Build an all-electric car

Understanding
An all-electric car is a road-worthy vehicle that is powered entirely by an electric motor and some kind of battery, capacitor or solar cell. It can be assumed that such a car would not use combustible fuels as a power supply.

The electric motor transfers power from its rotating axis to the wheels via some kind of gear box.

A Tesla Roadster is an example of an existing all-electric car. Most of its performance is comparable to a typical high-end sports car (citation needed). Completing an imitation of this vehicle would therefore be rather controversial and would attract quite a bit of media attention if it were built according to the instructions presented in the method section below. This media attention would also attract more people to help in the completion of this problem page which may speed up the development of an open source all-electric vehicle.

A two-seater would be a reasonable first choice for the number of seats in the car because certain versions of the Tesla Roadster have two seats.

Further information about the Tesla Roadster can be found here: http://en.wikipedia.org/wiki/Tesla_Roadster.

that seats two people

 * 1) Decide how it should be built.
 * 2) Find a company that sells a 3-Phase alternating current induction motor like the one used in the Tesla Roadster.
 * 3) Describe an aerodynamic or functionally-useful shape as the guiding shape for the body of the car:
 * 4) Use Microsoft Paint, or something more appropriate, to make 2-dimensional or 3-dimensional sketches that describe the shape of the car.
 * 5) Use Google Sketchup to design an aerodynamic shape for the car.
 * 6) Upload these files to Substepr for other users to download:
 * 7) In the left menu at the bottom, click on the 'Upload file' link.
 * 8) Browse for a file to upload.
 * 9) Upload it.
 * 10) Determine the best lithium ion battery to power it, or...
 * 11) Determine the best supercapacitor to power it, or...
 * 12) Determine if a different power supply to the previous two examples would be more suitable.
 * 13) Build it.
 * 14) Assemble the chassis.
 * 15) Thread the axles onto the chassis and fix them in place.
 * 16) Put the wheels onto the axles but don't put the tyres on the wheels until all of the metal work is complete.
 * 17) Put the engine into the chassis and fix it in place.
 * 18) Attach the power supply to the chassis.
 * 19) Install the steering column and steering wheel.
 * 20) Install the electronic control systems that translate rotations of the steering wheel into rotations of the front wheels.
 * 21) Install the brake and accelerator foot pedals.
 * 22) Put the tyres on the wheels.
 * 23) Install an electronic sensor for the brake pedal and link it to the control system so that pressing the pedal leads to hydraulic brakes being activated.
 * 24) Install an electronic sensor for the accelerator pedal and link it to the control system so that pressing the pedal increases the voltage or the "on-frequency" or the "on to off ratio" of the pulse width modulation to the electric motor (thus increasing the power to the motor).
 * 25) Install any additional electronic gadgets such as radio, speakers, satellite navigation, air conditioning and temperature sensors for indoors and outdoors.
 * 26) Install the interior such as the seating and surface finishes.

Everything else
Note that the title "by mimicking a Tesla Roadster" should be read as a continuation of the command in the title of this page. The same applies to the subheadings.

The effective voltage to the electric motor could be increased or decreased electronically through the use of pulse width modulation (as described here: http://en.wikipedia.org/wiki/Pulse-width_modulation).
