Great post... Thanks!
Just a few quick thoughts--

I do think a 'swap' infrastructure is viable- but that we'd be smarter to be patient and focused on solid hydrogen ('fuel' exchange model) rather than battery (entire 'storage' device) -- to keep things more simple.

I'm not a kool-aid drinker w/ hydrogen. I know the materials science challenges quite well and remain very optimistic w/ solid state storage and cost/performance advantages of fuel cells around nanostructured design of key components.

Swapping lighter weight solid H2 blocks (e.g. MOFs) treated as 'fuel' seems more reasonable than entire batteries.

And a be yes(!) to the notion of EVs for new vehicle/transportation categories. I think we're better off keeping coming generations of plug in EVs as urban fleets designed around 'on-demand' service models rather than try to immediately replace the family car. So I'm very glad to see Sue Cischk thinking beyond just selling new cars. Let's innovative around software and service-- and be patient!

Thanks for post...

Why would anyone do a road trip? If I need to go more than 125 miles, I fly
