Gasoline vs Battery Energy Density Explained

[FishOnOne]

I thought Engineering Explained did a good job of explaining energy density of both gasoline and battery capacity. This video also gives a good insight of the technical and the economics challenges Electric vehicles face and why it makes good sense to continue to improve the Internal Combustion engine.

Video 2 explains the efficiency of the two different sources of energy.

You guys are beating a dead horse. EV's are the future like it or not.
The ICE is just too inefficient and complex by comparison.
Yes there are lots of challenges and logistics but I think Tesla has shown it can be done.
No every vehicle cannot be replaced by an EV .................yet!
But in time 90% of vehicles will be EV.
The debate at this point is not about technology but about money.
Mobil Exxon is not going down without a fight.
Global Warming is not about the environment, It's about the money,mindset and desire to transition from fossil fuels to renewable energy sources.
EV's vs.ICE. is just one front of the energy battle.
The energy revolution is upon us.

Problem with ice engine is,
NOT a single auto maker cares about improving its eficiency.


There are plenty of inventions out there but no one cares about using it

Heres one

Why doesnt anyone put those on their engines?

I tell you why,,they want drivers to burn as much gasoline as posible bc thats how they make money!

Lets face it electric motor is 99% eficient and gasoline cant ever compete.
Once EVs become affordable for everyone fosil fuel is dead.

If you look at modern DI turbocharged gas engines in use today, you see that they are close to the same efficiency as Smokey Yunick's adiabatic engine he developed in the 1980s. 1.8 hp per cubic inch (about 100 hp per liter) is common place today, and while Smokey's motor got 50 mpg highway in a 2500 lb Fiero, a current DI gas motor of the same output would get close to that in a small, light car such as that. Part of what saps efficiency compared to what it could be is that cars are simply much bigger and more powerful than the 80s. Compare a 1985 Honda Accord to a new one. The 2020 car is much bigger, much more powerful, and gets significantly better EPA rated mpg.

You think the CEO of BMW rides an electric scooter?

Shiner you and I see this in completely different ways. I respect but will never agree with your opinion on Tesla, Space X or Elon Musk.

So someone who does all that gets a pass simply because he is the CEO of your favorite car brand? Do you have to agree with everything he does or are you allowed to disagree with some of the things he does?

Yah. Pointless going down that road dude. We see things much different. And for the record my favourite car company is Jaguar followed closely by BMW. They unfortunately don’t presently make anything that suits our needs. My wife chose a Tesla, my commuter is a Nissan Leaf.

I guess so. Because I am not afraid to call out hypocrites like Elon and Tesla who like to chastise others for their carbon footprint yet pollute way more than the average person all while profiting from it.

The same goes for all these SJW's calling out issues in the US as the worst country in the world yet buy Apple products made from Chinese sweatshops with obscene suicide rates from being worked to death.

Amazing that not one enterprising company is interested in such proven technologies. Why would they? Who wants to buy a car that uses 50% less fuel than the competition? It would be crazy to produce such a vehicle, would never sell!

BTW, where is the link to the 100 MPG carburetor?

Some are working on it. The Mercedes F1 hybrid power plant has exceeded 50% thermal efficiency. It puts out the same amount of power as the 2005 V10 engines on just over half as much fuel.

Emissions or not the video fails to mention much of the fuel reaction is taken from the air.

If electricity was provided en-route within the roadway then energy density would favor the electric motor.

Now go burn some diesel 🙂

Bad old Elon. Such a bad dude. :). Keep it simple. Get your government to deport him and shut down his companies. Or at least force him to move his companies to another country. 🙂

So you support someone being a hypocrite telling others that they should reduce their carbon footprint while they fly hundreds of thousands of miles on a private jet because they don't want to fly with other people and blast hundreds of kerosene rockets into the air because they don't want to spend the money on the fuel that emits significantly less pollution like what NASA uses. Not only that, but lobby for higher carbon taxes on companies so they can make more money on the backs of consumers on top of lobbying for more tax credits. I would be against anyone being a hypocrite like this, not just people named Elon.

If Elon was not being a hypocrite on these topics doing the very thing he is telling other people they shouldn't do, then I would have nothing against the man or his company. If he never chastised others on their carbon footprint, stated that the main purpose of building his cars was for better performance(like Porsche does with the Taycan), and did not try to increase carbon tac on companies just so he could get more money, then I would have nothing against him living the lifestyle he does. My problem is with the act, not the person and I don't give him a pass regardless of whether I am a fan of them or their products or not.

Tesla gets brought up when Tesla fanboys like to bring up emissions because their CEO does not seem to live the "holier than thou" low carbon footprint life style with all those private jet flights and shooting kerosene rockets in the air. If one tout's improving the environment as reason to buying one like Tesla does, then it probably not a good thing to have a leader who emits more CO2 than 90% of the populous. It seems he is a do as I say not as I do like the rest of his zealous fanatics.

However, if Tesla's main and only approach to buying one is better performance like the Hummer then they would probably get a pass from more people for not being so hypocritical.

I don’t know. I’m pretty sure Mary Barr flys around in a jet too. :). But, you know, that’s different. It’s not Tesla. :).

Does Mary Barr chastise others for their carbon use? Does she lobby for an increase for carbon tax on companies so that her company can make more money selling carbon credits even though the private jet flights and kerosene rockets are except from the made up rules? The difference is that Elon and his fanatics tout emissions yet hypocritically overlook the emissions that Elon is pumping into the air because he does not want to practice what he preaches.

I am sure things would be different for him and his company if he either practiced what he was preaching or if he never preached it all.

I love how any battery or EV discussion turns into an instant Tesla hate fest. Too funny. :). Any other manufacturer (especially foreign manufacturers) are OK though. Just Tesla. :).
