    You notice how he skipped over the Midwest question and referred to the dense populations of the East Coast and California. Living in the "flyover zone" we do not have overlapping large metro areas where people live and work with relatively short commuting distances. Somehow having to stop and recharge multiple times on a trip from one end of my state to the other or even on a commute to work lacks appeal. I'll happily stick with my hybrid Mariner.

    So the idea here is that rather than filling up at a gas station, you switch batteries at the switching station. That way, you don't have to wait for the car to recharge - a process that could take hours - when your battery is discharged. I guess you would put a deposit on the battery you receive and when you "fill up" your deposit would be transferred to the charged battery you would exchange for. Hmmm.

    For this to work and be worthwhile, it seems that electricity must be plentiful and produced from something other than fossil fuels. Here in Southern California, we have constant electricity shortages in the summer - so many more electricity plants would be necessary. If those plants are coal, oil, or natural gas powered, then the environmental problem is simply moved from the car to the generating station. Using coal rather than oil to produce the electricity would get us off oil, but I believe that coal is environmentally more harmful than oil - so what is the net benefit there.

    The most cost effective, environmentally neutral, and efficient solution to me would be a synthetic octane, made from carbon already in the environment and using green electricity such as windmills in the midwest. That way much of the existing gasoline infrastructure would continue to apply (a multi-trillion dollar asset we already have) and the carbon dioxide emitted would simply be returning CO2 to the atmosphere that was already there - a zero net change. Octane fuels have a really good energy density when compared to batteries. The problem is that we use a non-renewable resource, crude oil, to create today's octane fuels and, when we burn it, we introduce new CO2 to the atmosphere that wasn't there before. This increasies the concentration and thus changes our climate - how much is arguable. Now, just how this synthetic octance would be produced is the part that requires magic today. We need some wizards to figure this magic out.

      What even Shai Aggassi forgot to mention is that with his business model there is another major advantage. You make all cars uniformly use just one fuel = electricity and you transfer the burden of producing electricity to the grid. All future break troughs to produce electricity can be centrally done at the grid without reinventing the car every time a new type of fuel shows up on the market. Its much like a cell phone business model where you only care about how much talk time you are getting per dollar (in his case miles per dollar) without having to worry about how made the battery or what technology went into it.

    The U.S. government and its people need to support the building of nuclear power plants, along with other clean alternatives. The technology exists to deal with the waste. The main problem is to overcome the "not in my backyard" mentality.

    Electric cars would be a great idea...if batteries ever break the 20 mile barrier. Until then (and most battery companies don't expect them to for some time), hybrids will be the only feasible alternative.

    I think I would rather own and recharge the battery myself.

    HIs biggest mistake is to assume the model for U.S. transportation should be the automobile. It certainly wasn't in the WW I days when my grandmother, who lived in Memphis, TN, drove an electric. The national model was the railway system: inter-state rail lines, inter-city lines and even lines connecting suburbs with commercial areas. The car came into the picture and took it over. Time to return to the railway systems. Use electrics for urban and inter-urban commerce. For example, if I can take a comfortable commuter train from River Falls, WI to Madison, WI, about a three hour trip, for twenty dollars round trip, will I do that or spend six hours in a car, round trip? Other benefits, highway deaths would be reduced dramatically, which means radically reduced insurance costs, highway patrol costs and interstate maintenance costs. What we're going to have to get used to is using appropriate technologies for the tasks at hand rather than trying to force one option to fit all situations, as we did with petroleum powered vehicles.

      The problem with returning to a railway based system at this point is that our cities are built. Suburbs exist based on the assumption of cheap automotive travel. Changing this would cost trillions and trillions of dollars, and in many areas like Southern California where I live, wouldn't work at all. The automobile is with us to stay - we must find a way to power our cars in a sustainable way.

    It seems to me that some are not taking into account the fact that the power to drive these electric cars must first be generated at plants, which by a wide, wide majority are coal-fired. These generation plants contribute to CO2, and SO2, and other atmospheric pollutants. Not to mention heavy metals such as mercury.

