  • A bit more technical detail from greencarreports. I was wondering if 800v charging necessarily implies anything about motor voltage, and apparently it’s “sometimes”.

    GM’s GMC Hummer EV, for instance, runs at 400 volts, and each layer of its dual-layer battery pack operates in some ways as an individual pack. In 400-volt charging, the packs are connected in parallel, but for 800-volt charging a switch allows them to be connected in series—like the cells in a long, multi-cell flashlight—to take advantage of the higher voltage.

    That 800-volt “trick” permits the Hummer EV pickup, with its 205-kwh battery pack, to charge at 350 kw and gain nearly 100 miles of range in 10 minutes—despite its 400-volt system and its inefficiency compared to other EVs.




  • I am annoyed by Christmas before Thanksgiving, but the change doesn’t seem that egregious, just avoiding the case where it could be a week later than usual:

    in 1863, during the Civil War, Abraham Lincoln established the last Thursday of November as the official date for Thanksgiving to be celebrated each year. Following this tradition, every president thereafter declared a general day of Thanksgiving to be observed on the last Thursday in November. However, in 1939, during the Great Depression, November had five Thursdays, and the last one fell on November 30, which left little time for the Christmas shopping season. To address this concern, in August 1939, President Franklin D. Roosevelt decided to break from tradition and issued an executive order declaring that Thanksgiving would be celebrated on November 23 instead of November 30.

    Also it didn’t work:

    A 1941 Commerce Department survey found no significant expansion of retail sales due to the change.







  • Aljazeera has a scant few additional details:

    Police said the officers were there to serve a warrant. At a news conference, Christopher Paris, the state police commissioner, explained that they were following up on an investigation that began the day before, but he shared few other details. “The general heading of that investigation, I would say,

    From the original article:

    “This kind of violence is not OK. We need to do better as a society,” Shapiro said.

    Seems like quite a juxtaposition there. I wonder what the “disturbance” was, and what de-escalation approaches were attempted.
