Do we have any ENGINEERS on this thread or anyone who has the slightest idea WTF they're talking about?

Don Earl is AUTOMATICALLY excluded.

There are REASONS you don't see streets full of electric cars and it isn't because the Big 3 or the Big 2 was in collusion with the oil companies. We've had an international car market in this country for DECADES. And BOY, does Detroit know it!

The Japanese HAVE NO OIL. Why aren't THEY the ones who developed practical electric cars for their OWN use. They do have cars over there, you know. Not as many per capita as us, but they have them.

What of the Germans? They not only have no oil and lots of cars, but their own auto industry.

Here:

A gallon of gasoline has 1.3*10^8 joules of energy in it.

A AA battery has 10^3 joules. So it takes 1.3 *10^5 or 130,000 AA batteries to equal only ONE gallon of gas.

NOW do you begin to see the problem. Any idea what those would weigh? Or cost?

Let's do another one. A car moving at 40 mph is expending 10^5 watts (Joules/second). Let's say you want a range of 320 miles. That would take 8 hours or 480 minutes or 28,800 seconds or 2.88*10^9 Joules.

Now anybody know of a battery or batteries that contains that much energy that can be bought at a reasonable cost by the average person?

Let's get real, guys.
