> And just Tesla set to a high power mode, if when starting to drive it you do max acceleration for 1-2 minute you drain a significant portion of your battery very quickly. An airplane under typical operation has a much narrower ranges of power than a Tesla in high power mode. Takeoff power is a low single-digit multiple of cruise power. For my math earlier I used a 3:1 ratio. A Model S Plaid is more like 50:1, or 30:1 for the "regular" Model S. > The overall point that Im trying to make is that slight battery specific energy density improvements don't matter when compared against the power losses which are proportional to square root of the current. You've completely missed making that point, since I still haven't seen an argument so far that the current must be very high.
