[GreenKeys] How much juice from a solar array?

[tony.podrasky]

Sounds like battery-powered cars.

A few years ago, my wife and I were looking to buy a new car.
My wife liked the Nissan X-Terra, so we went to the Nissan dealer.

While she was looking it over, I noticed that they had a LEAF
(100% electric). I took it for a test drive, and it was a blast!
It took off like a rocket, and as you pressed the "electric" pedal,
it just continued to increase speed without the bump of a transmission
shifting gears.

When we got back to the dealership, the manager asked me what I
thought about it. I told him that I loved it - but I'd need to
talk with someone who REALLY KNOWS how it works.

He said: "you're in luck - we have one of the engineers here from
the design team. He's here to teach the techs about it." I spent
about an hour with the engineer. At that time (2012) the battery
verses gasoline was a wash: the money you'd save on gas would be
spent replacing the battery packs.

Also, although Nissan said that LEAF would go 90 miles between
charges, I went on the internet and looked around. People were
complaining that the best they got out of it was 70-75 miles
per charge. While I normally just zip around town, maybe putting
10-20 miles during a trip, there are times when I go to San Diego
and that puts around 60-80 miles on the car.

I know that work is being done (world-wide) on making the
batteries better and cheaper.
