Why EV's suck on energy efficiency

[T. A. Gardner]

While Capitalist Joe (an oxymoron given his posts) is afraid to openly debate this by banning those from his threads that would, I'm not. Here's a visual comparison on why EV's suck on efficiency.



This video explains in a simple and visual way why EV's are often a poor choice as a vehicle. It also explains why they are not particularly more efficient at, well, virtually anything, over ICE vehicles.

So, if you believe AlGore, high priest of Gorebal Warming that if you don't buy an EV you're going to die in a human created furnace, by all means buy an EV. Just don't force the fucked up things on the rest of us.

It's also insane to celebrate totalitarian, authoritarian, and fascist government edicts forcing people to buy EV's. Anyone with a reasonable desire for freedom of choice would oppose such government dicktats.

They are great for virtue signaling.

A lie a day keep the ICEs away.

If you live in a temperate area and mainly toodle around town or commute to work and need a nice looking late model ride, they can be an effective choice.

If you live in hot or cold areas it becomes less so and will require that you have a garage.

If you travel it starts to become a worse idea. The more you travel, the worse it gets.

If you need hauling ability again it becomes less effective.

Hydrogen powered ICE and FCEV cars will blow BEVs away.

He is also a plagiarist!

Anhydrous ammonia fuel is another alternative that works. It was first used widely in Belgium during WW 2 during the German occupation because gasoline was unavailable. The Brussels public transit system ran all their busses on it converting extant ICE engines to use it. In a fuel cell it is more efficient.

So, the myopic view that batteries are it and the future are exactly that, a myopic and dead end view of the future of personal transportation.

Our overlords clearly dont care. Going forwards most people wont even be able to have cars under their plans. You might be able to call a car if your social credit score is good enough but mostly you will walk or ride a bike or something like that. Some people say that OneWheels are nice.

40-50 hours
Level 1 chargers can take 40-50 hours to charge a battery electric vehicle (BEV) from empty and 5-6 hours to charge a plug-in hybrid electric vehicle (PHEV) from empty.Feb 2, 2022

You come home from work on Monday and have to wait til Wed. for your car battery to be charged.

Uh huh

The chief of the world’s largest oil company is worried about global crude supplies.
Current market dynamics — such as China’s slowdown and an aviation sector that is still recovering from the Covid-19 pandemic — have kept demand relatively subdued, but that is set to change soon. Saudi Aramco CEO Amin Nasser fears the world won’t have enough spare capacity to deal with that shift.





“For crude oil, we are in a situation where there is a spare capacity that is helping to mitigate interruptions,” Nasser told CNBC’s Hadley Gamble. “However, I am not so sure about the mid-to-long term, because as the spare capacity erodes, we will not be having the capability to mitigate any short or long term interruptions like what happened with Russia-Ukraine crisis.

Why EV's suck on energy efficiency

Maybe later in the video he switched to something about energy efficiency, but for the first 3 minutes all he talked about was energy volume efficiency. That is kind of important, but is very different than energy efficiency.

An ICE engine needs to be running all the time, even when it is not needed, which is a massive energy inefficiency. It also has built into it lots of friction, which is another inefficiency. It is not that hard to get an electric motor to be 90% efficient, where it is virtually impossible to get a combustion engine to 50% efficiency without combining it with an electric motor.

So a modern diesel locomotive gets slightly above 50% efficiency, because the diesel engine runs at one speed, charging batteries that run an electric motor that actually moves the train. Electric only trains are even more efficient because you eliminate the friction of the diesel engine.

He is right that, currently, gasoline has better volume efficiency than batteries.

More bullshit Salty, Volkswagens have a start/stop system that stop if waiting at traffic lights or in a huge jam.

Yes that's true as with many other applications throughout history.

You lie a lot, and it does nothing to keep the ICEs away, so obviously you are lying AGAIN.

If you live in a temperate area and mainly toodle around town or commute to work and need a nice looking late model ride, they can be an effective choice.

IF you also have a home (and probably garage) to charge it.

If you live in hot or cold areas it becomes less so and will require that you have a garage.

The garage is already basically required to be practical on any level, so this is superfluous.

If you travel it starts to become a worse idea. The more you travel, the worse it gets.

Quite right. The more you travel, the more you will have to stay in many hotels because your car needs charging, which takes a significant amount of time out of your travel time.

If you need hauling ability again it becomes less effective.

Quite right. Batteries are heavy, even Li-ion batteries. That's useful load you don't get.

Ever wonder why there are no practical electric airplanes? The same thing affects cars and trucks.

It's all about power to weight ratio and useful load capacity.
