Not really about electrical power. Hell, not even electrical per se.
More to do with computing. And computing's driving the future, right?

Nvidia also claims they have a path to continuing Moore's law.
Not necessarily.
They also perform well when the majority of your journeys tend to be local. We have a range of 45 miles in the summerand 30
That's been enough to do just over 70% by distance and 85% by time on battery power. The balance is when we venture further afield.
We get an average fuel consumption of 145 to the (UK) gallon.
The latest version of our car can do 60 miles on a charge so that should improve the percentage travelled on battery.
Hi Max / All:
You appear to misunderstand some of my points in post #793 and failed to notice some others.
Urban journeys are quite often suited to hybrids because they usually have a drive cycle with lots of speed variation due to stop signs, traffic lights, corners, and overall short distances - and THAT is precisely why they suit hybrid vehicles. I assume (perhaps incorrectly) that you live in the UK or some other place where short distances prevail and so your driving habits are mainly short distances on congested roads. If that is true, then the fact that your journeys are mainly short distances in urban settings - is why you get 145 mpIMPg (the UK isn't the only place where Imperial gallons are in use - although we normally use litres these days).
Vehicles that travel long distances at constant speed such as people going from city to city in North America and commercial vehicles such as Class 8 trucks, highway coach busses and even freight trains, airliners and ocean-going ships are not well suited to hybrid propulsion because:
- they exhaust the battery capacity (whether it is after 6 miles or 60 miles) and after that, they are hauling around a lot of extra complexity and weight (from the e-propulsion system) which burns more of whatever fuel they use for the prime mover (Otto or diesel cycle engine...propane, CNG, whatever).
- they don't have sufficient opportunities for regenerative braking which helps charge the battery to assist with taking off from a stop.
The fact that our weather is much colder than your's would make things even worse for your hybrid as most of these cars will run the IC engine if the driver calls for cabin heat or the window defroster for more than a few minutes. BTW - these and AC and the infotainment system as often called hotel loads in the auto industry. This is necessary as hybrids have no other means of providing heat. their comparatively small batteries could not both drive the car and operate the hotel loads.
EVs do have electric systems to operate these amenities, but, despite their much larger batteries (which is why EVs are so expensive) their driving range is markedly degraded in winter, to the point where the current generation of pure EVs are rather impractical for most North American drivers who do not live in cities (again, it is all about the usage pattern of the driver).
One of my buddies is the chief engineer of the City of Sudbury, ON which is in the northern part of our province. He tells me that his local towing company reports that as much as 60-70% of their winter business is towing EVs that have run out of battery charge as a result of inaccurate range predictions caused by cold weather. EV technology is generally not good at predicting driving range outside of certain temperatures and cold weather is one of the toughest use-cases.
The towing companies love Teslas - unless they are on fire.
Anyhow, it's lots of fun to debate this stuff, but when discussing the auto industry, everyone should understand that the car companies (at least most of them) ain't stupid and they don't do things for anything other than business reasons and to comply with government regulations.
Cheers,
Pete

Heard a good interview this week with the head of some UK motor industry confederation that govt targets are distorting the market to the severe disadvantage of that industry. They are already required to sell 22% all electric by value and a steeply rising percentage until no 'polluting' vehicles are sold by, think it's 2030.
But she was explaining the huge difficulties the targets are causing even right now - the market just does not buy EVs in the required numbers, so they have to hold off on sales of non-EVs. Soon, they will have to pay £15,000 surcharge for every not fully electric car sold above and beyond the target percentage.

Pete, I responded to your post #793 in mine of #798 the quote relates to what you had written in #805.
Tesla sales are down 35% from 7 months ago.

