Right. The only common batteries nowadays that are truly “batteries” are the 9Vs. The original electrical meaning of “battery” is closer to what we now call “battery packs”.
Franklin was the person who first realized the symbiotic relationship between plants and animals. His scientist friend Joseph Priestly told Franklin about how a plant would mysteriously renew used up air in sealed containers. And Franklin wrote him back about how everyone on the planet owes a debt to all plants, from the greatest tree to the tiniest vine for making our air breathable.
Most EV batteries have multiple cells. Sometimes tens of thousands of them.
See also our term “mailbag,” a bag for carrying the “mail,” or (from the OED)
A bag or packet of letters or dispatches for conveyance by post (more fully mail of letters). In later use chiefly: the postal matter (or a quantity of letters, packages, etc.) conveyed in this manner
Nanotubes (NTs) were all the rage about a decade ago. The first NTs were made of carbon. Other researchers developed NTs made of other materials. One group in China made NTs out of copper. Since the chemical symbol for copper is Cu, this made for a rather unfortunate abbreviation.
I’m not aware of any that are built around a single cell. The voltage produced by a single electrochemical cell is generally between 1 and 4 volts, depending on the chemistry being used; if you wanted to use a single cell to provide the 100-400 kilowatts of power used in an electric vehicle, you’d need to move many tens of thousands of amps of current, and the cables would be impossibly stout. Instead, the cells are arrayed in series to produce several hundred volts, reducing the current requirement to something manageable. Within the propulsion battery pack, many cell stacks are also arrayed in parallel with each other, because making one single series battery stack that’s capable of providing hundreds of amps would require very large cells that would be difficult to cool during use and during charging.
It was Alessandro Volta who invented the Volt [citation needed] and he called the thing that made it a voltaic pile, which you have decided to translate as a stack: a lot of elements (layers) of copper, zinc and an electrolyte in between, conected in parallel. When you connect those parallel elements in series you get a battery.
Small batteries are still called pila in Italian and Spanish and pile in Frech.
More or less, anyway. Plus what Luigi Galvani did with frog’s legs, which is also interesting.
I zinc I might have heard of that guy.
That pun is revolting.
Watt?
It made me twitch
Ohm my god, after reading these puns my head hertz.
Ohm, you need more resistance.
Danny Kaye’s body double for the movie Knock On Wood was future Doctor Who Jon Pertwee.
Apparently some of ze Germans don’t like people named Kevin? I don’t like Kevin Hart either, but that’s because I don’t think he’s funny.
He was born in Duluth, but grew up and went to school in Hibbing, MN (part of the Iron Range). People here always think it’s so cool that he’s from the area, but he rarely, if ever mentions Duluth or Hibbing. Duluth even named a street after him. I don’t think he cared.
Rumor has it, that he performed in a high school talent show in Hibbing and he was booed off the stage!
Dang, I knew this, I read several Dylan biographies, but I always confuse Duluth and Hibbing.
The story I remember heaving heard or read was that the principal cut the cord because he thought it was infernal noise, just like Pete Seeger allegedly tried at the 1965 Newport Festival when Dylan went electric.
Though that story probably is apocryphal, it’s a fact that Dylan initially was a rocker turned folkie turned rocker again, he didn’t start in folk. In his high school year book, he stated under “goal in life”: “to join Little Richard’s band”.
He listened to an Odetta record and immediately bought an acoustic guitar.
Perhaps the American version of “Kevinismus” would be the trend for African-Americans to give their children French, Islamic or African (sounding) names, often with a variant spelling?
He probably stole that album, as he was infamous for “borrowing” records from friends and acquaintances and never giving them back. Assholish behavior, for sure, but what would his career have been without all those musical influences he soaked up like a sponge?
