An idling gas engine may be annoyingly loud, but that’s the price you pay for having WAY less torque available at a standstill.
The motors have never been the problem, it’s always been the battery. See train engines, they are a diesel generator with electric motors.
This is where history pisses me off. We should have been headlong into battery research after the oil embargoes. Could have been 40 years faster.
I think people forget that petroleum is condensed and distilled solar energy. One gallon of gasoline is the results of years of solar energy.
Spelling
Renewable fuels exist and are used today, but the efficiency and pollution aspects still apply.
oops you posted irrelevant pedantics that verge on misinformation 😧
sure it’s distilled solar energy that cannot be renewed. relevant language highligted. no one “forgets,” this. literally no one. it’s just not relevant to a timespan less than millions of years. cheers! ☀️
Um piss off. It is not irrelevant or misinformation. That is exactly what petroleum is.
You clearly can’t understand a factual statement from an opinion I never said it was good I never said it was bad I just said it was. If you’d bother to take a moment to think about it. You would realize that I was referring to the fact that petroleum is extremely energy dense. For the very reason I stated. That is fundamentally why petroleum has become a successful energy source and why it’s been so difficult to replace.
You’re welcome to point out where I said it was renewable. I think you’re going to have a difficult time finding that statement.
As for being a pedantic ass that’s clearly your territory. A pedantic ass that it likes to put words in other people’s mouths.
Exactly this. Imagine if gas powered motor could recharge in mere 12 hours and run for up to half the distance. Ah, that would be the dream.
And if you and 5 of your neighbors decide to refuel at the same time during peak hours you have a real chance of overloading your neighborhood grid. And your fuel tank is dead in 5 years, replacing which is more than half of your used cars cost.
Everything non-portable uses electric motors from the time the first wire was invented.
I am being serious - can you factually counter those points? I’d like to know the truth of the matter.
When you look at fueleconomy.gov you will see that the furthest a compact ev can go is 149 miles while the furthest a ice compact car can go is 594 miles
https://www.cnbc.com/2023/07/01/why-the-ev-boom-could-put-a-major-strain-on-our-power-grid.html You can read cnbcs article on how the grid is already pretty spread thinn with us already increasing our power demand by almost 3,000% in the last decade without even considering ev charging
https://www.motortrend.com/features/how-long-does-it-take-to-charge-an-ev/
According to motor trend DC charging is the fastest way to charge your EV and it still takes just under two hours Couldn’t find a source that studied how long a ice takes to recharge but considering how ices are currently extremely common you can easily test that yourself and probably already know it’s so quick you don’t even think about it
https://www.caranddriver.com/features/a31875141/electric-car-battery-life/
According to car and driver those lithium ion batteries you mentioned while yes they can last a decade most cars typically stay on the road for give or take 30-35 years and lithium ion batteries are inherently expensive and prone to thermal cascading ie catching fire also full charge and depletion wears the battery down over time
https://www.edmunds.com/electric-car/articles/electric-car-battery-replacement-costs.html According to Edmunds.com the average cost of ev battery replacement costs anywhere from 5,000$ to 15,000$ So what point was made up
I hope you are not talking about battery locomotives.
With overhead wires the train has a practically unlimited battery capacity.
Not really. Battery tech has always been advancing. Even today electric vehicles have barely come up with anything new, battery wise. Everyone wants something better than lithium base. No one can get anything to market.
It advanced at a glacier pace because there was no massive driving force. It only kicked off a bit with cell phones and then in any substantial way with laptops. (Yes, batteries existed before that for different things, but there was no massive driving force.) Now imagine what would have happened if we funded it starting in the 1970s.
Didn’t sodium batteries start getting marketed recently?
Yes, but no one’s even glancing at it for use in vehicles. The one that’s finally getting into production is 70wh/Kg. Not nearly energy dense enough yet for ev’s. Lithium batteries are closer to 300wh/Kg. In other words, they take up 1/4th the space and weight. EV’s are already a thousand pounds heavier than non ev’s and that’s already causing extra tire pollution issues and having to overbuild suspension parts and bearings. Making them another 3,000 pounds heavier than that is just out of the question. Let alone making the space to fit the battery.
Sodium is going to change the world with its power storage capabilities connected to solar. Anyone on like 75% of the planet could 100% live off the electric grid problem free with enough solar panels and a big sodium storage battery.
Oil is honestly an amazing product, chemistry wise there is so much we can do with it and energy wise it’s a extremely concentrated and easily transported form of energy.
Energy wise one liter of oil is equivalent to 10 person working for a day !
I repeat, using one liter of oil is like having 10 “slaves” working for us for a day.
Its easy to see why oil became the base of our modern civilization, and easy to see why we don’t manage to stop using it even though it’s destroying us.
pretty sure most trains are powered by either overhead wires or third rails? considering that urban rail systems are always electrified and those have A LOT of trains.
okay? i’m talking about the world though, so typical for people to just assume america is all that matters lmao
But remember, electric motors also require next to no maintenance and can last for many years of runtime. Pros and cons.
Uh, maintenance is one thing where ICE wins (until very recently, thanks fucktards in car industry). Cars have been generally very easy to work on, with anyone with a toolbox being able to do most their repairs in a shed
This isn’t a function of the engine though right? Electric engines are inherently simpler and should therefore be easier to maintain (putting aside company fuckery)
High voltage is scary as fuck, but also the fact that absolutely everything from doors to gas pedal and chairs are controlled by a computer you need specialized proprietary equipment to investigate.
