    Yes, and I gave you chapter and verse why it's useless. You did not respond with anything quantitative

    Ah, but you sure did. Lots of numbers. You must be right. Don't worry, we don't need to see any references on where you're getting your data. Only scientists worry about that sort of thing. Keep spouting numbers.

    If you wish to answer in the lanuage[sic] of physics and thermodynamics, I'm all for continuing this discussion.

    Dear God I'm not. You've gotten things wrong from your very first post. You don't know how the charging system works. You think the battery runs down to zero and then is useless. You think a lot of things that let me know that you probably haven't been within 100 yards of a Prius, yet you know all about them.

    You claim a lack of scientific rigor, then give me numbers on efficiency that have no provenance. You have quoted no sources. Which tips me off that you're no scientist at all. I even told you that you were pulling these numbers out of thin air and you still provided no references.

    And you continue to miss the point. Your statement is that the battery system is useless. I showed you that it was not. You state things that are absolute absurdities, such as this:

    But in this real world, is we assume the typical 90%/80%/90% efficiencies, the system only has a 65% efficiency, and that's assuming you're going down with no friction or air resistance.

    80% efficiency in a gasoline car??? You are mad. That's higher than the maximum Carnot efficiency for a gasoline engine! Real world numbers are far less, typically for a car about 25%. (See what I did there? I showed you where I'm getting my numbers from. Try it sometime.) So in any event, it's no small wonder you don't understand what I'm talking about. You don't comprehend basic physics.

    So I'm done discussing this with you. I believe I've encountered my very first physics troll. You couldn't possibly be that stupid and still be able to work a computer without getting pudding in the keys so I have come to the conclusion that you're merely trolling.

    You are out of your mind. Have problem arguing a point? Switch to a new one.

    We are talking about a coast-to-coast race. The coasts are very near sea level. The amount of ups very closely equals the amount of downs.

    No, we were talking about your claim of how the battery is useless on the freeway. That was your claim which I refuted. Then you decided to talk about the race. I am still debating the point that you made about the electric components being useless on the freeway.

    And BTW, your statement above does not support your claim of "the battery is useless on the freeway". It supports my position of "the battery is useful". Going down the hill it stores energy that would normally be lost. Going back up the hill it spends that stored energy.

    It doesn't matter if it's 65% efficient or 100% efficient or 5% efficient - that is energy that other cars simply lose. The Prius collects it and uses it when it is needed. And I know it works because I know how much gas this car uses. I own one. My record for best MPG over a full tank of gas was 53.1MPG. How do you account for that then? Are small winged faeries pissing ethanol into my fuel tank every night while I sleep?

    Simply put, you don't get it. And it appears you never will.

    And I still posit that you could not possibly be smarter than everyone at Toyota R&D. Your inability to grasp even simple engineering information is proof enough.

    Another fact: You've obviously never been in a Prius. Or paid attention if you were. You're an armchair expert - I actually own one, so I'd say I'm in a better position to tell the world what this car does do, and what it doesn't do.

    On a long highway trip sometimes the car will coast down inclines, charging the battery the whole way. More unassailable physics. Mine is called "gravitational potential energy". Yours is called "pulling numbers out of your ass".

    The car also runs the engine at the RPMs that allow for peak efficiency as often as possible. Any excess torque generated is sent - you guessed it - back through the electric motor to the batteries where it is stored until you need it. Peak efficiency at the gas side, spare torque for later at the electric side. Yes, even on the freeway.

    This is how I know you're full of BS. What you state is simply untrue. I can hop in my car right now, get on the freeway, and watch the electric motor add torque to the drive train. What you are telling me with statements like this:

    "Once the battery runs down it's all dead weight."

    ...is that you've never even been in a Prius. The battery never runs down. The control system charges it heavily around 50-60% for reasons of efficiency and battery life. It never gets lower than that. Not once in the 2.5 years I've owned mine. Ever.

    And if the battery charges up into the green (90-100%) and you're on the freeway, sometimes on a straightaway on the freeway the gas engine will turn off, and those "useless at freeway speeds" electric components will kick in and move you silently down the road. The embedded system on this car is brilliant. If it senses you're about to waste charge by having the battery at 100%, it'll start to lean harder on the battery.

    And if you doubt me, go make a friend with a Prius. Dial up the Energy screen and watch what the car is doing on the drive train. You can watch the system moving energy back and forth depending on road conditions, current speed, gas pedal position, etc.

    Again, you could not possibly be smarter than Toyota's entire R&D division. I know you think you are, but you aren't.

    Wow - you're smart! That's some good thinking there. I'll dash right out and gut my Prius of those gigantic useless batteries and electric motor that never gets used.

    My Prius generates its electricity through breaking. Not sure where you get the info about electricity generation in reverse during coasting.

    Switch your Info screen from Consumption to Energy, and watch what the drive train does when you're on the freeway and you let your foot off the gas pedal. You'll see it switch to charging the battery.

    The claim of 150 mpg even considering a 95% gasoline mixture would indicate a severe amount of tweaking to the engine. I've heard of 80 mpg (in Japan), but thats nowhere near 150 mpg. This makes the entire PR effort especially dubious in my opinion, even ignoring the fact that 95% of the fuel is simply conventional gasoline.

    Yeah, it's BS. The article mentions a plug. What they're doing is driving as far as they can, filling the car up with regular gas, squirting a little of this bio stuff in, then charging up the modified batteries at a plug in station.

    So you're right, it's bullcrap.

