1:37 Minor correction: The fuel-air mixture is specific to gasoline engines only. In diesel engines, air is compressed first, and then diesel is sprayed onto it. This method allows for greater air compression without the risk of the mixture self-igniting, resulting in more thermal efficiency which can yield more power from the same amount of fuel. This is one of the reasons diesel engines are more efficient than gasoline ones.
That's right. Only one small correction: diesel creates more power for the same amount of ENERGY, not necessarily fuel, since diesel and gasoline have different calorific values (energy per quilogram of fuel). To make a complete comparison, you would have to take into account the density and calorific value. Also one would need to specify if he is comparing on a mass base or volume base.
EVs are extremely capable, they still need work done to improve and require more efficient ways of getting that energy. Everyone said the same about combustion cars when they came out and look where they are now.
another key point that i think was missed in this video the EVs are usually powered by electricity thats said to be generated mostly by coal power plants..and people say thats equivalent to an internal combustion engine run car...what most people miss out is that the processes used to convert fuel in powerplants are much more efficient than an internal combustion engine
There is no free lunch here. Any time you do something, there is a consequence. It's pretty clear that fossil fuels have no future, and we need alternatives. If you really care, drive less. Ride your bike and use public transportation.
@@mithunbobade1 that's a different point. what you are referring to is the source of the energy. what this commenter is saying is that even if the energy is not clean (coming from combustion) the process of generating the energy at a plant is more efficient than inside a car, since the cars are so inefficient (the point mentioned at 2:34 in the video)
That is true but the problem is getting electricity from the power plant to your car. You first have to carry it over long distances through wires, then there are a lot of inefficiencies in both the charging and discharging process, thus bringing the overall efficiency down. I don't know what the numbers are and I suppose it depends on the situation, but it's nevertheless a thing worth remembering
@@sebasbot01 in the early days of electricity, Thomas Edison advocated DC power transmission, and Nicola Tesla advocated AC. Tesla was right; AC is much more efficient for transmission over long distances. How about digging up petroleum from the Middle East and shipping it via tanker across the ocean, refining it, then driving it around in trucks all over the country? It's like email vs. the pony express.
One concern that wasn't mentioned is that the manufacturing process of EVs itself is incredibly polluting (primarily the batteries), so depending on how long the EV is used for + where its energy comes from (i.e., renewable sources or not) EVs could end up being only slightly better (if at all) than a combustion engine. But hopefully we find solutions to those issues soon.
Yes, both EV and gasoline vehicle manufacturing processes will create pollution. But, nearly all research shows that even when factoring in the battery, and assuming the grid is driven by mostly fossil fuels (both of which will change), EVs right now have a smaller carbon footprint than combustion engines. Plus, renewables and battery tech are some of the fastest growing research fields on earth right now. I wouldn't lose hope yet! People all around the world on working on these issues right now.
unless your car gets 120 mpg without somehow breaking epa rules (a more efficient engine generally results in worse emissions) then your gas car doesnt stand a chance.
Im in my late 20s but can picture myself in 2077 being an 80 year old, walking on the road so silent and devoid of all vehicular sounds thanks to EVs. I don't know if I'm gonna live to see a utopia or a dystopia. Anyways this comment will still be there regardless of me.
Most animations on this channel’s videos are very well made, but this one specially is just so fluid and charming! Thank you for making the amazing content you do free for everyone to see ❤
This video forgot to mention one important aspect. The production of big lithium-ion batteries, which are commonly used in EVs, is resource-intensive and has very negative environmental impacts.
There is no free lunch here. Any time you do something, there is a consequence. It's pretty clear that fossil fuels have no future, and we need alternatives. If you really care, drive less. Ride your bike and use public transportation.
Very negative environmental impact that is about the same as driving 25 000 km with an ICE car. Most cars drive well over 100 000 km in their lifetime. Then there is also the fact that those environmental impacts are isolated to specific mining locations, instead of pumping it into the atmosphere.
You’re forgetting once that lithium is mined it’s around for a long time, same can’t be said for a tank of gas. Obviously, mining operations have to change anyway regardless

As a technician, I watch this video with the same level of curiosity and wonder as i watch other TedEd's video about biology, history, mythology and riddles.
This was one of my favorite TedEd videos ever. I find everything easy to understand and now I feel a little more knowledgeable about the things I drive every day!
It’s very well explained. You just forgot to mention that, in electrical cars, it’s the construction of the batteries, solar panels, etc that releases lots of co2
That is obvious, but probably wasn't mentioned because ICE cars and their thousands of parts also release lots of CO2 during at the manufacturing phase.
There is nothing wrong with supporting EVs. But supporting something for the sake of supporting it it's just blatant advertising. It's obvious TED-ED depicts EVs as only superior because it's propaganda.

