HYBRID CAR
Session 17
LIGHT AND SOLAR
ENERGY
Scientific experiment
Please find your partners and accomplish the activities
cooperatively.
Team Up
Story TimeFrom my outward appearance I look like any other car, but I’m much
more than that. My body is that of a standard vehicle, but underneath
the hood, I am a completely different machine. I’m a hybrid vehicle. At
my core, I have two hearts, an electric motor and a traditional internal-
combustion engine. I run off both gas and electricity.
It may sound very complicated, but don’t worry, the two engines inside
of me can cooperate automatically. For example, I usually use my
electric motor, but if I suddenly start driving up a steep hill, I can switch
over to my gas-powered engine to provide the extra force necessary to
climb up the hill. In this way, I can work to conserve my fuel for
necessary situations.
Story Time
I have the ability to recycle energy. When I slow down by
braking, I can convert the force of the wheels turning into
back into storable energy that can be used to recharge my
electric battery.
Daily Application
Hybrid vehicles are able to regenerate their batteries while using their
gas-powered engines, or through the disposal of waste such as
exhaust. Hybrid vehicles use this system to not only increase efficiency,
but to save energy as well. The basic concept of a hybrid system is to
convert energy in the most efficient way possible. Waste heat boilers,
located inside waste incinerator plants, are another example. Waste
incinerators can help to solve some of our pollution problems, and
additionally can recycle heat energy.
Brainstorming
What are the pros and cons of using either a hybrid
system or a single-source system?