This is an issue with new ice cars too to be honest
That’s a user-hostile feature, not a property of electric engines. An electric car has far simpler mechanical parts, and the circuitry isn’t very complicated either. It could be made incredibly easy to repair, modify, and upgrade, mostly at home even, if they designed them that way
I’m big into motorcycles and all the electric motorcycles are like 100 lbs more and go through tires like twice a year compared to my gas powered motorcycle changing tires once everyother year and can go fraction of the distance. Idk I want to think electric is the future but with these limits I’m still not too interested. If hydrogen ever comes to motorcycles like Kawasaki, Honda, Yamaha and Suzuki want, I’ll definitely get one of those but I can’t recommend any electric motorcycles right now and before you say anything I would recommend a Surron if you check your welds before you buy those are great commuters but probably not a motorcycle.
Sorry for not being clear, I change tires on my gas powered commuter motorcycle about once every two years. Electric motorcycles seem to go through tires much faster it was explained to me that the bikes are heavier and most tires aren’t designed for electric motorcycles.
that just sounds like too much throttle because you’re not familiar with the extra torque from take off.
nothing to do with a little extra weight.
my last two bikes were over 1L, with a curb weight of something like 280kg, maybe. 45kg extra in batteries is like a child or a big dog. it’s not much.
not enough to double your wear rate.
The torque off the start is so much higher in EVs vs. ICE. I’m not sure from u/blindbunny 's post if they’ve ridden an EV motorcyle. I’m pretty sure they haven’t owned one. They sound like an ICE shill. My bicycle’s torque off the start is pretty low, and dependent on this old school “neuro-musculo-skeletal” system. It’s kinda jankety, but I’m too cheap to upgrade.
I wish I was a shill I’d probably have more money to buy more motorcycles. I’ve rode a Surron bee? and a Stark VARG and I kinda like how quite they are especially dual sporting. But it takes almost half a day to charge the Stark VARG and the longest I’ve rode a Surron was about ~20 miles before it needed to charge.
Many motorcycles (not bicycles, those are irrelevant to the comparison) already have more torque off the line than the available traction can handle, so that benefit from electric motors is less critical. The wear is a concern because motorcycles are already more sensitive to tire wear than cars, and simply switching to a harder compound to account for the extra weight has other ramifications that are far less severe in electric cars.
And over time power density in batteries has increased. So far.

People just won’t stop telling you this, it seems. ;-)

compared to my gas powered motorcycle changing tires twice a year
…so, you’re changing tires less on an electric motorcycle? I don’t see the issue
Yeah, a general “electric vs. gas” comparison which elides the two big disadvantages of electric in familiar applications (which aren’t to be found in the motor) seems slightly subpar for xkcd. It’s valid from a certain narrow engineering perspective but not too helpful if what you’re thinking about is motorcycles.
If fossil fuels were so easy to give up we’d have done it by now.
On one hand, electric motors […]
On the other hand, electric motors […]
Typo?
Gas engine makes good noises. Checkmate.
Think of the most annoying sound you know. Whether it’s country music, rap, lawnmower before 8am on sat, etc that is your “good noises” sound like.
There is a huge difference between a finely tuned V8 with an appropriate muffler versus a gas lawnmower, but to each there own.
Great username btw
Mr. Monkey subjectively your finely tuned v8 sounds like a 400lb basement dwelling gorilla someone has fed laxatives and recorded from the bottom of a well used coachella porta potty.
Think of the nicest sound you know. A well-tuned instrument performing a delicate melody, a passionate singer performing their heart out, a cacophony of songbirds. That’s what my good noises sound like when done right.
Obviously nobody wants to hear a fart can Honda Civic at 4am, but a fantastically engineered Italian V10 has its own melody that can’t really be replicated otherwise. These examples will be missed, and the survivors will be sought after like a vintage violin.
So total fucking silence? I swear to God it’s like the call to stroke each other off for you guys.
It’s incredible how certain people are conditioned to think the sound of a gas motor and shifting because your puny motor is out of optimal torque and rpm range are manly.
I’m a car guy and far from manly. I drive a loud annoying stick shift because it’s fun and life is too short to be bored while driving.
The ioniq 5 N has that covered, evidently: https://youtu.be/DSIguemKIbQ?si=Do2diTJm8-_Hb9Ro
Or playing cards in the wheels
When accelerating my Leaf makes a “woooooooooooOOOOOOOOP” noise I’ve seen described as the “UFO sound”
Tbh I like it a lot more than the vroom of even my motorcycle cuz it’s funny
Yeah, but does it make Oscar Winner Hans Zimmer kind of noises? https://www.bmw.com/en/magazine/innovation/hans-zimmer-individual-drive-sounds-as-identity-for-electric-vehicles.html
I don’t see how making noise is good. I live in a street that doesn’t get much traffic, but even one car is loud enough to be bothering.
I don’t want to pause my music and conversations just because someone decided that vroom vroom sounds were more important than me hearing literally anything else.
Even more that noise pollution is definitely a thing, and affect both mental health and physical one.
Vehicles making noise actually is good, for pedestrians’ sake, but yeah ICE vehicles make far more than they need to. Some (? many? I’m not sure how standard it is) electric vehicles make a sort of beeping sound for that reason.
If you’re in an area where pedestrians may be crossing the road, traffic should be slow enough to use permeable brick pavers, which increase road noise, help with rainwater drainage, and add a little green to the road if find right.
The majority of sound for cars are not the motor but the wheels compressing air, after I think 50kph, the sound of an ev or a ic is basically the same.
