So star trek wins because...... oh wow this thread is long now that I got lost and thought it was ST vs SW lol
If the World does evolve towards EV's in a big way China is certainly one of the few Countries who can pull it off.We know the US isn't going to do anything with EV and renewables anytime soon.
Really?
That's funny, we have several makers putting out EVs and the government funded a heck of a lot of R&D and is putting in 5,000 EV charging stations (initial roll out in just 5 states) and is providing a $7,500 tax credit for EVs (there are a number of States offering incentives as well).
As far as cars being produced:
Besides the well known GM Volt and several Tesla models there is:

I'm sure there's probably more....
and I just checked the IEA figures and if you add up the Renewable energy produced by Germany, France, Spain, Italy and the UK (gives slightly higher population than US) they produce about 25% less Renewable Energy than that US does (2008 figures).
US = 429,000 gigawatt hours to their 339,000 gigawatt hours.

The United States, which had maintained the top spot until 2008, fell another rung in 2010 to third with $34 billion in private clean energy investments.”
Latest U.S. sales totals for the Volt and the Leaf since launching late last year:
•Volt: 1,536 (608 in March)
•Leaf: 471 (298 in March)
Before we get too excited, lets put things into some perspective.... To be defeatist and claim it is a pipe dream is a bit naive considering the ingenuity being ploughed into the technology.
Lets say that is 100 days of sales or 15.36 cars / day, but in March ~21 cars/day.Latest U.S. sales totals for the Volt ... since launching late last year: 1,536 (608 in March)...
First quarter had 88 days.{post 1580}... Chery Automobile Co, ...sold 11,820 cars overseas, ...Its sales in the first quarter of the year climbed 11.8 percent year on year to 182,870 units. ..." {link ref in original here}
Chery is not a big international car maker, yet, but is selling many more cars that all electric vehicles combined, even now, and orders of magnitude more in five years I bet. ...
Summary: Volt sales are insignificant compared to even minor car company Chery.
The real question is how many Volts /day does GM need to sell to cease losing money on the Volt? {Anyone know the answer?} Are there that many NEW buyers coming to the dealers each day who, being very green motivated, will pay about twice what they would pay for a comparable IC engine car for mainly in city use? (For long trips, the Volt is a heavy, expensive, IC engine car.)
Volt has a little bit of a "catch 22" problem: If annual driven range is such that it is mainly an economical-to-use electric car, driven say 40 miles x350days = 14,000miles /year (or probably even less), then the IC engine car going only 14,000 miles, will at $4/gallon gas and 40mpg efficiency costs $1,400 for gas or have a operational cost of about $100 per month greater than the Volt. ($200 cost of annual electric power assumed.)
Summary for the used 80 miles per day, on average, case:Now for half the miles the Volt is an IC engine car, so for the extra 40 miles/day there is also no savings. Probably a slightly greater loss per day as in the IC mode, the Volt is hauling around a lot of battery weight, and a heavier, more complex drive system than the light weight small "city car," which like the Volt can be used for long trips too.
FINAL SUMMARYChoosing a Volt gives owner a "warm fuzzy feeling" of doing the right thing, but lacks much economic justification unless gas prices increase significantly more than $4/gallon; but in that case, a natural gas powered IC engine car is the economic choice for cars in the US for several decades. There are many times more natural gas re-fill station than recharge stations and the will be true for decades as natural gas powered cars become more attractive.
I did not read because I know most of night time power is base load power - often nuclear with zero CO2 pollution and certainly none is "wasted." What do you imagine? That they have big banks of electrical resistors to waste energy in? How is it "wasted"? Actually even the distribution system becomes more efficient. For example when supplying only half the power (half the current as Voltage is not changed) the RI^2 loss drop by 75%.http://www.squidoo.com/cheap-electric-car read the section about pollution: powerstations waste energy at night, energy that can be utilised by electric car usage.
I assumed that so the Volt, running only on recharged batteries, would have the best chance of economically competing with the small in-town use IC engine car. I was not saying that the Volt could only go 40 miles... Except Billy the market for the car isn't for people who only drive 40 miles per day.
No; My logic includes the natural gas car alternative. You logic ignores that, so is probably false logic.... Except you presume that Volt owners won't be able to charge on the go, and they will. Indeed over the 6 to 10 years someone owns a Volt a LOT more charging stations will become available, and here's the thing Billy, the Volt will be much more attractive to people who know that they CAN recharge their Volt at their work place or during their normal use.
http://www.evchargernews.com/#regions Big OOPS in your logic there.
"Planned" and "Built" are two different things. True, the commercially sold NG car is also in the start up phase but also true that many gasoline cars have been or can be cheaply converted to NG. A lab technician in my old APL group drove more than 100 miles just for work 5 days /week. - He installed an NG conversion kit, ~50 years ago. He had NG heating in his home and made his own filling station with small pump. Total cost of everything < $500.... There is only one Natural gas car being sold in the US Billy and that's a small Honda GX that goes for $27,000 and there are far more electric recharge stations being planned for the next few years than there are NG stations, so no, NG at this time is really not a very practical choice in the US.

I doubt there will ever be as many open road recharge station as there are natural gas refill stations. (More soon on your ignoring the NG alternative). NG is used to fill trailer/ camper cook stove tanks, etc as well as car tanks.
While most driving is almost always done locally, the advantage of the Volt is you can drive it intercity if you need to with no need to worry about recharging. Initial buyers of the Volt will likely be a high percent of people who do have the ability to recharge at their normal commute locations though (just logical), and of course over the next few years that number will only increase as more and more recharging stations are built.In my opinion the Volt's economic advantage is ONLY valid for use in the city, and at present only for either total trip of less than 40 miles or with 7 hour recharge at your work place as you suggest for <80 miles of daily use.

much cheaper and well proven by decades of use, NG car, especially now that NG is falling in price and dramatically growing in proven supply (100 years or so). Switching car types is a cost conscious new task the US must do. EVs are not going to be the winner - too capital intensive a switch and zero long term history.
Probably true now that warranty would be voided (unless one of the conversion kit companies does the job and assumes it.)... Conversions {to NG} are not likely to ever be a big percent of our market, you void your warranty by doing so.
We'll see, but right now I'm not seeing any move towards this in the US at least. Arthur

I see no reason why Ford, etc. can not offer a conversion with continued warranty. -Not much demand for that yet, but there will be when driving on NG is less than half the cost per mile driven.
Any car produced in small volume (i.e. the NG Civic version) will cost a lot more. - your point not valid, if based only on the higher cost of the NG version.The problem is pretty simple:
Here's the CNG version of the Civic that costs $25,000 and gets ~28 MPGe
http://automobiles.honda.com/civic-gx/
Here's the Gas version of the Civic and it costs $15,000 and gets ~28 MPG
http://automobiles.honda.com/civic-sedan/
Here's the Hybrid version of the Civic and it costs $24,000 and gets 41 MPG
So, even at half the price of NG vs Gas (per mile) after paying the $10,000 premium for NG you would have to drive 150,000 miles in the normal Civic before you start saving money with the NG version. That's a LOT of miles.
The CNG version is a bit better deal than the Hybrid, but probably not enough to make up for the problem most buyers would have with finding CNG.
So currently this is why CNG isn't overly attractive to car buyers.
