    well i said a bit about it, but nearly all manufactures were cranking out EVs in the late 90's and early 00's. Honda has an EV to.

    GM hasn't gone to far with gas electric hybrids because they have been heavily going fuel cells. I would hardly say honda is spanky anyone with their "hybrids" they shouldn't even be called that seeing they are so lame far as hybrids. The toyotas are great. Good chance GM will launch something with them seeing their long time partnership. Acualy I think the VUE will be a hybrid soon. Also Toyota didn't create their system, its a seperate company that did and they are working with other companies.

    It's not car companies saying EVs arn't viable. It the entire engineering and science community. You can't change physics and thermodynamics. Much the same you can't change the laws of batteries. Differant chemistries have got us better batteries. But your basic lead acid battery has barely improved in 100 years when it comes to storage. And it's not for lack of trying with battery technology.

    Hybrids are the future. They use the benifits of both conventional and EV and apply them most effectively. This is the main reason companies have ditched EV research. Hybrids are just so much better there is no point in messing with EVs

    Sorry this is completely wrong. GM spent 1 billion dollars on the EV1 and leased about 500 of them in 2-3 states. THe reality is EVs are not practical. They are ok for when you cannot have any emissions out of a vehicle, and good for short trips. But they are not practical in the big picture. Your idea of who needs what is wrong. For one the numbers arn't right, and too who are you to say what people need.

    Now to the more important issue. EVs are not the answer. Like I said they are fine if you can't have any emissions from the vehicle, like inside a manufacturing plant, or in a dense urban environment. Not that the later matters since emmisions from else where will just drift in. What so many people miss is the power generation and so forth. From a well to wheels model (the greet model) that factors in all energy use from start to finish to move a vehicle such as makeing fuels and electricity and so forth EVs come out poorly. Infact Diesel engine vehicles come out on tops since the fuel takes very little energy to produce and few emissions plus the engine is very efficent. EVs are oen of the dirtiest forms of vehicles. Furthermore many think that a central power plant is cleaner, well aside from a nuclear plant or other no emissions plants this is not true. Most our power comes from fossil fuels. Powerplants are not high efficency do to safety. Also they simple are not very clean. The modern internal combustion engine is one of the most efficent forms of power generation we have. It's also one of the cleanest. If you own a LEV (low emmissions vehicle) in Los Angles the air coming out the exhaust is cleaner then the air that went into the engine. Our cars are now cleaning the air in highly poluted cities. There was also far less losses involved.

    EVs have their place but it is limited. The EV1 was only leased for liability issue. GM wanted to make sure things like the battery pack were properly handled. Also think of it this way. The EV1 had a range of 60-100 miles from it's 1200 lbs battery pack. A car like a ford focus that is much bigger can go 100 miles on 21lbs of gas ( ~3 gallons). The energy wasted to haul that battery pack is insane. Lithium ions help but don't make it practical. A pack that would have the storage of the EV1s battery pack ~90 Amp hours or so (trying to remember off hand) would cost roughly 75,000 bucks in lithium ion. This is based on a smaller battery pack for a hybrid vehicle I work on, compaired to the EV1 we have for a seperate project. GM gave the EV1s to universities after they were recalled, they were recalled do to a fire issue. EVs are not practical as full purpose vehicles. It is not an issue of conspiracy. People need to get over this. If the car companys had high mileage cars people would want they would sell them in a heart beat since they would make a ton of money.

    If you want EVs to happen. Invent a box roughly 1ftx1ftx2ft that holds as much energy as a gasoline tank the same size and weighs the same or less. Then they will be more possible. Also get fusion power working so we have a clean abundant energy source for EVs.

    And on a slightly differant note, when you come off as you did, no one will listen, because you sound like a crack pot. You have to have a open and logical mind for people to even listen. There is a small market for EVs, and it's pretty well used right now. Auto makers make EVs, but there is little market because there isn't many applications where they truely work. All EV pickups and minivans the big 3 made the last few years are out of production. I think the EV Rav4 may still be out there.

    I agree Highspeed trains will be nice. But even the fastest trains still are far slower then getting on a airplane to go cross country. Also the US is simpley huge. Think of how long Europe has been working on their train networks, both slow and highspeed. Now think of the US which barrly has any train network, and then finaly remember the US is bigger then all of Europe. It could take 100 years to get close to what other countries have. Also to be effective it needs to get to every town, which is really hard to do when everything is so spaced out. In areas where one city bumps into the next they work much better.

    No the flip side, trains are great expecialy if they come by all the time and you can just go down and buy a ticket and get on. That would be great. Also since I hate planes I would love them. I'm a mechanical engineer, I just can't deal with planes. All the way through college everything seamed to be about how airplaces fail, and riding in them I over-think ever sound they make. So I would love trains, the price has to be right though. I saw something saying a Acela (sp?) train ticket from DC-Boston was like 280 bucks, (note this could be wrong, it was something like that). Thats crazy. I would expect it to not be more then 30 bucks or so. If trains arn't dirt cheap it won't work. It shouldn't cost the same as a airplane ticket.

