Until we have cold-fusion style infinite free energy, it will _never_ be efficient for people, often on a one-by-one basis, to wrap themselves in 4,000 pounds of metal and move that whole thing around an average of 50 miles daily. The idea that we expect this to become an efficient activity in the near future is absurd. We need inter and intra-city public transportation systems that work, and we need to rethink some of our values. Look at the poster above who dismissed ever getting an electric care because he goes on two 500 miles trips a year- did it ever occur to him that maybe he can rent a long-distance vehicle for his twice-yearly jaunts? ---

> [@Sam\_Stone](#): > > I don’t know… I think we’re too hard on the Volt sometimes. It really is a marvelous piece of engineering. Hats off to the engineers and designers who built that thing. It would be a practical piece of engineering if it had fast-charge batteries and it was a lot cheaper. From an engineering point of view it’s a re-worked Prius. It uses the same type of engine/transmission (reworked to favor extended battery mode) plus a lot more batteries. I wish people would stop referring to it as if anything new was invented. I don’t mean to insult the car but it is technically a conventional hybrid technology and should be viewed as such. It is not Og’s gift to mankind. > [@Sam\_Stone](#): > > I also think it makes as much sense to buy a Volt as it does to buy a Ferrari. And that sums it up nicely. People buy Mustangs because they can get a damn good sports car for a fraction of the money of a Ferrari. The fact that we’re funding the car twice with tax payer money (once for production and again in rebates) makes no economic sense if the goal is to make an environmental difference. I think the other taxpayer rescued car company has the right idea. Chrysler abandoned the hybrid market because it didn’t make money and used their high mileage cars to fill the void profitably. A car that gets great mileage and sells well is more useful than a car that gets super mileage but doesn’t sell. > [@Sam\_Stone](#): > > Both are cars that give up serious practicality in favor of stimulating an owner’s senses and values. I fully understand why a geek with a passion for the environment would get tremendous value out of a Volt. And in the meantime, they’re the early adopters that every market needs to succeed. Just as we early adopters in the computer age pretended we were doing highly practical, productive things by spending thousands of dollars on weak-assed computers that could actually do very little but make us wriggle in geeky happiness. But I’m sure glad we did it. This isn’t a function of early adopter sales. It’s a function of cost. People don’t buy Apple computers for one major reason and that’s cost. They buy a $299 computer that gets the job done. > [@Sam\_Stone](#): > > GM should sell it like that. Give it geek cachet. Make it hackable. That iPhone app that lets you talk to your car is a perfect example of what they’re doing right. GM has a fiduciary duty to the taxpayer and it’s stockholders to pay back the loan and make money. They should have kept the car on the shelf until batteries caught up with it. It could easily be the next Malibu or Taurus. > [@Sam\_Stone](#): > > But they are still trying to sell the car on the rationale that it will save you money, and the mass market people who are looking for a good transportation tool will do the math and realize it doesn’t really work that way yet. So it’s not penetrating the general market. At all. > > Another problem for the Volt is that other manufacturer’s cars are just getting really damned good. They’re becoming more fuel efficient at a faster rate than the government mandates, because the market is pushing them hard in that direction. I’m amazed at the fuel economy they’re pulling out of even the old big-block V8’s, and the new turbo 4’s coming out from several manufacturers are awesome. > > This means that conventional cars have been closing the gap with electrics, which makes the equation even worse for the electrics. If my choice is electric or an 18 mpg boring sedan, I might take the electric. If my choice is instead between it and a 247 HP practical car that gets 40 mpg, is great fun to drive, and costs half as much? Well… So to summarize your point, there are already cars on the road that offer more bang for the buck and people are buying them and not the Volt. Ford Mustang versus Ferrari. > [@Sam\_Stone](#): > > The energy density of gasoline is very hard to beat. So far, we’ve had to make serious compromises when trying to replace it. It’s a difficult engineering problem, and as of today we have no real ability to solve it. But we’re getting there. Patience, grasshoppers. It’s not a difficult engineering problem at all. It’s a battery issue. The Volt would go from zero to profitability in 5 seconds with a cheap, fast-charge battery. ---

Easy solution: 1. Increase tax on gas & diesel up to European price levels. 2. Let the market decide what transportation technology is appropriate. Unfortunately followed by: 1. Lose election. 2. Watch as new government repeals taxes. ---

