This commentator does not agree with the fact plasma is rotating inside a tokamak. However, in plasma state of matter, electrons and nucleons separate in a magnetic field and i think we have two currents rotating in two different directions and the heavy nucleons will rotate on the outer diameter, driven by the centrifugal force.
BTW i don't agree with the fact that plasma can be "contained" with the help of a magnetic field at those temperatures. Though the gas like matter could be, the enormous temperature will radiate towards the materials of the toroidal chamber and melt it in no time.
2:43 I think here that shape is used to extract energy from Earth's potential gradient and as an antenna to catch clouds in the middle of Reno to slash the energy bill for AC in hotels and casinos and of course electricity transport networks.
Wondering if the pyramid in Vegas is of any use.

6:11 Fusion reactors. A mirage or a pretext?
It is generally agreed there is no immediate future for those. They say decades away from having free and clean energy from fusion.
Fusion is when you put together two simple atoms, like deuterium, and tritium, two forms of hydrogen, and create helium.
Though at the end of reaction we have the same number of protons and neutrons, there is a mass difference between the sum of masses of particles entering the reaction and of the resulting ones and that difference is turned into energy by the famous formula. E = mc2. C square being of course speed of light to the power of two which number is enormous, something with 16 o 17 zeroes. It is called mass deffect.
It is said mass itself contains a huge amount of energy which is true.
This so call mass defect is very hard to explain even with relativistic terms. I will leave it out of this discussion for now.
This is what happens deep inside our Sun and keeps it hot for billion of years (until all or enough hydrogen have been turn to helium etc.). No it does not explode, some say because of the enormous pressure due to gravity, some say there is not enough pressure to do just that.
Unlike fission reactors which split atoms, again aiming to turn the mass difference (defect) into energy, producing a myriad of daughters from fissionable material (fuel), extremely polluting and hard to get rid of, fusion do not produce any pollutants and deuterium is found naturally in water.
For a number of hydrogen oxygen molecules there will be one of deuterium oxygen molecule, which can be separated mechanically. Unlimited almost free clean energy. However.
And one more catch. You need a temperature of hundreds of millions of degrees Celsius to start and maintain the reaction. Deuterium and tritium atoms have to move fast enough to bump and stick together to create helium. Temperature is the measure of how fast molecules move or vibrate within a material, gas or liquid or solid.
Like anybody else. Too drown in daily mishaps to pay attention to those. Let the scientists do their job while i try to enjoy mine. Squeeze the old lemon as much as you can.
But for some reason my subconscious never, ever gave a green light to a hope in those.
However subconscious seldom gives any explanation. Possibly at some level deep buried inside our brain there is the algorithm and the myriad of information are gathered constantly and casually in a lifetime and put aside and processed to take that decision. Possibly the pessimistic and overused terms we hear about in articles.
Still they are building those in various sizes and shapes all around the world.
But time has come now to look a bit deeper, a bit beyond what surfaced in media. Cause the motivation has become obvious. There are reasonable suspicions now they are something else. In my mind suspicion arose first when looking at the temperatures. Hundreds of millions degrees.
7-10 times more than in the middle of the Sun (depending on sources). But between the core of the Sun where the reactions take place and its surface of 6000 degrees C whatever there is a 400.000 miles insulating layer of hydrogen.
Let's say you "confine" plasma with a well directed magnetic field in such ways it does not touch the walls of the structure. However, radiation from that plasma would suffice to melt those in a fraction of a second. I know, it is heat, not temperature that melts something but if there's more than an ounce of plasma in there at over 100 million degrees...
And BTW why do they need so much plasma, judging by the size of those i've seen in pictures, when they could use way less amounts at least until they're done with experimental stage?
One more thing. I know ways to produce energy for free that are already used on Earth. They are called heat pumps, which produce several times more energy than drawn from grid.
They are mainly with some rather subtle variations surprisingly simple empty toroidal volumes (empty donuts if you want) shielded with metal and/or ceramic and surrounded by a number of conductors sunk into liquid helium. The reason for that is because at ambiental pressure helium boils at only 4 degrees above zero absolute (-273.15 degrees on the Celsius scale, and -459.67 on the Fahrenheit scale).
And we all know, if something boils, like water, it will stay at boiling temperature no matter what. At ambiental pressure a liquid cannot exceed a temperature higher than its boiling point. All we need is enough helium to maintain the level (of course through boiling helium turns into gas and escapes, that is the price we pay for) to keep the conductor sank and become superconductor.
(Some would say with better results than filling balloons or inhaling to change your voice into a "heilish" one).
The conductors immersed in boiling helium loose any resistance to flow of electrons among their frozen atoms hence we can pass through enormous currents, to create enormous magnetic fields bla bla.
So here we are, building the tokamak. Looking today into them, the construction seem, as i said, surprisingly simple. A toroidal coil and a couple more i forgot what for. Through in some metal to make for the immersion pool, ceramic for heat shielding, etc..
Fill it with a bunch of plasma made of deuterium and tritium, which is basically superheated gas, to the point electrons and nuclei separate and move freely. And due to their electric charge they of course... what? What happens to an electric charge within a magnetic field?
Next question. Getting more and more confused. Is plasma moving inside a tokamak?
What i'm searching for. If there is a current of plasma looping in the tokamak. There should be at least two. One on the outside of the plasma torus, consisting of charged nuclei (just protons and neutrons, missing electrons) and one on the inside, in the opposite direction, consisting of electrons.
If you want a net current, you can get easily rid of electrons by purging or catching them somehow, maybe just at the beginning when they are not fast enough but just separated. Ground them. Pretty much like you would in magnetohydrodynamic generator.
Then you can have positively charged rotating plasma of which you can increase rotation by adding more magnetic field and make the donut of plasma stretch though centripetal force, again similarly with stretching the electric quanta moving down in squares on the gold pyramidion in the ancient devices in Giza. More elegant devices for a more civilized age.
And now we can guess what happens when you stretch a closed loop of electric current. At the level of currents and magnetic fields inside the tokamak, you can probably again crack open space itself.
12:43 Here is one in building stage. There is only one fraction or section (like an orange slice) is ready. You can realize the size of it. For what, if it will not work for decades?
