Rules (2024-08-30)

  1. This is an English-language community. Comments should be in English. Posts can link to non-English news sources when providing a full-text translation in the post description. Automated translations are fine, as long as they don't overly distort the content.
  2. No links to misinformation or commercial advertising. When you post outdated/historic articles, add the year of publication to the post title. Infographics must include a source and a year of creation; if possible, also provide a link to the source.
  3. Be kind to each other, and argue in good faith. Don't post direct insults nor disrespectful and condescending comments. Don't troll nor incite hatred. Don't look for novel argumentation strategies at Wikipedia's List of fallacies.
  4. No bigotry, sexism, racism, antisemitism, islamophobia, dehumanization of minorities, or glorification of National Socialism. We follow German law; don't question the statehood of Israel.
  5. Be the signal, not the noise: Strive to post insightful comments. Add "/s" when you're being sarcastic (and don't use it to break rule no. 3).
  6. If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
  7. Light-hearted content, memes, and posts about your European everyday belong in other communities.
  8. Don't evade bans. If we notice ban evasion, that will result in a permanent ban for all the accounts we can associate with you.
  9. No posts linking to speculative reporting about ongoing events with unclear backgrounds. Please wait at least 12 hours. (E.g., do not post breathless reporting on an ongoing terror attack.)
  10. Always provide context with posts: Don't post uncontextualized images or videos, and don't start discussions without giving some context first.

(This list may get expanded as necessary.)

Posts that link to the following sources will be removed

Unless they're the only sources, please also avoid The Sun, Daily Mail, any "thinktank" type organization, and non-Lemmy social media. Don't link to Twitter directly, instead use xcancel.com. For Reddit, use old:reddit:com

(Lists may get expanded as necessary.)

Ban lengths, etc.

We will use some leeway to decide whether to remove a comment.

If need be, there are also bans: 3 days for lighter offenses, 7 or 14 days for bigger offenses, and permanent bans for people who don't show any willingness to participate productively. If we think the ban reason is obvious, we may not specifically write to you.

If you want to protest a removal or ban, feel free to write privately to the primary mod account @[email protected]

Iceland Could Become First Nation To Get Solar Power From Space In 2030 (www.iflscience.com)

UK-based company Space Solar is partnering with Reykjavik Energy and Icelandic sustainability initiative Transition Labs to develop a space-based solar power plant that can deliver about 30 megawatts of electricity – potentially enough to power between 1,500 and 3,000 homes – from 2030. The system will collect sunlight in space through solar panels and then transmit it as radio waves at a specific frequency to a ground station, where it will be converted to electricity for the grid.

The satellite is expected to be scalable and quite big. Even if a full version of their CASSIOPeiA power array is not built, we are talking about the heaviest single object in space that is not a space station, and when all the arrays are splayed out, much larger than the International Space Station.

The company aims to have a scaled-up version of the system in space by 2036, which would supply gigawatts of electricity.

Given their abundance of geothermal energy (they keep their footpaths ice-free year round and still have enough to power energy-hungry facilities such as aluminium smelters and data centres), Iceland is probably the country that least needs this.

Most of Iceland's energy usage is from geothermal sources, but only about a quarter of the electricity is. They do a lot of direct heating with it, literally just heating up a whole bunch of water and running that hot water through pipes to houses and pavements and such, rather than having electricity-powered heating elements everywhere. Most of their electricity production is from hydro though, so it's still very clean

We don’t need to heat the water, it’s already hot when it comes from the ground 😀

Well there are places where the cold water is heated up using the hot water before it goes to peoples houses because the original hot water smells and tastes bad…

And where the pavements and walkways are heated it’s the exess water flowing away after being used to heat the houses not the other way around
