A Compressed Natural Gas Fuel Q&A
A COMPRESSED NATURAL GAS (CNG) FUEL Q & A
By guest contributor Ee Lynn
Here are some questions asked of the Green Living coordinator via e-mail and at outreach events:
Q: WOULD A CNG CONVERSION/RETROFIT REDUCE THE ENVIRONMENTAL IMPACT OF DRIVING MY CAR?
It definitely would! CNG or compressed natural gas is a domestically available, economical, clean-burning, alternative fuel source for vehicles. In addition, natural gas does not contaminate lakes, rivers, or groundwater as petroleum fuels do, because it quickly dissipates into the atmosphere if a leak or spill occurs.
The U.S. Environmental Protection Agency calculated the potential benefits of CNG versus petroleum based on the inherently cleaner-burning characteristics of natural gas:
• Reduces carbon monoxide emissions by 90%-97%
• Reduces carbon dioxide emissions by 25%
• Reduces nitrogen oxide emissions by 35%-60%
• Potentially reduces non-methane hydrocarbon emissions by 50%-75%
• Emits fewer toxic and carcinogenic pollutants
• Emits little or no particulate matter
• Eliminates evaporative emissions
The U.S. Environmental Protection Agency has called the natural gas Honda Civic GX the cleanest internal-combustion vehicle on Earth.
Q: I READ OF THE RECENT EXPLOSION OF A CNG-POWERED VEHICLE (A.K.A. NGV). IS NATURAL GAS SAFE TO USE AS FUEL?
The authorities are still trying to determine the cause of the explosion of the NGV reported in the newspapers. However, all professional bodies including the (U.S.) Union of Concerned Scientists and Environmental Protection Agency are of the opinion that natural gas is a much safer fuel than petroleum.
Natural gas is lighter than air. This means that it will not puddle (like petroleum) or sink to the ground like propane, which is heavier than air. Instead, natural gas will rise and dissipate in the atmosphere. Natural gas also has a higher ignition temperature. This means that it is much harder to ignite. Also, the US Dept of the Environment reports that the storage systems used for compressed natural gas are infinitely stronger that the petroleum tanks found on cars and trucks today.
Q: WHAT FACTORS SHOULD I TAKE INTO CONSIDERATION BEFORE MAKING THE DECISION TO RETROFIT/CONVERT MY CAR TO RUN ON CNG?
Although some environmentalists have expressed concern that natural gas is also a fossil fuel and reliance on it may be ‘prolonging the problem’ of finding an alternative to fossil fuels, and that increased use of natural gas will require infrastructure investments that have a high environmental impact, the Union of Concerned Scientists believes that experience with gas-based fuels and their transportation/transmission infrastructure will facilitate a transition to future alternative fuel systems, such as hydrogen fuel. At the moment, natural gas is the most economical, widely accessible and cleanest-burning fuel for vehicles available.
As the writer of this column has been using a vehicle retrofitted to run on CNG since October 2008, her advice to those contemplating a CNG vehicle retrofit/conversion is as follows:
- Utilise only the services of licensed NGV installers and repair/service workshops.
- Ensure that there are at least 2-3 NGV stations within 3km of your home and/or workplace or along the route you regularly use. Refuel during non-peak hours so you will have a shorter queuing/waiting period.
- Recognise the fact that there may be a slight reduction in your vehicle’s torque/power, especially when going uphill or carrying a heavier load than usual.
- Sign up with online NGV locator forums to find out about the availability of NGV stations outside of the Klang Valley and to receive news on the opening/closure of NGV stations.
- Find out about, and adhere to, the JPJ and Puspakom certification and endorsement procedures.

Let's make sure the trees live!
Living in an apartment means I have no where to efficiently utilise my precious compost. Whether fortunately or unfortunately, right in our back yard almost, there's a nastily turfed up piece of land that's been very recently replanted with trees. Hubbie and I have been very cross to find out that that land is actually forest reserve land, but that's another story. After all the damage that's done to it, the land is parched and the trees don't seem to be doing too well.
Today, armed with a spade, hat, and a curious 2 year old, I finally took my tub of compost out and spread it around two very scraggly trees.
Which made me think. All the exercise I hear about tree planting is all great. In fact, I've also been involved in it myself. However, I don't know about what happens to the tree after that. Really, did it survive? Did it dry out? Is it a glorious tree now? I have no idea.
