Rules (2024-08-30)
- 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.
- 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 When you post outdated/historic articles, add the year of publication to the post title.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.
- 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.
- 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.
- 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).
- If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
- Light-hearted content, memes, and posts about your European everyday belong in other communities.
- 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.
- 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.)
- 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
- on any topic: Al Mayadeen, brusselssignal:eu, citjourno:com, europesays:com, Breitbart, Daily Caller, Fox, GB News, geo-trends:eu, news-pravda:com, OAN, RT, sociable:co, any AI slop sites (when in doubt please look for a credible imprint/about page), change:org (for privacy reasons)
- on Middle-East topics: Al Jazeera
- on Hungary: Euronews
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 @EuroMod@feddit.org

I thought a shot of this kind of stuff would be way more expensive in terms of power supply
Well, according to https://www.ex2.com.au/news/eos-unveils-apollo-high-energy-laser-weapon-helw/
it'd be quite affordable, even if that power had to be sustained continuously.
1 hour of operation requires 150 kWh of energy. That's a steal compared to alternative "ammo".
It's even more of a steal since it can be easily recharged using a trivially available and easily transported resource you'll need anyway in order to be mobile: Fuel.
Yeah me too. And it was said also that the energy levels needed for a beam to penatrate was very high, especially for long distances.
+Here some more info on the EOS' ‘Apollo’ High Energy Laser Weapon (HELW), 100~150 kwh. Nothing like starwars ofc, still issues with humidity, fog and hills fyi.
Still could be a neat thing if it works well in the field. I wonder how it will do during (North) European (winter) conditions.
I pay $0.10575/kwh - now this varies around the world, but let us round it to $.10 which is reasonable and makes math easy. $1 then would be 10 kwh over 1 minute - that is a lot of power. Of course they are probably using a generator so $.50/kwh is more likely, but still we are getting 2kwh over 1 minute - that is a lot of power and a big generator.
Yes, indeed it's a heavy energy using Laser the Aussies made.
US energy prices are very low, like 60% cheaper compared to European prices which are around€ 0,22 per kWh ( 2024)
A generator capable of powering that kind of equipment will definitely come with a price tag of some description, but in the not even very long run it'll be cheaper, because it is a mass produced widely available piece of industrial equipment, and uses a relatively inexpensive consumable. The expensive bit here is the laser itself, powering it is dirt cheap in comparison. The laser will draw up to 150kW of power, a diesel generator in that power range will burn roundabout 40l of diesel an hour under full load. That's way cheaper (and more compact) than even a relatively small amount of ammunition you could use for shooting at drones instead of frying them with an enormous laser, and a dude carrying jerrycans working at a leisurely pace could easily keep it resupplied.
