The Tesla hipsters convinced me that Elon intentionally defeated such an absurd notion, disallowing any charging in flight, damn.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Seeing a Tesla towing a boat on a road trip recently caused me to revisit the idea with a fun twist. What if… we rigged up a trailer with its own battery or even a big Diesel generator with its own motors on its axles? Then a prole hitches up her Tesla, gets it out on the freeway, fires up the Diesel which drives the trailer wheels aaaannnndd… gently pushes the Muskmobile along the freeway, extending battery life?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Wait, before you point out to me what I already know… that such a goofy notion would result in oscillating instability, because it would become the equivalent of a negative tongue weight on the hitch… ja, I realize that. But, we are not busted, necessarily, not yet. If we were to get tricky with sensors on our hitch, and we had plenty of power on the trailer axles, and we dial in plenty of moment of inertia in the trailer about the vertical axis, and we are hot with our digital controls… if all that, I bet we could make an active control system that would keep that coupled pair going headlight-end first down the freeway, and could even maybe go a longer distance than an uncoupled Muskmobile.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Anyone here think that might work?
