Instead of listing a source like I asked two times now you'll ask me for one. Despite me mentioning real life science for the lack of lore. A hack theory... for a bunch of elements that were discovered before the timeline split or in the Manhattan Project. You don't understand what a theory is since you keep mentioning your own as canon. Real life science to you is... that's a hack theory to you? Really? Okay.
You consider the absence of lore as permission to fill in your own scientific headcanons instead of defaulting to how it works in reality. I honestly can't believe it.
Its not like what I said conflicts with Fallout lore. Only Uranium as a source of nuclear power wouldn't work. The supply wouldn't match the need with how much micro-fusion was used.
I really need to stop participating in online debates. Consider this my end point of debating this topic. I need sleep.
"The supply wouldn't match the need with how much micro-fusion was used"
No shit, you've been ranting about real life applications of science while ignoring what the actual lore said,
they WERE running out of Uranium and this is consistent in both Obsidian and Bethesda lore.
Fallout 2 Characters mention THREE times that Uranium was a rare resource, if there were plenty of alternatives Uranium wouldn't be so rare they wouldn't have built vaults to run off of Uranium and Uranium wouldn't be such a focus in the series.
Obviously yes it doesn't make sense that it uses primarily Uranium, but that's what they wrote. It's literally canonically not with in their ability to do so, like use critical thinking for just one sentence and look at the world building from the lore.
If there were alternatives the NCR wouldn't be so desperate the fight for Hoover Dam, they could have built a dozen nuclear reactors between Fallout 2 and New Vegas, yet you're not even accepting Obsidian writing.
TLDR;
1) Creating Nuclear Plants with fusion technology requires Uranium
2) There isn't enough Uranium and other resources to do so
3) They likely don't even have the trained personnel and infrastructure to conduct such a project
4) A macguffin that doesn't need tremendous amounts of resources and time devoted on a massive scale involving thousands of workers is going to much better for NCR immediate recuperation.
Ergo the Plot macguffin is not stupid because you don't understand the NCR isn't the Culture, they have tremendous amounts of resources and get both a significant amount of water and electricity from Hoover Dam.
