What sort of wavelength are you talking about for Far C? Read: how different is this than 1nm 'soft' x-rays?

Reply to comment by PlaidBastard in Is the percentage of mass in the parent star, comparable between different systems? by bizzehdee
There's one big caveat to add on to this as well: a lot of current conjecture is that more stars are in multi-star systems than not. //Don't have a reputable source for this, am armchair at best with any of this.
I don't know how widely accepted it is that more stars are in binaries+ than not; regardless, in those systems you'd have a large variation in planetary creation and a non-trivial percentage mass in the partner star.

From the equation you've posted you're reacting magnetite with hydrogen gas directly, and generating water vapor and iron as your end products. It's been ages since I calculated enthalpy, but quick searches say you'll need to put in 150kJ of energy per mole reacted.
Said differently, in boring conditions, wet iron rusts, sometimes into magnetite and if it does so, it will evolve off hydrogen gas.

Reply to comment by redruben234 in Why not use hydrogen and deuterium in fusion reaction rather than tritium and deuterium? by Curious_user4445
It's valuable largely because it's not the easiest thing to purify, as far as I understand it. As far as elements go, it's not uncommon in minerals, and it's not ultra rare in seawater, for easy reading: https://en.wikipedia.org/wiki/Lithium#Terrestrial

That's awesome! Thank you
