75 kg rider weight limit? I feel personally attacked.

[–] BearGun@ttrpg.network 12 points 2 days ago

I feel like 80% of men weigh above that lol

[–] poVoq@slrpnk.net 6 points 2 days ago

Especially ironic to install a backseat for a second person on a scooter with such a low weight limit.

[–] Pickle_Jr@lemmy.dbzer0.com 3 points 2 days ago

Damn and here I was proud of my weight loss. 40 more pounds to go I guess 😂

(For us Freedom Unit folks, 75kg = 165lb)

A big advantage of its sodium cells is also the fact that they can retain more than 92% of their capacity even when operating at -20°C (-4 Fahrenheit) and discharging at those freezing temps.

That is very promising to hear. My current vehicle, which uses first-generation lithium batteries (made on 2011), loses almost half of its range at that temperature, and that is before heating.

its speed is limited to the 25 km/h

Pass.

Also, tried their website to find a dealer and it was straight cancerous.

Loving the battery tech though. Hoping something affordable like this makes it to my area.

Excited to see more capable implementations of the tech.

Reminder to never be an early adopter of a new technology unless you are willing to pay the early adopter fee when its outdated next year (or month).

So many compromises, but it's only like $500.

Is the ratio of salt produced as a byproduct of desalination of ocean water out of whack compared to the amount used in battery production?

[–] Diplomjodler3@lemmy.world 23 points 2 days ago (2 children)

Sodium is a resource of which there is absolutely no shortage. The stuff is pretty much everywhere.

It sounds like the perfect match with solar panels

[–] sploosh@lemmy.world 1 points 2 days ago

If only we could get photons to knock electrons off it.

[–] Tikiporch@lemmy.world 0 points 2 days ago* (last edited 2 days ago) (1 children)

Totally. But what if we left it where we found it?

I get the economics of the situation (capitalism, etc) , I'm just saying...if there is salt already safely and naturally found underground or on a salt flat, why not leave it there and use this byproduct salt that we don't know what to do with?

[–] Diplomjodler3@lemmy.world 3 points 2 days ago

There are plenty of mining processes where salt is a by-product. That goes for desalination as well, of course. Salt for batteries will always be a tiny percentage of overall usage so this is not really a significant use case.

[–] PuddleOfKittens@sh.itjust.works 11 points 2 days ago (1 children)

There are salt flats and salt mines, which are potentially cheaper than desalination (they're literally just digging up the ground and putting it into a truck), but desalination also has a huge excess of salt that ends up being dumped into the ocean; more sodium demand would be good for the environment.

[–] BearGun@ttrpg.network 4 points 2 days ago

Iirc, the problem with desalination is that it doesn't actually produce salt, just a very salty water slurry. So for them to produce usable salt they'd have to dry it out or something. Not that that sounds like it would be particularly difficult, but it's an extra step.

[–] GissaMittJobb@lemmy.ml 2 points 2 days ago

As far as I know (which is not a lot in this case), salt isn't really harvested from desalination, and instead the concentrated salt solution (brine) gets deposited back into the ocean, where it can be damaging to marine life in the vicinity of the plant.
