We have less than two weeks to build an electric car in class. Our energy sources are two AA batteries. The Chassis size is 12 cm X 30 cm. The driveline options are gears, pullies, wheels, chains, propellers, etc. It also must have an on or off switch. I'm not very experienced in this field so any recommendations on how to get this all to work is greatly appreciated. Thnx :)

There are plenty of instructions on the web. You just have to know how to search it. Try these:

The main trick with any of these is going to be finding the parts in a limited amount of time. You may have to see what is available locally rather than on the web. Look in a $1.00 store for a hand held battery fan for a motor. It won't have a gear but you might be able to use the fan to power the vehicle. Good luck

My wife wants to buy an electric car.?

In this part of the country there are not many of them. Have you owned one and how did you like it. How often did you plug in your car, everyday or after the 50 miles were used?

If you have owned one, would you purchase a second one or one to replace the one you already have. I am trying not to have this be a political discussion. I know the rumors. I just want someone who has owned one to tell me their experiences
Answer
You have to start by answering the question, "What do I need to get out of the vehicle?"
If your primary use is just to put around town like take the kids to school, run down to the grocery store, commute the 5 miles to work you can get way with a Neighborhood Electric Vehicle (NEV) or some times called Low speed Electric Vehicle (LEV). The cars are limited by law to 25 MPH (35 MPH in some states) but they recharge from any outlet you can plug your cell phone in.
If you need to take to the highway your options become severely limited. Currently the only highway speed EV available to the public is the Tesla Roadster at $120,000. Everybody else "is working on it and will be ready by 2010".
You don't need a 300 MPC (miles per charge) electric car. When you get home after a hard days work, you plug in the car, eat dinner go to bed. In the morning you get up, get dressed, unplug the car and leave every day with a full load of "fuel". Two minor additions to the usual routine and you've made the world a little better. A gas car doesn't self fill at night an since you don't want to visit the gas station on a daily basis 300 miles is a light range requirement.
The length of the charge time at night is irrelevant. I'm asleep so what difference does it make if it takes 1 hour or 6. Think how many hours a day is your car actually being used out of 24? The rest of the time it is just sitting, waiting for you to use it.
As for plugging it in everyday, don't you plug in your cell phone every day to charge it? An EV is the same deal, put the car in its parking place, hop out plug the cord in, go in and eat dinner. The rest is automatic and baring some kind of minor catastrophe your car is ready to go in the morning. You can also plug in wherever you stop, called opportunity charging, if your vehicle has a 110 volt charger. Since 80% of people put less than 40 miles on their car on a daily basis a 50 mile range isn't an inconvenience.