    Most folks would take a highway, where the electric motor and battery do not get used at all-- they're just useless weight.

    Not how it works at all. The electric motor in my Prius works at all speeds. It contributes to the drive chain when it makes sense to do so regardless of the speed. If I take my foot off the gas at 65mph the car coasts and the motor runs in reverse as a generator and charges the batteries. If I lightly rest my foot on the gas the gasoline motor stays off and the electric has enough torque to maintain speed. Until I hit an incline or need to accelerate, then the gas will pop on. Under most conditions if you watch the Energy display screen, you can see both the gas motor and the electric drive contributing at the same time.

    The whole system is pretty dynamic. It's not like there is a kill switch on the motors at 30mph.

    Much the same with DRM. They've lobbied for it, they've pushed it, they've gotten people to buy it and then yanked the key servers and left them high and dry. It can't be a swindle, they just haven't found the correct solution yet! So we go around and around with the industry talking about how to do this the right way.

    From what I understand, 'house cats' (i.e. cats that are raised solely by humans) never mature 'mentally' and are basicly stuck as kids for their life, as such they see their humans as 'mother'. Cats that are raised by other cats and allowed to mature mentally (i.e. learn to hunt, learn how to take care of their own young, etc) don't have this disability and thus tend to see humans as 'part of the colony'

    That makes perfect sense. I've heard the same thing about dogs - basically if they have people to raise them they remain mentally a puppy. That's why they bark. Youthful exuberance, like how puppies will yip and run in circles. It's puppy behavior.

    And while I don't want to take away from your feelings towards your cat, I have a feeling that when she smelt 'new birth and blood' on your hands the reason she did the laps around the house wasn't celebration but panic. In nature a male cat showing up with blood and birth smells means there is probably a kitten out there dead. Male cats aren't just "more of a danger than a benefit", they actively look for kittens and kill them as it brings the mothers into heat quicker.

    Yeah, I know that about male cats. And when I first showed up she was staring at me with a sort of horrified intensity. I'm sure that was the first thought on her mind.

    But you would have had to have seen her to understand. She wasn't hauling ass around looking for anything. She did circles around the living room. Pure speed, no searching for anything. I've seen her when she panics. Being a former outdoor cat when we have a thunderstorm she does indeed panic. It's unmistakable. The body language is totally different.

    This was not panic. It was joy, or as close to that feeling as a cat can get and display. She ran laps, pounced on another house cat and rolled around with her, loved on me a bunch then had dinner.

    I agree that on the face of it your explanation is more likely, but if you had seen her you'd know that just wasn't the case. And it went from there. This bizarre cat actually tries to encourage me to be a good parent. When I play with my kid or show affection she makes it a point to love on me. She knows deep down that males are dangerous to children, so she does her best to reinforce behavior in me that she sees as beneficial to the baby.

    Sometimes cats view people as other cats.

    I saw a special once where a bunch of female cats on a farm developed a community. They would feed each others kittens and arrange patrols to keep aggressive males away from the young. It was communal. They were a band of mothers doing a community job.

    And we have one cat here who decided same thing. We have three cats, two from a rescue shelter that were fixed as kittens, and one we found in our backyard pregnant. The cat that went through motherhood has mothering instincts, the other two do not.

    Two years ago my wife got pregnant.

    The mother cat knew exactly what was up, the other two did not. She would sit on her belly off to the side of the bulge and purr beside the child which would calm him down and make him sleep. She became very gingerly and delicate towards my wife. The other two didn't change their behavior - they'd step on my wife's belly and had no clue they were disturbing a baby.

    On the day the kid was born I stopped back from the hospital to feed the cats. I'm sure to a cat's senses I reeked of blood and birth. Mother cat was staring at me wild eyed with suspicion, taut as a bow string. I had never seen her so tense. I spoke to her in reassuring tones and let her smell my hands where I was holding the baby. As soon as she smelled "the baby is ok and dad here didn't hurt him" she took off like a rocket and ran laps around our house. She's very fat and I had honestly never seen her run before. The cat was celebrating. I know that seems unlikely and the sort of anthropomorphizing that pet owners often times overdo - but I swear...she was celebrating! She ran a few laps around the house, jumped on one of the other cats and went for a tumble, then started loving all over me. She knew. She is lethargic otherwise. A burst of energy from this cat is completely out of character. She knew.

    When the kid got home she "helped". You get a lot of visitors from people you don't see very often with a newborn in the house. Soon as one would show up, she would position herself near the baby, and *watch* the guest. Her intent was clear. "Harm that kid, do anything I don't like and I'll shred your face" It was the same pose and watchfulness she would do when her kittens were around (which we took to a no-kill shelter eventually - the same one we got our other two worthless cats from).

    And the cat would praise me for being a good parent. Male cats are more of a danger to kittens than a benefit. It seemed at first she was worried it was the same with people. Any time she'd see me being good to the kid (feeding/playing/whatever) she would make it a point to come up to me and love on me. Purr louder than a lawnmower and rub on my legs. She is a very vocal proponent of good parenting. Soon as I set the kid down she'd stop. Pick him back up, she's on again.

    But as for our other two cats - you're right. They definitely view us as parents, not equals. They will do that "kneading" thing with their front paws cats do when they sit on our laps. That's something kittens do to get more milk out of their mother. It's a baby reflex and they do it with us. But mom cat does not - she views us as fellow parents in the pack. So your observation is true if you have cats that have never been through parenthood, but occasionally that's not the case. YMMV though, of course. Cats are definitely unique individuals.
