I like the idea from a technical perspective – always having a spare battery at home charged up and ready to go – but I’d be concerned with the cost of the extra battery and the packaging hardware to make it easily swappable. With today’s technology, I still think the ICE / Generator and supporting hardware is cheaper and more convenient (i.e., gas stations everywhere).

Any statements against the feasability of swappable vs fast charging vs (yours) should be delayed. Unless you like being proven wrong. I do not think anyone knows at this point. Lets try everything, Winner Take All. I do not want to run into incompatibly issues like with my inkjet. As long as there is 1 WINNER like gasoline! (oh, does diesel count as gas?) ok, 2 closely related winners for simplicity. The industry is still working on a “automotive” battery.