Now, back to the trees right here in my 'back yard'. They weren't planted by me. But I wanna try and help them flourish.
Kills six birds with one stone. i) eliminate kitchen waste ii) get rid of compost iii) help trees grow iv) contribute to increasing comfort in my home area v) teach kid about nature vi) get a bit of good ol' exercise. Hmm, one more and I'm the like the gallant tailor. Ha, I wish.
There are at least another 20 trees more to go. Two down. Second tub ready in a week.
Nice.

Product Review: Bio-Home Dishwash Liquid
Product Name: Bio-Home Dishwash Liquid (500 ml)
Manufacturer: Lam Soon Edible Oils Sdn Bhd
Price: RM6.49 from Cold Storage, RM5.50 from Isetan Supermarket
Rating: 4 ½ stars out of 5
(By Guest Contributor Ee Lynn)
To me, looking for the biodegradable, eco-friendly dishwashing liquid that is ‘just right’ is an endeavour highly similar to Goldilocks’ attempt to find the right bed and porridge and what-have-you. ‘Good Maid Bio’ is supposed to be 100% plant based, but I am not convinced, on account of its surprisingly low cost, its strong cloying fragrance and its garish neon colours. Fruit and veggie waste enzyme is too watery and too stinky for me, and I am not persuaded by the science, or lack thereof, of homemade enzymes. Ecover and Ivory are both too watery and too expensive, and I refuse to pay RM12.99 or thereabouts to have a bottle of runny soapy water flown to me from halfway across the planet just so my kitchen runoffs do not kill toads and little fishes.
Imagine my surprise and delight then, when I discovered a locally manufactured brand of eco-friendly dishwashing liquid that is affordable, easy to use, and of just the right consistency. Resembling a bottle of handwash, each 500 ml bottle of Bio-Home Dishwash Liquid comes with a handy pump dispenser, thus eliminating the need to tip the bottle over each time you need a squirt of washing-up liquid.
I immediately liked the fact that it is produced locally, thus cutting down on the fuel miles each bottle had to travel. I also like its packaging, which makes it easy to use and which incidentally reduces wastage, because you are less likely to pour too much out when using a pump dispenser. I like the fact that it is free of dyes, because dyes are wasteful and have no real purpose except to make a product look appealing. I simply love its lemongrass and green tea scent, which is a welcome change from the conventional lemon-lime scent used in washing-up liquids. I like the fact that it is concentrated enough, so I am not just paying for a bottle of water with a dash of soap in it (I have been using my first bottle for over a month now, and despite the fact that I am a cleaning freak, I have not even used a quarter of a bottle).
But does it work? The label says that the product is Biodegradable, Eco-Friendly, Easy Rinse and uses Natural Ingredients. Apparently it is also made entirely of plant-based biodegradable surfactants, and carries the Singapore Green Label. The label further proclaims that it does not contain any phosphates, SLS (Sodium Laureth Sulphanate), synthetic dyes, caustic agents or animal-based ingredients, which is good enough for most of us.
Fortunately, this handy little bottle of washing-up liquid really does live up to its promise, in my book. I poured some of the leftover liquid (after washing up with it) on my Epipremnum pinnatum to see if they would survive. The plants thrived. I left a dab on my wrist to see if it would affect my already sensitive skin. It didn’t. I felt nothing and forgot all about it. I cleaned the sink with a little of the liquid and rinsed everything off using only one mug of water, so it really is easy-rinse. I used it for more than just doing the dishes with, to see if it would hold up against scrutiny, and it did. I rubbed some, full-strength, on a coffee stain and a grease stain on my t-shirts to see if it could clean and degrease effectively. It did. I added some to my biodegradable soap powder to clean the bathroom with, and everything came out spotless and smelling faintly of lemongrass. I diluted a squirt of it in a bottle of water and used it for general cleaning, and it managed to pick up dirt and remove spots and stains without leaving a soapy residue. I collected some of the soapy water in a basin while doing the washing-up and soaked some empty glass coffee jars in it to remove the labels and coffee residue. The labels and residue came off easily with a little scrubbing the next day (note that I wasn’t using Bio-Home full strength, but as leftover from washing up). I squirted a little of the dishwashing liquid on the washcloths and scrubbed the cloths hard to clean, degrease and deodorise them, and it worked a treat, too.
