3 months agoIIRC, the reason sodium batteries would be better is we have abundant stocks of sodium, whereas the raw materials for most other batteries are limited and require more destructive mining. John Oliver just covered some of this on his show last Sunday. If that tech can be improved, hopefully there won’t be any deep sea mining for more raw materials!
While I can concede your point that it’s feasible and possibly even more practical to open from the stem, I gotta say that since switching to the other end years ago(because I saw a similar thread on reddit), it’s been super easy and I’ve had zero issues. The stem just has a higher rate of fucking up, but it’s not like either end will fully decimate the banana. Peeling properly after it’s opened is an easy fix either way.
