Slightly OT...
I was at a hotel recently that had 2 parking spots for electric cars. Primo spots, right by the lobby. 2 spots right next to each other. I was there for 4 days and didn't see a single car being charged, day or night. (I was curious, so I kept checking)
My conclusion is that people do not like to stray far from home with an electric car. Perhaps battery swap locations would encourage more road trips.

These aren't D-cells. Consider a typical suburban gas station that fills, on average, 100 cars each hour. That's 2400 cars each day for which they'd need to stock battery packs. At about 5 cu. ft. per ea., that's a large volume of packs to stock (and recharge). Logistically, it's just not possible on a wide-scale.

It's only 2400 if you take a day to charge them.

Would be interesting to know how the distribution fits "morning drive to work", "lunchtime" and "getting off work". You don't get a day to recharge them.
There's a lot of gasoline in the pipeline between the well and the car. Imagine how many batteries it would take to replace the energy stored in that pipeline.

You don't need to, because you can charge batteries nicely in an hour.

You don't need to. Because you can charge a battery in an hour, you can't get petrol from the well to the pump in that time.

I think you're oversimplifying. It's quittin' time and 20 cars show up in the first ten minutes. How many batteries do you stock? How many forklifts? I don't know much about battery capacities, so scale to suit. Big round number is 100kWH x 20 = 2MWH in an hour. Where are you gonna get 2 Megawatts? Maybe it's half that??? Where are you gonna get a Megawatt? And how about the other three energy stations at that intersection?
There's no way, with current technology, to store massive amounts of electrical energy at the point of demand.
There's a HUGE amount of petroleum energy in the pipeline in train cars, storage depots, tanker trucks, on-site storage at gas stations. I suggest that there ain't enough electricity available to replace it in a way anywhere nearly as conveniently as "fill-er-up".
And, with current technology, what does pumping 100kW into a battery for an hour do to charge efficiency and battery life? Each 10% inefficiency costs you 10kWH. What do you do with the heat? How does temperature affect battery life?
Think deeper than the obvious.

Would be hard to achieve overnight. But we ain't all buying new cars overnight.

Why are you thinking about solar? You guys do have electricity to your home for heating, lighting, etc don't you? You can get enough current off that to charge a car in some hours.

Because at about 20 cents per KWh electricity isn't cheap - and at peak demand we can't get enough power from the grid to run everything else - much-less charge all the cars.

ur home for heating, lighting, etc don't you? You can get enough current off that to charge a car in some hours.

In the UK, it's 12p per kWh, and 1.10 a litre of petrol. Electricity is several times cheaper.
You don't have enough power for your current usage? Do you live in Canada or Bangladesh?

Are you on Ontario Hydro? I guess their little experiment with nukes didn't work well. I don't have a bill handy but most of my monthly bills are the flat rate charges that outweigh the actual usage except int the winter when I use some electric heat.

On Ontario Hydro - and the Nukes work just fine. It's just all the financial stupidity involved with a state run enterprise, combined with a virtual monopoly and too many British engineers.
Stupidity like paying ridiculous sallaries to embiciles to run the corporation, then paying them multi-million dollar severances to get rid of them when they screw up. And things like paying 6 or 8 times the retail rate for solar generated power that we can't use - and paying the eastern states to take it off our hands. And things like politicians dismantling and cancelling natural gas "peak" stations to get votes in the provincial election - at hundreds of millions of dollars in cost.
It's not the Nukes - it's the idiots......

It all started with a Republican governor who drank the deregulation KoolAid. MPC lost no time selling off their hydro and coal generating plants to out of state interests and entering the dot-com business just as the bubble burst.
The electric rates went through the roof, effectively putting several aluminum smelters out of business. It was so bad the pulp mill down the road brought in diesel generators before they closed down.
Luckily I'm in a co-op that goes back to the Rural Electrification days and contracts with the Bonneville Power Authority and my rates didn't jump appreciably.

Ever since deregulation the power company stopped trimming trees along the power lines. Consequently, when a thunderstorm/icestorm blows through, the power goes out for a couple days. It's of little comfort that I am *supposedly* saving $100/yr on electric. I can't imagine any consumer is actually better off with power deregulation.
I suppose the folks at Generac like it though.

CT Power got a lot of bad publicity a few years back for not enough tree trimming when an early snow took a lot of wires down. They increased the trimming and got a lot of bad publicity for excessive tree trimming.
So, here are my demands: Power will never go out I don't want any power plants within 1000 miles No cutting nature's trees When it is 100 degrees I want to be able to run the AC, the dryer, and charge my electric car I don't want to see wires I won't pay more than 5 cents a kW

There's the rub. The energy charge is $0.0690 / KWH. The base charge is $26.00, or more than twice the energy cost this month, so it's effectively $0.214 / KWH. Per KWH I do a lot better in the winter when the energy charge exceeds the base charge.

Nope, someone with economic sense. Look up figures on the loss due to depreciation of a new car. You should buy your car from 3-6 years old. Old enough to be a fraction of the price, new enough not to break down.
