I. INTRODUCTION

In my view, a modern insanity is the use of internal combustion engines to drive the wheels of a car. Using an electric motor to drive the wheels is simpler and more efficient because electric motors don't need to shift gears. They have good power or torque at all speeds. Just flip a switch and the motor runs in reverse.

Also, electric motors are much simpler devices than gas engines. They have basically one moving part, whereas gas motors have hundreds of moving parts that wear out. For this reason, electric motors are more reliable and much cheaper to build and maintain.

HOW TO PROVIDE ELECTRICITY TO RUN THE CAR

Batteries. One can use batteries to power the car. This is called a pure electric car. Tesla cars and some others use batteries. Batteries are heavy and recharging them is somewhat slow. They also wear out in a few years and must be replaced.

Also, government regulations at this time prohibit the use of lead-acid deep cell batteries in cars. These would be much cheaper than lithium batteries, which cost at least four times as much as lead-acid batteries. Once again, someone does not want us to have simple, inexpensive electric vehicles.

Hybrids. This is a combination of an electric motor to drive the wheels and some type of gasoline-powered or other device to generate electricity for the electric motor.

The simplest method is to have a small gas motor turning a generator to produce electricity. However, government regulations in America and elsewhere prohibit this excellent arrangement. The regulations say that in a hybrid car both the gas motor and the electric motor must be able to drive the wheels.

This regulation is completely ridiculous. It makes hybrid cars expensive and complex - and that is obviously the goal.

Internal combustion engines that today are used on most all cars are very inefficient. Here are other options:

An oscillating motor. Nicola Tesla invented a two cylinder oscillating motor that was extremely efficient, much better than today's reciprocating internal combustion motors.

Turbines. Nicola Tesla also invented a bladeless turbine engine that would fit in the glove compartment of a car that generated 200 horsepower! I rode in a turbine car at a world's fair years ago. The problem with the one I rode in is that it was a direct drive and had poor acceleration. A hybrid turbine/electric would solve that problem.

Steam engines. I also witnessed a steam car some years ago. It was a huge old Pierce Arrow. It went fast and was completely silent. Steam engines are gas-powered engines that are external combustion engines. They are much cleaner running than internal combustion engines and more efficient, too.

Other. One could us solar cells or fuel cells to generate electricity. One could also use more high-tech methods to produce electricity such as etheric power. Nicola Tesla also had a large Pierce Arrow car at one time that ran completely on etheric power.

Etheric energy is free, safe and environmentally clean. However, this method of producing electricity is prohibited on earth today.

Clearly, someone wants the earth polluted with gasoline fumes and wants us spending our money buying gasoline and buying and repairing expensive, polluting cars.

Today's Tesla automobile is named after Nicola Tesla, a name everyone should know. For details, read Nicola Tesla.

Here is a more complete list of reasons to use electric motors to drive cars.

II. ADVANTAGES OF ELECTRIC MOTORS TO DRIVE CARS

1. A much simpler transmission! The reason is that electric motors have excellent power at all speeds. The typical gas motor only has good power in a limited speed range, so it must shift gears all the time to maintain the proper RPM of the engine. Transmissions add a lot of cost and weight to a car. They also reduce its power and efficiency.

2. Electric motors are cheap, simple, clean devices with basically only one moving part. Gas motors have hundreds to thousands of parts that can break. They are among the most complex machines on the planet!

This means that electric vehicles are more reliable and much less costly to begin with and much less costly to maintain. No changing oil, no changing transmission fluid, no tune-ups and other money-saving aspects.

3. Longer-lasting. I lived for a few years in Boston, Massachusetts. They have electric trolley cars that run from the city to the suburbs. I found out the same trolley cars have been running for 100 years! Gas motors tend to fall apart much sooner.

4. Electric motors run quiet, clean and fairly cool. As a result, they require simpler cooling systems, and no anti-pollution systems or mufflers are needed. All this saves money and weight, and reduces repair costs.

5. Electric motors are much more efficient. This means they use much less fuel to operate than internal combustion engines. Internal combustion engines are about 20% efficient. The efficiency of electric motors is 90% or more.

This means that even if we have to burn oil to generate the electricity to run the cars, it would be half as much because electric vehicles are at least twice as efficient as internal combustion engine cars.

Sixty years ago I read about a hybrid car design in the Mother Earth News that got 100 miles per gallon of gasoline! Today's hybrids are not that good because of stupid regulations (explained more below).

6. Safer. Gas-powered vehicles can easily start on fire and they occasionally do. Electrics do not have this problem.

7. Many electric generation options. We can use oil or natural gas to power some power plants. But one can also use hydroelectric power, solar power, wind power or other methods to generate electricity for the electric cars.

8. Tricks with electric cars that further increase their efficiency.

- The best trick with a hybrid gas/electric vehicle – battery backup. 80-90% of the time, it takes very little horsepower to power a car. With just a gas engine, one must lug around a big powerful engine in case one needs more power to climb a hill or pass a car or for rapid acceleration. This adds weight to the car and uses more gasoline.

With an electric drive, one can use a much smaller gas motor (half the horsepower or less) and have some cheap batteries (not lithium, which is costly). If more power is needed for a short time, one just draws on the batteries to obtain extra power. After one climbs the hill, the batteries recharge. A smaller gas motor means less weight and better gas mileage.

Battery backup has other advantages. If the gas motor fails for any reason, you can still drive a certain distance on battery power to get help.

- Regenerative braking. With electric vehicles, when one stops accelerating or steps on the brake, the motor can be turned into a generator and you can recharge the batteries. This is called regenerative braking. It works well and most electric cars offer this.

- Solar recharge. One can put solar cells on the roof to recharge the batteries all day long. If one lives in a sunny state, one might rarely have to recharge the batteries in the car. However, this is illegal in America. Obviously someone does not want us to have good electric cars.

- No warmup needed. People waste time and fuel warming up their gas-powered vehicles in the very cold areas. There is no need for this with an electric vehicle.

- No idling. With an electric vehicle, the motor turns off completely when one stop at a red light or stop sign. This saves energy. In a gas-powered car, the motors continues to run at every stop light. This uses up gas and pollutes the air even when you are not going anywhere.

SUMMARY

In summary, using electric motors to drive cars is a simple and excellent idea. I am saddened that some conservative people try to find fault with this idea. It would save a lot of money and oil. Cars would cost half of what they cost today and last much longer.
