Is not counting rain, equivalent to only counting the energy released by the laswers, not the energy fed into the lasers? [[User:Arachrah|Arachrah]] ([[User talk:Arachrah|talk]]) 20:47, 13 December 2022 (UTC)

ChatGPT sez:

The comic depicts Beret Guy, a character known for his expertise in science and engineering, standing on a podium and announcing that their hydroelectric dam has achieved a level of efficiency greater than one, producing more water than was fed into it. This is cause for celebration, as it indicates that the dam is functioning properly and efficiently. However, the second off-panel voice raises a question, suggesting that there may be more to the situation than initially thought.
The title text adds further information by revealing that a hydroelectric dam is also known as a heavy water reactor. This suggests that the dam may not be operating in the traditional way, but rather may be using a different type of technology, such as nuclear power, to produce the excess water. This could raise concerns about safety and the potential risks associated with this type of technology.

It *is* possible. All Beret Guy has to do is use the electricity to run air conditioners, which will have one side condensing water from the atmosphere, ergo more water coming out than went in. SDSpivey (talk) 04:00, 13 December 2022 (UTC)

I think there's a conservation of energy violation here, but can't model the entire system. 172.70.134.97 14:31, 13 December 2022 (UTC)

Considering that he phrases it "more water than we fed into it" in the past tense, it might just be that there's a leak in the dam. 172.69.33.19 04:06, 13 December 2022 (UTC) mraction

More variation: "more water than *we* fed into it" ie not counting water from the river that feeds it, or rainfall. There's also the title text turn of phrase "heavy water reactor". "heavy" could refer to either the "water" (in the sense of gravity, or deuterium passing through), or the "reactor" (as in its mass) - 172.70.210.242 05:43, 13 December 2022 (UTC)

If Q is only barely >1 it could square the circle by converting atoms to oxygen by fusion in order to create water but the whole energy of the dam is used to make the fusion of a few oxygen atoms.

"Another member of audience, who is presumably familiar with regular physics, says "Wait.", because conservation of mass usually applies to water such that a dam should produce the same amount of water as that fed into it. That said, for a regular dam in a natural valley like the one shown in this comic, it is entirely normal for the dam to "produce" more water than input in the sense that in addition to water from upstream rivers, the dam will also output any "unofficial" inflow from direct rainfall above and from uncharted sources of groundwater below."
I thought that the "Wait" comment was in relation to the fact that the announcement, although achieving something that was not achieved so far, is impractical. As the power plants are expected to produce energy, announcement that they produce additional water is irrelevant, and the "wait" comment indicated that they have missed the point. 172.68.50.204 (talk) (please sign your comments with ~~~~)

Given the title of Hydropower Breakthrough, is a possible interpretation that the dam is just about to fail? --172.68.110.171 10:35, 13 December 2022 (UTC)

My immediate thought was that he was using the generated electricity to ignite a hydrogen cell, but my immediate thoughts are always weird. 172.70.134.97 14:31, 13 December 2022 (UTC)

I feel Randall's comic is strongly indicative of a fair degree of skepticism around recent fusion power hype (many existing fission reactors produce an energy surplus, but fail to meet their cost of operations)... Yet, the comic's explanation currently reads as a guileless exhortation of fusion's possibilities, making no mention of the many other challenges faced by fusion reactors, besides this critical first step of generating more power than required to sustain the reaction. The comic is clearly making light of the recent publication\marketing push, yet the explanation gives no sign that fusion power is anything but practical & just around the corner. Fusion still has many remaining challenges to overcome, before reaching practicality as an energy source even for military applications (moreso still, for public utility); wind & solar are the top KWh:$ producers & another 10 or 100 billion spent researching fusion are very unlikely to change that in the next couple decades. In fact, solar research returns more Watts per dollar. The comic should probably mention the other challenges involved in nuclear fusion power, besides raw output quantity?

I think the explanation is overthinking it. The joke is that there's a leak in the dam. An idiot (talk) 16:37, 13 December 2022 (UTC)

The explanation says nothing about the effect this would have downriver from the dam. Inquirer (talk) 16:51, 13 December 2022 (UTC)
