No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)

Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.

Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.

Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.

Rule 4- No self promotion or upvote-farming of any kind.

That's it.

Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.

Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.

Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

Rule 8- All comments should try to stay relevant to their parent content.

Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.

Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

On one hand many countries will invest in heavy industry, manufacturing, and fall back to fossil fuels.

On the other hand, economy overall should slow down and consumption of non-essential goods and services will drop.

I'm not expecting any definite answers or numbers, of course, just some food for thought.

Iran tried farm-to-table nukes, but they weren't very popular.

The next US tanks is supposed to be a disele electric hybrid actually. But I'm not saying this because I think it'll be some sort of improvement. It's just interesting that they think that is the superior tech.

It has been tried many times in history since the first tanks. I wonder if modern battery tech makes it more feasible than it was 100 years ago.

This is indeed not a new concept. Almost all locomotives are diesel electric. Some also have batteries making them hybrids. But the previous tank (Ambrams) was using an absolute gas guzzling turbo-shaft. So this is a pretty radical departure.

As for battery technology... Let's compare LiFePo4 (not the densest, but safe, reliable, long lasting with wide operating ranges) to modern lead acid (let alone 100 year old lead acid)...

Energy Density (Weight): 120-200 Wh/kg vs 30-50 Wh/kg
Energy Density (Volume): 250-530 Wh/L vs 75-120 Wh/L
Cycle Life: 1000-3000 cycles vs 200-1000 cycles

About the only thing they've really embraced is electric motorcycles as they're quiet.

There are hybrids, even in WWI there were French tanks with hybrid drivetrains, then WWII Germans also had super-heavy stuff with hybrid engines, and the AbramsX is supposed to also be like that.
