    I'm thinking of going up there just to run him over a few times though as I could do with some traction compound on the tyres

Not to mention depleting the natural resources in doing so..

    An upgrade in the air/fuel management or systems for example can make great improvements to older vehicles in both fuel economy and emission. A car sustained with some parts replacement and upgrade and kept running for 20 years sounds more environmentally friendly to me as compared to one who would have say change 7 different new cars in that span of time.

    Just another look at the environmental issue in relations to cars.
    Why -
    1. Throw away society that likes new toys.......
    2. Jobs (US car manufacturing industry had to be bailed out and still some of them have sunk)....
    3. Who's supplying refurbished cars that the gov accepts as equivalent to new?

    Anyway what happened to the Air Car that Tata were suppose to produce?

    alamak, easy lar, sit around whole day, eat lots of junk food & fast food, drink lots of soft drinks (btw, why is it call soft ah?). than u will soon have ur very own a tyre. easy to up size some more.

    Haha I happen to like old aunties, being an old uncle myself!

    It's called "soft drink" because it didn't have alcohol in it or liquor.

    Anyway so is this thread about fuel efficient cars or hybrid cars? And as an oil loving nation - why would we want to have hybrid cars?

    Not quite true. LPG powered busses have been around for over a decade. We've had them here in Perth for years now. Nor do all trains source their energy from natural gas stations, a large proportion of the global train population are diesel and in parts of Africa and South America steam still runs some working trains.

    It just does not make too much sense other than a reduction of direct air pollution of roads and cities.
    Are we being told the truth in this whole hybrid electrical car issue?
    Incorrect! The energy losses in a fuel engine are quite high. Firstly few petrol engines are more effeceint than about 15-20% in the real world and that includes the use of turbo and super chargers, fuel injection etc. The thermodynamic limit of effeceincy is 37% for a steel engine.

    Diesel on the other hand has a typical effeceincy of around 45% for engines produced in the past 15 years or so and the next generation of engines should be around 55% effecient. The theoretical maximum effeceincy for diesel is 75%, double that of a petrol driven engine of the same capacity. For a given kW rating a diesel will use approx 40% less fuel.

    Electric motors on the other hand can be made with very high effeceincy levels but the exact effeceincy of the engines in cars I am not sure about.

    You have also neglected to factor in such things as transmission and gearbox losses and exhaust system losses. I can state with 100% certainty that on a turbocharged petrol engine the fitting of a muffler can reduce power by over 12% and that has a huge bearing on the amount of fuel used and overall system effeceincy.

    When did what happen haha? Time for PM methinks...

    Why we need hybrids. Technically Singapore doesn't need hybrid cars, it could get away with the majority of drivers using purely electric cars. Oil is after all a finite resource and sooner or later we will run out of it.

    Agree however Sg doesn't appear to encourage hybrid cars, let alone electric cars. The range of hybrid cars in Sg are few and expensive and sadly not that good. Probably due to lack of demand and the "cool" factor is not that high. Some dudes have gone thru the expense of converting their cars to CNG. But CNG refilling stations are few and far between.

    Last convention, gahment made a sweeping statement insinuating they could reduce their carbon emissions by a lot more if countries played ball. If gaht really interested, they could set a precedent and go for a zero emission country - as per LA in the 90s. But I guess it is either used as bargaining power, or Sg's economies have a heavy reliance on refining and using oil. Anyway after oil, they will turn to liquifying coal as a fuel source. In fact with the price per barrel of oil, liquifying coal is becoming more economical to do.

    As for H2 cars, anyone heard of any future plans to install H2 refilling stations?

    Of course living in the land of ancientness I don't always know what's going on up north a bit in Singapore. However you're quite right the current crop of hybrids are pretty pathetic and very overpriced for what you don't get. LPG (Liquified Petrolium Gas) is what's used down here by all the taxis, busses in Perth and quite a lot of private motorists. Most service stations (petrol stations) have LPG in the main cities but it's harder to find out in the country. Dual fuel vehicles are also popular and the most fuel effeceint are the diesel / LPG systems which while expensive (about 5K AUD) to install give a 20% or so rise in fuel economy.

    Hydrogen is as far as I know only currently available in California, though I may be wrong.

    I reckon they'll use shale before coal as a liquifaction to oil source as the process for producing oil from shale is a mature technology that's been around for at least 73 years as the Germans were using it during WW-II.

    Environmental oxymoron. Hydrogen molecules still requires large amount of cheap energy sources (fossil fuels primarily) to be separated through electrolysis or thermolysis as after all hydrogen is a non-natural occurring element on Earth.

    Alamak - what science class have you been going to? Hydrogen is number one on my periodic table and is the most naturally occurring of elements. Think wat cha mean is that H2 gas is highly unstable and does not occur so naturally. The obvious is to split H2O and that requires energy. Although there are biological methods to also produce H2. Anyway let's talk about the cars.

    Any sexy looking hybrids around?

    That's exactly how they do make Hydrogen by the electrolysis of water, a technique that's used in mass production of Hydrogen gas.

    Sexy looking Hybrids, erm no unless you think a Toyota Corolla or Camry is sexy...

    Let's not argue about semantics. Pure hydrogen element is exactly what I was referring to.

    Biofuel seems to be a viable alternative though especially with regards to algae fuel with flight trials having been conducted on commercial airliner.

    I stand by my original statement, contrary to what your chemistry class had taught you, naturally occurring pure hydrogen element is hardly available on planet Earth.

In fact, when the Diesel engine was first designed, it was not built to burn fossil fuels, but designed to burn a vegetable oil. Fossil fuels were only used as the dominant fuel because (at the time) they were plentiful and cheap.
    Do you have actual facts to support your claims? Are there actual figures to prove that the production pollution is more then a regular car and the hybrid engines do not overall reduce the pollution that it contributes to the earth?