@@theWZZA so what is that virtually NO ONE is talking about the fact that we’ll be facing the SAME PROBLEM AS fossil fuel companies since the batteries and energy delivery systems needed are themselves limited like fossil fuels making the problem redundant and unnecessarily more costly to implement That’s so what genius.
Maybe make the next video on explaining the most efficient vehicle on this planet which is the bicycle. Which is also the most greener of all vehicles because it relies on your muscles to move.
If you are going to do that then the most efficient is walk/run from point a to b…. There’s a reason we don’t do that tho… it’s extremely inefficient which defeats the purpose… Are you going to walk an hour and back to work everyday? Are you going to walk for 5months to visit family across the country? That’s if you even survive that…
I love the work you guys/gals do in entertaining and educating, and this video is no exception. I only wish you had also mentioned highway efficiency comparisons of electric and ICE vehicles. Electric cars are phenomenal for city driving, but consume more and more energy as the speed to maintain increases. It is my understanding that ICE vehicles are technically more efficient for long distance/higher speed driving. I would love to see you guys make a video dedicated to that.
EVs remain more efficient for long distance/higher speed driving. The issue with them becomes convenience. The main two advantages ICEs have over EVs is power density, and portability - both of these become significant factors when distance or loads are increased,
@@Garfie489 Could you please provide me with some kind of source? I honestly forget where I learned my understanding from, and it may very well be wrong/outdated. Thanks for the reply!
@@peacefultreasure8497 EVs are always way more efficient than ICEs, the range of efficiency was said in the video. But, ICEs (except hybrids) are so bad at low speeds that it makes us talk more about it. That's it.
@@peacefultreasure8497Efficiency: EVs can typically achieve efficiency ratings of around 3 to 4 miles per kilowatt-hour (kWh) on highways. This means they can travel 3 to 4 miles for every kWh of electricity consumed.Range: Many modern EVs offer highway ranges of 200 to 300 miles or more on a single charge. Some high-end models can even exceed 300 miles.
Huh. The method described at the beginning is what I try to do whenever it's possible. It just feels instinctively right. I know nothing about machinery. Sadly, it's hard to do that when you live in a city where cars are constantly stuck in traffic jams.
A small footnote on EV energy / carbon efficiency: Even if an EV is charged with electricity from a fossil fuel power plant like coal or natural gas, the carbon output per mile is lower than that of internal combustion engines, as most powerplants are vastly more efficient (turning a higher % of fuel to energy) than a regular fuel-powered car's engine. And yes this accounts for conversion losses with charging / discharging the battery.
As mentioned in the video, a normal combustion engine has a lot of moving parts. Each interaction is a point of friction and therefore loss of energy. Another thing to keep in mind is that they require cooling, oiling, and quality of life accessories. That means pumps to move various liquids around. Coolant and oil to keep the engine from destroying itself. Hydraulic fluids for power steering and breaking. Even your AC requires a pump and fan to cool your cabin. These are all leeches on power that would otherwise go towards the wheels. If you ever wonder why we have turbochargers instead of superchargers, this is the main reason why. Supers are driven by a belt connected to the engine, another power leech. You still gain more power than is lost, but worse than a turbo. Turbos, on the other hand, are driven by the exhaust of the engine, energy that would've been gone out of the tailpipe. There is still a small loss in power from a turbo, but that's mostly because it requires the engine to do a little bit more work to push exhaust through the turbo. For both chargers, the reason why you gain more power than is lost is because they compress the incoming air for the engine. More air means more fuel and better combustion.
@@drayke8886 He is talking about the engine alone. You only have maximum power to do all those stuff, as they are powered by the engine. Its why some vehicles need to turn off AC when they run up a steep hill.
@@HIFLY01the effects are not the same. AC in an internal combustion engine car leeches power from the engine, meaning less power for the wheels. AC in EV's leeches power from the battery, this does not affect the amount of power available to the wheels. It only affects the drain on the battery. It might even not be the same battery that is affected, I don't know. Anyway, you get the point. HP going to the wheels stays the same in EV's. Correct me if I'm wrong.
@@GierJoost true but unless you're driving a super old car it shouldn't have that much of an affect. Is the difference between 120 vs 110 going to matter? Probably not for most people. Your engine will try to increase its power and unless you're somehow always running at max rpms it shouldn't be an issue. Hauling a trailer or something heavy is one thing but doesn't really matter for most of the population. Not sure what year the other guy lives in because if a car cant go up a hill without an extra 3-10hp, it probably isn't the compressors fault
A very subtle way to inception into a young petrolhead's mind about the cool factor of EVs. Bravo! Some good psychological thought went into the creation of this video. 👏 Hope it works for the best. In the meantime, I continue reving up my efficient agricultural diesel. 🙏😊
I maybe get that’s it’s more efficient with fuel, but it’s goddamn annoying when you’re driving behind such a person on a pretty busy road 😅 like just put on cruise control!
You should know that the reason EV's haven't surpassed fossil fuel powered cars isn't because of their speed or price, but rather because how long it takes to charge them. If a fuel powered car is on empty it may take as short as 5 minutes to refuel, but if an EV's battery is drained it could take hours to fully charge. I'm not an electrical engineer, but it's my understanding that the technology simply doesn't exist yet to make EV batteries charge faster.
