    I have recently reverted back to petrol powered vehicles. I have had 2 hybrids which neither of them could we keep charged with city driving, we loved them and persevered with them for a few years. I never looked seriously at 100% electric because the number of charging points locally were few and those that are there are placed outside the local TAB. Great if you want to get a bet on while charging. But as with handicapped parking they are generally always occupied by mentally handicapped drivers!

    In theory electric sounds great, but as has been pointed out they are less green to manufacture and also the need to replace the battery packs at around 8 years produce even more pollution in producing the replacement battery packs. There will eventually be a disposal charge to dispose of the batteries, just like tires. I guess it is a similar argument that has been going on over diesel or petrol cars for years. Now the truth is emerging that diesel is not as clean as had been suggested. In fact some manufacturers have indicated they will stop producing them soon.

    I would imagine that the Gov’t of the day will tax electric vehicles as the revenue from petrol sales will drop and the tax will have to come from somewhere. With an aging population there is a drop in the tax take through fewer workers paying income tax as well, so logically the user will have to pay, as we do now.

    I don’t think I have seen nuclear energy mentioned as a source of power. I raise it as despite many Kiwis believing we are nuclear free there is a nuclear facility sitting in Gracefield/ Lower Hutt chugging away. We may have a clean green image but this is far from the truth if you bother to look.

    For me the end of the road for petrol cars will be when I fail my driving retest, but then I will go on polluting with public transport.

    Regardless of the colour of your politics as long as humans walk this Earth there will be pollution of some sort or another, ” beam me up Scotty” isn’t here yet and there would be some pollution associated with this as well. As long as we make anything or consume anything we create pollution, just sitting on the throne we produce pollution! Simply ending petrol cars, or for that matter stopping plastic shopping bags we still pollute by generating the energy required to make whatever or cook whatever. No matter what we as humans are doing we are causing some pollution somewhere along the chain to the end user, us.

     

    I’m not sure if food for thought produces any pollution, but give it a try.

    I remember being told that the human being is the only animal that craps in his own nest.

    Brother, have we what.

    Eventually we will have to clean up our own mess, I hope we collectively don’t leave it too late. Mind you, too late and I won’t be here to worry about it.

    CNG was going to be the pot of gold for nZ at one stage! We were both using HQ Holdens on CNG as we were doing a high milage at the time, however they went the way of all older cars and went to Holden Heaven and now we only run a fuel efficient Japanese import. Thing is the Govt at the time was “Pushing” cars to this fuel and it was going to save NZ millions. How Lon g did they last? I’m interested to know how efficient the Hybrid cars are if using ONLY petrol.

    May I correct you Bryan? Only Fords go to heaven. Holdens go to that other place where there are flames.  🙂

    But on a serious note, doug, you raise a good point. Should we consider nuclear energy generation. While we are led to believe that nuclear energy is bad the science demonstrates that it is the cleanest of all current methods of creating electricity.

    But perhaps not very wise in such an earthquake prone country,Halycon. But we do need to come up with an alternative of some kind – perhaps solar cars similar to the one which a few years ago drove around the world.

     

    vchttps://www.wired.com/2008/12/around-the-worl-2/

     

    “Louis Palmer has driven 32,000 miles through 38 countries in 17 months to become the first person to circumnavigate the globe in a solar car.
    <p class=”paywall”>The 36-year-old Swiss school teacher pulled up to the U.N. climate talks in Poznan, Poland, where representatives from almost 200 countries hope to hammer out a new treaty to address climate change. Palmer didn’t burn any petroleum during his ’round the world drive, and says the car “ran like a Swiss watch,” proving solar is a viable transportation technology.”</p>
     

    Or there might be all kinds of other ideas which have yet to be invented.

    No body has answered my question as to the efficacy of running a hybrid car running on it’s own generator. I do doubt it is more efficient but I’m interested to know?

    I googled your question Bryan and came up with the following:

    “An idea that’s frequently asked is why can’t an electric car charge itself while driving? For example adding a generator to the wheels, or a wind turbine to the top of the car? Or maybe solar panels on the roof. It’s an attractive idea isn’t it, infinite range just by capturing energy while the car is moving? Unfortunately there are some pesky facts from physics that get in the way.
    All gasoline vehicles have a generator (the alternator) that recharges the starter battery. The thinking must be that electric cars must be able to do the same. The problem is that a generator attached to the wheels slows the car down, converting the vehicle’s inertia into electricity. That’s how Regenerative Braking works. The electric motor is engaged with the wheels in a mode that uses the motor as a generator, diverting some of the inertia from the vehicle, slowing the vehicle down, while at the same time generating some electricity that’s funneled into the battery pack.

    Enough energy is converted through regenerative braking that, for some cars, the car can be stopped solely with regen, and not require the mechanical brakes. In the right conditions, one can start at the top of a mountain, drive 20 miles downhill and gain 4 miles of range.

    There’s nothing magical about this, because it works within the parameters developed by Physics researchers over the last few hundred years. The Law of Conservation of Energy applies to electric vehicles. A generator attached to the wheels diverts the inertia energy, causing a decrease in inertia, resulting in lower speed, while converting inertia into electricity. A little wind turbine attached to the car degrades its aerodynamics making the car less efficient, and also diverts inertia to generate electricity with the effects already stated.

    If your energy conversion device were 100% efficient you could divert the entire inertia to generate electricity, and in the meantime the car would stop moving. That result isn’t exactly what’s desired, and the energy gained that way is only enough to get the vehicle back to speed, not to move it for a significant distance.

    Another description of this problem is :- Perpetual Motion. According to Physics it’s impossible to create a Perpetual Motion device – that is, a device that’s active indefinitely.”

    If the majority of people charge their cars overnight when they are home the drain on the national grid will be manageable.

    If the country invests in more solar generation on homes and recharge stations the drain will be even less.

    So far NZ has managed very well with renewable energy so when it comes to comparing efficiencies NZ is way ahead compared to other countries that generate power from coal or oil. Any article comparing the two must be checked to see where the source figures are coming from and what the breakdown is. Coal and oil V wind, hydro, solar, nucleur.

    Comparisons in the future will also be dependent on the cost of battery production. This is relatively high at the moment but with all the work being done on batteries this could fall dramatically in the future, depending on which technology wins out.

    Cheers 🙂

    Here is an interest article for those that are interested.

    https://www.ucsusa.org/clean-vehicles/electric-vehicles/life-cycle-ev-emissions#.Wv0G0_luaUl

    This was of interest.

    These differences in CO2 production change as soon as the cars are driven. EVs are powered by electricity, which is generally a cleaner energy source than gasoline. Battery electric cars make up for their higher manufacturing emissions within eighteen months of driving—shorter range models can offset the extra emissions within 6 months—and continue to outperform gasoline cars until the end of their lives.

    By the end of their lives, gas-powered cars spew out almost twice as much global warming pollution than the equivalent electric car. Disposing of both types of vehicles (excluding reusing or recycling their batteries) produces less than a ton each.

    Cheers 🙂

    When it comes to comparing how the electricity is produced and the effects electric cars would have in those counties then this is a good website to check out.
