  • Yeah they can’t match top of the line Li-Ion like lithium-cobalt batteries. Neither can LFP, but LFP is good enough for lower range EVs cars as they’re already used in such. Sodium ion has even lower density than LFP but not dramatically so and it’s still early days so their density is likely to improve. Look at these two cells currently on sale:

    The first one is a CATL-made LFP. The second is some smaller manufacturer’s sodium ion. The 729Whr vs 713Whr, 1944cm³ vs 2593cm³. If the sodium ones can be made cheap enough, these are already usable in low range vehicles like Nissan Leaf or equivalent. And then there’s buses, trucks, other ICE powered equipment.

    The process through which we get more users is that something material changes in current Tirefire user’s life that puts them over the threshold needed to look for alternative. Then they look. Lemmy is the obvious Reddit alternative, it’s well indexed in search engines. Then they try it. If the quality of content is decent, there’s a decent chance they stay. They know the quantity won’t be as high, that’s the major reason they haven’t switched to begin with. So for this process to keep functioning, we need to maintain the quality.

    Of course we should also suggest Lemmy, but probably when asked or otherwise appropriate. Or else it may have the opposite effect that naked shilling often has.