@@catdogmousecheeseI mean my family just charge our electric car at home nightly. Saved 100-200 dollars a month and only had to go to a charging station two times in one year. Unless you are going on a road trip or from city to city, electric cars are just more convenient
@@catdogmousecheese Not necessarily. Highly depends on where you are charging your EV. At home, sure - depending on where you live you only have a low voltage to fuel your car, but that shouldn’t be concerning as you typically charge over night. At gas stations, at least in Germany, there are most of the time super chargers, which let you charge your EV with up to 250kW. In my experience the charging process often only takes about 15 Minutes to get from 15 to 90%. That time is quite practical to get to the restroom, get something to eat or just walk around and relax your feet.
@@catdogmousecheese The technology is still in development. I'm particularly excited for when ev's have solid state batteries like in this video: th-cam.com/users/shortsORfGt4Nh7hs?si=ZkQRpW0VMJ9idXP7
Fun fact: Combustion engines also have "regenerative braking" of their own. More percisely during the slowing down without brakes (like in glide) allows for a technique known as "engine braking". When driver shifts to lower gear when RPMs are low the engine itself acts as a brake.
I think this video is too-simplfied, where some statements are false. Yes, in non-turbo gas cars, the gas pedal directly controls air intake valve into the carburetor. The air intake is also connected with the fuel intake using venturi valve - meaning more air -> higher air pressure -> higher gas intake. A lot of cars today use turbo and turbodiesel, as you said, you have direct injection, no carburetor, air coming from turbo... much more complicated system and much bigger involvement of computer to create this air and fuel mixture. Few other things to mention about the video: - There are 3 cylinder engines now, very efficient - We cannot talk about EV, without mentioning the power to weight ratio of gas compared to batteries. Every EV that can take highways, with real (not advertised) range of 500km has like 2.5 tonnes because of batteries. Cars are almost like tanks, having much more energy in car accidents.
The problem with continuous pulse and glide model is that when releasing the pedal engine braking will start and decrease the efficiency of glide. I don’t know if modern automatic cars allow coasting with disengaging gears
depends how fast/what gear you're going, but if it's low enough RPM the engine braking effect will be minimal, and still more efficient. Low RPM is better for gas mileage anyway, and automatic cars tend to favor driving in higher gear if possible for that reason. But you can also always put it in neutral if you're gliding fast enough or downhill at all, or use the clutch.
the video did mention where the source of the electricity matters, but what about the metals you needed to make those batteries. might be a good video idea
Its a first step for a greener energy in the future. why dont you think in a positive side? industrial factories are providing the EV industry now. It will change but it will take some time to adapt. Majority of our energy relies still in fossil fuels tho which is bad.
@@janstefanflores2624Why don't you think of the realistic side and realize that spending money on public transportation will also help with this and other problems?
@@kakahass8845 ok what im trying to see is a bigger picture that we can slowly transition from fossil fuels to EV. I understand your point where "those things are made of". Apologies mate but we need some emissions to start a greener energy.
@@janstefanflores2624That is not my point at all my point is that public transportation is a better solution than EVs and probably easier to implement too.
There’s a ted Ed talk where someone said that it takes 60 million tons of c02 to make a battery for one ev car. All that mining for lithium and the fact that you can’t recycle a battery and over time the battery becomes weaker until you replace it with another one that took 60 million tons of c02 goes to show you just how unclean evs really are
There should me more videos like this, they are really interresting and tell us about the real power off innovation. Just like a gas stove vs an induction one, the first one has a efficiency of 40% (most of the energy is dispersed in the air instead of cooking your food) meanwhile the induction stove has an efficiency of 90%. Even if the gas cost less, the induction stove is superior, by efficiency, the renewable energy source, for a civilization view point (so in the long run) che choice is obvious, even if now it's more pricy because of our economics, one day will also be the best choice by a economic view.
People like to own their own house and go to and from when they please as they should be able to. Once you move outside the city you'll realize its not very practical especially for trains. Buses are one thing for larger towns but not every city has enough money to pay for them
@@HIFLY01 The problem is - in this economy, no one is owning their own homes. They've been bought up by the landlording class. Plus, with a well-planned city and transportation system, you can indeed get anywhere you want whenever you please even with a public transit. It's also far more cheaper to take the train than the cost you need to maintain a car, meaning that trains promote more social mobility. America used to have very good public transit until the auto lobby killed it.
@@scythal maintaining a car isn't that expensive unless you go to the mechanic often. I've checked and at least personally for me its either the same or higher cost to take the public transportation system to my nearest city and that is just the train itself. Adding buses makes owning a car cheaper and this is with my old 99 Subaru with around 20mpg. More modern cars like a Hyundai Elantra get closer to 38 so I could drive to the city with 1.5 gallons of gas. Thats less than $6 at the current price of gas vs $6.75 for a 1 way ticket via train. I'd still need to go to the train station by bus and still need to take the bus from the station to my destination 4 times per trip. Yeah if you lived 3 blocks from your work in the city it probably would be cheaper but a lot of states like Illinois tax everyone for public transportation thats used in Chicago and thats not fair to us. I don't live in the Chicago and 9 million others also dont but we shouldn't have to prove to a city and get nothing in return. If people want to do that, set up donation boxes

