To clarify for those that think the Jenny would be powering motors directly, He was not talking about a generator to run the car’s motor(s). Only charging the battery bank.
Either way, it’s a novel idea. But using Tesla’s level 2 charging as an example. Level one won’t do anything if you’re burning up battery on a road trip (since this concept is not needed for local driving).
Level 2 is about 80amps worth of charging which puts you in the 10kw generator range.
That’s either a he!! of aload in the trunk or a small tow behind.
Bottom line, if you want to make enough power to substantially supplement the batteries you need a big generator.
If it was that simple, they’d all come with a Honda 2000strapped to the deck lid, but it’s not.