    The time to charge the battery comes into play with regard to the distance factor. Today's batteries will take you 150 miles (using the example in the article, and of course they'll just improve with time); that's stopping every 2 hours or so on the road. That's not so bad, except how long does it take to recharge?

    For my daily commute to work, and for most Americans, electric cars would fit the bill. In fact, I might not need my gas-powered car at all. If I wanted to go on a long trip, I could rent a car. Having said that, I am disappointed that our leaders in the last 20+ years have not had the vision to expand the public transportation system. Eisenhower's interstate system was a huge step forward at it's time. Perhaps what high-speed rail could be for us now. When public transportation is really convenient, people use it.

    Everyone forgets to ask where the electricity to charge the batteries comes from. Unless we as a country are willing to seriously invest in nuclear enery we are still burning fossil fuels to make the electricity to power our cars.

  • Posted By: pdavidso @ 01/13/2009 1:33:23 PM

    The biggest problem I see with this idea is that if the battery only works for 150 miles (without air conditioning), it means way too many stops on a long-distance trip. This might work well for commuting to work or for short trips though.

    Electric cars are the future, it eliminates most carbon producing - ga s guzzling - middle east oil problems and presents future generations with clean air. Our government should have pushed this a long time ago, the industry will need their help in battery recycling and re-charging facilities if only current battery technology is used. I read of a couple companies who have made battery cars that go 250 miles on a charge and over 80MPH, all they need is lower cost batteries. I pray that the Obama administration is serious about a green nation for our children and develops a brain trust to effect this needed change instead of the current administration begging the Saudi's for more production.TLC.Day Oh

    Although electric cars may not be a viable alternative for the rural Midwest (which is where I am from), even the densely populated centers in the Midwest like Kansas City and Salt Lake City can benefit from the efficiencies of electric power. I do not think that there is a single solution to solving our automobile energy problems. Electric cars are a viable part of the solution. I am for reducing the amount of fossil fuels used in the US to what we produce (or less). The demand for oil will be there for the forseeable future and it would be nice if we could export oil and charge the prices OPEC charges us for a barrel of oil.

    Interesting how he didn't answer the question of viability in the "American Midwest"?

    • Posted By: 2cents @ 01/13/2009 1:25:59 PM

      The Mid-West will obviously have to wait until the infrastructure of the urban centers is up and running. This is the same way electric, phone, TV, highway and water infrastructure grew. What worries me is that people in cities do travel away from urban centers to visit relatives or go on vacations. If I can't drive from NYC to Pittsburgh I may not choose to buy one of these vehicles. Americans like to feel free to go where they want when they want. But I'm sure the infrastructure will expand rapidly if the experiments work.

  • Posted By: richdys @ 01/13/2009 1:21:44 PM

    Viability in the midwest will take longer. If you look at the history of Network technology (and building this infratstructure is basically a network issue) typically it takes longer to build out to the Rural market but you build the momentum in the urban centers. It was true for telephony and electricity in the early part of the 20th century and was true for the internet in the last half of the twentienth century. These guys are on to something. The only proviso is what additional strain will this put on the Electric grid. Now we will be burning oil or natural gas to create electricity which will be sent out over the grid to be loaded into cars. And he is right this won't happen without government help.

    Interesting how the objections are mostly based on erroneous readings of the information. EG: the article didn't say you had to stop every 30 miles to change batteries; it said you could go 150 miles, but that battery stations would be AVAILABLE every 30. And the comment that the electric car may not yet be viable in the "American Midwest," doesn't obviate its viability in the American urban centers, where most of the population and most of the pollution are located. weekend

    He didn't directly compare the price of electricity to gas on a per cent/mile, either. If he was really confident in his plans ability to compete directly with gas powered cars then he would compare on cents/mile basis for an all electric car against a gas car with similar size and weight and maximum fuel efficiency currently available. The second problem I have with this plan is when he mentioned having to put "switch" stations 30 miles apart. Americans are not going to significantly inconvenience themselves to switch to electric so, stopping every thirty miles to change batteries would never work. Until it is cheaper, and not any more trouble to drive electric, Americans will never buy this. Just a fact of life for now.
