The problem with electric cars

Wired.com has a review of the new Rolls Royce electric car here.  They note that the battery is the largest ever placed in a passenger car at 71 KWH.

Okay, how much is 71 KWH?  Well, one horsepower is 746 watts.  Do the math on this, and you’ll find this car can put out just under 50 horsepower for a couple of hours… maybe three or four if you’re really gingerly with it.

In other words, the biggest whopper of a car battery ever made could get you about an hour away from your house (two hours at most) before you turn around and come back home — assuming you want to coast into your driveway with the battery stone dead.  And then it takes all day to recharge.

Being a utility worker — you have to believe me on this — I’m rooting full bore, wide open for electric cars to succeed.  Yahoo, attaboy, go team.

Electric cars are great.  The on-board power inverters, sophisticated motors, aerodynamic bodies, and special noisemakers for blind pedestrians are poised in the starting blocks all revved up and smokin’ hot.  But battery technology is just not ready for prime time.  What else is there to say?  Chemistry students, can you help us out here?
