ITER - Assembling a million-component machine

The ITER tokamak consists of 15 major sub-systems, some 300 very large elements — 1 200 tons for the heaviest of them — and approximately one million components. Such a complex machine, says Robert Shaw in this video interview, "has never been done before."

So let's join ITER's Machine Assembly and Installation Section Leader as he explains how to assemble this unique million-component machine, and presents the tools that will make this task possible.

second comment.... So in the Tokamak you need to induce current into the plasma to turn the plasma itself into a magnetic coil for confinement. Watch this: watch?v=eftWIDeMAHI That is the design of the Wendelstein 7-X, here you only need external coils and no current in the plasma, because at 5 locations particles following the outer trajectories can go deeper into the confinement. So this can work without the leaks haunting tokamaks.

check Wendelstein 7-X and its predecessor Wendelstein 7-as. In that reactor design, the stellerator, the confinement is better than in a tokamak, it doesnt leak, and its accomplished only by external magnets. No current is being induced into the plasma torus in the stellerator design. The disadvantage is that the magnetic field is far more complicated, less symmetrical, not a simple torus but a twisted torus. Also, the reactor is bigger, a larger but thinner torus.

well, tokamaks will always leak, but they can still produce more energy than you put in. The confinement isnt perfect.

But there is a different design, the stellerator design, Wendelstein 7-X is currently being assembled. Here the confinement is perfect and doesnt leak, but the magnetic field is far more complicated and less symmetrical. If ITER fails because the confinement isnt good enough, Wendelstein 7-X is the alternative.

the plasma in the sun is NOT magnetically confined. Its confined by gravity. The magnetic fields of the sun dont matter much when considering the nuclear fusion processes in the sun.

Also, at one locatiopn, you can only have one magnetic field. field lines dont cross the way you describe it. Basically there is only one big magnetic field in our universe that you can locally manipulate, two fields never overlap, never, nowhere in the universe.

I have invented not these opinions, I have made only a logical, rational and intuitive synthesis, having at base, in majority experimental, observed and demonstrated arguments. I have not something against ITER, but against the utopian conceptions from the theoretical physics, with which are indoctrinated those 3000 of engineers and physicists involved in the realiozation of the thermonuclear controllable fusion.

The texture of toroidal, poloidal or stellarator magnetic field is too rare for to form a magnetic trap. The magnetic trap must let be one electromagnetic stratified wall with weaved at entrance and with disweaved at emergence. The electromagnetic wall of the magnetic trap is a wal with formation and continuous displacement.

The Sun has two sorts of magnetic fields:1)-the principal magnetic field of the solar magnetosphere which dress the solar mass; 2)-the secondary magnetic fields which pass through the whirligig tubes by one hemisphere in another. Because the rotation of the solar mass the lines of the secondary magnetic fields are not parallel with the lines of the principal magnetic field, but are adjacent and thus it form at surface of the Sun a texture of magnetic lines, as a magnetic wall.

Now the ITER can not be a makerstars, because the his specialists know not how work the Sun with his principal componets. In outside of incandescent solar mass exist: principal magnetic field(solar magnetosphere with magnetic trap); secondary magnetic fields(made by the whirl's tubes); radiations belt; the "butterfly" diagram(with solar spots positions in the ends of the whirl's tubes, which pass through the solar mass); whirl's tubes pressure; magnetic pressure by principal...

The connditions of thermonuclear controlled fusion: temperature, concentration, confinement and duration - can not obtained never in a tokamak installation, because the her incapacity of the magnetic trap, which can not dress and surround whole the thermonuclear plasma. The plasma can not restrained, can not be maintained and thus can not be heating. Till now 2011 - it confined not the plasma on the tokamak installations.

The Sun shows us how it prepare and how it produce the thermonuclear reaction, and the resonant generator of the Tesla shows us how it can extyract the electricity - the particles of the electrical ether, without to utilize the switchs of heat. The ethereal explanation of the phenomenon is necessary because in outside of electricity= electrical ether, all ethereal substances are: the electrons. the inductive magnetic field, as and the electrical field.
