I've seen analyses (Thunderf00t) that seems to suggest that battery energy density is already near physical limits and not to expect any significant improvement.

It reminds me of when Ethernet went to a crazy tri-level signaling scheme to barely eke out 100Mbps over Cat 5 cable. That was unquestionably the physical limit. Until a few years later when it was somehow magically up to 1000Mbps over Cat 5.

A Zero uses less energy to go the same distance at speed than an Energica, Don.

Quoted range?

The bikes are heavier and use less efficient linkages that turn some efficiency into power?

Sorry didn't mean to start a Zero vs. Energica rumble. I was thinking what's the new tech look like. The video was very informative: lots of movement towards solid state, maybe will be in vehicles in 5 years, but if it's so great, why isn't industry leader Tesla going there?

[Crissa]

Tesla is focused on optimizing their factories so they can get cars out the door.  Right now they're two steps ahead of the competition, having planned to build, and having built, battery factories to not hit limits on their production.

Even if we're see solid-state become commercially viable in five years, there are still five years of cars to build in the meantime.  And Tesla has been burned by battery companies touting their contacts with them in the past, so they probably keep their timeline close to the chest.

It is a good thing that we live in a day of electricity and not horses:
