The
plants are used for various ways. I search how to use the plants as a resource.
For example, they are used for medicine, food, and fuel. I am especially
interested in fuel, so I searched fuel as the main point.
the cycle of bio fuels
The
fuels that are called “bio fuels” are produced by plants. The materials of them
are, for instance, corn, bamboo, sugarcane and so on. The bio fuels are divided
into two types. First type is called bio ethanol. This is mixed in gasoline,
and used in various places today. Second type is bio diesel fuels. This is used
almost only them and utilized in a city bus etc now.
The merits of “bio
fuels” are it thought that it is not increase CO2 to burn them because their
materials are plants, so they can do photosynthesis which they absorb CO2 in atmosphere
and emit O2 to atmosphere. Frankly speaking, “bio fuels” are recyclable energy.
The reason of above, a lot of nations are researching bio fuels and going ahead
to introduce using them.
The demerits of “bio
fuels” are that when we make them we have to use so many plants that parts are
food. For example, the corn is eaten by pig and human beings and so on. So, the
price of that part of foods will rise. Especially, in Japan, that is very big
problem because grain is a little to provide ourselves. As a result, in the
latter of 2007, Japanese economy was influenced by increasing import grain’s
price. So, to use grain, when we make foods, became a little hard. We should
not use the grain that can eat, and we should use the grain that cannot eat.
Also “bio fuels” cost more money than gasoline now. So, researchers have to
study cost cut ways.
There is worrying
point. I explained the merits of the cycle of CO2 and O2. Some researcher said
that this is uncertain.
Recently, the
waterweed is much remarkable resource of “bio fuels”. This way cost less money than
ordinary ways. It needs to make a lot of waterweed under bad environment that
there are other bacteria. This is main problem. Now, venture business succeeded
in stable to make the waterweed. So, we expect that this will lead mass produce
the waterweed.
making waterweed
Finally, I think “bio fuels”
need to our future because it is said that oils will dry up in the future. I expect
to researchers will find out and make very good ways.
