  • Your numbers are not correct. Can you cite sources for them?

    Even then you tried to weasel your way out by claiming your motor would indirectly charge your battery, which it doesnt.

    Can you clarify this? The motor does both directly and indirectly charge the battery in most (if not all) hybrid cars.

    You wrongly assumed hybrids were using the motor to charge the battery, which they don’t.

    Yep there it is again. Definitely not trusting your armchair understanding of physics and automotive engineering.

    Tell you what. Cite one example of a production vehicle where they removed they hybrid system and gained fuel economy, and I’ll admit that ICEs alone are much more efficient. Until then, you’re wrong, I’m right, and I have 3 real world examples to back it up.


  • No need to admit anything. Here you are insinuating that my statement about the heat generated by EVs and ICEs is not correct…

    We would just put diesel generators in the trunk if any of that would make sense.

    That was your primary response to my statement that EVs generate an insignificant amount of heat compared to ICEs.

    You also said this…

    Youre arguing against the principle of physics.

    What makes a Diesel generator better then … Checks notes… a Diesel Generator?

    And the answer, which I gave you is that a diesel generator is not the same thing operating under the same load and conditions as a diesel car.

    I also provided 3 real world examples of hybrid systems that outperform their combustion counterparts. I will admit that I was unable to locate specifically a hybrid diesel car, or an electric car with a diesel range extender.






  • Your Argument is that it’s more efficient to charge an EV with a diesel generator than using it to combust in the car directly.

    Yes, that is the premise. To put it as simply as possible, a diesel generator powering an electric drivetrain can always run in it’s peak efficiency band. A Diesel Engine directly moving a vehicle is not. If you had a perfectly flat course, and vehicle a running at constant speeds for extended periods of time at a speed that matches the peak efficiency of the diesel engine, then it would be the better option.

    The fact is, hybrid systems are more efficient in real world conditons. We have hybrid cars all over the place, which are more efficient than their gas only counterparts.



  • We actually do. The BMW i3 came with a gas generator as an optional range extender feature. It was not very popular. The majority of drivers drive less than 40 miles a day, and EVs easily encompass that distance, even if you have to run the heat.

    And yes, an electric vehicle powered by a combustion motor absolutely is better in terms of efficiency down to extremely small scales. We’ve been using diesel electric vehicles for decades now because of their efficiency, torque, and long service life. They’re called ‘trains’.



  • To clarify, ICE produce so much waste heat that defrosting and heating your car is essentially free (energetically speaking) because the car needed to dump that excess heat anyway.

    BEVs don’t even generate enough waste heat to maintain the battery temp, and frequently rely on heaters to maintain battery and cabin temperature.

    So saying BEVs create waste heat too is technically true, but it seriously undersells the scale of difference between the BEV and the ICE.



  • Nah, guillotine is less gruesome than a hanging. Proper guillotine usage, blade falls, head comes offbody is secured, so there isn’t a lot of flailing. The blade itself blocks or stops a lot of the blood from shooting out, you might get a little from the head itself, but it falls into a basket. The victim is facing down, so there is no expressions for the crowd to witness.

    Meanwhile, in a proper hanging, where everything as planned, a whole person drops a few feet, snapping the neck, the body spasms twitches around violently, even if the victim is fully bound. The crowd gets to see the expression and life fade from the victim’s face, it’s whole spectacle. Not to mention there are a lot of ways the hanging can go wrong. If the height is to short, or the rope is new, the neck won’t snap, and the victim does a hangman’s dance for 5 or so minutes as they fight to breath, the brain is still connected to the body, so it’s a very directed and desperate struggle instead of a minute or so of errant electrical pulses.
