Two things:
IBEX 2025 Electric (Cudes posted it as 2024 before he took it down. I'm sure by accident, so here you go Cudes, fixed now. Not sure why you took down your post. The video was a good primer on the state of things... after a little clarification).
This is the video about eight minutes: https://youtu.be/CQ1J3numR1k?si=3xVv62cCn1nmIf49
1) most of the video was centered around motor innovations, which are fine, but not impressive because electric motors are already well into the ninety percent efficiency range. I suppose the small tweaks to make them stand up to water and worse, salt water, are worthwhile things to get done... IF... a useful energy storage medium ever comes along. (some of the videos of BEV tow vehicles catching fire at salt water launch ramps are impressive, so making high current electrics hardened against water and corrosive water is definitely a worthwhile pursuit).
2) But... the last few minutes talked a little about the elephant that is still firmly in the room... but it was done in a very surfacey, marketing-misdirection'ish way. IOW, not much math. He said something to the effect that "this battery weighs about as much as gas tank full of fuel", or some misleading thing or another along those lines, drawing the listener into a sense of false equivalency. What he doesn't say, and giving him the benefit of the doubt because he probably doesn't know, is that that 400lbs of petrol has 51 times more energy (at least) than 400lbs of battery.
So, the elephant in the room here, has not changed.
It's remarkable how close marine propulsion batteries weigh per unit energy, so Tesla's mondo 100KWh battery... And not surprisingly (to me), how much it has NOT improved over the past four years or so that we have been going rounds on this topic. We can get into why this is so, if anyone is interested.
