cell phone,our environment

Todays every body which any reasons has mobile phone.None of them does not care about the effect of cell phone's waves.And no one does not think about how much it has damages for environment.Almost every household in America has a minimum of one cellphone and many have used phones laying around not even being used.

The metals and chemicalsthat are used to manufacture these phones are not only toxic but they require energy to make as well.You would not throw away a light bulb for no reason that still has life left in it so why would you simply throw a phone away?

approximately 60000 to 70000 cell phones are sold each day in the United States.Over 110 milion Americans use cell phones.It is estimated that about 1 billion people use cell phones.As the number of cell phones,cell phone towers,and other wireless antennas increase rapidly in industrialized nations, so we should be concern about our health.

Cell phone is in the top of the list of dangerous ,and one of the hazardous pollutant.Mercury and arsenic are in this thing.We just recommend each other utilize cell phone for relaxer in life and easy working,whitout noticing about waves ,and damages for enviroment.

The researches confirm how much it causes cancer.This enormous figure makes for a haunting a mount of toxins that are leeching into the Earth's ground water.

As the number of thrown away used phones increases, so does the negative environmental effects.

The radio frequancy radiation of cell phone has effect on bones,more damages are on childeren.Because their skulls are thinner than adult.So,the radio penetrates their bones easier.

The battery of the cell phone has influence on environment,too.After it expires never take them on trash,send it to it's company for reforming ,again.

If we like to have green environment ,we have to recover new methods for our lifestyle.

DME : Alternative for Cleaner Fuel





Hi everyone,

This time, i would like to share the information on this newly emerging fuel in the market. Dimethyl ether (DME) is regarded as a new alternative for clean energy media. It is described as colourless and clean gas. DME can be produced from various sources such as natural gas, coal, waste from pulp and paper mills, forest products, agricultural by-products and municipal waste.

The potential applications of DME as alternative fuel are listed as follows;

  • DME can be used as a fuel for thermal power generation. During burning process, DME is a fuel that does not produce SOx or particulate with extremely small emission of NOx and CO2. Apart from that, the performance and reliability of DME in power generation is comparable to natural gas. This fact has been approved by General electric, Hitachi and Mitsubishi which utilize DME as fuel in their gas turbines.


  • DME can be used as substitute for diesel as the the cetane rating is high; being 55-60, very high oxygen content, cheaper than diesel, requires very low injection pressure and produce little pollution from combustion process. The DME tests are currently conducted by Volvo and Ford Europe


  • DME can be used as LPG substitute as it has quite similar properties with LPG. So, most of LPG facilities can be utilized for DME.


  • DME can be used as fuel for domestic cooking and heating. DME can be blended with LPG and used without modifications to equipment or distribution pipelines.


  • DME has potential as fuel for fuel cells as it is favourable on the heat balance and low formation of reaction heat.

Hybrid Technology: Key Towards Sustainable Mobility?


Recently, people have been talking a lot about different environmental issues such as the worldwide phenomena of global warming, climate changes, different types of pollutions, flora and fauna conservation, large-scale deforestation activities and sustainable energy. All of these issues, I would personally say that sustainable energy has the largest impact on our daily activities. Since a few years ago, every vehicle owner has been thinking thoroughly about coping with the fuel price hiking in the market. So, I certainly believe that now is the best period for us to look at possible and practical solution. Terms such as hybrid vehicle might pop up in our minds while thinking for the best answer. Oh, even our senior post an article about electric car which is very much related to hybrid technology.



So, what about this hybrid vehicle? Hybrid vehicle refers to vehicle that is powered by more than one power source. Technically, hybrid vehicles can be categorized into two classes; series hybrids and parallel hybrids.



Series hybrids have a gas engine that powers the generator. The generator then charges the batteries and powers the electric motor. The gasoline engine doesn't power the vehicle on its own. The electric motor runs all the time and the gas engine comes on only when needed. This vehicle gets better mileage around town, where the electric motor is doing most of the work.



The parallel kind has a fuel tank for the gas engine and batteries for the electric motor. Both the engine and the electric motor can turn the transmission and power the vehicle. The small gas engine runs the car and the electric motor comes on when needed to boost power. This is typically needed for increasing speed, merging and passing other vehicles.



Lately, various designs of hybrid cars are showing up in the market which indirectly giving a sign of positive commercialization in the future. From small and compact electric cars, evolving to” spacious and sporty sedan car” and then reaching to super sport cars, most of the developed cars are gaining increasing interest from potential buyers worldwide. Furthermore, the main benefits of hybrid vehicles (i.e. able to reduce fuel cost and air pollutant emission) are also strring up the interest.

