    There are many definitions of an "electric car" I take my cue from how we define hybrid cars. We refer to the fuel when we say a gasoline/electric hybrid car but we are actually referring to the motor that can accept those fuels. If not then every petrol engine car today is a hybrid because they use both gasoline and electricity to operate.

    If an electric car is one that uses an electric motor for changing electricity to motion then the definition of an electric car can include many ways to supply the electricity to the vehicle. We could transmit the energy as we do with trolleys, subways and most electric buses. We could store the energy on the vehicle in batteries, ultra caps or flywheels or we could manufacture electricity on the vehicle with solar panels, fuel cells or an internal combustion engine attached to a generator.

    If by "engine" you mean a device to change energy into mechanical motion then petrol vehicles have an internal combustion engine and an electric car uses an electric motor. If you define an engine as only an internal combustion engine and you accept the above definition and a series hybrids vehicle is an "electric car" then that is the only one that uses an internal combustion engine and only to make electricity.

    An electric vehicle requires energy to move. The fuel is electricity and in SI units this is measured in kWh or kilowatt-hours. The Nissan leaf is rated by the EPA as using 34 kWh / 100 miles or .34 kWh / mile. Watts are volts times amps. If you increase the voltage you will necessarily be decreasing the amperage (or increasing resistance) but you are not going to be pulling energy from thin air.

    To increase the mileage you have to increase the efficiency of the electronics or decrease the load/resistance with things like reducing aerodynamic drag, rolling resistance or lightening the vehicle mass. Tesla claims that the roadster is over 92% efficient from battery to wheels. ... not a lot of room there.

    Yes, they have engines, but not like gasoline cars. The engine is simple, and in the form of an electric motor.

    Its moving power comes from DC motor.

    You were totally lost on principle of Op-amp. Amplifier into a higher voltage requires higher voltage power source to supply Op-amp.

    you're a dreamer and not the only one. gas vehicles and trucks replaced electric powered vehicles as quickly as already. It grow to be neck and neck on the turn of the final century. What approximately absolutely everyone outdoors your city? Tractor trailers? think of of the distances in the midwest. besides your city could get purifier, yet whoever has a potential plant of their city gets dirtier, there's no ZEV. photograph voltaic is in basic terms too far off, and there could desire to never be adequate of it. Do the mathematics.
