Sodium ion batteries go boom (and fusion goes bust)

 That bloke who runs the Youtube channel "Just Have a Think" has had a couple of particularly interesting videos recently related to energy.  The first is about apparent advances in using sodium ion for batteries instead of lithium (which seems great news if it pans out, unless you've bought stock in lithium mining companies):

 

 There have been quite a few other videos floating around in my recommendations about this, but I haven't watched them.

 The second one is a sceptical look at fusion, building on the information Sabine Hossenfelder put out in a video he references: 

 

I am a little surprised, actually, that Sabine still says that its technology worth looking into - I would say it is, within certain economic limits, which must be just about reached with ITER.
