Could live with that

No, you are factually incorrect here. Molten salt batteries, as the name implies, are still batteries aka galvanic cells.

Or as wiki itself puts it: > Molten-salt batteries are a class of battery that uses molten salts as an electrolyte and offers both a high energy density and a high power density.

The Ambri cells ARE molten salt batteries, that doesn’t imply anything about the state of matter for the electrodes. The cells have a molten salt electrolyte (obviously, there aren’t many alternatives at these temperatures) and have at least one molten metal electrode. It doesn’t matter if it’s direct electrodeposition or alloying. Likewise Aluminium ion batteries would still be that, no matter if they use tin metal to form an alloy or if they use direct electrodeposition from say an ionic liquid.

And to back it up additionally, see Wiki again:

> Ambri, Inc. is an American startup company which aims to produce molten-salt batteries for energy storage in wind and solar power systems.[1] In 2016 it had thirty-seven employees.[2]

But thermal energy storage by utilizing the infinitely high heat capacity during solid-liquid transitions of salts is definitely a thing as well.

Because there’s no difference between „liquid metal“ and molten salt [batteries]. Except if you use near room temperature melting eutectic alloys as one electrode, the metal melting is merely a „side product“ of using a molten salt electrolyte

Slight correction, it’s less about melting the sodium than melting the salt (the electrolyte) here. Whilst the battery could perfectly handle the electrodes in a solid state, unfortunately most solids conduct ions barely at all - which also is the reason why developing solid state batteries is so hard

Unfortunately not. Recovering the calcium from bones and seashells is extremely costly and labour intensive as the raw materials don’t contain it in the form you want to have it. At the same time we have huge ressources in all sorts of calcium rich minerals and you don’t have to worry about any organic contaminants.

But I could imagine we are using bone meal as fertilizer and calcium supplement

I laughed wayy to hard over this comment. Unfortunately it seems people really have a hard time understanding that. I swear I see posts like „tifu by my parents finding out my gf and I copulated “ (idk if reddit censors or deletes comments explicitly on that, hence the weird wording) where the plot is essentially like: boyfriend stays with gf in one of their parent‘s house, copulate, forget to hide the contraceptives. Parents find out and are mad or disappointed at their children and „have a talk“ and/or forbid them to stay at their house together.

Like wtf do you think college boys and girls are doing being together for half a year or longer at your house sleeping in the same bed? The only thing surprising here is how douchy the parents act. Like it’s 2022 we can stop this whole „no copulation until married“, „bodycount“ and innocence nonsense.

Well that’s fair, can‘t blame you for your opinion here. In this case, thanks for the feedback!

Geez dude, calm down. „Superiority complex“ yeah no, maybe it’s just that I am fascinated by these critters and I felt like I should add it because many comments here are very black and white. But if it boosts your confidence saying that someone has a superiority complex, go on

I don’t get these types of comments to be honest. Neither termites nor roaches are inherently bad, in fact only very few species of each are „bad guys“ because we are creating a habitat for them to thrive in. Most species of termites (especially dampwood termites and fungus cultivating ones) are interesting and harmless, the same counts for your average forest roach.

The article gives little information about the invasive potential of these roaches as you have to consider food sources (types of wood, dampness of wood, mechanism of reproduction (parthenogenesis, inbreeding?) and adaptiveness to abiotic and biotic factors like temperature and competition.

Like, I get it „muh termite and roach bad“ but that does not at all represent the reality
