http://www.dailymail.co.uk/news/article ... z1jZKGFgT2 Quote: Just 2,149 electric cars have been sold since 2006, despite a government scheme last year offering customers up to £5,000 towards the cost of a vehicle. I'm surprised that any electric cars have been sold. Twice the price of a conventionally powered car, a maximum theoretical range that is impractical, a refuelling time that is ridiculous, and a battery life that is very likely to be an economic and environmental disaster.

It's also been reported that when the batteries do eventually die you could be looking at a £10k+ bill to replace them. You really do need to do your homework when buying a car. My car is a 1.8 petrol, they also do a 2.2 diesel that returns circa 20% more MPG. However, the servicing of these diesel cars is significantly more expensive and one member on the car forum I visit has done the maths and he is out of pocket and will be buying petrol next time. |

When they do the maths for Wind Farms working out how much energy they generate against the cost of installation and environmental damage they do they will also be found to be a white elephant. The tree huggers are driving the agenda where the Government must be seen to be doing something even if it is the wrong thing, hence wind farms. Plus of course there will be a few million in for their mates and a few directorships at the end of the line. |

Batteries have a charge-discharge cycle life expectancy. And from the beginning of those cycles the batteries progressively become less efficient. This document http://www.kfb.se/pdfer/M-99-28.pdf helps to explain the life cycles and efficiencies of various battery types used in electric vehicles. Page 6 contains a table indicating the charge-discharge life cycles of various battery types. A battery with a life cycle of a 1000 charge-discharges used for daily commuting and charged at the end of each journey could be subjected to two charge-discharge cycles per day. Assuming the battery efficiency remained constant throughout its life, which it doesn't, it progressively deteriorates, then a battery would require replacement in lass than 500 days. Who wants to replace expensive batteries every 18 months to two years or so? What would be the trade-in value of an electric vehicle after a year or so? Who in their right mind would consider buying a used electric car with unknown battery condition? Even unused or low mileage battery cars are going to be a high risk purchase; batteries deteriorate over time once the battery has been first charged, even when not subsequently used. |

If it were not for the tree huggers we wouldn't even need electric cars..... Ask yourself does the US have a large electric motor industry? Though this may explain why..... http://en.wikipedia.org/wiki/Who_Killed_the_Electric_Car%3F |

We do need some serious and efficient tree cutters though. There is an insanity abroad that has found a willing resonance in the hearts and minds of the high and mighty of the political, religious, educational, artistic, and economic spheres; an insanity that has abolished sound reasoning and rationality. This insanity has been encouraged in order to destroy all that is just, righteous, good, and of real and lasting benefit to mankind; and in the place of all that is wise and proper has been unleashed an all-encompassing liberal folly on a grand scale, a liberal treachery that seeks to control us from cradle to grave and lead us to hell and destruction. |

I remember being given the impression at school that there would soon be no forests left because they were all being cut down for paper. Total rubbish of course, paper companies plant their own trees for paper, nothing could be more renewable than paper and trees, but it was well into adulthood before I realised (and read) what a load of nonsensical propaganda I'd grown up believing. |

Took part, as a volunteer, years ago growing hybrid poplar for the pulp paper industry. The basic idea was that they grew fast but instead of felling the entire tree machines `harvested' the topmost branches only; this could be repeated, like a pollard willow, every few years. As a side note also remember the paper industry here uses waste residue as a fuel for their boilers to economize on fuel ! Modern `TimberJack' machinery cuts only to the onboard computer requirements, constantly updated by radio from the mill, strips surplus bark and branches on site then mulches it into the forest floor right where the lumber is cut !!! |
