What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

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

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



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

Your post 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.

Posts and comments 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 non-TIL posts.

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



Rule 7- You can't harass or disturb other members.

If you vocally 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.

For further explanation, clarification and feedback about this rule, you may follow this link.



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.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

I'm not sure the energy to weight ratio of 80,000 pounds of batteries to 80,000 pounds of fuel is.

Fuel is about 25 times more energy dense compared to batteries. Of course depending on the fuel and depending on the batteries. 25 times is most diesel fuels compared to most modern li-ion batteries. Large LiFePO4 would probably be used for transport, which do worse than high performance LiCoO2 batteries, so then you are talking about somewhere around 30 times worse. Transporting batteries simply isn't worth doing, it's super inefficient.

Same with stuff like microwave transmission of power, you lose so much in the transfer, it's a total non starter.

Oh yeah, it's inefficient as hell. But energy from the sun is coming to us whether we harvest it or not. It's unlimited. The limitation is solar cells.

We're at the point where we've basically run out of easy oil to access, and we're coming up with bigger and deeper drilling methods. We spend billions on a single offshore rig that will function for 10-20 years at most.

The issue isn't efficiency, it's profit motive.