EVs require regular charging of their batteries. Meaning their emission profile is only as clean as the electric utility they plug into.”

Finally I’ve come across a topic that I know inside out(literally) and I’ve learned one thing today, TED is not all that accurate with their information and it’s so so basic it didn’t even scratch off the oxide layer of the metal. I can’t imagine how many mistakes it has in other topics.
4:20 I can’t disagree with this more. Most parts in a combustion car are replaced as an assembly nowadays so you really don’t have that many parts. Also please pop the hood of an electric car, and take a look at the wires and cooling systems, I had to replace the rubber bushings of motor mounts of two experimental 2025 Audi SUVs because the engineers think the original ones are too soft, and I had to drop the whole subframe to replace 3 rubber bushings.
i think i know the issue of that car aside from the bushings, it's an Audi(VW group) made. The company that's pushing electrification of their vehicles so hard because they got caught cheating their emissions test lmao
Cars are incredibly complex machines. This video barely brushed over how the engine works. It’s crazy all the stuff we use daily and that we owe to so many smart people.
As if manufacturing and operating a ICE vehicle doesn't? No free lunch. If you really care, ride your bike, the bus, the train whenever it is possible.
@@oussamalekbal6544 yes they are, if everyone had cars we'd all be stuck in near-permanent traffic gridlock. Trains and buses are far more efficient for moving masses of people at once.
Video’s title: This is what happens when you hit the gas. Video’s thumbnail: How does a car engine work? Actual video: EVs and regenerative braking and stuff. I’m used to getting clickbaited, but not usually by TED.
Very good explaination of the driving strategy to exploit the engine efficiency. On the other hand this video contains some misleading information. You cannot compare electric energy of the battery and chemical energy of the fuel. A thermodynamic machine is needed to convert chemical energy to mechanical work, while electric energy is already mechanical energy stored as electric potential in the battery. Hence the comparison battery/fuel tank is not fair and misleading. I expected a better content form TED, especially on the scientific side. No one is going to get advantage from erroneous informations.
There is no free lunch here. Any time you do something, there is a consequence. It's pretty clear that fossil fuels have no future, and we need alternatives. If you really care, drive less. Ride your bike and use public transportation. Merely offering whataboutism doesn't accomplish anything.
@@cott299 Don't defend the blatant EV bias in the video. It argues that EVs have lower emissions than cars with combustion engines. It doesn't matter to the environment that the electric car itself generates very little emissions if it's just offset by the emissions of the production of its electricity.
EVs are definitely great! they are a part of our solution going forward. Developments like battery recycling (which already exists in some form) will only add onto the benefits of EVs.
i was recently thinking about this topic!! i was thinking about how would i explain cars to someone who has never seen one, and this video puts it so well 😊
I love it how the wok always fail to mention the reality of EV when discussing them and only talk about the good. First of all, nobody seems to mention the fact of not only how expensive it is to build the batteries for these vehicles, but also how these rare metals are mined. Second, when a gas engine reaches even if life, it can be recycled or rebuilt. When a battery reaches end of life, what happens to it? Nothing. Exactly. Because nobody has figured out how to recycle them. They are even more expensive to recycle. Finally, if you’re unlucky enough to have your car on fire, good luck putting that EV fire out. They have become the firefighter’s worst nightmare. When you’re trying to educate people, you should do a good job of showing all the facts and not just the ones that please your narrative. Anyone that’s still considering buying a EV, should do the research about the facts I stated above. Yes EV are the future, but as of now, that future is not here and the technology is still new and needs more work.
"Because nobody has figured out how to recycle them." - multiple companies will offer to recycle them. Thats before you consider many car batteries can be reused without modification as batteries in other uses. EVs catch fire less than 60x as often as a comparable ICE vehicle. Sure its not great when they do catch fire, but having to deal with 60 ICE fires aint great either. The "facts" you mentioned are common knowledge. People know EVs cost more, but also cost less to run - thats literally their major selling point.
@@Garfie489 first, go read about how the resources needed to build the batteries are mined and where and what type of labor. Second, as far as recycling goes, have you ever tried to recycle a solar panel or a EV battery? The technology is not there. Anyone that tells you that they are recycling it, are lying to you. Make a simple call to the company that manages your normal waste and ask them about it. Then call your local city and ask them about it and see how much they know and what I formation you get. I have done my research on this as well as from personal experience. As far as the cost goes, with the rise in electric bills, it is already just as expensive as gas depending where you live. Many car companies offer free charging for 2-3 years that may seem like a cost cutting strategy, but eventually you will have to pay for the charges and believe me with anything else, once the demand goes up, so will the price of electricity. Also the battery is another cost issue. It’s a known fact that the most expensive part of a EV is the battery. Once that battery is damaged or reaches end of life, (which nobody really knows when that is since EV mass production is pretty new), the cost of replacing it is outrageous. Often times it costs more than the car itself is worth at the time. As far as fires go, most of the car fires that I’m taking about are during major disasters such as the ones we saw in Hawaii. When a fire ravages through town, all cars regardless of engine type will burn. I’m not against EV. I think it’s the future of travel, but right now, we don’t have the infrastructure, the ability to properly recycle the batteries, or even any idea how long they last and how expensive they are to repair. That’s not to mention the fact that it takes so long to charge a EV. Imagine if tomorrow half your city had EV, how long would you be waiting in line at a charging station to be able to charge and go? What about travel? Assume you want to go from Los Angeles to Las Vegas which is about a 240 mile trip. What would happen is highway 15 gets backed up or if there’s an accident? How will you be able to charge your car? Will you even make it to your destination? How about cross country drives? This was the same issue we had back when the automobile was first introduced. It wasn’t until the late 40’s and 50’s when they started to have gas stations all over where people weee able to travel long distances which is when the highway systems were built to accommodate that. It took decades not few years. It took decades to build engines that were more reliant, inexpensive, and better gas mileage. Right now we are at the cross roads of where horse and buggy meets the automobile was 100 years ago. We need to invest time and money to improve and eventually make that change.
@@WWTormentor i regularly recycle the same batteries as used in EV's. For me, its as simple as putting it in the correct bin - because there are multiple companies out there that do exactly that. My "local city" has one such bin at our local recycling center. Its really not that hard - your "research" likely doesnt meet the standard of what research actually is, given it can be disproven by a simple Google - nevermind this being a part of my PhD. It costs pennies to "refuel" an EV, whereas it costs a days wages to do the same with an ICE vehicle. They are not comparable. Also major events like forest fires wouldnt affect the average that much, because as you say - both burn. Thus the average is the same for both - yet ICE vehicles have a rate 60x higher than that of EVs per vehicle sold.... which actually suggests the rate of ICE fires is actually worse. The majority of people drive less than 50 miles a day. If you have an EV with 250 miles of range, you may only need to plug it in once a week whilst at home overnight. The majority of EV owners never have to visit anywhere to recharge - so if half the population had one, itd be no issue at all in terms of finding a charging station.
Nobody seems to be talking about where we're going to get all of this lithium and nickel from needed in these batteries, there are only so many potential mining sites.
Wow. this TED-ED video quickly showed so much bias to electric vehicles. As an education channel, please stay as neutral as possible, or at least appear as neutral as possible. Of course, that doesn't mean you can't take a side in a debate but at least bring up both facts on sides to make a conclusion instead of blatantly favouring one out of the blue (Like did you mention the environmental cost of rare metals in EVs?)
For the rest of the non-US world, 100 gallons are 378 liters, and 81 miles per gallon means 34.4 km per liters.
Which is equivalent to 2.9 l/100km. Quite impressive!
I'm trying this out tomorrow

