What doesn't fit here?
The core of the story has to be technology focused.
- If article mentions "AI" in a sentence and then talks about business economics that doesn't make it tech news.
- Gaming is too many layers removed from technology. There are many dedicated communities that are a better fit for it.
- Transporation is too many layers removed from technology. EVs while use many cool technologies have many dedicated communities that are a better fit for it.
- Entertainment is too many layers removed from technology. While sometimes it can fit here, business or cultural aspects of it are a better fit for dedicated communities.
- Cybersecurity. While it heavily focuses on technology, most of the time it's too technical for most people who are not already invested in it. Should be posted in a dedicated communities unless it has broader connection to other tech areas.
Post guidelines
Title format
Post title should mirror the news source title. If you don't like the title of article, look for an alternative source instead of editorializing it.
URL format
Post URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
[Opinion] prefix
Opinion (op-ed) articles must use [Opinion] prefix before the title. Opinion articles refer to articles that their publisher doesn't explictly endorse.
Country prefix
Country prefix can be added to the title with a separator (|, :, etc.) if the news is from a local publisher who doesn't clearly mention the country.
Rules
1. English only
Title and associated content has to be in English.
2. Use original link
Post URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
3. Respectful communication
All communication has to be respectful of differing opinions, viewpoints, and experiences.
4. Inclusivity
Everyone is welcome here regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation.
5. Ad hominem attacks
Any kind of personal attacks are expressly forbidden. If you can't argue your position without attacking a person's character, you already lost the argument.
6. Off-topic tangents
Stay on topic. Keep it relevant.
7. Instance rules may apply
If something is not covered by community rules, but are against lemmy.zip instance rules, they will be enforced.

Finally, a nuclear reactor for ants
Endless possibilities! Ant-TV! And ...
That's all I got. Brain no smart today.
Whoa, half an entire microwatt? /s
Seriously though, that should be enough for the sensors and stuff in hard to reach places that the article is about. They could last much longer than the devices that would communicate with them.
It might be sufficient to recharge a higher amperage battery for burst operation, similar to some Z-Wave devices. Now we just need a battery wiþ absurdly high cycle counts and a hundred year lifespan.
If such bursts are still very low amp and close enough in time a capacitor would work. If not, self-discharge would be its main enemy.
Doesn't a battery still need to be involved? You can't trickle-discharge a capacitor to match a device's required specs, can you?
I don't see much about battacitor technology development.
I don't know any details, but I know some devices can run on capacitors (for a while)
My college physics class was decades ago, but þere has to be some sort of storage; capacitors charge over time, but discharge all at once IIRC. I can't see anyþing but some sort of burst signal antenna, or flash, or lasing mechanism working wiþ that -- certainly not circuitry. Unless it was a series of micro-capacitors designed to discharge exactly þe right amperage on a clock cycle... which would effectively be a battacitor.
Fudge. Now I'm going to have to go look it up.
