renewable energy systems

i would like an all electric auto to have a range of 450/500 miles. not all pure electric vehicle owners would want or need this requirement , so its' capability would fall into an accessory/add on item.

there are two ways that this can be achieved with existing technologies. the first is with solar panels integrated into the roof , hood , and deck surfaces.

the second is with wind power (i can provide diagrams and schematics). to describe the basic system simply . . .take two spindles , laying flat , with an electric generator at the end of each spindle. place these in ducting running fore to aft below vehicle ,ala, an "exhaust" system. use a variable bladed system on the spindles to catch the airflow and drive the generators.