If I have any complaints about the Bio-Home Dishwash Liquid at all, it is that 500 ml doesn’t go very far and the manufacturer should produce larger bottles to refill the original one with, to cut down on packaging and waste. It would also help if the manufacturer were to include a full list of ingredients on the label or at least the website, to allow consumers to make an informed choice in order that we do not fall victims to greenwashing.
All things considered, I would rate the Bio-Home Dishwashing Liquid 4 ½ stars out of 5.

Car that runs on AIR? *drool*
*drool drool drool*....
How would you react to someone who tried to sell you a car that runs on fresh air? Perhaps you would think he was peddling a potentially planet-saving technology. More likely you would dismiss him as a conman or a fantasist. Yet that is precisely the pitch being made by French auto engineer Guy Negre, a good-humoured man in his mid-60s who claims to have developed a car powered by compressed air: one that produces a fraction of the carbon emissions of a standard engine, reaches speeds of 30mph-plus, that can travel 65 miles on a one-minute recharge and, best of all, costs from just over £3,000.
Negre is quick to point out the drawbacks of existing eco-car technology. "Hybrids are only marginally less polluting than the most efficient combustion engines," he says. "Hydrogen power is expensive and impractical. Fuel cells are expensive and unproven and electric cars are reliant on expensive, unreliable battery technology."
Given the number of false green-auto dawns, you might wonder why air-powered cars should be any different. While Negre's air cars have similar carbon emissions to electric cars (it all depends how the electricity to power the pumps that fill their air tanks is generated), he argues that air-power is a superior technology. "Compared to electric cars, air-powered cars cost a fraction of the price to buy, they don't need expensive batteries to be replaced every five years or so and crucially they take only a fraction of the time to recharge."
Negre previously designed racing engines for Renault and has devoted the last 13 years to developing compressed air technology at his factory in Carros, outside Nice, in southern France. He believes air power has a real chance of putting a rocket up the $2tn-a-year global auto industry, radically improving the quality of urban life and making a serious dent in global carbon emissions in the process.
I confess I was so sceptical that I reserved judgment until I had driven one of his cars. On the day I visited the factory, most of the cars were at Schipol airport in Amsterdam, where from next month they are being trialled as replacements for the huge fleet of electric service vehicles operated by Air France KLM. So the version I drove was an early prototype, a three-wheeler with no bodywork, steered by a joystick.
OK, it didn't deliver the smoothly upholstered power so beloved by conventional car enthusiasts. And it possessed all the glamour of a souped-up lawnmower. But it worked, easily reaching speeds above 25mph in the limited space of the factory car park, which doubles as a test track.
In full-scale production, air-powered vehicles will range from three-wheeled buggies to a four-wheeled, five-door family saloon. Although the number of models on offer now is limited for cost reasons, they could eventually include vans, buses, taxis and boats.
The cars are made of fibreglass, which is lighter and 10 times stronger than steel, claims Negre. The compressed air is stored at high pressure in shatter-proof thermoplastic tanks surrounded by a carbon-fibre shell. (The same tanks used to contain the fuel in gas-powered buses.) The air is released through pistons in the engine, which drive the wheels. Unlike conventional internal combustion engines, air-powered engines run very cold and thick ice quickly forms on the engine. This means that the only feature that comes for free in the air car will be air-conditioning.
Each car has an onboard pump that can refill the tank overnight. But Negre has also developed a high-pressure air pump - imagine a heavy-duty version of the tyre pumps found on a garage forecourt - that can fill the tanks in less than a minute. These could be powered by clean electricity - hydro, wind or solar - making the air car completely pollution-free. Even if carbon-generated electricity is used, CO2 emissions are still only 10% of a petrol engine's, claims Negre.
That's great for urban driving where journeys are typically a few miles. For longer journeys there's a hybrid, battery-assisted version, which Negre claims can reach 100mph and travel 900 miles on one gallon of petrol.
Clearly the idea is being taken seriously by KLM. Independent energyexperts are also cautiously optimistic. "I've looked at this technology and it can work," says Ulf Bossel, a sustainable energy consultant and organiser of the European Fuel Cell Forum. "It looks good over 50km or so. I see no reason why this shouldn't be a successful form of urban transport in the near future."
