Electricity from batteries comes from public utilities which in many cases are fuel fired steam generators. Battery technology and mass productions would bring down the cost and they will always be in demand for road vehicles for auxilairy power and start up.
The unsprung total wheel mass issue is one of AC/DC hub motor design. If the motor is comprized of simple disks and not the common stator/rotor coil concept the mass is greatly reduced. With the use of carbon composite and very high field permanent magnets associated with flat stator coils the motor becomes a little less heavy than a standard brake disc.
Check out the web site for Phoenix Navigation (PNGinc) and Tesla Turbine Pulse Combustion project. The emmissions from this turbine concept are practicaly zero. My point is time to market for developement of an extremely simple turbine motor/generator concept. If one wants to boost output of this turbine, water can be injected just after the pulse combustor (PDE) chamber. HT superconductors are coming on market at reduced prices due again to market volume. Note that only the motor/generator has ht superconductor stator coils. The increase in current output thus achieved more than offsets the slight additional cost of the ht superconductor tape or carbon nanofiber.
Tesla gas turbine engine with integral motor/generator was the intended Tesla device:
The application I had in mind is under study by NASA as outlined in DOC TM-2005-213800 for aircraft engines. Under contrat is SatCon for an ht superconducting augmented turbine. The concept of an augmented Tesla gas turbine with integrated AC motor generater (I prefer DC) offers very light weight and extreme simplicity of design. I am aware Tesla was the father of AC.
If the Tesla roadster utilized such a device with no power transmission/drive line and used AC or DC hub motors a weight to torque advantage could be realized. LNG or Hydrogen or propane fuels are available as I write. With reguard to AC or DC application in automobiles, DC has been used by the US auto industry as you well know. Jump starting the EV industry with batteries, with their enormous expense, is not likely to set well with the average driver. A Motor/Generator turbine on the other hand might catch on.
If it is a TRUE Tesla roadster you seek try this: Tesla turbine/electric hybrid with four in hub DC motors. A Tesla turbine with ceramic permanent magnets on turbine rotor and ht superconductor stator coils mounted in foam on cooling fins on turbine case. A power control computer and a 12VDC battery link with the motor/generator to start turbine and supply current to DC drive motors. PDE combustors supply high velocity gas to drive the turbine using LNG fuel or Hydrogen. LN2 from a thermos bottle size supply to cool ht superconductor completes the basic elements for the TRUE Tesla roaster.