That $7.5B is money approved through congress. The key word in that is "approved." That's NOT money spent, it's money that WILL BE SPENT when all's said and done. Fact check FALSE by ABC News.
https://abcnews.go.com/Politics/wir...nt-biden-administration-spending-ev-116290401
"As President Joe Biden's term comes to an end, social media users are falsely claiming that his administration spent billions of dollars on the construction of just a handful of electric vehicle charging stations. Multiple high-profile figures, including sitting members of Congress, have promoted the claims.
The claims misrepresent funding set aside by the 2021 Infrastructure and Jobs Act, also known as the Bipartisan Infrastructure Law, for a national network of publicly available electric vehicle chargers. Biden has set a goal of creating 500,000 such chargers by 2030.
Here's a closer look at the facts.
CLAIM: The Biden administration spent $7.5 billion to build eight electric vehicle charging stations.
THE FACTS: That's incorrect. The $7.5 billion figure refers to the total amount allocated through the 2021 law to build a network of charging stations across the U.S., not the amount that has already been spent. There are currently 214 operational chargers in 12 states that have been funded through the law, with 24,800 projects underway across the country, according to the Federal Highway Administration.
A charger, often called a charging port, provides electric power to one vehicle at a time through a connector, which is plugged into the vehicle. Stations are physical locations that can have multiple chargers.
Secretary of Transportation Pete Buttigieg called the claims spreading online “false” in a series of X posts.
“$7.5B has not been spent, nor anything like that,” he wrote, adding that federally funded chargers are built by individual states, not the federal government, and that most will be built in the second half of the 2020s."
PS... don't shoot the messenger. All I did was fact check the (pretty unbelievable) claim of only 7 chargers built for $7.5B.
The (more believable) fact is that, on average, 1000 new charging stations are coming on line every week.

OK I was looking at an electric car (still am), started checking Wisconsin,
Sigh.
Federal Money allocated in 2021, Then states had to make a plan, find locations etc. get that plan approved by the feds. Then start signing contracts for the private companies to design, acquire, build, chargers and the support infrastructure. As of May 2024 Wisconsin has a PLAN. As far as I can tell as of Nov 24, under this funding/WEVI plan exactly zero have been built here.
The good news is that only three years later the feds did approve the state PLAN. AND we will be the first state in the nation to have federally funded chargers at Casinos.
No mention of chargers at state Interstate highway rest areas.
Good thing having chargers is a high priority or it might take a while to happen.
Meanwhile; there are a fairly large number of privately funded and built chargers.
There's more privately built/funded chargers but I looked through several apps and all the locating apps seemed somewhat clunky to use.
Allison's friend has a Tesla that regularly travels from Baraboo to Minneapolis and that seems to work for them.
Looks to me like unless you are a home owner with off street parking, and with significant funds available, odds aren't very good an EV is going to work for many folks anytime soon.
PS I didn't read that a sum total of 7 chargers cost 8.5 Billion, only that three years after the 8.5 billion was announced only a TINY number are actually available for use.
in 2023 Tesla delivered 600,000 EV cars in the USA.
You may have noticed I'm NOT anti EV. But unicorn farts aren't going to get this change going.

Came from the ABC News link I posted. didn't say how many are from the fed funding.
Agree, but neither is misleading headlines like this one....
Prolly one of the worst things out there to kill support for EV's in general and chargers in particular is misleading claims that do nothing but sour the general public on EV's. Public dissatisfaction ended our involvement in the Vietnam war. Public support put Armstrong on the Moon in '69. Public support or dissatisfaction (still) plays a large role in massive programs, as it should. What are we to make of a public that's (intentionally) ill informed?
That was true about a year ago. I'd suspect there's a few more at this point. Here's a link to the NEVI website. Lot's of info on spending and links to state websites detailing their progress on charging corridors.
https://driveelectric.gov/state-plans/
The cold climate plays havoc with EV's range. Questions that come to mind with the 60%.
How many people leave with insufficient charge to get to the next station
How many don't take the loss of distance due to cold conditions into consideration.
How many dion't do their research on the next station in their trip.
Human error could b a major factor in the 60%, then that figure is used to discredit EV's in turn public backlash, and used for political purposes.
Should EV sales be pushed in such cold climates.???.... Be ok if it was for a week or two each year but that far north or south

Biden-Harris Administration Celebrates Opening of Nation’s First NEVI-Funded EV Charging Stations in Ohio and New York
Friday, December 15, 2023
Official government Article doesn't say HOW MANY.
Skull much to most of the USA experiences significant periods of "winter" lets say below the freezing point of water You saying EV's aren't appropriate for these areas. To most auto owners significant is any time period that involves completing their daily work commute.
Since there is so much mis-information I'd think the FHA would want to tout the facts about installed operating stations they've funded? I've tried three times to find anything "recent" on the FHA site about up and operating charging stations.
Should have read all the links, I doubled up info.

Looks like Honda is planning to release a new electric motorcycle ( the one on the left ) it also has a prototype electric scooter for more limited range city riding.
And are you ready for an offshoot brand of electric motorcycle from Royal Enfield? Sort of like the way Harley separated their electric line of bikes with their Livewire brand.
