  1. Re:What's Taking Them? on High Efficiency Hybrid Car Planned For 2009 · · Score: 1

    We've been hearing announcements of cleaner vehicles for years and years. Even Lada demonstrated one last century! And what do we have? A handful of hybrids... Why is it taking so long?

    Why haven't you bought a Zap Xebra yet?

    why do the two hybrid cars I can buy here have gasoline engines and a fuel economy comparable to a diesel in the same price class, when they could (1) burn diesel, which has a much better fuel economy

    Diesel cars in the US were practically banned for several years, as they have to meet the emission regulations as gasoline fueled cars (trucks don't), but emissions controls generally won't work with the sulfur in US diesel fuel. Only in the past year has this changed.

    In addition, hybrids only give a big improvement in fuel consumption because they are strategically used in scenarios where gasoline engines are horribly inefficient. Diesel engines don't have those same problems to a tiny fraction of the same degree, so you add weight, complexity, and expense of a hybrid for a fraction as much of an improvement... Hybrids are just BARELY economic tacked onto gasoline cars, and wouldn't come close to breaking even on diesels.

    (2) use the combustion engine _only_ for electricity generation, so that it can run at its optimum efficiency?

    Converting mechanical motion into electricity, back to motion, is terribly inefficient, and would waste fuel, not save it.

    why not a more efficient engine (e.g. Sterling or Wankel instead of Otto)?

    Hybrids do have more-efficient engine designs than the Otto cycle.

    And why do we have cars that can run on up to 85% ethanol (the rest being gasoline) instead of 100%?

    Exceeding 85% Ethanol changes the characteristics of the fuel too much, so the engine must be redesigned to burn it. Who cares, really? We can't get enough of a supply of ethanol to give everyone in the world a 5% mixture, let alone 85%+. Everyone would be ecstatic if global oil demand was reduced by 80% overnight, and oil prices would positively plummet.

    And why do diesel cars not run on straight vegetable oil right out of the factory, even though you can get them converted for about 2 thousand euros,

    Because hundreds of millions of people paying 10% more for their vehicle, just so a fraction of 1% of their customers can use up the limited supply of cheap vegetable oil, is economically INSANE.

    Come on, people! It's not like there are unsolved technical problems here! The solutions are known, they are just not in mass-manufactured cars.

    None of the things you listed would solve any problems. Supplying enough ethanol or biodiesel is the problem, NOT using it... any vehicle can run on 20% mixtures of ethanol and biodiesel. Until everyone in the world can be supplied with that, no vehicle changes are needed. And your plan for hybrids won't help, and merely shows you have no idea of the actual problems.

    If it wasn't for that, straight vegetable oil would be cheaper than diesel here.

    Yes, destroying tropical rain forests to get clear land to grow vegetable oil crops is very inexpensive.

    Ravaging the topsoil that has been build up over centuries of sustainable farming certainly will allow the production of lots of fuel... for about decade or so.

    Well, not if you use crops that don't, or algae, which grow in deserts and on salt water and have a much higher yield anyway. And on and on.

    Huge amounts of money have been spent trying to get algae farms to work, and nobody has ever come close to making it even stay alive, let alone becoming economically competitive.

    And what magical crops do you have in mind that will grow better in the desert sand than fertilized soil, and don't need any water?

    An extra bonus is that the more you absorb the sun's energy as electricity, the less of it is converted to heat which dissipates around the planet, and that in and of itself reduces the effect global warming. So you are being twice as productive - not rely on heat-trapping coal, and reduce the amount of heat that saturates on the planet in the first place.

    Low efficiency solar cells will dramatically increase global warming. Instead of 90% of the sun's rays being reflected back off into space by nice light sand or white roofing materials, 90% will be absorbed by photovoltaic panels, and turned into heat either immediate (solar cells are inefficient) or after being used in the form of electricity.

    "Doing something wrong" usually amounts to changing some advanced setting that may be useful in some specific cases, but may cause problems in others. Or it may be the user (or the distribution) setting insane C/CPP/CXX flags before compilations, or applying unofficial patches, which the program can't possibly prevent. Often times, the problems fall to linked libraries that the user simply decided to remove. How could a program conceivably check all possible contingencies?

    This is a lot closer to a kite or a parachute. The ONLY similarity is has with a sail is that it happens to be powering a boat in this case. Far more differences than similarities, and I don't hear anyone complaining that sailing ships were just rip-offs of kites...

    Eliminating the huge weight, manpower, and most of the wear that was inherent with sails makes this a vastly different product that could well have been a revolution in naval technology (exploration, trade, warfare, etc.) if it was around in the 16th century.

    Republicans want big government.

    There is one single immutable fact of US politics. NOBODY EVER WANTS SMALLER GOVERNMENT.

    You can go all the way back to the first few presidents when the idea that presidential power had expanded too much and the government was too big was brought out for the first time, by some of the very founding fathers of the country like Thomas Jefferson. No doubt he believed it too, right up until he was elected, and it became HIS government, and he decided to expand the government, and expand Presidential power. In fact it has expanded at a pretty constant rate through the years, no matter who is in office.

    And when Republicans say it, they don't believe it for a second... Small Government is just a euphemism for deregulation, and senselessly cutting taxes and driving the country into massive debt (no, it's not just Bush, that's what they've all done, for the past 3 decades, he just happened to be better at it, having a rubber-stamp Congress). It's the same way that "state's rights" was just a euphemism for segregation, and NEVER meant to apply to any other rights, especially anything the party's base might disagree with.

    Democrats want immunity for big business.


    The Democrats went completely haywire when they lost the senate to Republicans. Now the entire Democrat strategy is to out-republican the Republicans. In 2004 we had Kerry trying to explain why he's just not quite exactly like George Bush, even though he voted in support of everything Bush wanted, and would continue the exact same policies, but of course he would do it in a different way. Then we have all the senators like Clinton voting for absolutely everything Bush wants, lest they be seen as not quite overzealous enough in mindlessly voting for anything that might eventually result in the death of an arab who may have made sandwiches for a terrorist organization. Even though they campaigned on being in opposition to Bush, and won an overwhelming victory, they're still fearful that he'll suddenly become vastly popular again, up from his 15%, days before they're up for reelection, and suddenly every NO vote will be used against them...

    Democrats have their own code as well. When they talk about women's rights, it tends to mean the right to chose to have an abortion or not, with no input from the other half of the pair that was involved, even though they can then demand child support and (p)alimony, even if they chose artificial insemination. When democrats talk about minorities or equal rights, they simply mean MORE rights and government subsidies/programs for women and non-whites, even in cases where the minorities may have already been treated as or more fairly than the (small) majority.

    K-12 schools may not be doing as well as they once were, but that's most definitely not the fault of the federal government in any way. And just because the few private schools can find ways to cut corners and get good numbers doesn't mean they would actually be a better, or even as good of a replacement when forced to include the rest of the population who couldn't normally afford it, and might not be as interested in being educated. There is a lot of self-selection there.
