2. (Off-topic, since I covered this in class today, lol) what's the reasoning about using heavier Hydrogen for Fusion? Is it the instability of the nucleus to circumvent the Weak/Electromagnetic forces, or something else entirely?
It has to do with the most efficient fusion pathway, what's referred to as the D-T (Deuterium-Tritium) fuel cycle.
Deuterium-2 + Tritium-3 ---> Helium-4 +n
Where the 2 neutrons in the deuterium and the 3 in the tritium together constitute the 4 in the resultant helium atom plus a free neutron. It is this free neutron that then reacts with lithium in the D-T design to produce power in the
n + Lithium-6 ---> Tritium-3 + Helium-4
pathway.
When encountering Lithium-7, the
n + Lithium-7 ---> Tritium-3 + Helium-4 + n
pathway occurs, which fails to produce energy, but repopulates the reaction with neutrons, thus helping it continue, so a D-T reactor would contain both isotopes of Lithium.
so tl; dr: The number of neutrons is important. You can also less efficiently use Deuterium-2 + Deuterium-2 in the D-D fuel cycle.
I think there was some fusion pathway that uses vanilla hydrogen to combine with a heavier element to reduce neuton production (because energetic neutrons will cook your face) but I forget.
On topic: This looks fucking awesome, please continue this.
Edit: oooh, I just noticed this is a legit D-D reactor. Very cool.
Do D-cells stack? I assume not, it seems like kind of a pain in the ass to refuel and reignite the thing every 300k EU.
But I guess Tritium will fix that yes? Oh but it has fuel storage I see now.