But perhaps the most credible endorsement of air power comes from a £30m deal the makers recently signed with Indian car giant Tata to license the technology in Asia for use in the ultra-cheap Nano. Negre has also signed deals to manufacture the car in the US, Latin America, and several European countries, but none as yet in the UK. However, he says he is close to sealing an agreement that could see air cars on sale in the UK within three years. But if cars running on fresh air fulfil their promise, why stop there? With just a few alterations, Negre claims a hybrid version of his new engine could even be used to power aircraft.

Environmentally Responsible Pet Ownership
ENVIRONMENTALLY RESPONSIBLE PET OWNERSHIP
Some environmentalists claim that the best way to be an environmentally-friendly pet owner is to have no pets at all, because pets consume so much water and food and generate so much more disposable packaging and waste that it will put a strain on the Planet. However, most people would agree that animals bring us joy and happiness and improve our physical and mental health. Here are ways to ensure that you and your beloved animal companion do your part for the environment:
1. Adopt only animals that have been selectively bred to live with humans and depend on humans for care and companionship, such as dogs, cats and rabbits. Do not support the wildlife trade by purchasing exotic animals such as sugar gliders, raccoons, green iguanas and Indian star tortoises.
2. Opt to adopt – Our animal shelters and pounds are full of animals in need of good homes. By adopting from shelters and pounds, you are not only preventing the needless killing of healthy animals, you are playing your part in reducing the numbers of unwanted animals that may end up abandoned. Animal breeders contribute to the problems of pet abandonment and stray overpopulation by bringing more animals into the world when there is already an existing shortage of natural resources and fresh water.
3. Spay or neuter your pet – Pet overpopulation creates social and environmental problems such as noise and faecal pollution. Hungry stray animals scavenge in landfills and waste bins, chase people in their search for food, and contract and transmit diseases. The easiest and best way to end the plight of stray animals is by ensuring that your pet is neutered before he or she has had the chance to reproduce. You will save yourself the agony of trying to find good homes for the offspring, and feeding and caring for more animals than you could afford to.
4. Clean up after your pet – Letting your pet eliminate waste in public areas is antisocial, and could lead to groundwater pollution. There are several eco-friendly ways of disposing of pet waste. Flushing it down the toilet will ensure that your pet’s waste ends up in the sewage treatment plant. Try getting a pet waste composter where available. These bins are buried halfway into the ground and then filled with pet waste. From time to time, digester powder and water or activated charcoal is added to help the pet waste break down safely. Burying pet waste in ornamental garden beds (not in your compost bin or vegetable patch!) is an acceptable way of dealing with pet waste. Just ensure that it is away from water sources (lakes, streams, wells, irrigation canals). Dig a hole between 6 inches and 1 foot deep, fill it with pet waste and cover it thoroughly with soil to prevent flies and other disease vectors from being attracted to it. It is advisable
to bury pet waste a little distance apart each time to allow time and space for decomposition. Putting too much pet waste together in a hole may result in the formation of leachate or may attract flies and rodents. You can bury pet waste together with newspaper scraps, biodegradable litter, garden waste, lawn trimmings, sand and/or vegetable waste.
5. Go organic – If you could afford it, make or buy organic food, treats and/or toys for your pets. Organic products are better for the environment because they are produced without chemical fertilisers, pesticides and herbicides, and thus are less likely to pollute water, soil and air or disrupt the ecosystem. In addition, organic products are better for your beloved companion because they contain no artificial colouring, flavouring, phthalates, preservatives or animal by-products from diseased animals.
6. Reuse old items and repurpose them into pet toys – Who says your pet needs plastic knick-knacks to be happy? Cut old t-shirts up and braid or knot them into tug toys, or sew 2 pieces together and stuff them with t-shirt scraps to make cushions and rugs for your pampered furry one. Old shuttlecocks, tennis balls, wine bottle corks, cardboard toilet roll tubes and small (but secure!) containers make great cat toys. Unwanted cardboard boxes of all sizes make great hideaways and cubby holes for cats, puppies and other small animal companions.
7. Use natural cleaning products – Your pet’s nose and paws may be more sensitive than the average human's nose or hands, so make sure you do your pet and the environment a favour by using only natural cleaning agents. Fruit or veggie waste enzyme can remove dirt, and lemon juice helps to deodorise ‘accident’ spots and deter pets from using the same spot as a toilet again. Lemon and orange peel work well as a chemical-free deterrent to stop your cat from climbing up the kitchen counter or scratching the furniture. A drop of multipurpose organic/biodegradable cleaning solution in a pail of water is good enough for cleaning the floor, gutters and kennels/cages. Choose biodegradable soaps and shampoos with natural ingredients.
