Relativist Drive

Saw in the news about the ambitions of "Musk" about building a reusable spaceship. Even if he succeeds, the current space technology is only a very expensive demonstration of the possibilities of manned orbital flight, which will carry us nowhere.

To me is more and more obvious i will never be able to patent this idea and draw any material benefits from it. And after all, it's not my idea. It is contained, in details, within the ancient symbol of caduceus.

A closed circuit with one direct straight line and two return lines in the shape of double helix that allows the flow of a heavy fluid like vapors of mercury at relativist speeds. That is close enough to speed of light so the relativist effects (increase of mass and momentum) takes place.

In one way or direct way, in the line figured by the stick in the middle in the first image the fluid goes at full relativistic speed respect to a coordinate system with x axis parallel with the stick and the other way, or return way or the two lines figuring a double helix, the component of axial speed or projection of speed on x axis in the same coordinate system is at one order of magnitude smaller than te full speed in the direct line thus there is no significant relativist axial component of momentum. The difference in relativistic axial momenta of fluid circulating in the direct and return lines will create a net momentum.

Easier. Imagine this. One larger cylinder containing a smaller (let's say 10 times the volume) cylinder inside, both of similar lengths and some means to accelerate the fluid inside the smaller one at relativist speeds. In the smaller cylinder the fluid circulates in one direction at higher relativist speeds than the relativist speeds in the larger one in the other direction. Will you have a net momentum from a closed circuit asymmetric relativist drive?

Yeah i know just read on forums, it is said that moving matter at relativist speeds also increase the temperature by the same formula as momentum (and mass) and that in the case of a gas like described above will leads to unmanageable temperatures even before reaching relativist speeds.

However i have some questions in my mind about that. Temperature does not exist per se or is a property of matter, like mass is (that increases by the same formula at relativist speeds). In a gas is a measure of the average moving speeds of molecules in random directions. When all molecules are moving aligned together at relativist speeds in vacuum in one direction like in LHC can we still talk about temperature?

BTW could mass defect be accounted for by the differences in speed of electrons moving in orbit at relativist speeds? The bigger the nucleus, the higher the orbits, the lower the speeds.
