The End of Diesel Cars is Near?

I have been trying to eat my way through them for over half a century and still no end in sight.

Thank you for your service.

But.... you'll no longer have your mom.

I could not resist.
Back on topic, that ban is sillly. But, have you ever been to Mexico City? It's bad pollution wise. So I can see that may work for that city.

Globally no fucking way.

Yet how many guys in LA have removed all their cats?

Can't stand them.....

Good.

Diesel was a scam when they tried to label it "clean" anyways.

Its even worse here in the US where half the f'ing morons with these diesel trucks remove all the emissions equipment and coal filters in order to get a few more HP.

Have you been to a US city? It's not any different even in liberal paradise San Francisco, let alone LA.

Hell, go to your nearby freeway overpass and put your hand on any hard surface like chain link or a street sign, it'll be filthy greasy black like a tailpipe. It was like that even in the little town of ~60k people I lived in for a few years.

Does anyone besides @humfrz remember the late nineteenth century in the golden age of coal?

This is the wrong thread. @guybo, you equated the emissions from one powerplant charging lots of electric vehicles to those from the same number of conventional ones.

Yes, we're still burning fossil fuels but it's easier to manage the emissions of one giant powerplant than those from millions of little ones.

I get the battery thing, though. No easy answers when they all involve disturbing "the natural order."

Batteries will hopefully take a step forward in energy density in the next decade or two. Still ships and trains that long haul will need power. How do you charge while moving across an ocean? Solar tech is not there yet.


Anyway, it will be interesting. There is an Electric semi truck, but it costs $375,000 each. So building a fleet of those will be costly. I hope to see electric cars with a 700-1000 mile range. I would adopt at that point. 200-300 miles is too little of a range for me. I regularly drive that much in my car.

I've taken tests on the concept, pretty well thought out at this point. Wish the 'answer' was more common, stupid sound bytes controlling the political landscape.

People have been saying that for over 100 years...

But I guess ~300 miles in a modern Li-ion car @ 60+ mph is better than the ~100 miles at <20mph speeds 100 years ago.



I wonder how those 'super capacitors' are coming...

The business I work for makes Battery powered products. Lead acid, is still some of the most cost effective and reliable for certain applications, like off the grid homes.

All our products use primary lithium batteries. Li-ion has far less density in smaller batteries. Like cr2016 coin cells. Anyway, toyota has put over a billion dollars into research, and I am confident that the step up will happen in our lifetime.

Graphine nano tubes could possibly increase the surface area for the anode and cathode to create higher energy density. We will see.

Vanadium flow batteries are really interesting, though huge. So many different types....

I hope to have the technology trickle down to smaller batteries. would be cool to have a cell phone that lasted a month.


Edit: Man I sound like a insufferable know it all. Sorry, it's just that battery tech is a topic that is directly related to my job and I get really excited. I'll work on toning it down.

[jvincent]

And if you add the energy density of gasoline to that chart you realize why batteries are not the best long haul solution.

I was reading a National Geographic a year ago and I'd say you should avoid eating cats and cows that might have had too much diclophenac.
