    Default Electric vehicles

    There was an interesting article on the net at the week end.
    A guy in USA was having problems with his TESLA electric car.
    Small problem which his local mechanic could not fix, you need special training now to work on them.
    Went to the dealership who informed him the battery was stuffed and would cost him $16,000 to fit a new one.
    Went back to see his mate who managed somehow to get him one for only #$7500.

    Obviously one of the major problems with electric vehicle swill be ongoing problems with batteries.
    Conventional cars will go for maybe 250,000 miles on the one engine, batteries currently only good for around 55,000 miles before a new one is required.
    The main problem is the efficiency of them, rechargeable batteries on each recharge lose some efficiency to hold the full charge.
    Once down to around 60% in USA they have to be replaced, the ones taken out sold on to households to go with solar panels for back up.
    But once down to 40% not worth keeping.

    The electric car has about ten times the copper of a conventional one, problem now is that many of the current Copper mines are coming to the e nd of their useful life.
    New ones need to be found, which is proving to be harder than first thought.

    To add to the dilemma one minarologist said that by the hear 3000 the world will have used all the available natural resources such as Copper, iron, oil etc.
    But he added that there will still be one that man will revert to for heating and cooking, coal.
    Happy daze John in Oz.

    To produce 1 ton of Lithium requires approx 500,000 gallons of water.
    An electric vehicle becomes CO2 negative after driving 50,000 miles.
    Oh and they are good for the planet-aye right.

    We used to have Milk floats battery powered. Bread was delivered by Electric powered vans. Now we have millions who drive miles to buy milk and bread. We used to go to the local shops now we drive miles to go to a supermarket to buy our plastic wrapped groceries etc!!!
    Just now on TV is Richard Branson and some other bellend starting tourist space travel, bugger the pollution does not apply to the rich it seems.
    I don't understand this "fad" for tram systems, the initial infrastructure cost is huge. Trolley buses on the other hand and much cheaper and cost less for system maintenance, have less noise pollution so a win all round compared to trams, they could have dedicated lanes to avoid traffic hold ups. Last time I saw new ones was in Bergen 10 years ago, but the trend seems to be trams?

    Tony, like you I can't understand the rush to trams when Trolley buses would have been cheaper t install.
    Nottingham has a Tram system, which runs about 30m a year in the red, the bosses say this acceptable and is in line with their projections.
    Plans are in hand to expand it in all directions at a cost of 100ms, as it is publicly owned no one cares about costs.

    Re post 3 Lewis. On 11 a.m. news today they stated that 1 in 3 children are now living in poverty in England or U.K. , not sure which and the next story was Bazos with his space trip going ahead. Seems ridiculous that 1 man can afford such luxury when he is getting out of paying correct tax via all sorts of dodges when so many are in need. My opinion, but am social leaning in my politics.

    Latest news is that all motorways in England will in 2040 be fitted with overhead electric supply lines so that HGV's will be able to recharge whilst travelling. All HGVs' from 2040 will have to have technicon bridles fitted to their roofs (as in current trains) without them they will be banned from said motorways. Why Hull got rid of its trolley buses will never be known, probably because they worked too well!

    maybe that's why Thatcher closed all the mines, there's loads of coal still down there.

    I only remember going on a couple of trams, just after the war when they were still running alongside the Thames Embankment, and through
    the Blackwall Tunnel, I remember them to be a bit noisy and jerky, but I loved the double decker Trolley buses, in 1949 I used them to ride to
    the Public Baths to go swimming, a distance of about 2.5 miles, in those days the buses had clippies {conductors} I think the fare for that
    distance was one and a halfpenny for a child, cheers.

    Fingers crossed John, we are (the company I am working for) on the threshold of signing a contract with Tesla to supply a fire retardant product to make lightweight battery box covers. We beat all the competition during an arduous testing program, not bad for a small UK manufacturer!

    Anyone figured out where the electricity will come from?