@@MatejaMaricI can only get down to 4,7 I think😂
1:37 Minor correction: The fuel-air mixture is specific to gasoline engines only. In diesel engines, air is compressed first, and then diesel is sprayed onto it. This method allows for greater air compression without the risk of the mixture self-igniting, resulting in more thermal efficiency which can yield more power from the same amount of fuel. This is one of the reasons diesel engines are more efficient than gasoline ones.
That's right. Only one small correction: diesel creates more power for the same amount of ENERGY, not necessarily fuel, since diesel and gasoline have different calorific values (energy per quilogram of fuel).
To make a complete comparison, you would have to take into account the density and calorific value. Also one would need to specify if he is comparing on a mass base or volume base.

How about digging up petroleum from the Middle East and shipping it via tanker across the ocean, refining it, then driving it around in trucks all over the country? It's like email vs. the pony express.
One concern that wasn't mentioned is that the manufacturing process of EVs itself is incredibly polluting (primarily the batteries), so depending on how long the EV is used for + where its energy comes from (i.e., renewable sources or not) EVs could end up being only slightly better (if at all) than a combustion engine. But hopefully we find solutions to those issues soon.
Yes, both EV and gasoline vehicle manufacturing processes will create pollution. But, nearly all research shows that even when factoring in the battery, and assuming the grid is driven by mostly fossil fuels (both of which will change), EVs right now have a smaller carbon footprint than combustion engines. Plus, renewables and battery tech are some of the fastest growing research fields on earth right now. I wouldn't lose hope yet! People all around the world on working on these issues right now.
unless your car gets 120 mpg without somehow breaking epa rules (a more efficient engine generally results in worse emissions) then your gas car doesnt stand a chance.

