Another deep thot I had about an electrical generator:

In short, imagine the following:

A sealed glass donut shaped container which has two mixed fluids of different boiling points, one being high and other one very low, and also has pyrolytic graphite suspended in the mixture of fluids, with a copper coil wound around the sides of the donut perpendicular to the position of a magnet in the center of the donut with respect to its polarity. The low boiling point of one of the fluids due to temperature change causes the whole mixture to turn around inside. The circular shape of the walls of the donut shaped container promotes the circular motion. The space between the magnet which is inside the donut shaped container hole, and the outside of the magnet where the coil is wound around, contains the mixture of the fluids which is moving around and the diamagnetic pieces of pyrolytic graphite are making the field intermittent. This should enable the production of electricity in the coil. The fluid would be black so to collect the heat and the pyrolytic graphite is also an excellent heat conductor which is a bonus to improve efficiency. As the fluids separate and one turns to vapor then condenses back into the mix the pyrolytic graphite causes disturbances in the magnetic field by blocking it which the coil takes as changes of magnetism and can be collected as energy.

Moar explained:

A donut-shaped container that is transparent and sealed that contains two fluids. There is a small air pocket in the container to allow for the vapor to expand and condense back into a fluid. The fluids are mixed together and a fine powder of pyrolytic graphite is added. The pyrolytic graphite is added to the mixture for it’s strong diamagnetic property.

Inside the hole of the donut-shaped container is a cylindrical shaped magnet. North Pole is on the top of the cylindrical shaped magnet and vice versa. The top of the magnet faces up if you were to be looking down at the donut from above.

A mixture of two fluids, one having a low boiling point and another having a much higher boiling point. The mixture is also black to absorb the maximum amount of heat. Let’s call these LBP liquid and HBP liquid as reference. Let’s also say that the LBP liquid turns to vapor at 95 degrees Fahrenheit Post too long. Click here to view the full text.

>The low boiling point of one of the fluids due to temperature change causes the whole mixture to turn around inside

Explain this part better. How does the temperature change make it move around?

>A donut-shaped container that is transparent and sealed that contains two fluids.

Sealed and made of glass. Does it have to be transparent?

>The fluids are mixed together and a fine powder of pyrolytic graphite is added.

The mixture will have a temperature range between its saturated liquid and saturated vapor states and will be between the boiling point of the original 2 liquids.

>The coil is wound around the sides of the donut shaped container horizontally.

Describe this coil better. Does it cover the transparent container?

Yeah, I wouldn't really know but I've seen brainwave graphs like from https://www.bibliotecapleyades.net/esp_autor_winter.htm

There have been experiments in using magnetic fields to change workings of the human body, but most of those are unverified as to the results. Supposedly wearing certain rings with magnets in them can enhance or inhibit proper function depending which way the magnetic poles are faced.

I know there have been experiments with magnets and possible therapeutic uses with patients with MS.

One involves static magnets and another involves 'pulsed' magnetic fields.

I guess we could have a thread about that and DMT

Psilocybin is a nervous system chemical from certain mushrooms which can be disruptive for human nervous systems.

Yes practical applications. Benchmarking/record stuff is mostly for the scientific community/science fags (nothing like PC benchmarking stuff). Lasers like above can have industrial, entertainment, maybe medical at lower power and other applications which I can't really get into..

Some common industrial applications may include PCB trimming, solar cell scribing, ablation, engraving, plastic cutting. Others in other wavelength ranges can do other things. One project is a high power laser for a vacuum chamber, for a new approach to physics and material generation.. one of the more interesting ones. When I have more public information I will share it here as I think the board will enjoy it.

/robowaifu/ here. This is an interesting tech, and is actually (kind of) real now. I applied for an engineering position with a DoD contractor in Austin TX as a GPU programmer. They were using a custom table with a spinning reflective surface projecting images using NVidia GPUs.

I think a VR approach will have to serve for typical anons in any nearterm scenario tbh, and it's one we are interested in over at RW, particularly for the Visual Waifu bread.

These are the number codes

If you look at seven segment displays and look at those numbers they would seem pretty random for someone who doesn't know the number representations, I mean there are only 7 segments there but we use them for a 10 number system.

This one could also be used with individual segments representing the 10 digits from 0 to 9 so it offers a lot of options. Since it has 10 segments it also effectively works as a new sign language, since we have 10 fingers

The sides of the panel are lit up with lights like LED's. This gives the effect to lit up the drawn colors on the transparent panel, which is a pretty cool effect. Pic related
