A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted, clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts: 1

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
    • If you feel strongly that you want politics back, please volunteer as a mod.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report the message goes away and you never worry about it.

Fossil fuel would I guess be chemically stored fusion energy from a long time ago

I could be wrong, but I think geothermal may be the exception to that. That heat is from the formation of the planet and radioactive decay.

Radioactive elements were formed in the last moments of a collapsing star, so even those were formed during fusion.

[–] ptz@dubvee.org 3 points 2 years ago

That is true. I guess it depends on how much of the heat is generated via fission processes and how much is just stored from planetary accretion. I don't have any numbers for that at this moment, but I will certainly concede that geothermal is fusion-assisted lol.

Maybe tidal energy would also be an exception? It's from the motion of the moon, which is the result of ancient planetary collisions?

Ooh, yeah. Didn't even think of tidal energy. I don't think we get any significant amounts from it currently, but it's being actively developed.

I guess if we want to get super pedantic about it, it would also be fusion-assisted since without the sun's energy keeping the oceans in a liquid state, it would be frozen and unable to generate any power.

How does wind energy fit then?

Or hydro electric dams?

[–] ptz@dubvee.org 6 points 2 years ago

Wind: The sun (a giant fusion reactor) heats the atmosphere which generates the wind (highly simplified).

Hydro: Driven by the water cycle where the sun plays a key role in the "evaporation, condensation, precipitation" process.

[–] JohnDClay@sh.itjust.works 4 points 2 years ago

Wind is due to the asemetric effects of heating different parts of the globe different amounts. Hydro is from rain and snow which is evaporated with the sun

I guess, if you're taking into account the formation of all matter with the beginning of the universe.