This video forgot to mention one important aspect. The production of big lithium-ion batteries, which are commonly used in EVs, is resource-intensive and has very negative environmental impacts.
There is no free lunch here. Any time you do something, there is a consequence. It's pretty clear that fossil fuels have no future, and we need alternatives. If you really care, drive less. Ride your bike and use public transportation.
Very negative environmental impact that is about the same as driving 25 000 km with an ICE car.
Most cars drive well over 100 000 km in their lifetime.
Then there is also the fact that those environmental impacts are isolated to specific mining locations, instead of pumping it into the atmosphere.
You’re forgetting once that lithium is mined it’s around for a long time, same can’t be said for a tank of gas. Obviously, mining operations have to change anyway regardless

Ted Ed videos are always so informative and well made ❤
I love the work you guys/gals do in entertaining and educating, and this video is no exception. I only wish you had also mentioned highway efficiency comparisons of electric and ICE vehicles.
Electric cars are phenomenal for city driving, but consume more and more energy as the speed to maintain increases. It is my understanding that ICE vehicles are technically more efficient for long distance/higher speed driving.
I would love to see you guys make a video dedicated to that.
EVs remain more efficient for long distance/higher speed driving.
The issue with them becomes convenience. The main two advantages ICEs have over EVs is power density, and portability - both of these become significant factors when distance or loads are increased,
@@Garfie489 Could you please provide me with some kind of source? I honestly forget where I learned my understanding from, and it may very well be wrong/outdated. Thanks for the reply!
@@peacefultreasure8497 EVs are always way more efficient than ICEs, the range of efficiency was said in the video. But, ICEs (except hybrids) are so bad at low speeds that it makes us talk more about it. That's it.
@@peacefultreasure8497Efficiency: EVs can typically achieve efficiency ratings of around 3 to 4 miles per kilowatt-hour (kWh) on highways. This means they can travel 3 to 4 miles for every kWh of electricity consumed.Range: Many modern EVs offer highway ranges of 200 to 300 miles or more on a single charge. Some high-end models can even exceed 300 miles.
Huh. The method described at the beginning is what I try to do whenever it's possible. It just feels instinctively right. I know nothing about machinery.
Sadly, it's hard to do that when you live in a city where cars are constantly stuck in traffic jams.
A small footnote on EV energy / carbon efficiency: Even if an EV is charged with electricity from a fossil fuel power plant like coal or natural gas, the carbon output per mile is lower than that of internal combustion engines, as most powerplants are vastly more efficient (turning a higher % of fuel to energy) than a regular fuel-powered car's engine.
And yes this accounts for conversion losses with charging / discharging the battery.
If only tho that worked for planes but we will get there
Damn the animations are really good! The incorporation of Synthwave elements into a car video is just perfect!
As mentioned in the video, a normal combustion engine has a lot of moving parts. Each interaction is a point of friction and therefore loss of energy. Another thing to keep in mind is that they require cooling, oiling, and quality of life accessories. That means pumps to move various liquids around. Coolant and oil to keep the engine from destroying itself. Hydraulic fluids for power steering and breaking. Even your AC requires a pump and fan to cool your cabin. These are all leeches on power that would otherwise go towards the wheels. If you ever wonder why we have turbochargers instead of superchargers, this is the main reason why. Supers are driven by a belt connected to the engine, another power leech. You still gain more power than is lost, but worse than a turbo. Turbos, on the other hand, are driven by the exhaust of the engine, energy that would've been gone out of the tailpipe. There is still a small loss in power from a turbo, but that's mostly because it requires the engine to do a little bit more work to push exhaust through the turbo. For both chargers, the reason why you gain more power than is lost is because they compress the incoming air for the engine. More air means more fuel and better combustion.
Never seen EV without cooling, AC, steering or breaks.
@@drayke8886 He is talking about the engine alone. You only have maximum power to do all those stuff, as they are powered by the engine. Its why some vehicles need to turn off AC when they run up a steep hill.
@@resugram_YT thats the same exact thing for EVs...
@@HIFLY01the effects are not the same. AC in an internal combustion engine car leeches power from the engine, meaning less power for the wheels. AC in EV's leeches power from the battery, this does not affect the amount of power available to the wheels. It only affects the drain on the battery. It might even not be the same battery that is affected, I don't know. Anyway, you get the point. HP going to the wheels stays the same in EV's. Correct me if I'm wrong.
@@GierJoost true but unless you're driving a super old car it shouldn't have that much of an affect. Is the difference between 120 vs 110 going to matter? Probably not for most people. Your engine will try to increase its power and unless you're somehow always running at max rpms it shouldn't be an issue. Hauling a trailer or something heavy is one thing but doesn't really matter for most of the population. Not sure what year the other guy lives in because if a car cant go up a hill without an extra 3-10hp, it probably isn't the compressors fault

