Using the distributed network available from millions of parallel EVs using GPUs for cabin heating could perhaps bring about practical realtime adaptable AI, observe road conditions realtime and reroute traffic around troublesome or dangerous road conditions, potentially saving lives, solve otherwise intractable societal problems while heating EV cabins to comfort levels.

What if… we wanted to retrofit EV cabin heaters with GPUs, either to mine bitcoins or beat commies or whatever else this imaginative ExI crowd dreams up. We don’t need Nvidea’s latest and greatest product, and there are good reasons to not use those anyway, directly related to cost. Reasoning: the power cost per… bitcoin(?) out-computed commie (?) contribution to the singularity (?) AI trained (?) is too high for the most modern GPU, which is priced up because of demand outstripping supply. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I recall from the olden days when outdated processors were so cheap, the factory would give them away (Motorola would give students a box of first generation M6502 bare processors if we wrote them a letter asking for them and explaining what we were doing with them (this was back when the obsolete but still functional first gen 6502s still cost five bucks at the electronics outlet (this was a big help (we didn’t have five extra bucks in those brutally impoverished days (resulting in our not having communicable diseases, permanent injuries or a criminal records now (we couldn’t afford any of those back then (or the obsolete five dollar processors either.))))))<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Now the idear evolves from Ben’s comment into this: what is the right GPU, if we consider cost and space restrictions in an EV cabin heater envelope? I don’t know the dimensions of the non-Musk EV cabin heater envelope or where it is, but I am specifying non-Musk because I already know those places have pleeeeenty of wide open charging facilities, whereas I don’t know if the Musk chargers are as easily available. I have heard Muskmobiles are not designed to be owner-repairable, so it isn’t clear to me that it would be practical for a Musk EV owner to replace the heater coils with GPUs.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Have we non-Muskers who can check their EVs?
