I don't think you understand what I am saying. It is not about who pollutes the least or most. It is about who is being the hypocrite.

Somone who chastises others for their carbon footprint or lobbies congress to have more carbon credits while flying hundreds of miles on a jet and using kerosene rocket fuel because the lower emissions rocket fuel is too expensive even though he can afford it is a hypocrite. Someone who doesn't chastise others for their carbon foot print and doesn't lobby congress for more carbon credit money while flying hundreds of miles on a jet and shooting kerosene rockets into the air isn't a hypocrite.

You think BMW CEO does not send a lobbyist in with the others to negotiate emissions and fuel economy requirements? The lobbyists don't ride an electric scooter to the meeting either.

Reminds me of GM flying private jets to beg congress for BK money.

They all do it.

The original video still did not include the air that is burned in the example shown.

Air isn't burned, the oxygen in it supports combustion. The same amount of "air" comes out of the engine as went in.

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.

I'm an electrical engineer and design underwater data acquisition systems and acoustic sensors and we use lithium ion battery technology for our under water acquisition nodes and battery technology for the last 30 years to date has always been a challenge for packaging and operations so what I see for the auto industry is the battery technology is still the gating item.

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.

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.

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.

Cheers.

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 :)