If you guys made a movie just based off learning and different montages of artists I'd pay to watch it so many times.
I might be an auto mechanic after college, but I'm really excited about EV's. I would love to have one.
You should know that the reason EV's haven't surpassed fossil fuel powered cars isn't because of their speed or price, but rather because how long it takes to charge them. If a fuel powered car is on empty it may take as short as 5 minutes to refuel, but if an EV's battery is drained it could take hours to fully charge. I'm not an electrical engineer, but it's my understanding that the technology simply doesn't exist yet to make EV batteries charge faster.
@@catdogmousecheeseI mean my family just charge our electric car at home nightly. Saved 100-200 dollars a month and only had to go to a charging station two times in one year. Unless you are going on a road trip or from city to city, electric cars are just more convenient
@@catdogmousecheese Not necessarily. Highly depends on where you are charging your EV. At home, sure - depending on where you live you only have a low voltage to fuel your car, but that shouldn’t be concerning as you typically charge over night. At gas stations, at least in Germany, there are most of the time super chargers, which let you charge your EV with up to 250kW. In my experience the charging process often only takes about 15 Minutes to get from 15 to 90%. That time is quite practical to get to the restroom, get something to eat or just walk around and relax your feet.
being a auto mechanic doesnt mean to work only with one type of engine, at least in my opinion
@@catdogmousecheese The technology is still in development. I'm particularly excited for when ev's have solid state batteries like in this video:
th-cam.com/users/shortsORfGt4Nh7hs?si=ZkQRpW0VMJ9idXP7
Fun fact: Combustion engines also have "regenerative braking" of their own. More percisely during the slowing down without brakes (like in glide) allows for a technique known as "engine braking". When driver shifts to lower gear when RPMs are low the engine itself acts as a brake.
Me, a studied Engineer working at Volkswagen: "Yeah, how DOES an engine work?"
Im more suprised ted-ed didn't have a video for this already... Nice work!
2:09 since you are talking about a disesl engine, gas pedal does not control the amount of air entering the cylinder
I think this video is too-simplfied, where some statements are false. Yes, in non-turbo gas cars, the gas pedal directly controls air intake valve into the carburetor. The air intake is also connected with the fuel intake using venturi valve - meaning more air -> higher air pressure -> higher gas intake.
A lot of cars today use turbo and turbodiesel, as you said, you have direct injection, no carburetor, air coming from turbo... much more complicated system and much bigger involvement of computer to create this air and fuel mixture.
Few other things to mention about the video:
- There are 3 cylinder engines now, very efficient
- We cannot talk about EV, without mentioning the power to weight ratio of gas compared to batteries. Every EV that can take highways, with real (not advertised) range of 500km has like 2.5 tonnes because of batteries. Cars are almost like tanks, having much more energy in car accidents.
Please do more animated videos about cars!!! This was awesome.
The problem with continuous pulse and glide model is that when releasing the pedal engine braking will start and decrease the efficiency of glide. I don’t know if modern automatic cars allow coasting with disengaging gears
*manual user has entered the chat*
So use the clutch?...
depends how fast/what gear you're going, but if it's low enough RPM the engine braking effect will be minimal, and still more efficient. Low RPM is better for gas mileage anyway, and automatic cars tend to favor driving in higher gear if possible for that reason. But you can also always put it in neutral if you're gliding fast enough or downhill at all, or use the clutch.
The music for this one was awesome.

This video is just great, I have never imagined this process that much visually, it is very enjoyable :) thanks.
There should me more videos like this, they are really interresting and tell us about the real power off innovation. Just like a gas stove vs an induction one, the first one has a efficiency of 40% (most of the energy is dispersed in the air instead of cooking your food) meanwhile the induction stove has an efficiency of 90%. Even if the gas cost less, the induction stove is superior, by efficiency, the renewable energy source, for a civilization view point (so in the long run) che choice is obvious, even if now it's more pricy because of our economics, one day will also be the best choice by a economic view.

@@scythal maintaining a car isn't that expensive unless you go to the mechanic often. I've checked and at least personally for me its either the same or higher cost to take the public transportation system to my nearest city and that is just the train itself. Adding buses makes owning a car cheaper and this is with my old 99 Subaru with around 20mpg. More modern cars like a Hyundai Elantra get closer to 38 so I could drive to the city with 1.5 gallons of gas. Thats less than $6 at the current price of gas vs $6.75 for a 1 way ticket via train.
I'd still need to go to the train station by bus and still need to take the bus from the station to my destination 4 times per trip.

Very good explaination of the driving strategy to exploit the engine efficiency. On the other hand this video contains some misleading information. You cannot compare electric energy of the battery and chemical energy of the fuel. A thermodynamic machine is needed to convert chemical energy to mechanical work, while electric energy is already mechanical energy stored as electric potential in the battery. Hence the comparison battery/fuel tank is not fair and misleading. I expected a better content form TED, especially on the scientific side. No one is going to get advantage from erroneous informations.

You should do a video or at least look up rare earth mineral mining to make them batteries. See if they're as green as you think.

@@cott299 Don't defend the blatant EV bias in the video. It argues that EVs have lower emissions than cars with combustion engines.

