We should have already been there, radical enviros fricked it up.
They are by far the loudest but not the biggest impediment to more nuclear production. Small radical groups are easy to overcome with the momentum of a majority of people but that majority still harbors a large number of stanch NIMBY people. It doesn't matter is 99% of people in the US want more nuclear if the vast majority of them also don't want it in their backyard then you aren't going to get it.
Over the 50+ years of my life people have moved fack and forth across the pro/con gap of the nuclear power question. In the last couple of years with events like Fukushima disaster fading like events (and movies) of the past did we seem to be at or very close to another positive inflection point. That however is a general statement on nuclear, people are still entrenched about their proximity.

>>How will we fill this shortfall??
A friend has a company that makes batteries. For satellites, among other things. He's been saying this for years.
This also does not consider that the fast charging stations tax the system much more.

Not a very good one
quote:Yeah about 5kw for a while, and then less than 2kw to maintain. You said 2kw was "laughably short". It is clearly well inside the ballpark on average. Might even be high.
Even so you can see where it was drawing far more than 2kW during some of that.
quote:I'm well aware how big a role humidity plays, no formal thermodynamics education required. However I would love if you would show your work regarding humidity encroachment in a typical home vs a Tesla cabin, and the math related to AC efficiency. So far all you've done is spout nonsense about how smart you think you are, and how you know better than the people who have actually tested the issue, and provided absolutely zero evidence to refute the results that others have found.
Now in a state where it will be 90F+ and high humidity those numbers will jump considerably, this what people with little formal education on thermodynamics and heat transfer systems fail to grasp. Humidity is an enormous factor on the efficiency and power requirements for an AC system, roughly 34% of the power consumed by an AC system in Louisiana goes into simply condensing water vapor into a liquid that is dumped onto the ground. And that's in an indoor system trying to maintain a roughly comfortable 63 - 65% RH, much worse for automotive systems.
quote:Uh yeah I seriously need an explanation of why it seems impossible and unsafe to you to power a house for 2 to 3 days when the equipment is clearly capable of pushing that amount of power into the vehicle 5 times faster than that.
Do you seriously need an explanation of how limited the power capacity will be attempting to safely backfeed an average house from an EV with even the largest residential charging stations?
quote:It's actually closer to 10% total loss round trip after both conversions, AC to DC and back again. But I'll give you 20% and tell you it's still 10X cheaper to run your house for a day from your EV than to burn natgas.
The fact that 20% of the capacity is wasted right off the bat converting it from DC to AC?
quote:
Using an EV in place of anything more than relatively modest generator isn't happening, certainly not going to run major appliaces or HVAC outside of a gas furnace.
FYI people already use home battery packs that are only 1/5th the size of the ones in vehicle as backup power.
Also, you have been going on about how power hungry car AC is, roughly the same as a home's central AC correct? Clearly the car is able to run its own AC and drive itself down the highway. It can run 10 air conditioners, but now you think it "certainly" can't even run 1 home's air conditioner? You're a joke.

quote:A typical Tesla discharges at 20kw just maintaining highway speed, and at more than 10X that rate surging under acceleration. How are you defining "capable"?
A 12kW generator is still far more capable than any EV right now
quote:You can make up a number like 50% conversion loss, and it will still be far cheaper to run your home for a day on EV power than to burn natural gas. How are you defining "economical"?
and far more economical in providing reliable power

. The most important thing on the local level is socially engineering people to spread out their charging through the night and not all plugin (or turn on) charging when the hordes arrive home at ~5:30 PM local
You will probably see local regulations on residential fast chargers limited to non-peak hours. That solves the majority of the demand issue.
It's amazing that utilities have managed to get the public to believe that kWh are a quantifiable resource.

Could there be a charger that communicates with the provider and gets a discount when charging at the best times.

test versions already exist.
ETA my response to this in a different thread.
quote:quote:
The local grid is where the problem gets slightly less manageable but simple social engineering that power companies already engage in can shift charging of many cars from the 5:30 to 7:30 PM arrival at home for many people to later in the night.
Companies are already testing smart chargers that should help control this. The prevailing theory is to use the tech to make it to where the physical action from the person, plugging the car in, is easy and can be done when they get home from work. Then the actual flow of electrons is handled by a smart device that will either do it at a set time or later when demand is low and cost will be less. That's the key is incentivizing the user so I think you'll see more variable rate programs to push this.

And how's that any different than the person who left in the ICE vehicle with the same "range" left with the tank low? He's going to have the same issue, and having to turn his AC off as well.
The ICE driver saw the delay on the WAZE app, took the first available exit and topped of their tank at one of the many gas stations

No one expects the US to go fully electric. You just have to introduce power at the same rate as EVs hit the road. Lots of options- nuclear, solar, wind, hyrdo, gas, etc.

Tesla driver saw the traffic delay right on the screen on his car, exited and goes to a super charger to charge up. Tada... But again, that's not what we're discussing, you're trying to change it instead of just conceding you didn't realize a Tesla being stuck in traffic isn't any more likely to run out of jui E than an ICE vehicle is likely to run out of gas.

Unless there has been a dramatic shift in the last 18 months mining still produces more than brine, although the trend towards brine is accurate.
This doesn't even begin to touch the outlook of EV's if aluminum batteries take off and take the place of lithium.

Past videos of Camp Mode have shown that a nine-hour night of sleep only consumes around 10% of the battery’s state of charge, which is not very much considering the climate control and airflow that is operational throughout the evening.

Unlikely, for 2021 there are only 986 Tesla supercharger stations in the US, the ICE driver has 115,000 gas stations to choose from. Those two numbers will never converge leaving the Tesla driver following a rabbit trail between charger stations.

I remember rolling blackouts.
Sane people aren’t scared of EVs. Same people are scared of the complete lack of infrastructure.
And to ask where we get the energy and why the major push for EVs, look no further than Bill Gates and Warren Buffett.

TerraPower, founded by Gates about 15 years ago, and power company PacifiCorp, owned by Warren Buffett’s Berkshire Hathaway, said on Wednesday that the exact site of the Natrium reactor demonstration plant was expected to be announced by the end of the year.
