It has a battery and electric motors. So? Your car still has an internal combustion engine. Is it the same as a Model A? Yes. The internal combustion engine has not changed much in 100 years either. Bull****! That's a very ignorant statement! Specifically what has changed? Metals used, fuel delivery systems, advances in combustion technology, advances in exhaust technology, much better efficiency, electronics for combustion, fuel efficiency, engine control, emissions, and on and on... Those are all just improvements on something that already existed. Well, I guess the same could be said of computing then. Same as it was in 1850 because DC current works the same now as it did then!!! Makes just as much sense as your posit. |

That's all you know about a modern internal combustion engine? Figures. http://www.ehow.com/about_5132937_hi...bocharger.html As I said the internal compustion automobile hasn't changed in 100 years. And tires on your car are exactly the same as when the caveman carved a wheel out of stone..... got it.... |

Battery technology has advanced a lot, and the Volt is a much more comfortable, faster, safer and luxurious car than anything that existed 100 years ago. I'd buy one now if the price was more in line. Remind me to post a picture of my neighbors electric boat one of these days. It looks better and better every time the price of fuel goes up. But that's not what FOX told him.... What advances in batteries have we made in the last 100 years? Reduced weight, higher power. Think Li. Carbon based nanotube ultracapacitors, and on and on. http://www.technologyreview.com/news...ecent-battery- advances/ http://www.technologyreview.com/news...ies-charge-up/ I've heard it all before. I know all about charging and discharging cycles and issues. The materials may have improved but, the basic battery is still the same. You charge it, you discharge it, you charge it and the cycle keeps repeating until the battery wears out. That's like saying that automobiles are the same as they were when Henry first built one. Hey, the still have internal combustion engines, so using your analogy, they must still be the same! What has changed in an internal combustion automobile in the last 100 years? Fuel delivery... Turbo's, fuel injection... Same old engine with a few refinements. Yup, the "technologoy" hasn't changed, but then again, it came in viable.... New technology isn't always better technology, if so, doctors would have fuel injected Leeches in jars on their shelves  Hasn't changed??? Are you serious??? Yes. The components of an internal combustion automobile have not changed in 100 years. They may have had some refinements but they are basically the same. And computing hasn't changed since 1850 because DC current still flows the same way... got it..... |

As I said the internal compustion automobile hasn't changed in 100 years. I think the point is that while the basic operating principles of the internal combustion engine haven't changed, the efficiency and reliability of it has dramatically increased in those 100 years. Solar energy hasn't been cost effective in the past, and is just starting to become an alternative now. If enough advances are made to its efficiency and reliability (longivity) in the next few years, it could become an attractive option. Same for electric cars, etc. Technology marches forward, just sometimes slower than we'd like. |