EVs are definitely great! they are a part of our solution going forward. Developments like battery recycling (which already exists in some form) will only add onto the benefits of EVs.
i was recently thinking about this topic!! i was thinking about how would i explain cars to someone who has never seen one, and this video puts it so well 😊
I love it how the wok always fail to mention the reality of EV when discussing them and only talk about the good.
First of all, nobody seems to mention the fact of not only how expensive it is to build the batteries for these vehicles, but also how these rare metals are mined.
Second, when a gas engine reaches even if life, it can be recycled or rebuilt. When a battery reaches end of life, what happens to it? Nothing. Exactly. Because nobody has figured out how to recycle them. They are even more expensive to recycle.
Finally, if you’re unlucky enough to have your car on fire, good luck putting that EV fire out. They have become the firefighter’s worst nightmare.
When you’re trying to educate people, you should do a good job of showing all the facts and not just the ones that please your narrative. Anyone that’s still considering buying a EV, should do the research about the facts I stated above. Yes EV are the future, but as of now, that future is not here and the technology is still new and needs more work.
"Because nobody has figured out how to recycle them." - multiple companies will offer to recycle them. Thats before you consider many car batteries can be reused without modification as batteries in other uses.
EVs catch fire less than 60x as often as a comparable ICE vehicle. Sure its not great when they do catch fire, but having to deal with 60 ICE fires aint great either.
The "facts" you mentioned are common knowledge. People know EVs cost more, but also cost less to run - thats literally their major selling point.
@@Garfie489 first, go read about how the resources needed to build the batteries are mined and where and what type of labor. Second, as far as recycling goes, have you ever tried to recycle a solar panel or a EV battery? The technology is not there. Anyone that tells you that they are recycling it, are lying to you. Make a simple call to the company that manages your normal waste and ask them about it. Then call your local city and ask them about it and see how much they know and what I formation you get. I have done my research on this as well as from personal experience. As far as the cost goes, with the rise in electric bills, it is already just as expensive as gas depending where you live. Many car companies offer free charging for 2-3 years that may seem like a cost cutting strategy, but eventually you will have to pay for the charges and believe me with anything else, once the demand goes up, so will the price of electricity. Also the battery is another cost issue. It’s a known fact that the most expensive part of a EV is the battery. Once that battery is damaged or reaches end of life, (which nobody really knows when that is since EV mass production is pretty new), the cost of replacing it is outrageous. Often times it costs more than the car itself is worth at the time. As far as fires go, most of the car fires that I’m taking about are during major disasters such as the ones we saw in Hawaii. When a fire ravages through town, all cars regardless of engine type will burn.
I’m not against EV. I think it’s the future of travel, but right now, we don’t have the infrastructure, the ability to properly recycle the batteries, or even any idea how long they last and how expensive they are to repair. That’s not to mention the fact that it takes so long to charge a EV. Imagine if tomorrow half your city had EV, how long would you be waiting in line at a charging station to be able to charge and go? What about travel? Assume you want to go from Los Angeles to Las Vegas which is about a 240 mile trip. What would happen is highway 15 gets backed up or if there’s an accident? How will you be able to charge your car? Will you even make it to your destination? How about cross country drives? This was the same issue we had back when the automobile was first introduced. It wasn’t until the late 40’s and 50’s when they started to have gas stations all over where people weee able to travel long distances which is when the highway systems were built to accommodate that. It took decades not few years. It took decades to build engines that were more reliant, inexpensive, and better gas mileage. Right now we are at the cross roads of where horse and buggy meets the automobile was 100 years ago. We need to invest time and money to improve and eventually make that change.
@@WWTormentor i regularly recycle the same batteries as used in EV's. For me, its as simple as putting it in the correct bin - because there are multiple companies out there that do exactly that.
My "local city" has one such bin at our local recycling center. Its really not that hard - your "research" likely doesnt meet the standard of what research actually is, given it can be disproven by a simple Google - nevermind this being a part of my PhD.
It costs pennies to "refuel" an EV, whereas it costs a days wages to do the same with an ICE vehicle. They are not comparable.
Also major events like forest fires wouldnt affect the average that much, because as you say - both burn. Thus the average is the same for both - yet ICE vehicles have a rate 60x higher than that of EVs per vehicle sold.... which actually suggests the rate of ICE fires is actually worse.
The majority of people drive less than 50 miles a day. If you have an EV with 250 miles of range, you may only need to plug it in once a week whilst at home overnight. The majority of EV owners never have to visit anywhere to recharge - so if half the population had one, itd be no issue at all in terms of finding a charging station.
Nobody seems to be talking about where we're going to get all of this lithium and nickel from needed in these batteries, there are only so many potential mining sites.
Wow. this TED-ED video quickly showed so much bias to electric vehicles.
As an education channel, please stay as neutral as possible, or at least appear as neutral as possible. Of course, that doesn't mean you can't take a side in a debate but at least bring up both facts on sides to make a conclusion instead of blatantly favouring one out of the blue (Like did you mention the environmental cost of rare metals in EVs?)
The video we’ve always wanted 🎉😮
I wish people talked more about ethanol engines.
I thoroughly enjoyed the animation❤
