We know from the WK hack that XP100D is coming, but in what form and how? The discontinued Powerwall was the EPS 10kwh version...so, could the new version, expected soon I think, have all the inverter circuitry to feed power outlet sockets (like the wall sockets in your house) and at the same time be hard-wired to the charging circuits and drivetrain circuits of the car and sealed under the floor in that deep recess right at the back of the X? (Sorry if I've missed some company news that contradicts such a possibility. I am also wondering if the Model Xs delivered so far might have provisions like wiring harnesses and attachment lugs already in place for retro-fitting the missing 10kwh. Cell type is important, too...IIRC the EPS Powerwall had the same chemistry as the battery back. I'm uncertain on all these points. Perhaps someone will comment?) Ever the optimist, I'll go on as if this were plausible... Effectively, you would have a very useful EPS in the back of your X. All you may need is a very long extension lead to run it inside the house to reach appliances you want to plug in during a power outage. Also, you can run all manner of household appliances and power tools from your X when you are out and about. Then if the above is possible, it begs the question: Will the M3 Performance package be furnished with the same new Powerwall replacement device? Again, if the answer is yes, it provides a very neat fit with my wish list for TM: If TM wants to massively boost the number of early reservers (as I speculate it does), then all the company need do is have a cut off date for reserving the performance version, after which reservations may only be converted to lesser variants. (It will be years before they are all supplied anyway, by which time new models will be on offer). Fortuitously, the reservation deposit is completely independent of configuration, Performance or otherwise, so potential reservers all over the world will say to themselves..."Well, I don't want the performance version because of the expense, but hey that's a neat EPS feature, and it costs nothing more to get in line for, and of course I can always cancel and walk away from the whole thing, so I have nothing to lose and everything to gain by going online right away to reserve before the cut off." Consider also how TM ramps new models...always the highly optioned high ASP variants first. A cut-off date is a great marketing tool to force all the high ASP orders to the head of the line. The lesser optioned and base models with lower margin can follow later, when the factory is really humming along efficiently. It's neat. First one configuration of the production line then another, so a less complicated factory. This method of massively boosting the incentive to reserve, does not depend on discounting or 'bonus' or 'freebie' notions that I wrestled with clumsily in the "What if.." thread I started a couple of days ago. Moreover it lays to rest all the problems that thread threw up. Thanks to @Johan and @Fallenone who went there to comment. I was thereby stimulated to start again with the idea for this thread, further along the chaotic path from an absurd idea... thru ridiculous... thru nonsense... thru very unlikely... to plausible perhaps? .... That's it....a little food for thought, but only for tonight and tomorrow!
