perhaps i was not clear in this thread or elsewhere, but i know that battery electric is bull****. my proposal was to use a gasoline or diesel engine or some other ICE operating at peak volumetric efficiency generating the electricity in the car itself and eliminate the ATX and mechanical drive train. marine propulsion as well as rail transportation has used diesel electric for close to a century. electric motors have full torque at 0 RPM. my experience as a marine pilot is that these are some of the most efficient and controllable setups available. using my proposed setup, you eliminate the ICE running at inefficient RPM's due to the realities of driving. there are losses in the transmission and drive train due to friction and these are hard limits. add in the near ubiquity of 4WD and more efficiency is lost to internal friction. there are also the issues of rotational acceleration and momentum of the drive train components. 4WD is mostly unnecessary, but you can have your cake and eat it too if you drive each wheel electrically. the level of control that you would have would be great.

so to clarify, battery electric is a bad, illogical and downright criminal waste of resources at least in my opinion. this tech will screw us over if it becomes prevalent. i would like to see Tesla's drive train paired up with its own electrical generation, in other words a generator under the hood, no battery ****, no electrical transmission costs, no charging losses, no battery deterioration.

And a lot of people do not account for the fact that the deterioration of the battery makes the car useless a lot sooner than an ICE vehicle. you can replace or rebuild major parts of an ICE car for less than the battery replacement, not to mention how energy and resource intensive battery production and recycling will be.
