    Is it not about time that we saw more hi spec electric cars on our
    roads. I saw the Tesla Roadster and it outperforms a Ferarri on
    acceleration but what of teh charging time. Can we now re-charge in
    say 10 mins? The overnight charge is impractable unless the car is to
    be used for short distances from home.

    No.

    This is another reason why hybrids make more sense. Pure EVs have too many
    limitations.

  3. If they could recharge in 10 mins, the US power grid would burn out

    That is not the point, work out how much energy it takes to move say 1
    ton of metal a 100Km, with all the normal losses, like traffic lights,
    and going around bends in the road.

    If 20 cars are recharging in say a small city, say 5Km^2, at any one
    time, what are the total power requirements, and who has the capacity
    to provide that power?

    { fun.... }

    The ancient US electrical power distribution system would barf, and
    inwardly digest

    Around 30kWh.

    If you could recharge 30kWh in 10 mins, each recharging car is going to require
    180kW. 20 of those at any one time is 3.6MW.

    Energy wise, hybrids are only slightly better that the norm, and when
    we include recycling all those spent batteries, lousy low-temperaure
    performance and the ultimate source of the energy (coal and oil) it's
    a boondoggle. The solution is either significantly lighter vehicles
    (essentially electric bicycles with fairings), or horses. But when you
    think about it, they're unsustainable too. The only real solution is
    cutting the population of humans down by a factor of 10, and the only
    practical and "humane" way to do that is to release a virus that
    effectively sterilizes a whole generation, without prejudice.
    Bioterrorists, get to work! The alternative is involuntary extinction,
    pure and simple. Al Gore's been soft-peddling.

    Don't give me your problems! Give me your solutions!! What's the
    answer when the oil runs out?

    A bicycle, aromotherapy, reflexology, and a debit account with the
    Bank of Scientology PLC, a chiropractor, and condoms

    Make it a virus that only infects leftist weenies and those living on
    the government teat... THEN you have the answer ;-)

  12. Maybe, but just by culling the top 5% of the polluters, thats 25% of
    the pollution cured, this will reduce the need for expansion in china,
    so improving survival rate.

    In the short term anyway.........

    Yeah, AG has been soft peddling, damn commie republican

    The 'plug-in' hybrid hugely improves efficiency when it can run on battery power
    alone as is often the case.

    What's the big deal about recycling battteries ?

    I dare we'll soon see green eugenics.

    Oil's not running out. Conserving it (mainly not squandering it with huge V8 SUVs and
    the like) would help cheap oil last longer though.

  15. Rubbish, let the virus disable your corrupt government, then the
    lefties would have to get a job, less taxes needed, more production,
    more pollution, back to where we started.

    Ludicrous. Are you suggesting that, some Tuesday afternoon, the entire
    population of Earth will simultaneously die from heat stroke?

    Al Gore's been making $200,000 per lecture and burning vast amounts of
    private-jet fuel in the process.

    And homeopathic sodium chloride and colloidal silver.

    Let me tell you Martin, the lefties do have jobs, good
    technology-driven capitalist jobs, and they're raising
    more money from more donors than the bankrupt righties.

    If the world was populated only with rightist weenies,
    as Jim would prefer, I can tell you he'd not like it.
     
  19. And do the utilities have the capacity? Thats what I was really
    getting at
