Try the finished version! Those were just the unedited notes from 1988, and over later years I used them for a large number of articles and essays. http://amasci.com/miscon/elect.html is the big list of electricity m

These aren't articles. READ THE FIRST LINE. They're random crude notes, scribbled down in 1988, and UNEDITED, so full of all sorts of horrible mistakes (that's what "unedited notes" means.) The actual completed a

It's not an article. It's not supposed to explain anything. Read the first line. It's a wad of notes, a bunch of totally-unedited crap scribbled on napkins in 1988, while THINKING about writing a proper article. For th

Tesla is vindicated: it turns out that this whole article was debunked in 1936, but the debunking was based on an error. Single-wire transmissions are not against EM theory after all! Zenneck surface waves had long been disproved, but sin

Also we don't really know what Optics is. Is it the lenses and prisms? Is it the light waves? Or is optics really the photons? Yet try as we might, we can only see the EFFECTS of optics, but we're not one step closer to und

If "electricity" is really just a category ...then we've just added another definition to the list! That just makes things worse! (Well, unless you can somehow erase all the competing ones. Better choose one definition and

I suspect that it corresponds to Newtonian Statics, the study of mass and forces. It's a subject area; an ignoring of changes. Not a state of nonmoving. The Newtonian Statics viewpoint involves summation of forces. It may also invo

DOH! Fixed now. I messed it up last time I was getting slashdotted by reddit and ycombinator, and everyone was complaining that the raw unedited notes were just a bunch of raw unedited notes. Heh, it's still a 1995 gopher-era design, b

Yep, a VDG machine is not a single-ended device. I tell people that there are always two spheres involved, although usually the second sphere is below our feet: planet Earth. Charge conservation says that, with a VDG, the e-field flux ex

Note that photons only travel along FO cable because of the charge polarization of the silica. This is a direct analog to 60Hz "electric power" traveling along a column of mobile charges in a long conductor. In both cases, the

Actually, it's electric wattage which is the moving photons, not electric current. Energy flow. Joules per second, same as with laser outputs. So, the electric companies are selling us 60Hz photons. But at the same time, the AC ele

It actually is the electrons. But they never touch each other. Instead they push upon each other across empty space, by using e-fields and b-fields. If there wasn't any chain of electrons inside the conductor, then the EM fields wo
