Thread: The future of Diesel cars

  1. #101
    The UK has 1/4 million miles of roads, times that by the number of lanes (single carriageway x 2, dual carriage way x4, motorway x6) the cost of installation would be staggering. Also peak time for vehicle charging demand would then be the same as peak time electric demand. Roads are busy from 7am until 7pm most often, as is peak commercial electric demand.
    We wil still need the extra electricity generating capacity. 24 miles a day at about 100K/wh per car per day (approx 4 miles per K/wh) and unless it is 100% real green energy then we are just moving the pollution around.

    The key is properly harnessing renewable energy or properly creating more nuke power stations (or both) When that happens, for sure we will fully convert to leccy motors. Until then, or more likely until fossil fuels are eroded to the point whereby someone cannot make filthy money from it, we shall continue to use the internal combustion engine

    As the topic has shifted to electric instead of diesel - I will just say I don't ever see if happening. Electric vehicles assumes two things that I can never see happening.

    First - large countries will need to physically shrink. Seriously though, I can see electric working in smaller and densely populated environs - but the technology is still light years away from allowing someone to drive across the American west (or Australian outback, or most of Russia).

    Secondly, and more substantial - wars will still be fought, and they will be fought in far reaches and in populated areas. In those developed and populated areas, the electric grid will be one of the first targets. Fossil fuel based transportation will still reign supreme if you wish to be a militarily effective country.

    Russia has enough resources to do what it wants and most of it moved by rail

    95% of Australia lives in a city. It is the most urbanized country on the world. Electric vehicles will do fine.

    Edit to add. Change that to 89% and not most urbanized but its up there for continent.

    "they will allow the grid to work...." etc assumes an awful lot that currently doesn't happen and may never happen under current UK operating regimes. They do not iron out any peaks unless you happen to have the diurnal demand to generation data for every region in the UK. The estimated total demand if we all switch to EV is more than the grid is capable of producing along with the required spinning reserve at any time of day or night. The unpalatable truth is that the UK simply does NOT have the infrastructure or reserves to handle this.

    All recent studies done by independent experts writing on this subject for government assessment of power security come to the same conclusions. Even without a switch to EVs, the rate at which we're currently going with demand and the decline of current power stations which aren't being replaced fast enough mean power outages as a planned operating feature of power delivery will become the norm, a sort of 5 day week for power generation. That will start to happen within the next decade unless power station replacement is sped up a lot. The knee-jerk closure of so many coal fired stations in such quick succession was done without thought to medium term impacts it seems without a long term procurement strategy already in place. That was a great example of planning to fail.

    Right on ChesterP and I can tell you Australia is in the same boat with both sides of politics pointing the finger at each other as they turn off station after station. Why on earth Australia exports uranium to France for nuclear power but don't have any running in the middle of the desert where we have tested nukes is beyond comprehension for most logical people.

    Induction charging? as in for each intake of breath you make?

    We're all just being financially conned!

    Induction charging while the vehicle is stationary is a good idea.
    There are stationary EV charging systems that can handle 3KW and transmit 93-95% of their power with an 8 inch gap between the transmitter and receiver.
    The problem is that to get that sort of efficiency, the receiver has to be perfectly aligned with the transmitter, move the vehicle a foot away in any direction and the efficiency drops drastically.
    How do you propose keeping the transmitter and receiver coils aligned when the vehicle is moving ?
    Also, anyone in the moving vehicle who has a pacemaker fitted had better watch out

    Induction is generally proposed for buses at busvstops for obvious reasons.
