Moontanman Posted March 24, 2023 Posted March 24, 2023 I'm not sure what he means, is he asserting something like this? https://solarsystem.nasa.gov/moons/jupiter-moons/io/in-depth/ Quote As Jupiter rotates, it takes its magnetic field around with it, sweeping past Io and stripping off about 1 ton (1,000 kilograms) of Io's material every second. This material becomes ionized in the magnetic field and forms a doughnut-shaped cloud of intense radiation referred to as a plasma torus. Some of the ions are pulled into Jupiter's atmosphere along the magnetic lines of force and create auroras in the planet's upper atmosphere. It is the ions escaping from this torus that inflate Jupiter's magnetosphere to over twice the size we would expect.

Energy is a property, not a substance, as is conductance. Electrical energy is not attracted to conductance. 54 minutes ago, splodge said: ''On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean's waters toward it, creating one bulge. '' I suggest the waters Electrons are attracted to the moons conductivity creating the coupling and bulge . It’s gravitational. “attraction to conductivity” isn’t a phenomenon in physics. Charge is attracted or repelled by other charge, via the electrostatic interaction.

It doesn't , it travels from the Earth to the Moon across the vacuum . The vacuum of space does not conserve electrical charge , there is no vacuum impedance to prevent this happening . Only mass can conserve electrical charge . On the moon there is very little eletrical energy being produced unlike here on Earth . The Moon could be channelling Earths electrical energy and directing the oceans electrons towards the moons protons . There would be a narrow band of usefulness .

I assure you, a vacuum does not conduct electricity. https://en.m.wikipedia.org/wiki/Spark_gap “Resistance between the electrodes may be as high as 10^12 ohms when the electrodes are separated by gas or vacuum which means that little current flows even when a high voltage exists between the electrodes” 1
studiot Posted March 24, 2023 Posted March 24, 2023 I really don't see why either of these wild assed guesses (the other being that nonsence about gravity and heat) have not been move to speculations where they undoubtedly belong. They are most certainly not in accord with Physics theory, modern or classical. On 3/23/2023 at 4:21 PM, splodge said: Does there exist an ''electrical circuit'' between the Earth and Moon ? This question being based on conductance ! What do you mean by an electrical circuit ? Do you mean a complete loop or the more colloquial use of the word circuit as an assembly of electrical components ? Whilst it is conceivable that there could be an electron beam connection between the Earth and the Moon - like a giant cathode ray tube - I think that to well beyond our present technology. There is no natural process to achieve the same effect available, although we do receive natural charged particles from the Sun.

The Moon and the Magnetotail, NASA.gov: Quote [...] “Earth’s magnetotail extends well beyond the orbit of the moon and, once a month, the moon orbits through it,” says Tim Stubbs, a University of Maryland scientist working at the Goddard Space Flight Center. “This can have consequences ranging from lunar ‘dust storms’ to electrostatic discharges.” Yes, Earth does have a magnetic tail. It is an extension of the same familiar magnetic field we experience when using a Boy Scout compass to find our way around Earth’s surface. Our entire planet is enveloped in a bubble of magnetism, which springs from a molten dynamo in Earth’s core. Out in space, the solar wind presses against this bubble and stretches it, creating a long “magnetotail” in the downwind direction. Anyone can tell when the moon is inside the magnetotail. Just look: “If the moon is full, it is inside the magnetotail,” says Stubbs. “The moon enters the magnetotail three days before it is full and takes about six days to cross and exit on the other side.” It is during those six days that strange things can happen. During the crossing, the moon comes in contact with a gigantic “plasma sheet” of hot charged particles trapped in the tail. The lightest and most mobile of these particles, electrons, pepper the moon’s surface and give the moon a negative charge. On the moon’s dayside this effect is counteracted to a degree by sunlight: UV photons knock electrons back off the surface, keeping the build-up of charge at relatively low levels. But on the nightside, in the cold lunar dark, electrons accumulate and surface voltages can climb to hundreds or thousands of volts. Imagine what it feels like to be a sock pulled crackling from a dryer. Astronauts on the moon during a magnetotail crossing might be able to tell you. Walking across the dusty charged-up lunar terrain, the astronauts themselves would gather a load of excess charge. Touching another astronaut, a doorknob, a piece of sensitive electronics -- any of these simple actions could produce an unwelcome discharge. “Proper grounding is strongly recommended,” says Stubbs. The ground, meanwhile, might leap into the sky. There’s growing evidence that fine particles of moondust might actually float, ejected from the lunar surface by electrostatic repulsion. This could create a temporary nighttime atmosphere of dust ready to blacken spacesuits, clog machinery, scratch faceplates (moondust is very abrasive) and generally make life difficult for astronauts. Stranger still, moondust might gather itself into a sort of diaphanous wind. Drawn by differences in global charge accumulation, floating dust would naturally fly from the strongly-negative nightside to the weakly-negative dayside. This “dust storm” effect would be strongest at the moon’s terminator, the dividing line between day and night. Much of this is pure speculation, Stubbs cautions. No one can say for sure what happens on the moon when the magnetotail hits, because no one has been there at the crucial time. “Apollo astronauts never landed on a full moon and they never experienced the magnetotail.” The best direct evidence comes from NASA’s Lunar Prospector spacecraft, which orbited the moon in 1998-99 and monitored many magnetotail crossings. During some crossings, the spacecraft sensed big changes in the lunar nightside voltage, jumping “typically from -200 V to -1000 V,” says Jasper Halekas of UC Berkeley who has been studying the decade-old data. “It is important to note,” says Halekas, “that the plasma sheet (where all the electrons come from) is a very dynamic structure. The plasma sheet is in a constant state of motion, flapping up and down all the time. So as the moon orbits through the magnetotail, the plasma sheet can sweep across it many times. Depending on how dynamic things are, we can encounter the plasma sheet many times during a single pass through the magnetotail with encounters lasting anywhere from minutes to hours or even days.” “As a result, you can imagine how dynamic the charging environment on the moon is. The moon can be just sitting there in a quiet region of the magnetotail and then suddenly all this hot plasma goes sweeping by causing the nightside potential to spike to a kilovolt. Then it drops back again just as quickly.” The roller coaster of charge would be at its most dizzying during solar and geomagnetic storms. “That is a very dynamic time for the plasma sheet and we need to study what happens then,” he says. What happens then? Next-generation astronauts are going to find out. NASA is returning to the moon in the decades ahead and plans to establish an outpost for long-term lunar exploration. It turns out they’ll be exploring the magnetotail, too. More Information: Earth’s magnetotail isn’t the only source of plasma to charge the moon. Solar wind can provide charged particles, too; indeed, most of the time, the solar wind is the primary source. But when the moon enters the magnetotail, the solar wind is pushed back and the plasma sheet takes over. The plasma sheet is about 10 times hotter than the solar wind and that gives it more "punch" when it comes to altering the charge balance of the moon's surface. Two million degree electrons in the plasma sheet race around like crazy and many of them hit the moon's surface. Solar wind electrons are relatively cool at only 140 thousand degrees, and fewer of them zip all the way down to the shadowed surface of the moon's nightside.
