I don't believe in the principle of least action,

Reality does.

[LB7 (OP)]

no, I can't use the centrifugal force, i need to let free the axes, all axes, the spheres must be symetrical like that the centrifugal force is cancel by itself.

[Bored chemist]

What causes the gas to flow?

[Bored chemist]

" support rotates at w,"

Why?


Also,
Do you realise that the gas will have viscosity and drag ?

[Bored chemist]

but the gas can't give any torque on the support to slow down it.

Yes it does.
Did you not understand what I said about viscosity?

[LB7 (OP)]

At least in theory, i can imagine the chocs between the helix and the fluid at the perpendicular of the arm. There are only 2 lines on the helix that could accelerate the gas and accelerate the bolt. I will do the calculation even for the full helix because i think the axial accelerations are cancel by the radial, but it rest the down acceleration.

[LB7 (OP)]

It works only if the shape of the gas is perfect, the mass in the center at a dot and a perfect sphere for the shape. I suppose the wall of the helix perfect, i mean a line in the side view, mathematical walls not physical walls composed of atoms. Like that i have the 2 directions in the same time, i move of Rwt in horizontal and I move in tan(30)Rwt in vertical. I don't use the trajectory of a fixed dot on the helix because the fixed dot move in horizontal of Rwt only. The sphere that envelopp the mass can rotate because there is no mass, and it will, i don't follow the fixed dot on the helix. Like that I have the movment in horizontal and the movment in vertical. And it could explain why in the elementary particle the mass is in the center with the envelopp of a sphere. I can build a bigger device to extract the energy:a sphere and an axe in the center.

[Bored chemist]

Helium could be used, the viscosity is low I think.

"low" is not the same as zero.

[Bored chemist]

But I don't know how to calculate it. I

That seems to be just one item on a long list.
Why can't you get to grips with the fact that your idea doesn't work?

[LB7 (OP)]

I don't need a gas in rotation. I need the bolt in rotation around A1, and i need to let the bolt free around its axis A2, at start the bolt don't rotate around A2. I don't need the gas in rotation, the problem with the gas is friction. With ideal gas, no mass, no friction but a volume for each particle i have the flow too, but i can't use the mass to extract the energy but the flow by the velocity. It is like a pump which could be closed to itself, i add in the loop tube a turbine to extract the energy

[LB7 (OP)]

It is easy to realize there is a problem in the sum of energy if you compare the same device with only one difference:

1/ The nut is fixed on the support: the sum of energy is constant, at start the sum of energy lost by the support due to the nut is RFwt

2/ The nut can rotate around A2, I give the forces F1, F2 and F3 to the nut, at start, the sum of energy lost by the support due to the nut is (√3/2)RFwt

[alancalverd]

You can't destroy energy.

[LB7 (OP)]

Arf, no the sum of energy is 0, the vertical force on the bolt gives 0.375.

It is crazy, it seems it is impossible !!
