    Yes. Much of the current Queensland coal production owes its existence to shotholes drilled for seismic exploration for oil in the 1960s - supplemented by water bores.

    There was a coal mine here, on my next door neighbour's place - shut down after NSWGR went diesel in the 1960s, or probably before that when the local passenger service (discontinued in 1973) went from steam to rail motor, I think, 1949.

    My mate was working for the exploration company quite recently, from about 2005 to 2012. Their search was specifically for commercial deposits of coal.

    There were lots of small mines in Qld. that supplied coal to the railways particularly on the Ipswich-Rosewood field. Most closed down beginning with the bulk closure of branch lines to when the railways went diesel, the council power station that supplied the tramways closed, and the various gasworks went to natural and reformed petroleum gases (refinery waste). Was not NSW the last rail system in Oz to use steam locos?

    There was a walk-in coal mine near Katoomba, long closed.
    And the funicular is still serving a very useful purpose of transporting tourists down to where the mine was.

    I’m pretty sure the dinosaurs died out when they stopped gathering food and started having meetings to discuss gathering food

    A bookshop is one of the only pieces of evidence we have that people are still thinking

    Far be it from me to defend Elon Musk but I think these articles are a bit of a beat up.

    From what I see the loss in DELIVERIES is due to transit time.

    Ships don't go every day so they have to be stockpiled on wharfs awaiting the arrival, then it takes time for the ship to reach Europe and unload.
    So the deliveries may be delayed to the next quarter. If there is a similar situation at the end of the second quarter then start to doubt.
    Imagine the delay if/when he starts shipping to OZ.

    I have not been able to confirm that - last steam in NSW was in February 1973, with the AD60 locomotive. This was kept on long after other steam locomotives, mainly because they were not only the most powerful locomotives in Australia at the time, but they were able to operate on all lines in the state, where most of the other powerful locos were restricted to main lines. Of course, these days (and for many years) the power of individual locos has been less important - they can operate as many as necessary as multiple units.

    Er I think they used to run a Garret and another engine up the hill from Brooklyn in the steam days.

    Yes - some grades regularly double banked in the steam days - but this is not the same as running multiple diesel-electrics. Each of the steam locos is fully crewed, but with multiple diesel locos only one crew is needed, and they are all controlled from the front one.

    So, the emissions output advantage of the EV will be a shorter time frame than he's calculated.

    I still don't think battery powered EVs are the long term future, and why the hydrogen fuel/fuel cell option is the best way forward .. long term.
    EVs now are the better option going into the future too, as they're easy(er) to then redesign to then switch over to a fuel cell setup.

    Wind power shouldn't be a difficult task to use as the option for H2 production in the future.
    The two downsides to wind power are lack of wind and what to do when there's too much power in the grid when the wind is still blowing?

    Both issues shouldn't be too hard to offset adding hydrolysis mechanisms into their operation(apart from other storage mechanisms) into their overall power setups.
    That is, when the wind is blowing and over capacity in the grid, then the wind turbine would then continue power production and channel that into hydrolysis.
    The current favoured path for power storage for wind power is to refill hydro stations as a battery/storage system .. but why not a localised hydrolysis system instead?

    What do you do when there's an excess of power production capability, and the grid is already at capacity? ... you keep the generators generating and then turn that into a potential energy .. whether that's battery storage(stupid idea on a large scale!) .. or refilling hydro network .. or better yet. . make H2

    My main issue is vehicle cost.
    I'm not rich, and I'm not the only one that's in this situation.
    $40-70K for a new car .. just to feel better about myself coz I'm doing a part for the environment .. never going to happen.
    Govt needs to step up to the task here and make it an option in whatever way they can .. eg. zero interest loans for exactly this purpose. eg. say I need $40-70K for a vehicle, if they had a 10-15yr no interest loan system that would cost me say $5K/yr to replay .. it'd be worth my while to seriously consider it.
    As of now tho .. to get finance for a car that will end up costing me 2x the amount of initial purchase over a 5 year term .. AND to lose all that value due to depreciation! .. err no thanks .. I'd rather keep on outputting my CO2 allocation

