I'm so old I remember thinking 200-amp electrical service to a house was big. Now people increasingly are going with 400A. emp.lbl.gov/publications...

I've been looking for something like this. My great-grandfather was an engineer who help build a lot of oil refineries and I've been curious about it for a long time. Thanks for the reference.

Mangrove Lithium’s New Process Could Change EV Battery Production A new lithium refining method uses electrochemistry to cut waste and energy use, easing a key bottleneck for electric vehicles.

Interesting work in lithium refining. Demo refinery set to make 1,000 tons of lithium hydroxide per year in British Columbia starting in the second half of the year. spectrum.ieee.org/mangrove-lit...

I set my alarm for 3 a.m. to photograph the blood moon (lunar eclipse) but alas, it clouded over. The good news is that my test shots from before I went to bed came out. An weirdly flat moon — no shadow contours except a smidgen at the lower left because the sun was directly behind me as I shot.

I knew Dario Gil from when I was covering quantum computers and he was at IBM Research. Our paths cross again.

The Man Who Stole Infinity | Quanta Magazine In an 1874 paper, Georg Cantor proved that there are different sizes of infinity and changed math forever. A trove of newly unearthed letters shows that it was also an act of plagiarism.

Georg Cantor, pioneer of the mathematical concept of infinity —and plagiarist. How many of us have heard of Richard Dedekind? www.quantamagazine.org/the-man-who-... #math

Dear 1Password: Just bite the bullet and say "Important: We’re increasing the cost of your subscription." Because we all know what "updating the cost" in the subject line will mean.

Also, aren't subscriptions supposed to pay for ongoing development and innovation?

Gripes aside, I like 1Password.

We separate the foundational physics & machine challenges of Q>1 / milestone 4 from the plant challenges of net electricity / milestone 5.

Q>1 is monumental on its own; after that, net electricity is significant enough to warrant another milestone.

You'd prefer we combine those 2 steps into 1?

Note the second bullet point here about conversion inefficiency. Net electricity means you have enough fusion power to handle all these factors. If you can't handle all of that, you haven't reached net electricity / milestone 5. "An electricity meter tracks power usage at the plant boundary."

Are you assuming that our ARC power plant will, like SPARC, have a short pulse followed by a long pause?

SPARC is not a power plant and it doesn't have a blanket. ARC will. The blanket's purpose is to cool the machine, breed tritium, and supply heat for the steam turbine.

Fifth step on the path to fusion energy: Net electricity | The Tokamak Times It’s time to write about the fifth milestone to fusion: generating net electricity. That means producing, collecting, and controlling enough energy that it could be sold onto the power grid.

Pricey blockbuster GLP-1s are costing users — and most of the rest of us, too — Harvard Gazette Health insurers are passing along cost for coverage in form of higher rates across the board, policy researcher says

“If you look at the change in your health insurance premium this year over last year, about 30 percent of that is GLP-1s." –Luca Maini, assistant professor of health care policy at Harvard Medical School.

How much do insurers get back from better health outcomes?

This jumped out at me, too, during the halftime show. It took me a few seconds to realize why there were linemen working on power poles.

As if on cue just ahead of Superb Owl Sunday, a great horned owl hooted nearby just after sundown at the end of yesterday's hike in Wildcat Canyon Regional Park near Richmond, California. Took me a few minutes to find it in the trees. Quite a specimen! #superbowl #birds 🐦

I gotta say, it's pretty gnarly.

Commercial or community perhaps -- a big field of them

On my shuttle ride west of Boston last week, I drove past a lot of solar panels still covered with snow on Friday.

Late Friday night / early Saturday morning in Boston, still with a lot of snow on the ground.
