    Look I think they are cool and that kind speed speaks to me but with unobtainium an perpetual motion at best itís a fun diversion for those willing to pony up the coin.
    Tesla has different batteries for different models, but 100kWh seems to be the new standard. Older cars had 60 kWh batteries. So I donít see how the amount of kWh used in the home is relevant.

    I think his point is that the vehicle would need a 500kWh or so battery in order to tow at the standards discussed earlier.

    I guess my only question with that is, could more juice be picked up from a 100 kWh battery? If the engines are four times as efficient, could the current engine put out four times as much power, or be used four times as long?

    Not trying to argue, I really don't know. I'd think that a very efficient set of motors could generate enough umph to rival a gas engine, while still being safe.
    The question isn’t could it do it more efficiently, they use diesel/electric locomotives for a reason. Hybrids when they came out procedures more MPGs. The biggest concern with electric is transferring the power from a source to the car unfortunately KWh from the grid compared to gas at the pump (which currently includes road tax your electricity doesn’t) is no cheaper. And with gas cheaper than it’s been in a decade it’s way cheap to burn Barney and Dino.

    Gasoline is pretty hard to beat.

    The technology with electric motors and batteries isn't there yet. If it was, you'd at least see a test vehicle out there.

    Electric motors can put out, but they need power.

    What else? Oh, burn a battery or gas? I don't want to burn a battery.... way more toxic than gas.
    Well we don't rent pigs and I figure it's better to say it right out front because a man that does like to rent pigs is... he's hard to stop.

    Has anyone here taken a ride in a Tesla? I did last year. The maxed out version at the time. A doctor I work with loves to show it off. But at the same time puts things into perspective. He didn’t buy it as a daily driver. I already understand that the internal combustion engine is a very inefficient design, electric motors are capable of spooling up to their potential way faster than the average gas engine (read massive torque here). The performance is astounding. But there are other electric vehicles and the only electric vehicles being discussed here are the balls out versions and somehow they’re being compared to daily driver gas powered vehicles. If you wanna compare a gas powered vehicle to the Tesla you’ll have to reach a little higher. Something way into the 6 figure price range (maybe 7?) that you’ll likely only get about 10-30k miles out of before its 10+ years old, caused you to go bankrupt or no longer viable. If you’re gonna compare electric cars to gas powered cars you might wanna research the true commuter and go with those stats.
    Btw, diesel electric. How do trains move all that weight ?

    If you go back to my original post, I specifically stated that making it affordable is the issue.

    Making it affordable is still years into the future.
    The rest of my comments were in regards to you assuming electric cars are more dangerous.

    Forget my numbers these are Teslaís numbers
    The model s takes 11.5kwh to go 34 miles compare that to a gallon of gas. This is the slow home charger and if itís operating with no parasitic loss itís drawing 48 amps. Your electric dryer draws less than 30Amps. Look at your energy bill.

    The technology has been around for a long time. Convincing people to pay for it is the issue.

    My energy bill is typically under $100/mo, so what’s your point?

    The rest of my comments were in regards to you assuming electric cars are more dangerous.
    And I added effective to your caveat because the transfer of energy back to the car to recharge it is not convenient for travel or in town delivery routes and varying other circumstances where gas is immediately available and this isn’t or takes forever to get you back on the road.

    The danger is real I would like to think they have designed these cars so that damage to the car would be highly unlikely to expose conductors but when you are talking high voltage it’s not like smelling a picture gas tank and it doesn’t require a spark to hurt you you just have to get too close you don’t even have to touch it.
