"Big rigs will have to slash fuel consumption by 23 percent".

That's what Obama said in 2008, none of it happened.
Sounds like a huge outlay of capital for no increase in GDP.

Who just announced a utility-as-a-service product? I forget.

Nobody took the bait.

* In a democracy, it doesn't come down to what people say to determine what will happen.
* It will be an enormous outlay of capital, but if the experts are correct, it won't be enough to reverse what's been set in motion since 1957.
Some economists will argue that without this outlay, we may not have a GDP.
* I can walk through Denton, Texas today, on concrete sidewalks created by Roosevelts Works Progress Administration during the Great Depression.
* And I routinely drive on 1956 National Interstate and Defense Highway Act freeways.
* Pretty amazing investments!
* Airports
* Ports
* Harbors
* Levees
* Pipelines
* Dams/reservoirs/ municipal water systems
* Safe drinking water
* National electric codes
* National plumbing codes
* National building codes
* Transmission lines
* Pentagon
* FBI
* FDA
* CIA
* NSA
* NRO
* RAND Corporation
* JASON
* National Laboratories
* etc.
All publicly funded. Still working for us daily. Things the private sector couldn't or wouldn't take on.
What a bargain!!!!!!!!!!!!!!!!!!!

Sounds good except for the TLAs. It doesn't always seem like they're working for us.

In a democracy deep state, it doesn't come down to what people the President say to determine what will happen.

That list is far from a bargain IMO. It's all money we don't have and the gross expansion they are planning is even worse. The only possible way to pay for all of that then and all the planned stuff going forward is to devalue the current dollar with inflation or flat out just print more money. So just as everything costs 10 times what it did 100 years ago will probably be 10 times more expensive in just 50 years now. All the while people continue to give away freedom. Take the building codes referenced. My house was built long before they were installed. My house was built by a shepherd with 4 kids and their own hands, only hand tools, and horses. They could never do that today with all the codes and inspections. They have to hire people they can't afford to build a house that may not suit them as well. As far as, is it built right? Well when those fancy new home with their codes have been here 100 years they can ask my old house that question.

Seems like they've pretty much 'nailed it.'

At what distance was that inductive coupling accomplished?

Almost everything that radiates drops off with the square of the distance, so unless your inductors are practically touching your efficiency starts getting poor rather quickly.

If you have to have the two parts basically touching, why not just have a plug at that point? It's cheaper, it's well-understood, and it's here right now.

I was discussing coil to coil charging with my brother-in-law and he said high efficiency over a significant gap is technically possible, but requires higher frequencies and the coils and capacitors must be tuned to a set standard, IIRC.

Another reason to use coils, even if they have to be right next to each other, is that it reduces the risk of shock. Now I've never heard of someone being shocked by an EVSE or DC quick charger, but having high power, high voltage bare metal prongs outside where rain and other sources of conducting liquid could make a path through your body is still a risk.

It seems worth doing just so you don't need a robotic tentacle. ....for that....

Fuller pointed out that the sum total of the world's technology was operating at around 4% efficiency. 8 More up-to-date analysis has put the efficiency of the US economy at around 6%. 9 By raising the efficiency of how we manufacture, use, and dispose of our products, we could raise the overall efficiency of our technological lifesupport ...

In 1961, R. Buckminster Fuller proposed an alternative to war games, called the World Game (or World Peace Game), which was part of Fuller's Design Science Revolution.

The government mandated DPF garbage be installed on trucks and that lowers fuel milage.

The current Freightliner Cascadia is 33% more fuel efficient than the original 2006 model despite reducing allowed SOx, NOx, and PM emissions by 95%

But that may be just picking a terrible 2006 model that was finally fixed.

How much better is the best available class 8 2021 compared to the best available 2006? Or the average 2006 to 2021? Or the fleet average 2006 to fleet average 2021? That was a long report giving numbers that really have no bearing on the problem and probably took longer to dig out, than just telling us the non conformational bias numbers.