If you are enthusiastic about cars as well as the future of our environment, or at least you love to look at green engineering, it is worth to look at some of the available design of hybrid concept cars and recently launced hybrid cars in current market.



NISSAN LEAF (NOW ON SALE)






PROTON EMAS CONCEPT CAR ( MALAYSIAN FUTURE CAR =) )






PORSCHE 918 SPYDER HYBRID SUPER CAR (HYBRID SUPER CAR WITH ELECTRIC PLUG-IN)





VOLSWAGEN ELECTRIC MILANO TAXI




TOYOTA 3RD GENERATION OF PRIUS HYBRID





Looking at the pictures above, the hybrid technology is offering promising alternative for building "a car for tomorrow". Car manufacturers are currently applying different technology adaptation on various category of hybrid cars which seems to be very practical. It is indeed a great effort towards greener world as well as sustainable mobility. Even though the technology offered is not yet perfect, I strongly believe that continuous development of advanced hybrid technology would provide impressive efficiency at affordable price, improved equipments and thus able to significantly reduce the dependence on fossil fuel to power our vehicles. Let's hope that the benefits of hybrid vehicles would really outweigh the cost.

ReCYCLEd paper i made my own!









Hey hii guys..I have read Dash's articles on the"small steps to going green"..one of the info she stated out for ideal green life is recycle everything especially PAPERS!

I just want to added info on that particular subject..how are we gonna recycle the papers..this is something that we learnt for subject "Kemahiran Hidup" last time when we are in the primary school. This might be a very simple one and Dr. mams sure not gonna give me a good grades for this but trust me.. none of us still practicing this since we can send them (the papers) to the recycle centers. Hee sorry Dr.mams...I think if i could try this first, then i'll considered everyone could follow my baby steps..so these are what you needs:

1)A Blender or wire whisk
2)Papers of course!
3) Sieve
4)Water
5) Tupperware


Follow these steps..

1) Tear the papers into tiny pieces and soak them in a tupperware of hot water for about 30 minutes. Put a handful of the soaked paper into the blender and mix until mush. Or if using a whisk, beat the mixture until it is a creamy pulp.
2) Put the blended papers in water and started to sieve. You can find a different tool for sieving no matter its round or rectangular. In the sieving process, you can put the sieve into the mixture of blended papers and try to get a thin layer by lifting the sieve up carefully. before that, it is better t ensure that the mixture is not too fluid or else it would be difficult to get layer.
3) After a thin layer has been formed on top of the sieve upside down and put it on some newspapers. the use a cloth to press so that the ayer will go onto the newspaper completely. next, remove the sieve and let the newspaper to dry under the sun or fan. and start from the sieving process and repeat the same steps once more until the mixture is finish.

Simple one..hope you guys can try it ya!

SAVE TREES BY MAKING YOUR OWN RECYCLED PAPER


~~NO plastic BAG day~~~


I came across to a supermarket in Section 13, Shah Alam yesterday morning to buy some stuff..My colleagues and I had plan for a barbecue party last night at their apartment just across The Mines Mall, Serdang. So since I have green engineering exam tomorrow, I've decided not to do the cooking stuff and just throw the money into the problem which I have to buy Pita Bread, Mee Hoon and the mayonnaise as well and the other girls need to buy something else for the party. When I saw the banner in front of the supermarket’s entrance, I just stop and stand right there..I’m wondering how am I suppose to carry all the stuff.. sigh!

As from what I know till now, supermarket always gives their plastic bags FREE!. But then I realize.. why not I just carry all the stuff without a plastic.. after all, its not a wet stuff though..in addition, I can save the EARTH too! But customer will need to pay 10 cent for a plastic bag if they insist on having one. Well, I DO support on the “No plastic Bag Days” but it should be made known to consumers. I saw many others caught by surprise at the cashier’s line.

To those who do not know how these plastic bags is harmful to us..let consider the following shocking facts about plastic shopping bags..

  • plastic bags are made of polyethylene
  • Polyethylene is a petroleum product
  • production contributes to air pollution and energy consumption
  • Four to Five trillion plastic bags are manufactured each year
  • Americans use over 380 billion polyethylene bags per year
  • Americans throw away approximately 100 billion polyethylene bags per year
  • Of those 100 trillion plastic bags, 1% are recycled
  • it takes 1000 years for polyethylene bags to break down
  • as polyethylene breaks down, toxic substances leach into the soil and enter the food chain
  • approximately 1 billion seabirds and mammals die per year by ingesting plastic bags
  • plastic bags are often mistaken as food by marine mammals. 100,000 marine mammals die yearly by eating plastic bags
  • these animals suffer a painful death, the plastic wraps around their intestines or they choke to death
  • plastic bags choke landfills


So guys, we can actually lessen our environmental footprint by minimizing the use of plastic shopping bags. Do bring your own shopping bags every time you go for shopping. if everyone do so, our world will become aBETTER, CLEANER, SAFERplace for all living things including YOU!


this is a good video to watch...5 star one!

