I detailed the answer with the information he needs, with source links,
The issue here is that you really didn't "detail the answer". You did give a list of power supply types and their relevant wattages, but you failed to address how a society "at a level of technology that includes wooden and stone tools but not metal ones" would make use of a large wind turbine or a nuclear microreactor.
As examples of how much power output you get, the list is fine, but it falls to the respondent to weave that into a helpful answer.
Yeah, you did. In reading through your response, I can't imagine why. Honestly, I'm not digging at you: answers that involved the Bhagdad battery and bamboo bicycle generators also got upvoted, when they really fail to address the same basic premise you failed to address.
and the answer was deleted with the explanation that it "does not provide an answer".
It's possible that you did not see JBH's explanation. I neither agree nor disagree with it, but provide it here on the off chance you can't see it: "What's particularly frustrating with this non-answer is that (a) you've repeated information the OP has already stated, (b) you admit that the answer depends on information not presented by the OP, (c) you don't actually present a solution to the problem. Worse, you don't know what kind of weapon is being used, what its energy requirements are, or just how primitive the primitives are. And yet you posted a response (I can't call it an answer) anyway. Strange as it may seem, the goal of Stack Exchange really isn't to answer anything and everything that comes along."
In what way does detailing energy sources not answer a question asking about how to get energy?
Largely because the OP did not ask about energy sources per se. The OP could easily have dispensed with the question entirely by providing the locals with an appropriate charging device.
The OP is, in fact, asking a question about people that she characterises as "primitive" and having only tools made from wood and stone (and presumably bone and horn and antler) but not metals.
Ultimately, stone-age people cannot provide their own energy therefore the question is about what the advanced civilization needs to include in order to make it feasible.
I agree with your finding of fact here. This doesn't answer the question, however, and I'm frankly surprised that you think it does. This is a comment, and should have been addressed directly to the OP as such.
The answer cannot write the story for the author, so JBH's comments on my post were inappropriate and incorrect. We are not here to write the story for the author. We need to explain the mechanics involved and help the author develop his own story.
This is actually incorrect as well. We're not here to help the author develop his own story at all. Far from it. We're here to help the author build or develop the world their story is set in. Which of course, is where I think you were headed with your response.
You just didn't have enough solar panels to get you there! My conclusion is thus that your response was deleted because it doesn't address the problem as stated by the querent.
Now, I would argue that if you had written So as I see it the advanced society must provide a charging solution and then proceeded to provide some kind of charging solution that would solve the problem, we wouldn't be in this situation. You could have said something like "a disposable charger unit with enough capacity to recharge the weapon x number of times; much like a gas canister weapon, it be sufficient for two or three hunting expeditions, but would then need to be traded for a new unit." Problem solved!
(Edit: The question has since attracted new answers, which are basically flavors of my deleted answer. The moderators are now on the hook to delete those answers as well, or else undelete mine. While I may not agree with this deletion, I don't think "consistent enforcement of the rules" is too much to ask for in any case, and, to that end, "be careful what rules you establish, because once established, you will be on the hook to continue enforcing them.")
Well, not exactly flavours of your answer --- because you didn't even provide two bits of metal in a lemon! Your answer was literally to push it back onto the querent by saying So as I see it the advanced society must provide a charging solution.
