  1. Re:Is more powerful more, or less, efficient? on The World's Most Powerful Diesel Engine · · Score: 1

    I guess that is the fact and when you think 'diesel engine' includes a jet engine that runs on diesel, the engine people blow a gasket... For consistency, do they object to calling 'diesel fuel' plain 'diesel' too?

    "Those aren't Diesel engines. Those are engines that burn diesel fuel. Diesel fuel is named after the engine, not the other way around."

    You are right if by "diesel engine" you mean "Diesel's engine" instead of "an engine that runs on diesel fuel" and I guess many people do so and feel the trucks engine should be called something like 'diesel jet engine'... that explains some of the reactions I've been getting ;-)

    What I don't get is the anymosity towards using the combined meaning of the word 'diesel' to mean diesel fuel and then 'diesel engine' to mean an engine that uses diesel fuel... It seems to be stronger than using the word 'hacker' to mean a 'cracker'.

    But Diesel's engine ran on peanut oil (which is not even a nut). If 'diesel fuel' is named after the engine, then why isn't is peanut oil?

    If Diesel showed his engine with peanut oil, and diesel fuel is not peanut oil but a crude derivative that works well in Diesel's engine (weakening the grammatic linkage of 'diesel' to Mr Diesel), then why is an engine that used diesel fuel not a diesel engine as it would be under normal english grammar?

    Oh, well, I give up, too many people don't like 'diesel engine' to include the jets... I still like the jet engines more though...

    Where you get that I say that jet engines have a torque rating is a mystery. The rest, well, I'll just remind you that torque is a measure of 'work', not 'power', hence calling the cylinderblock the most power-full engine based on its torque rating is nonsense, and if you can grasp that then maybe you are the 'dumbass'.

    "Jesus christ you fucktard. Those are turbojets."

    Sure anonymous, mannerless fool and coward, they actually run on Diesel as their only fuel. http://www.shockwavejets.com/shockwave.cfm

    The cylinder block yields less than 8K horsepower per cylinder, these jets 12K per turbine. Then mount 14 of them in a block and call it an engine, the jets will weight less and have more power.

    Saying that the Jet turbine in the truck is useless is quite ignorant. Sure, this guy uses it to push a custom rig down the track with added auditory and visual effects for entertainment purposes only. However, doing things for entertainment purposes only is hardly useless (it draws many crowds that very much appreciate the show). If you wish to disagree with that, then fine: Try, for example, building anything that flies with that heavy box of elevators diesel engine. In the truck, the engines are actually pushing down to prevent the rig from becoming airborne. I think a 36K horsepower set of turbines running on Diesel of all fuels if pretty cool, much cooler than a supersized cylinder block.

    While this engine may be the highest torque engine, that is not what the article says. This is supposedly the most 'powerful' diesel engine. Saying torque and power are the same thing is nonsense.

    'torque' only applies for things that are _rotating_ http://en.wikipedia.org/wiki/Torque

    You don't need rotation for power.

    Power is expressed in Watts and there is a linear relationship between horsepower and watts (746Watt per HP).

    "Hey pal, if you had read the story you linked to, you would have known that the engines in this truck are JET engines, with diesel injected at the exhaust outlet to generate flames and smoke for visual effect."

    Right 'pal', it has jet engines all right, but contrary to what you think they run completely on Diesel. I think that's pretty cool, it beats elevator sized cylinders if you ask me. The added Diesel for the flames is just to improve the mile-gaseage...

    http://www.shockwavejets.com/shockwave.cfm

    I'll grant it to the first replier that says the engine in the article is 7780 horses per cylinder times 14 cylinders, but who's to say you can't mount 10 of these jets onto a frame and call it even bigger? Judging by the pictures the Jet engine is more compact per horsepower than the elevator box.

    Well, if you pay close attention to a zipper, you will see that the nodules at either side of the zipper don't pass. In fact, if they do, the zipper gets stuck: That means that when people pass others to merge at the last moment, they have already broken the zipper by passing. It's not the merging in the end that is the problem, it's the passing that happens right before that that breaks the zipper.

    "(or do they have multiple ground pins?)"

    Multiple? More than half the pins on ICs like such CPUs are usually for power, not just to keep the input power stable, but also to prevent 'ground bounce' where the ground goes up from 0v when the chip draws a peak current.

    And, hum, 'just' add a 'power sensor'? You can measure strong currents with a coil around the wire, or smaller currents with a small resistor in-line (and then measuring the voltage over the resistor), but both influence the power flowing from/to the chip in an unwanted way, so that's not likely what you want.

    Unless you have one of them 'James Brown' power sensors ('can you feel da powa').

    Only an anonymous coward would post such nonsense.

    If you think you ever have _any_ technology for a fuel that does not 'take more energy to PRODUCE than is produced by its consumption', please file it where it belongs: under 'perpetuum mobile', or if it takes the same energy, file it under 'erroneous', because you probably forgot to account for some energy loss somewhere in the process.

    The 'Hydrogen economy' is not about replacing our fuels with hydrogen as a new fuel. Don't look at it as another form of 'coal', but look at it as anther form of 'electricity', with some very unique and promising advantages.

    'Hydrogen economy' is about using what hydrogen technology makes possible in the energy generation, distribution and storage system.

    One of the many possibilities is that it creates the opportunity to replace gasoline for pouring into our cars. Another is that hydrogen storage and a fuell cell will end up being cheaper and more practical/durable than batteries and an inverter.
