    You do know that transmission losses for electricity is about 8%? Any idea of what the efficiency is for converting fossil fuel into electricity?

    What do those batteries cost in that dinky little car, and how often do you have to replace them?
    8 percent transmission loss is nothin compared to efficiency of gas motor which loses about 90 percent.

    Lost energy is inevitably heat. For gas engine to be efficient it would need to have exhaust at room temperature. You can roughly figure from that how badly gas engines actually suck.

    That is true... now think about the efficiency of turning oil or coal into electricity.... same rational holds true.

    Now store it in a battery. (note the heat given off by a battery charger)

    Now turn that electricity into motive power. (ever notice the cooling fins on powerful electric motors?)

    Do you still think electric cars are efficient?

    well what kind of idiot would use oil to produce electricity ?

    electricity should be produced from renewable energy sources like wind and solar.

    But that leads to a whole new discussion concerning an electric car during a point where most electricity is produced through renewable energy sources...something that's not currently true.

    So until that becomes true, the thing that poster is saying is a legitimate concern in regards to the situation CURRENTLY

    Sounds good..... on paper.

    Why are we ignoring things we know? We know that the sun doesn't always shine and that the wind doesn't always blow. That means that solar cells and wind energy systems don't always provide electric power. Nevertheless, solar and wind energy seem to have captured the public's support as potentially being the primary or total answer to our electric power needs.

    Solar cells and wind turbines are appealing because they are "renewables" with promising implications and because they emit no carbon dioxide during operation, which is certainly a plus. But because both are intermittent electric power generators, they cannot produce electricity "on demand," something that the public requires. We expect the lights to go on when we flip a switch, and we do not expect our computers to shut down as nature dictates.

    Solar and wind electricity are available only part of the time that consumers demand power. Solar cells produce no electric power at night, and clouds greatly reduce their output. The wind doesn't blow at a constant rate, and sometimes it does not blow at all.

    If large-scale electric energy storage were viable, solar and wind intermittency would be less of a problem. However, large-scale electric energy storage is possible only in the few locations where there are hydroelectric dams. But when we use hydroelectric dams for electric energy storage, we reduce their electric power output, which would otherwise have been used by consumers. In other words, we suffer a loss to gain power on demand from wind and solar

    But everyone knows that.

    Most studies I've seen have shown that the act of charging these vehicles is inefficient and actually will cause more polution than a conventional contemporary engine. If the grid was being mostly fed by nukes then maybe I'd buy one but it would have to sound like a Pontiac GXPR.

    Until we have almost all of our power supplied by Hydro or Nukes the electric car is just a Greenie delusion... kinda like those spiral florecent light bulbs that, in California, if you break one, by law you have to have a HasMat team come in and clean up the Mercury.

    Re: Would you buy an electric car?

    I just saw a SmithsonianHD channel (I think) documentary on ethanol from sugar cane. Apparently Brazil has gone from 80% dependency on foreign oil to <10% dependency by using flexfueled cars and mandating the availabilty of ethanol at the pump. They also showed a sugar cane operation in Hawaii where they take the depleted cane and process it as fuel for their generators which provide electric to the mill and 7% of Maui's total electricity production.

    If sugar is bad for you, and we already have a large portion of agricultural resources dedicated to its production, using it this way seems like it could make a significant contribution to the solution of our oil dependence problem without depleting the worlds food supply.

    Just please keep the fraud algore away from it!
