* Answer: Helium-3 is lighter. The number refers to the number of protons and neutrons.[[User:Johnm307|Johnm307]] ([[User talk:Johnm307|talk]]) 03:03, 6 January 2021 (UTC)

Contradiction

From the 'Manufacturing' section:

"Commercial use of fusion reactors would require tens of tons of helium-3 each year to produce a fraction of the world's power."

From the 'Lunar supplies' section:

"Accordingly, helium-3 seems less likely than other reactants for use in fusion power generation"

I've amended the sentence from the manufacturing section to make it clear that helium-3 is only one of several possible fusion fuels by changing it to:

"If commercial fusion reactors were to use helium-3 as a fuel, they would require tens of tons of it each year to produce a fraction of the world's power."

I'm pretty sure this is the correct resolution of this contradiction.


Disgusting, unsightly typo

I had to remove an apostrophe from "it's" to turn it into the correct "its".

How come this has been ignored for so long? Are you all illiterate?

Which is lighter

Stable nuclei with more protons than neutrons

"Other than protium (ordinary hydrogen), helium-3 is the only stable isotope of any element with more protons than neutrons. Helium-3 was discovered in 1939." The bare beryllium-7 nucleus is also stable. Be-7 can only decay through electron capture, so the nucleus is unstable when electrons are bound to it. (See the articles on beryllium.)
