course very light, which saves weight. Its lower density stops it from mixing with the fuel. (You REALLY don’t want bubbles in the fuel being fed into your engines.) And being inert it doesn’t react with the fuel.