RICH people POOR earth??!


Of the many tales and stories of our childhood, there is one which comes to mind immediately as a morality tale with regards to the environment..perhaps even a cautionary one! the heroic and love story of little boy springs to mind..

though cold and wet, the youngster was steadfast through the night in plugging the leak in the dyke with his mere finger..thus saving a town and a nation from certain disaster..can we all afford not to emulate this kid to stem the tide of environmental disaster that will surely befall our POOR earth if we do not act?i've saw so many rich people here in our country, but do they really really care about the environment??well,we can start by relooking the very fundamental and basic aspect of our economy. And what can be more basic than food?shelter? and clothing?its kind of impossible for everyone of us to implement the "green building" concept for our houses..but how about the rich people?the one who own a megastructure buildings,universities, or mall maybe?there is no one single techniques for designing and building a green building. But building that are "GrEeN" often have common design characteristic. Like, preserving natural vagetation, using non toxic or recycled building materials, being readily accessible to public transportation, use of natural lightings and the flexible use of interiors to name a few characteristic. such efforts strongly indicate that we can indeed seek environmental shelter by going green, but can you name me one?i know we have few..but few only lah~

Now as to food..nowadays agriculture has led to severe harm to both the environment and public health. As a production tool, industrialisations of the farm has been a success..BUT the Questions is..is it sustainable??can industrialisation of the farm ensure that future food needs be met? well, no one is suggesting we go back to our current agriculture practices that are clearly unsustainable. And since food is, like shelter, a vital and basic need, the issue of sustainability is driven.

we started off with the love story of the youngster, the very responsible youngster. we end by taking note of an irresponsible one- "like dog cried mountain" (direct malay translation!). most assuredly we are not the crying dog by raising the environmental concern and issues over these past years. they are for real. what is important now is to realize...that beyond the tipping point, there will be little left to save!

Electric Cars: Pros and Cons



The burning of fossil fuels from vehicles will emit a variety of pollutants into the earth's troposphere. Two of the pollutants that are mostly emitted are hydrocarbons and nitric oxide. These pollutants can be harmful to all living life and the environment. Therefore, replacing vehicles having an internal combustion with electric vehicles is seen by some as a solution to this problem.


Comparing both types of vehicle, the electric vehicles is seen to be more environmental friendly and are less polluting compared to the internal combustion engine vehicle. This is because electric vehicles uses whatever electricity is delivered by their electrical grid operator. The source of electricity from the power grid can be drawn from renewable energy such as hydro and wind. Therefore, the electric cars are as clean as the grid. The electric vehicles also reduce greenhouse gas emissions and eliminate petroleum. Thus, it helps to reduce fossil fuel usage despite the fact that electricity is largely generated by fossil fuels. Because even fossil fueled-fired power plants are more efficient than a car's internal combustion engine, the electric car is more energy efficient and produces less overall pollution. Even using electricity from coal, an electric car is 4 percent more efficient than a gasoline burning version of the same car.

Other than that, because all cars required battery replacement eventually, the disposal of lead-acid batteries used in cars with combustion engine is more hazardous to the environment compared to disposing lithium or nickel-based batteries of electric cars. Electric cars also have a lower or no demand for many of the hazardous, polluting fluids used in a conventional car, such as motor oil. Electric vehicles typically have less vibration and noise pollution than a vehicle powered by an internal combustion engine, whether it is at rest or in motion. Therefore, people thought that it is better to replace the internal combustion engine vehicles with the electric vehicles.

Electric vehicles also have some disadvantages. If the internal combustion engine vehicle which is the conventional gasoline-powered vehicles for personal transportation is replaced by the electric vehicle, fuels production and import would switch from petroleum and its products to more coal, natural gas, nuclear, and many others. There would be more mining activities for the extraction of coal and uranium and less reliance on foreign oil. Apart from that, little that people know, electric cars can increase overall emissions of air pollutants particularly in rural areas. Sulfur oxides emissions are increased almost ten-fold by powering a car with electricity instead of gasoline. The same change in fuel also increases total nitric oxide emissions and particulate matters. These pollutants are the primary causes of acid rain.



I think, with some modification to the electric vehicles, it can help to abate the problems. With the advancement of technology nowadays, other alternatives and method of operating vehicles can be developed in order to protect our environment.

So guys, what is your opinion on this matter? Do you think electric vehicles are better than conventional vehicles?