    There are literally million of 'Me's' in a similar situation .. a govt system would be 'household' means tested, so the already well off wouldn't then rip off the system to make it a viable mechanism.
    This way the glacial pace of uptake that is invariably inherent with any new tech would be accelerated .. and the usual supply/demand mechanism would take over and new industries and markets are formed .. jobs and growth as former political party used to shout and dance about not too long ago.

    if no one is driving hydrogen powered vehicles due to impossible an impossible price point, then the entire system is going to be a niche. lets say even 1000 vehicles on the roads .. across what ... 50K klms of road network?? .. how many refill stations would you expect to see?
    How much H2 production would you expect to be made?
    Give people the ability to buy into the system, x 1 million .. and I'm sure there's a rich fella somewhere rubbing their hands at the prospect of tapping into those billions.

    Same thing happened all those years ago with diesel fuelled vehicles and LPG.
    Even maybe 30 years ago .. try to find a non trucking type petrol station that sold diesel? Wasn't as easy as it is now. I can't remember the last time I drive past a petrol station that didn't sell diesel.
    Same with LPG .. had to drive for miles to fill up back in the mid to late 80's .. then the LPG rebate came up as a govt scheme, and BAM!
    Sorry don’t know how to do the mini quotes.

    To your original point: no calc’s on the transport and production of fossils. This just furthers the argument for EV’s, he gives ICE’s every benefit of the doubt and they still come out as higher emitters (not to mention the missing calculations). Then there’s the noxious emissions; nitrous oxides etc.

    EV’s are only a good economical choice for very few households (big yearly km’s and renewable self sufficient energy sources at home)

    Would love to see tax breaks but at the end of the day someone has to pay for it (us)

    There is a Diesel engine by achates I would like to see being produced in the interim. Manufacturers could use current machines to make the engine. Has less parts so production prices and emissions go down there, as well as the engine itself uses around 30% less fuel with good power

    Battery tech is moving at an exponential rate. Long term storage will evolve first and then storage for vehicles second (more tech hurdles). From what I have read, and if I understand correctly, when we have nanotechnology sussed/production process refined we will clock the silicon electrode batteries (I don’t fully understand this tech, just know to move forward has something to do with silicone/glass layer thickness)

    I’ve seen some interesting long range economic forecasts for EV v’s ICE. I don’t think we will have many personal use ICE vehicles being produced past 2025 and probably none past 2030

    I don’t know much about hydrogen. Never looked into it. It does get shot down rather quickly in any discussion i’ve ever seen, but I have to admit ignorance.

    In my view 2025 is a very unlikely date for EVs to replace conventional cars in the market. It is barely possible, but very unlikely.

    There are two major issues -

    Conventional cars have over a hundred years of experience behind their production, and for most producers, a lot of depreciated machinery. While it is possible to produce an EV that is essentially a re-engined version of an existing car, this is not going to be competitive with one designed from the ground up, either in performance or producibility; a battery bank has very different characteristics to a fuel tank, for example. For a long term solution, the whole production process has to be redesigned, and while a few manufacturers have started this, most have not, and six years to achieve it is, in my view, very optimistic.

    Secondly, mass production of suitable batteries is in its infancy, and capacity is also being required for power supply applications. And if, as you suggest, battery technology is developing at an exponential rate, this would mean that newly built production facilities are likely to have to be redesigned for quite different technology - hardly a recipe for rapid growth in production capacity.

    But, in sixty years of close interest in EVs, I have heard this sort of statement many times - and will believe it when I see it! Even if breakthrough technology were to be demonstrated tomorrow, for it to go to production rates able to supply the world's motor industries with batteries for most cars within six years would require a development speed unparalleled in industrial history. (I just know someone will suggest "mobile phones" but you need to realise that cars mass about a thousand times what phones do, and that mobile phones are built on electronics technology going back to the 1950's - with capabilities defines by "Moore's Law", proposed in 1965. No such growth has even been suggested in battery technology.)

    We now have batteries that are capable of producing usable EVs, and there are a few on the market. They will not replace ICE vehicles until they are cost comparable and readily available. Neither of these criteria are anywhere near today. Even if these criteria could be met within six years, I think that it is impossible for production to be built up that quickly.