> [@Mdcastleman](#): > > My impression was a non-rapid charger would take overnight, which would be unacceptable. Yes, 30 minutes is for a fast charger. But the technology isn’t theoretical; it already exists in CA along the I-5 route and some other places. For many Californians, the only long road trips they take with any frequency are between LA and Northern California, so this is enough (you can always rent on the rare occasions when you need more). They plan on building out over the whole country in the next few years. The cost needs to come down. But that’s pretty much it. There are still compromises with electrics, but they are outweighed by massive other benefits. ---

Today we think of a car as being all purpose for long trips or short ones. I believe to be practical a car traveling no more than 1 hour one way could be designed much different than an over the road car. A transportation vehicle could possibly weigh under 1,000# if it were only traveling say 20 miles max one way. Also reducing speeds to say 40 mph might help. ---

Solar power has gone down 98% in price in the last 40 years or so. I think it was $50 a watt back in the 70s, now you can get it for less than $1 a watt. Despite that massive price decrease, it is still only beginning to become competitive with fossil fuels, once you subtract the subsidies. With the subsidies it is competitive in sunny areas like the southwest. But that doesn’t matter, the tech keeps getting better and cheaper. Same with wind energy, the price decline was massive and around 2005 wind installation started growing dramatically, going from 47MW to 239MW from 2004 to 2011.

It doesn’t mean electric will ever totally replace fossil fuel cars but they do have a function. ---

Look at the poster above who dismissed ever getting an electric care because he goes on two 500 miles trips a year- did it ever occur to him that maybe he can rent a long-distance vehicle for his twice-yearly jaunts? inter-city public transit is pretty rare, at least here in the midwest. We have megabus now, and I sometimes use that to go from Indianapolis to Chicago. Those are good for trips, but not for a daily commute. As an example, in the times I’ve worked jobs I have always worked one job in one city and lived in a different one 20 miles a way. Since both cities were relatively small there was no transportation. But I guess that is what carpools are for. Damn I’m lazy. ---

Liquid fuels might continue to get better too. Maybe we’ll find a better way to make ethanol? Even if it’s still a net loss in energy you’re still taking something that’s nonportable, coal/nuclear/wind whatever electricity, and making a portable product so a net energy loss might be acceptable. I’m not sure what we’re arguing here anymore. If it’s that rapid-charge stations aren’t needed then I disagree since I don’t want to spend the night in Rockford when I drive to Chicage (and I don’t want to rent a car everytime I take a road trip). If it’s that electric cars will become practical if we get a couple of hundred miles of range plus stations to fill up on, then I’m in total agreement. As to a 1000 lb 40mph car, can you imagine taking that on the capitol beltway or any other freeway? I don’t think there’s that much of a market for a car that can never drive on a freeway, even as a “second” car for someone that lives in San Francisco or DC or someother anti-freeway city. ---

A person who needs a pickup truck twice a year might decide to buy a hatchback and spend $100 renting a truck when they need one. > > Electric cars are currently a novelty, and fill a small niche in utility. Expand the range and they’ll be able to fill a much larger role than they do today. I drive a Prius now. I drive twelve miles to work and twelve miles back - once in a while I stop by the grocery store and add another two miles. When we drive as a family, we use my husband’s larger gas guzzling sedan. A few times a year we need more than five passengers and rent or borrow a minivan. A electric car will eventually be perfect for me - provided that my husband drives a gas car. Fits the profile for me about perfectly. ---

