  1. Re:I would like to know on Dept. of Energy Rejects Corn Fuel Future · · Score: 1

    The CVTs that you see in automobiles now are pretty much snowmobile transmissions on steroids.

    The ones in hybrids, at least the Prius (and I'm pretty certain the Escape is similar), are much different and don't use belts, though I doubt they would work well in a locomotive either:

    While I'm thinking about it, why aren't the car engines run like the train engines, with the diesel motor running at a more or less constant rate refueling the batteries that run the electric motors that actually turn the wheels

    I'm no expert, but I do drive an electric and have been following them for some time; my understanding is:

    In cars, the loss of efficiency from a two-stage power system makes the design pointless from that perspective, and few cars have enough room for both electric motors big enough to provide the necessary power and an ICE (Internal Combustion Engine) big enough to feed it. If you downsized the ICE to an average power size, then you have to have electrical storage to provide the extra when you need it, for as long as you'll need the extra oomph, which comes to the same battery tradeoff we have now with electrics: cost or size/weight, as well as needing even more space.

    In trains, the extra size/weight is an advantage (gives them more traction for pulling with), and such a setup solves the startup problem (diesel engines can't run at 0 rpm and a transmission that could handle that kind of power would be prohibitive and add maintenance costs), making the loss of efficiency worth it.

    I also have a hybrid Escape, and well, to be honest, I think the biggest factor in my better gas mileage is the graph that shows what my mileage is over time as I travel at different speeds. Slowing down 5mph made a huge difference ;-) (about 10-15%). The "official" reason is that they recover braking energy, but that's such a small factor that it's virtually useless. The batteries/electric motor do allow a smaller ICE, which uses less fuel in normal modes of operation than a larger engine would, and the electric provides the extra power when you need it, which is the sort of operation you are suggesting. The difference is that when the ICE is running, it's more or less directly providing power to the wheels, so you don't have the loss of efficiency from converting the energy to electricity first.

    It also has a sort of "constant velocity transmission" such that you never lug the engine. I think this is the source of most of its real efficiency advantages, as it's always running at the optimum rpm for the power it's producing. It also should make it last longer: it has a 10,000 mile oil change spec, and in looking at the oil at 10,000 miles, it's cleaner than regular cars' oil at 4,000...a reflection of not stressing the engine the way you do when you have to shift (rather than making bigger explosions, you immediately make a lot more of them, i.e. it revs up at the drop of a hat, keeping the internal pressures, and thus stresses, lower).

    I suspect this type of transmission might be viable in locomotives too, actually, and might be what they were talking about somewhere where I heard they were talking about a "hybrid locomotive", as it probably would improve their efficiency. I don't remember where that was though.

    That is a disadvantage for it as an SUV, however: without a real transmission, you don't get the torque multiplication effect of gearing down, and the thing is useless in snow country or any place where you actually need a lot of starting torque (i.e. when you're stuck). But over 40,000 miles, I average 26mpg, vs the rated 19 for the standard V6. On a warm, dry day on flat ground, I'll get over 30.

    It's "good" if no one likes it??? Sorry, I have a fundamental problem with that notion and can't just "let it ride" --- it smacks of nothing but snobbery to me... The authors of the music may not be good if it's derivative and unoriginal, but if you don't know the history and are just listening to it, that's irrelevant. The question is, "do you enjoy listening to it?" If so, then it's good. While that will vary depending on your mood, if a lot of people like it, it seems to me that by definition, it's good.

Do they have any information at all on how to actually *buy* one of their cool products? Not a peep. Are they doing PR or trying to sell a product?

They're no harder to manage (or not much) than that many physical machines, but it does make it a lot easier (cheaper!) to create new ones. And you don't virtualize a machine that's already using 50% of a real system. Or even 25%. Most of ours sit at 1% though. Modern processors are way overkill for most things they're being used for.

    Perhaps the advantage is that you'll be able to gain access to a giant catalog of movies as opposed to simply what is in stock? Furthermore, locations could offer this huge selection of movies without even having stock?


    A definite advantage to the store to expand the inventory without wasting space. A psychological advantage for stupid media execs who think that "using the same content-protection system as commercial discs" prevents piracy. To the knowledgeable consumer, it's massive waste of money the studios could turn into profit by just letting people download watermarked content. Then make sharing a watermarked file a parking ticket offense, and sharing a previously watermarked file a felony (i.e. where you stripped it out with a clear intent to distribute rather than just sharing it with a few friends like you would a real dvd). But no, rather than being interested in profit, the media execs are really interested in the illusion of control.

    Speculation about name actors like that is silly. They only way they'd use big names is if they wanted to be in it so bad they took a *major* pay cut. Trek movies just don't bring in Harry Potter/X-Men/Spidey $$$'s any more. It would take some major cahones to gamble that putting names in it would change that, when you're pretty much guaranteed at least a little profit if you use decent unknowns to make it relatively inexpensively. And if JJ does manage to resurrect interest with a good story, they win big with a less expensive production.

    And you're right: if this is to be a prequel, it needs 20-somethings in it.

    I have a Sony Portable Reader --- in fact since, surprisingly, no one here seems to have reviewed it, I'm trying to find time to write one, but it must use different E-ink technology. It doesn't have a backlight, and the contrast degrades rapidly with the light. If there's a lot of light, it is quite readable, and the background even looks white, but with just a single lamp or a couple normal incandescent lights, it goes gray with a very slight greenish cast. Admittedly, I've been reading most of my books on the very brightly backlit Treo 650 for the last couple years, and I'm getting old enough that my light sensitivity has noticeably diminished (though far from being a problem yet), but I find the Reader to be somewhat worse than a real book. While it's readable if you set things up properly, I still find the Treo to be the best reading device so far. The small size is only a disadvantage for figures and images, and Acrobat Reader for the Palm isn't perfect in its translation, but it works well enough.

    I would happily pay $2/episode for downloadable episodes of my favorite shows I could play when, where and how I choose, especially if it allowed niche market shows to continue and not be destroyed by stupid distributors (any number shows and Fox, for example).

    I will not watch, even for free, postage stamp, streaming in fits, enforced commercial crap as NBC is presenting. I haven't watched commercials in shows since I got a TV with a remote and a mute button, and I'm not going to start now. If they want me to watch commercials, they can make creative ones like the current Apple ads, and many superbowl ads. I'll happily go watch them. Just not in the middle of other shows.

    The key to fighting piracy is making legitimate viewing easier than pirating and charging reasonable prices. I believe that most people actually do want the shows they like to continue and will willingly support them if they can and it's not painful to do so. Right now, it's painful to do so. When that's fixed, piracy will resume its place as a nuisance, instead of being the showstopper.
