I don't have time to delve into this today, but that's no reason not to kick off the discussion. Tesla is announcing Battery Swap, and if its automated (as I expect) there are real potential issues. Above all else is reliability. Nobody wants to get stuck on a SuperSwapper with the baby half delivered. So what is our model? Elevators? Car Washes? I hope it's not rollercoasters. What data do we have? Did Better Place publish anything? I'm not really interested in whether its possible. Tesla has claimed the capability from the beginning, and Better Place built a working system which did not fail (to my knowledge) due to technical problems.
