There are many kits online you can buy to convert you're car from gas to electric. They are around $30 and fairly easy to use. Everything is included, including easy to follow instructions.
The Chevy Volt uses gas to power an electric motor.
Converting a gas dryer to an electric dryer is not recommended and can be dangerous. It is best to purchase a new electric dryer instead of attempting to convert a gas dryer.
A electric car is a car that only uses electric instead of gas.
Get a gas powered motor and connect where electric one was.
There are no internal combustion engine parts in a electric car. The Electric car will not use gas but electricity from batteries.
No, it is not possible to convert a gas dryer to an electric dryer as they operate on different energy sources and have different internal components.
With the help of a DIY EV conversion ebook, it seems that anyone can make the changes necessary to convert their car into an electric vehicle. An excellent article at http://www.ev.com/ev-components-parts/diy-electric-car-conversion-kits.html is very informative on this subject.
The gas car won over the electric model because of its higher power output. Gas is much cheaper and efficient than comparable electric engines.
There are no refueling stations for electric cars, as none are in production this is not an issue. The range of an electric car is still too short to make them usable for most of the planet. Hybrids are normal gas powered autos that convert power to electric before it moves.
The "...convert a gas car to electric..." implies removal of the gasoline engine and replacing it with an electric motor, creating an all electric car. If on the other hand you intend to keep the gasoline engine and use it when the batteries are low, then you will have created a hybrid gasoline-electric vehicle. With that qualification, and the assumption that you meant a full conversion from gasoline to electric, then the answer to your question is that IF the gasoline engine is removed from service, then the computer "that controlled the gas engine and its components" is no longer necessary and can be removed also. Also, the portion of your question relating to the gasoline engine computer suggests your thinking that it could be reprogrammed somehow to control the electric motor. Since that computer is designed for and is dedicated to the gasoline engine, it cannot be be reprogrammed and used to control the electric motor(s).
Electric
With gas power, gasoline is a fuel which burns inside an internal combustion engine, producing power to move the car. With an electric car, an electric battery generates electricity which is used to operate an electric motor which moves the car.
