Waiting for Superbatteries
They are still a long way from matching the energy density of liquid fuel

There is a lot of research being done looking for a better EV battery that will give top performance with the use of benign chemicals, and will max charge in minutes without damage, and is recyclable and cheap.
Until that happens EV are going to have tough going. Most houses have a 200 amp service panel. Well, if you outlaw gas you need another 30-40 amps for your washer & electric dryer, Central electric heat and air - another 40-60. Range/oven another 40+ amps.
I doubt it is even legal to wire in a “night use only” circuit.
Our electric is made with mostly fossil fuels:

There is no way out of fossil fuels without embracing nuclear power.

 

Given the fact that nuclear has panicked people for decades and will take a minimum of 20 or more years for anything new to be approved in the US, technically there's no way out of fossil fuels at all.

 

Besides, everybody seems to skim past the most obvious problem with the idea of batteries (and hence EVs)- batteries are energy storage devices, not energy release devices. One has to first release the energy that will go into a battery and then get it into the battery so it can then be released again to make the EV go.

Every single step in that process depletes the energy that was originally released and uses it up in the resistance of getting it there.

EVs will simply never outperform good, old internal combustion engines which release and use the energy right at the source.

If you look, there's a lot of hype right now about the Tesla semi. Supposed to get a whopping 500 miles on a charge. Everyone should be laughing their arses off.

 

Obviously, the Green Weenies are not realists and people in the Green industry who live on subsidies are feeding these people false information.

The biggest crop in the Green Industry is subsidy farming all day, everyday.

 

Which is why the ONLY scientific research we should be doing is nuclear fusion

And power broadcast, but fusion first

 

Fusion would solve ALL our environmental problems. It's clean, safe, abundant and cheap. The only drawback is it's rather large startup cost. About 100 bill to start.

I'm looking at YOU Elon.

 

And fossil fuels are, of course, infinite, that's why they're called fossils. [/satire]

Or maybe sweet JeHAYsus will make us some new.

 

Equally short sighted.. The real effort has to be affordable reliable energy. It cannot become a step back to the stone age until it becomes available.

 

Yes! Success has been right around the corner for like 100 years?

Uhhh…no. You are looking at his money.

My idea would be small reactors, much like used in aircraft carriers. They would be decentralized and put in or under secure locations: military bases, police stations, government buildings.
But the media will scare everyone away!

 

And what does that have to do with anything?

 

What are we supposed to do once all the fossil fuels are gone? That WILL happen and probably sooner than anyone thinks as we use more and more all the time

 

EXTREMELY dangerous. Why do you think they're only used on military? Why not VLCCs and cruise ships? Fission is inherently dangerous, a controlled atomic detonation and if anything goes wrong it blows up (or melts down). With fusion the problem is keeping it going. If anything goes wrong it shuts down.

 

We have hundreds of years of coal and filters that collect all the coal emissions except the one plants need to breathe. Fusion will be great, but coal will keep the lights on while we figure it out.

 

There are regenerative braking system on most EVs I'm aware of, but I'm not sure how well that works.

The REAL problem that people aren't talking about are charging stations.

Huge areas are blank for EV charging in the US. Many of them are located at hotels that you can't use if you're not a guest. Many of them are really old models that charge slow.

It can take an hour or more to charge, instead of a 5 minute stop for gas. If the number of EV's doubled overnight on the roads it would be a disaster.

Then you have state specific issues. CA can't even keep the electricity on now. How are they going to do it when the grid goes down....either in an emergency situation or just their normal incompetence?

 

Fission could keep the lights on and not ruin the climate, but Fusion is feasible now, given a Manhattan Project.

 

Then you're ****ed. No amount of solar panels and wind turbines is going to work.

You're talking about going from over 9 trillion kwh just for what we use now.

We only produce about 25% of what would be needed NOW.

 

My guess would be that humanity will figure it out when the time comes. And from what I've heard, places like North Dakota have something like 800 years of coal. And that's just coal and just North Dakota.

Besides, what exactly are EVs supposed to be doing to help with that question?

 

You want to laugh about the semi. But, remember that those who worship diesel believed that was totally impossible.

People laughed at the first personal computers, the first cell phones, the first cars, the first electric transmission technology, the first airplanes ...

So, at least you aren't alone. You do have that!

 

At least 2/3 of our oil consumption goes to transportation.

Consider the impact if we could cut that in half.

Plus, consider the healthcare savings of major reductions of pollution in our cities.

 

Don’t underestimate Australia lols!

This is why India and China are leaning heavily toward EV use

The major solution for that comes with charging being available at home, including apartments. Today, apartment dwellers often have to depend on charging stations, but that is becoming a competitive advantage for building managers to consider.

Also, those who park their cars at buildings where they work have that as a potential recharging site. Many corporations are adding that, as are places like shopping centers.

Of course, there has to be more to really answer the need. So, both government and private enterprise (like Tesla) are creating more charging sites and making them available to all.

Battery technology has improving significantly, allowing for faster charging and larger capacity. This is where capitalism shines, as there is gigantic demand for battery technology.

 

Amen.

There's nothing like capitalism.

But, it sure helps when government understands the advantages and adds to that - like they do for pretty much ALL transportation improvements as well as for subsidizing oil pumping and facilities and helping to support the incredible costs of healthcare.

In the US, our economy could be better off by being a lot more free from oil. We'd have better control of our inflation. We'd probably make better choices at the Pentagon. We probably would have greater respect for the land owned by native American nations.

We definitely would have lower healthcare costs.

And, that doesn't even touch on issues of fisheries, climate, etc.

 

India is literally “hopping on board” as they are already heavy users of rickshaws and motorbikes - it does not take a genius to realise that if they get those vehicles replaced by something way less polluting then the air will start to clear

 

And that's still a long way from being an actual useful semi.

It still ain't happening. Not with those laughable specs.
