Hybrid Cars



What is a Hybrid Car ? To explain about hybrid cars simply, while normal vehicles move with gasoline, hybrid cars drive with gasoline and electricity, so they save lots of gasoline. In addition to that, since Hybrid cars emit nearly zero exhaust fumes, they are good for the environment, because they reduce emissions that contribute to global warming. As global warming has been getting much more serious, reducing carbon dioxide becomes the highest priority for human beings. Hybrid cars are expected to reduce the consumption of gas.

Mechanism A hybrid car is equipped with a battery, an inverter , an electric motor , a generator and a gasoline engine. When a hybrid car starts, electric power from the battery goes through the inverter and moves the electric motor. When a normal car starts to move, the gasoline engine spends lots of gasoline, and makes exhaust fumes and carbon dioxide. On the other hand, a hybrid car moves by the electric motor with electricity at the start, so it saves lots of gasoline, moreover, it does not make any exhaust fumes and carbon dioxide. As additional power is needed under normal driving conditions, the gasoline engine automatically starts, and works with the electric motor simultaneously. When breaking, the gasoline engine automatically stops, and the energy from the breaking system supplies power back to the battery, so the battery never needs to be plugged in. Hybrid cars charge their batteries themselves. They are absolutely ** fuel efficient cars **.

History 1886 Karl Friendrich Benz, a founder of Mercedes-Benz, produced the first gasoline engine car in Germany 1896 Ferdinand Porsche （Mercedes-Benz now ） produced the first hybrid car in Austria.



1900 In New York, 2300 vehicles were registered. Of those, 1170 were steam engines, 800 were electric, only the remaining 330 were gasoline. 1915 Woods Motor Vehicle (1899-1916) produced a hybrid car with an engine and a motor. Maximum speed 55km/h (Gas engine technology developed dramatically, so hybrid cars declined) 1982 Mercedes-Benz re-started to produce hybrid cars, but they just tried out. 1997 Toyota produced a hybrid car. It is the first usable hybrid car.(Prius) 1999 Honda produced a hybrid car.(Insight)

Advantages
 * __Environment-friendly __ : The biggest benefit of using hybrid car is yhe contribution to the environment.Hybrid cars emit less exhaust fumes and carbon dioxide, so it reduce greenhouse gas.
 * __Efficient performance __ : The engine runs on both gasoline and electricity. The engine is controlled by the computer, so the driver does not have to switch manually.
 * __Better mileage __ : Hybrid cars have better mileage. we compared the gasoline cost between normal gasoline engine car and hybrid car.

A driver drives 12,000km in a year on average( Gasoline $1.1/L) ☆Hybrid car saves $917 in a year

Disadvantages
 * __<span style="font-family: Verdana,Geneva,sans-serif; font-size: 130%;">Cost __ : When you purchase a hybrid car, it costs 20% more expensive than a normal gasoline car.
 * __<span style="font-family: Verdana,Geneva,sans-serif; font-size: 130%;">Maintenance __ : Hybrid cars are 15% heavier, so its tires get damage faster. Also, when a hybrid car gets damage, it need to be taken care of by experienced mechanics, for the computer controls the engine.
 * __<span style="font-family: Verdana,Geneva,sans-serif; font-size: 130%;">Runs too silently __ : When a hybrid car starts, it moves by the electric motor, so engine produce very little sound.Because of that, pedestrians are unaware if a hybrid car is coming towards them.

The future
 * [|Nissan] announced that its 2012 Infiniti M35h would be the world's first hybrid to come equipped with standard pedestrian warning sounds. Other hybrid makers seem to be moving in the same direction.
 * [|Honda] has focused its hybrid marketing strategy on making hybrids by swiftly moving to put [|lithium -ion polymer batteries] in the hybrid cars. They are flexible and low cost. Lithium-ion polymer batteries might be the key to making standard hybrids more affordable.
 * Some transportation such as trains and buses have begun to switch to hybrid systems. The technology has developed and the prices have decreased, so hybrid systems are going to be closer to human life.

conclusion There are 1 billion cars in the world at the moment. It means one out of 6 people own cars. The biggest cause of global warming is increasing carbon dioxide. 20% of carbon dioxide is emitted from cars. According to a chief science professor of the UK government, Sir.John Beddington, in 20 years from now, the world's population is expected to grow to 8.3 billion people, and people will need 30% more fresh water, 40%more food and 50% more energy. In our opinion, people have to try to use alternatives to oil such as the hybrid system, solar energy and so on in order to reduce carbon dioxide and greenhouse gas. Right now, the economy's highest priority is to make money. The economy needs to change its focus to include the environment. Only if people succeed in reducing greenhouse gases and carbon dioxide, can people avoid the effects of global warming. We believe the hybrid car technology is the best choice for the environment so far until solar power technology develops.