    Now here is something else. Planes have numbered days unless they come up with something. Planes need fuels like Kerosene and Diesel, that is, heavy hydrocarbons. Without such energy dense fuels they can't get off the ground. There is a limited supply of fossil fuels. It's projected to run out at any moment in the next 20-400 years (yes thats was making fun of dooms day predictions). Without such fuels airplanes are screwed. You can make fuel like Fisher Tropes Diesel, but that takes a lot of energy and isn't very clean to produce. It's hard enough to make the cost number works for planes as is, double the cost of fuel and hell really breaks loose.

    So as it stands now planes are screwed in the future, thus why most things talking about the future don't mention planes. You can't make an electric plane that would go very fast. And to power it you'd need a nuclear reactor up there. This makes you wonder what we will do for trans-ocean travel.

    So even though trains will be a bitch to move to and take a long time, they might just happen do to no other good answer.

    I think he ment things like fuel cell cars. Yes they exist, but they still arn't practical, and probably never will be. Since the whole fuel cell car idea is flawed. IE it's not freedom from fossil fuels since the practical way to get hydrogen is from fossil fuels. And even then that takes a lot of energy. They also arn't that efficient, 60% peak and thats not factoring the energy used to make the hyrdogen.

    Fusion power does even come into play, since the only true break from fossil fuels and to make it renewable is from splitting water. And that means we need a super clean, cheap and massive amount of power. Hense fusion, and even then you are still wasting energy making hydrogen, just means we have clean energy, even though making the hyrdrogen and then running the fuel cell puts us at a loss. So we can't really expect the promise of fuel cell/ hydrogen economy to come true till fusion gets up and running.

    Also far as hydrogen fuel cell cars they were promisied long ago, first 2000, then they all said 2004, now they say end of decade. Having worked on hybrid cars for years I and most anyone I know who works on hybrids and fuel cells agree fuel cell cars arn't going to happen. Especialy since a hydrogen IC engine beats a fuel cell in about all ways. Sure there is prototypes, and very complete ones at that, (fuel cell ford focus) and even some test fleets, but they are still nothing practical.

    For now the hydrogen economy is a nice fun thing for people like George Bush to throw out there. Make it sound good, oil companies love it, it's all good.

    The future for fuel cells are in laptops and cell phones were you by a small hydrogen cartrige. For uses where portable power is needed, and it must be clean. Things like stationary fuel cell powerplants are the silliest things ever. Since they need powerplant to make the hydrogen to power them.

    Yep, I haven't seen a chimp turn into a human lately either. Infact no one has ever seen this. Infact no person who understands evolution has ever said this would happen either. I don't know what belief system you are thinking of where animals change into other types of animals. Closest I know of is female frogs becoming male frogs.

    But then, the offspring of one animal being differant then it's parents is pretty common. Come to think of it I have never seen the offspring of one animal being identical to it's parents. I don't think anyone has ever seen to parents produce a animal identical in all ways to it down to the DNA. But childern being differant is real common, sometimes more differant thing simple looks, sometime they have differant colored parts, sometimes they have less then the normal ten fingers, sometimes more (i know a decent number of people born with 6 fingers per hand or 6 toes per foot), maybe they have the wrong number of teeth, I only was born with 22 permenant teeth. Some people i know are missing parts like spleens from birth. I'm sure thats just normal, I mean if every generation of offspring in something was just slightly differant for a few million years, i'm sure the end generation would be exactly the same as the first generation.

    You need to get over it and accept evolution as a fact, it typicaly takes millions of years, but for simplier things it happens very fast, bacteria and virus's evolve all the time, year to year. Other things like fruitflies have become whole new species in short observable time spans.

    It's impossible for things not to evolve, since to members of a species cannot reproduce and have an exact copy of them both in one animal, it will be differant. Only cloning can do this, and that involves only one parent, thus doesn't happen in nature. Evolution just means change, every generation is differant from the previous, in time the differances will show up. Just look at human over the last few hundred years, look at things like height, or general looks. If you took a sample of humans today, and a sample of humans from 1000 years ago and stripped them naked to remove all evidance giving away their timeframe it would be obvious who came from which time. Expand this over millions of years and out ape ancestors gradualy started to look like us.

    Evolution does not mean becoming "better" it might just cause you to like sex more thus create more young. Or maybe you give birth to more offspring and thus their is more of your species then another "superior" one and they can't compete and die out. Evolution in many aspects has been haulted in the modern world. Today if you are born with 6 fingers, society shuns that and wants to see them removed. Also they probably don't help you much. But millions of years ago in a tree, it may have made you a better climber or food gatherer. That made you stronger and the chicks digged it, they matted with you, and some of your kids had six fingers, and they had an advantage, over time their were more 6 finger people because they were more sucessful. Today such things don't happen, if you are not a classic human people shun you. being born with 6 asses is not likely to help you or give you any chance at matting.

    You also don't see much change in higher order land animal because we have become so much stronger and supress them. We kill them off to. As other animals have got smarter and adapted to our life we kill them off since we find them anoying, like bears living in cities living a new life from they did in the woods. Or we start seeing a change, say frogs with more legs, we set out to cure them, we asume its because of something we did. But there is a chance they are just evolving.
