What is Helium-3? Thanks for asking!

Helium-3 is a helium isotope which contains two protons and a neutron. It dates back to the earliest days of the universe and formed in the mantle of planet Earth. However, humans only discovered it in 1934.

It is a pretty unique gas, with rare and valuable properties. For example, it can reduce temperatures to nearly absolute zero, which could be useful in cryogenics or medical imaging. Most of all, it’s known for producing enormous quantities of energy. Estimates vary, but it’s been suggested that just a few hundred tons of Helium-3 would be enough to meet the entire planet’s energy needs for a whole year.

Great, could Helium-3 be a potential energy source of the future then? Could we really bring back Helium-3 from the moon? Is anyone trying to mine Helium-3 right now? In under 3 minutes, we answer your questions!
