using superconducting magnets the cold will actually be beneficial?
e. caputures by solar panel & stores electricity with ultra dense capacitors, insolation at a rate that makes it economical
there's these things called electrons that are moved when you move a magnet relative to a conductor material, such as copper, these electrons have more power than steam. Switches are signal devices, like valves in a steam engine. We used to use them, for instance, to make a signal pass or not pass. These switches have, over the years, been manufactured to an astounding billions per square inch, they are all called transistors and have no moving parts. Four equations will be sufficient to describe the situation.
kinda strange it took 400 years to get the type on metal rods to strike paper, when all the ingredients were around since movable type. Was it the Angstrom Problem? i.e. couldn't work small type-set until almost 1900 but could make a chronograph for longitude which is much more complex mechanically than a typewriter. Perhaps if Hamilton wasn't killed in the duel, he and Ben Franklin could have invented the typewriter.

be aware that if delete (and overwrite) your comments, that someone can accuse you of saying anything. I had a script that did it automatically. Someone didn't like what I said, by the time it came to them to look at it , the comment was deleted --- just what someone would do with a "uncivil" comment. So, be aware of that. The script I was using edited with random overwrite and then deleted, from the newest comment backward in time until a certain date. I'm not a jscript ninja, but it was open source and within a day I think a reasonable person with any coding experience would be able to moderate the script to their liking. I wasn't aware of how nasty these people are. Very very sensitive.
in US everyone is a journalist by claim and the authorities must respect that.
