I have been speculating about a relationship about a year and a half ago. Elon gave a hint with the "sustainable lithium ion production at the giga fab. More then 6 months ago Elon hinted at the same chemistry and form factor for the home storage solutions during the earnings call. Since then nothing that supported links between the two companies. So I am excited to learn what happend behind the curtains if anything...
Get excited - bought some popcorn for tmrw...