But few cars are. > [@Chronos](#): > > … So the question is not whether we’ll end up with electric cars, but only how. Personally, I see the plug-in hybrid as the perfect transitional technology: Most users will be able to do most of their driving on battery, so there’s a sizable market for them, and in those uncommon instances where you need to go further than electric range, you’ve got the gasoline. Meanwhile, they still use the batteries and other electric infrastructure, so there will be a plausible route for them to improve incrementally, with the chargers getting better and more common and the electric range gradually increasing, until it will eventually be no hardship to give up the gasoline entirely… > [@Musicat](#): > > If the tech continues to get better and cheaper, why wouldn’t electric totally replace fossil fuel cars? These posts pretty well get it right. I love the concept of electric vehicles. I love the idea of never having to waste my time in a gas station again and am willing to pay some for that luxury. The issue is only how much extra I am willing to pay. My daily commute is typically under 20 miles a day. Sometimes more. We have another car that could be used for the road trip. But I was underwhelmed when I test drove the Nissan Leaf. It felt cheap. The Volt’s four seats are not the utility I need and it is priced on the higher end of my price range. The Ford Focus EV was nice, solid and peppy, but in comparison there is the (soon to be released) [Ford Energi C-Max](http://news.consumerreports.org/cars/2012/07/new-ford-c-max-energi-plug-in-hybrid-boasts-550-mile-range-95-mpg-equivalent.html) being released soon is less money with _more utility_. The vast majority of my miles will be gas free but when I need to drive long I can and without stopping very often either. Down side compared to all electric is that I still need oil changes (albeit somewhere between once every one or two years will likely suffice) and need to maintain an ICE (one that only runs for about 3 to 4K worth of miles a year for me but still). An all electric has no ICE to wear down, so much less to maintain. But the smaller batter will also cost less to replace than a big one (even though the cost will likely be much less by nine or ten years from now when it will likely happen). The Ford C-Max Energi is in _my_ sweet spot and all electric will need to come down in price relative to the plug-in hybrid/range extended EV before it will win out. I have my local dealer calling me as soon as they get them in. As to price analysis: the Ford C-Max Energi is decked out with the same features as the C-Max SEL. After the tax credit the price difference is about $2K. Even given the hybrid’s fantastic gas mileage the roughly 6,250 miles I’ll drive gas free (I figure 20 miles gas free a day 6 days a week … could be 7 but then again some days could be less than 20) will save me about 133 gallons of gas which cost over $4/gallon locally (and I only see than going up more over the coming years). That’s about $530 a year. Those 6,250 miles will cost me under $250 in electricity cost (likely significantly less given that I am using a $0.04/mile figure quoted with older EVs and using $0.11/kWh pricing and I would be using real time pricing for electricity, but use that). And it will save me an oil change a year at least, which for hybrids is the expensive synthetic stuff about $110/change. So I’ll be saving at least $390 a year. That’s a solid bottom base for my savings. If gas goes higher or my true electricity cost is less (which I think it is) then the savings is more. So as a base case my break even is 5 years and I tend to own cars for at least ten. Clearly for me worth it. Not even factoring in that I enjoy not contributing to our dependence of foreign oil and the decreased GHG emissions (even with 100% coal generation power much less and locally most is nuclear or natural gas). The Volt will be the choice for someone whose commute is a bit longer and who does need seating for five on occasion or the 42.8 cubic ft cargo carrying capacity that the Energi offers. A true all electric EV for someone who is very confident that their need will not exceed the range (such as because they have a second family car that suffices for those needs) and who values the benefits of no oil change or ICE maintenance more than I do. Someone who travels 350 miles a day should get a diesel methinks. The tech will get better and cheaper. BUt I do think **Chronos** is right: PHEVs are the transitional state. And the more of us who use those the better it is for those who use regular gas cars as we help decrease demand relative to supply. Win win. ---

Oh. As to the actual op. [Current Greenpeace position](http://ecowatch.org/2012/greenpeace-creates-the-roadmap-to-save-the-arctic-from-drilling/): > [@](#): > > “The way to reduce oil demand and end the threat of drilling in the fragile Arctic ecosystem along with eliminating demand to exploit other marginal oil sources is to make cars far more energy efficient and to make more use of electric transport systems powered by renewable energy,” said Sven Teske, Greenpeace International’s senior energy expert and co-author of the report. “The renewable power industry is improving rapidly, but the car industry is dragging its feet on offering the required new technologies.” … The transition to using electric vehicles, in both private vehicles and in an expanded public transport service, is key to reducing oil dependence and to implementing more energy efficiency. … So yeah, op’s premise is minimally out of date. ---

The biggest downside to battery-electric cars is winter. Especially in the middle part of the country where sub-zero-F temps are not uncommon in February and March, battery power is all but useless in the bitter cold. You either need to have an ICE back-up for those days, or ultra-cap technology must become practical for energy storage. No one wants to be stuck in the middle of frozen Wisconsin dairyland with a car that simply will not run because it is too cold out. You might be able to borrow some body heat from the cows, but you will never get your dignity back. ---

That’s a small corner of most roofs. It’s about $5k at current prices. It takes 13,000 watts to charge a Volt which gets you 45 miles on a charge when it’s nice out. 4 square meters of solar cells would produce abut 700 watts an hour on average. It would take over 18 hrs to charge up the car. So unless the owner works at night (allowing for daytime charging) and only drives to the mailbox at the end of the driveway, I don’t see a couple of square meters of solar sells as doing much good.
