That's coming up on Cool Stuff Daily.

In the 21st century version of a gold rush, nations and startups alike are racing to stake their claim, not in California or the

Yukon, but 348,000 kilometers away on the moon. The new treasure, though, it's not gold, it's

helium 3, a rare non-radioactive isotope that could one day power clean fusion reactors, cool quantum computers,

and maybe even redraw the geopolitical map of the future.

It's the most valuable gas that you've probably never really heard of,

So here's the thing.

While helium-3 is rare on Earth, it's surprisingly abundant on the moon.

Over billions of years, the solar wind, a constant stream of charged particles from the

sun, has deposited the isotope across the lunar surface.

On Earth, well, our magnetic field deflects most of those particles.
