Wall Street Journal: For Maximum EV Efficiency, Stick to 25 Miles an Hour, Ignore Angry Drivers

Saw this article posted, figured it's rare to have hypermilers in the news at all. Enjoy!

Sorry for thread-jacking the most recent EV post, but....

An anonymous reader quotes a report from New Atlas:

Quote:

For the first time, a team of scientists has now demonstrated the quantum mechanical principle of superabsorption that underpins quantum batteries in a proof-of-concept device. "Superabsorption is a quantum collective effect where transitions between the states of the molecules interfere constructively," .... Crucially this allows the combined molecules to absorb light more efficiently than if each molecule were acting individually." In a quantum battery, this phenomenon would have a very clear benefit. The more energy-storing molecules you have, the more efficiently they'll be able to absorb that energy -- in other words, the bigger you make the battery, the faster it will charge. At least, that's how it should work in theory. Superabsorption had yet to be demonstrated on a scale large enough to build quantum batteries, but the new study has now managed just that.

Possibly they are conflating 'battery' and 'cell'?

I'm still holding my breath from 3 years ago when this fabulous news was rumored;

I'll have to ask Alberto for the latest, and continue holding my breath.

Might explain the sudden prolifferation of high visibility student driver signs here in Reno. Cant be that many driver schools, can there?

I wonder what the purpose of student driver signs is? Not like I drive any differently, because they still have to obey all traffic laws. My assumption is there are a lot more driving teachers these days. I'd bet the majority of kids get paid instruction. Back when I was learning, that was hardly a thing. Nobody I knew had paid instruction. At 15, I did all the driving when accompanying my parents, which is how I learned.

My thoughts were: keep you from being violently assaulted post faux paus driving incident. Cut some one off and not get shot, perhaps

Just going through this with my daughter. All the driver's education classes were full indefinitely. The only way to get a lerners permit at 15 is with a driver's education class which costs like $350. Thankfully our good governor saw the backlog and changed the requirement that said you have to be at least 16 to learn from you parents, so she was able to start when she was 15 for free at home. She is now turned 16 anyway but at least her 6 months is done, now she just had to wait 2 months for a testing spot to open LOL. Some offices had a 6 month wait for the road test!

When I drive my wife's car, C-Max PHEV, I always turn on emergency flashers if I know I am going to drive 10MPH or slower than posted, so far *knocks on wood*, nobody has honked their horn or gave me the #2 salute :turtle:

Ah, laws must have changed.

I think when I was 15, I just had to take a written test and pay a minimal fee to get the learners permit, which allowed me to drive whenever I was accompanied by an adult licensed driver.

At 16 I just had to pass a written and driving test, pay another fee, and got a full license.

Motorcycle endorsements required a class to be taken if someone was under something like age 25. For a highschooler, the $250 fee for the 2.5 day class was pretty steep, but well worth it.