8. A Friend Is For Life – A companion animal is a long term commitment, and he or she will depend on you for food, shelter, medical care and companionship for his or her entire life, so never treat your pet as a fad or an accessory. We depend on them for love, security and companionship – at the very least, we owe them a better life.
How Much CO2 Do Internet Searches Generate?
HOW MUCH CO2 DO INTERNET SEARCHES GENERATE?
Many of you would have heard a public service announcement on radio claiming that “performing two Google searches from a desktop computer can generate about the same amount of carbon dioxide as boiling a kettle of water” or about 7 grams of CO2 per second.
IS THIS TRUE?
We are happy to report, upon researching online, that the above does not refer to a one-hit Google search taking less than a second to complete, which Google says produces only about 0.2g of CO2.
It is only when a Google or other Internet search engine search takes several attempts to find the object being sought, and which may last for several minutes, that the CO2 emission rises. Various experts put forward carbon emission estimates for such a search of 1g-10g depending on the time involved and the equipment used.
WHAT HAPPENS WHEN YOU CLICK ‘SEARCH’
“Google operates huge data centres around the world that consume a great deal of power,” said Alex Wissner-Gross, a Harvard University physicist whose research on the environmental impact of computing is due out soon. “A Google search has a definite environmental impact.”
A recent report by Gartner, the industry analysts, said the global IT industry generated as much greenhouse gas as the world’s airlines - about 2% of global CO2 emissions. “Data centres are among the most energy-intensive facilities imaginable,” said Evan Mills, a scientist at the Lawrence Berkeley National Laboratory in California. Banks of servers storing billions of web pages require power.
Though Google says it is in the forefront of green computing, its search engine generates high levels of CO2 because of the way it operates. When you type in a Google search for, say, “energy saving tips”, your request doesn’t go to just one server. It goes to several competing against each other.
It may even be sent to servers thousands of miles apart. Google’s infrastructure sends you data from whichever produces the answer fastest. The system minimises delays but raises energy consumption. Google has servers in the US, Europe, Japan and China.
CO2 EMISSIONS CAUSED BY INTERNET USE
Researchers have also calculated the CO2 emissions caused by individual use of the internet. Alex Wissner-Gross’ research indicates that viewing a simple web page generates about 0.02g of CO2 per second. This rises tenfold to about 0.2g of CO2 a second when viewing a website with complex images, animations or videos.
A separate estimate from John Buckley, managing director of carbonfootprint.com, a British environmental consultancy, puts the CO2 emissions of a Google search at between 1g and 10g, depending on whether you have to start your PC or not. Simply running a PC generates between 40g and 80g per hour, he says. Chris Goodall, author of “Ten Technologies to Save the Planet”, estimates the carbon emissions of a Google search at 7g to 10g (assuming 15 minutes’ computer use).
Nicholas Carr, author of “The Big Switch, Rewiring the World”, has calculated that maintaining a character (known as an avatar) in the ‘Second Life’ virtual reality game, requires 1,752 kilowatt hours of electricity per year.
Though energy consumption by computers is growing - and the rate of growth is increasing - Newcombe argues that what matters most is the type of usage.
If your internet use is in place of more energy-intensive activities, such as driving your car to the shops, that’s good. But if it is adding activities and energy consumption that would not otherwise happen, that may pose problems.
GREEN LIVING RECOMMENDS:
1. Limit the amount of time you spend surfing the Internet and viewing unnecessary websites such as entertainment websites or playing online games.
2. Do not generate, forward or transmit spam. Use a spam filter to reduce the amount of time you spend online deleting unwanted mail. BCC (Blind Carbon Copy) the names and e-mail addresses of your e-mail recipients to reduce the chances of their names being ‘harvested’ from your e-mails by spammers.
3. Use the Internet as a substitute for activities that would otherwise use more fuel, energy and resources, such as paying your bills at a bank, going shopping, purchasing newspapers and magazines or sending snail-mail.
4. Do not conduct unnecessary Google searches, such as looking up your own name or your friends’ names!
5. If you have a blog, social networking page or Facebook page, reduce the number of applications and animations you have. Keep it basic. If it’s taking too much time to load your page, chances are, it’s using up more energy and releasing more CO2 than it should.
