Thank you for the video. This experiment does help, but how do I apply this in controlling the Air pressure? My application demands that the air pressure be controlled up to 1 decimal. I have seen these kind of water column installations placed next to machine, but how do I hook it to machine and importantly control/vary the pressure. Could you please guide ?
It looks like the only instruments required are: - Low current amplifier (Gleichstrommessverstärker) dodo.fb06.fh-muenchen.de/lab_didaktik/at-1-1-g.htm - Analog current display The low current amplifier has extremely high input resistance, about 10^14 ohms in the case of Gleichstrommessverstärker, so it simply amplifies the current of the charged object flowing to ground and inputs it into the analog current display.
If possible, I suggest you contact the slow Mo guys to shoot the sparks through an extremely high frame rate. It will be interesting to observe at what ends are the sparks initiated as compared to the initiation and formation of lightning.
I have learned that; 1. Without anything on it, every tuning fork has the same frequency, which results in equal and comparable sound waves; and 2. Two beats have distinct frequencies. Additionally, we can hear that the sound on the left frequency is somewhat unpleasant to our ears due to destructive interference, which quickly cancels out the sound.
We work at artificial gravity devices. An electromagnetic 'decline in density' of the space adjacent to a celestial body is a good model for how gravity works. In your demo, imagine the black plastic cap (at the bottom of your glass cylinder) is a 1000 pound disk, in open space, far from any celestial body (ie no strong nearby gravity field). This is the condition of your demo when the density of the material (water) both above and below the black cap are equal, when the downward force equals the buoyant force. *_CAREFULLY NOTE_* - if you plunge the glass cylinder 3 inches deep, and only pour 1 1/2 inches of water into the glass cylinder, the average density of the material (1/2 air, 1/2 water) in the portion of the cylinder inside the water tank is less than the density of material surrounding it (water). When the lower density inside the glass cylinder is increased to match the density outside it - ie. when the submerged portion of the glass cylinder is filled with water - this eliminates the upward acceleration (the buoyant force) of the black cap. For any condition where the density of material in the portion of the glass cylinder that is submerged is less than water's density, the buoyant force is upward. Our model of gravity is a gradient decline in the density of the constituents of space, and although immense collections of atoms (ie a celestial body) can create a natural density decline, there are electromagnetic ways to achieve the same result. Just as the natural magnetic field of lodestone can be created artificially (an electromagnet). Our first device used a vertical, axial magnetic field and 16.28Mhz radial, horizontally-oriented eddy currents in a 10 layer foil lamination to attempt to alter the density of space immediately adjacent to the lamination. The Lorentz force (vertical B field, horizontal and radial eddy currents) creates coherent, acoustic waves at the 16.28Mhz frequency in the charged particles in the metal layers. Part of our effort is to seek a local effect on the density of the constituents of the dielectric known as 'space' or 'the vacuum' to create artificial gravity .
@@WonderfulDeath I have an electrical engineering and physics background. If you have developed the means to alter the electromagnetic density of a contiguous volume of space, I'm all ears. Or you're free to point out shortcomings of our ExB first device from last year, as I described it in the comment you replied. Or here's a challenge. I know the technical details of the device was deployed in the November 4, 1957 Fort Itaipu, Brazil incident that 'heated up' the two sentries in the incident. It was originally conceived by Tesla, then perfected by germans in the 1930s and 1940s. Do you know the technical details of that device? There you go, three challenges. Are you up to it? .
@@Greg_Chase i also have an engineering and physics background; don't care about your two latter challenges because they're not relevant, but there's many ways to alter the elctromagnetic density of a space. here's 10 ways, Electric Field Manipulation: By applying electric fields using electrodes or charged surfaces, you can influence the distribution of charged particles (ions and electrons) in space. This alters the electromagnetic density. Magnetic Field Manipulation: Similarly, manipulating magnetic fields using coils or permanent magnets can affect the motion of charged particles and hence the electromagnetic density. Electromagnetic Radiation: By emitting electromagnetic radiation (such as microwaves, radio waves, or light), you can introduce energy into the space, potentially altering the density of electromagnetic fields. Plasma Generation: Creating a plasma-a state of matter where atoms are ionized-can significantly alter electromagnetic properties. Plasma can be generated by heating gases or by applying high-voltage electric fields. Metamaterials: These are artificial materials engineered to have properties not found in naturally occurring substances. Metamaterials can be designed to manipulate electromagnetic waves, allowing for control over electromagnetic density in specific ways. Superconductors: Superconductors can expel magnetic fields (Meissner effect) and guide electromagnetic fields with extremely low loss. By incorporating superconducting materials, you can control electromagnetic density with high efficiency. Photonic Crystals: These are periodic structures that can control the flow of electromagnetic waves similarly to how semiconductor crystals control the flow of electrons. Photonic crystals can manipulate electromagnetic waves at the nanoscale. Dielectric Materials: By placing dielectric materials (insulators) in the space, you can alter the distribution of electric fields, affecting electromagnetic density. Waveguides and Resonators: These are structures designed to confine and control electromagnetic waves. By adjusting their geometry and material properties, you can manipulate the density and propagation of electromagnetic fields. Quantum Effects: Quantum phenomena such as quantum tunneling or the Casimir effect can influence electromagnetic properties at very small scales, providing avenues for controlling electromagnetic density.
@@WonderfulDeathNone of those methods can be used to create an acceleration field in a contiguous volume of space. I'm not saying there's anything wrong with that. It's certainly not taught. There are not degree tracks in artificial gravity. And by 'artificial gravity' I"m not referring to simulated gravity by way of rotating devices/centrifugal force. I think someone like you though, were it taught, might have pursued the topic. Good luck to you.
@@Greg_Chase you didn't ask for "an acceleration field in a contiguous volume of space" you asked for "the means to alter the electromagnetic density of a contiguous volume of space" which all of those methods can be used to create that, you shifted the goalpost. i don't think there is a viable way to create artificial gravity besides rotating devices, and even rotating devices are so impractical that the ISS refused to use them and instead had the astronauts acclimate to a zero gravity environment instead
I notice that at 1:34, when you turn off the power supply, the needle takes a moment before moving at all (longer than just the time which the current takes to get to 0, which is also not nearly instant). Why is this? Furthermore, why does the ammeter appear to show currents as high as 9.2A just before turning off completely?
Now take a look at this paper. ntrs.nasa.gov/api/citations/19840015630/downloads/19840015630.pdf Snow has a high albedo, yet has an emissivity of near 1. Something is very wrong with this method.
