1). No. Liquids turn into solid below their freezing point, except when under extreme pressure.
Which changes the capillary constraints, but then yes, capillary still occurs.
it is a function of gravity, temperature is a side effect, and will actually heat up your nitrogen.


How about those heat exchangers using liquid nitrogen or liquid argon. Are you saying that they have no surface tension at all?

2) the sterling engine electrophorus in the technisches museum
Is a heat engine. A slow moving sterling operating on ambient heat.
The Volta double electrophorus is there for show.

Have you actually built one of these? How did you know the technical details?
My point is these bicycle wheels have been spinning for 38 years. Can you use the laws of thermodynamics to predict when they are going to stop?




3) satellites are powered by fuel or by nuclear reactors and thermonuclear electric generators.
    Booster rockets navigate them into proper position for their orbits.
Without this, they fall.


For this part, I cannot comment. It seems like a political issue rather than a scientific issue.  Some countries have lost some objects in the space before and they could not get them back. Before NK sent their satellite to the vertical orbit, many thought it would not be possible. I think it also depends on the height of the orbit.

4) i think we need a lot more data before we try.

The following are two different home versions of Jones's bicycle wheel. I am not able to spot any sterling engine or electrophorus. They have been spinning for 38 years.

The museum version has been modified by Prof Poliakoff.

Each of dr jone's devices operate from energy sources all around us
That was his point.
Like Da Vinci's yard art


For example, the image in the second link (triangle shaped thing)
this has a dual-Thermoacoustic resonator driving the wheel.
we know this device today as the "free-piston sterling engine"


These devices (under normal earth conditions) will operate until
their parts break down.


In extreme conditions (mid-winter outside?) they will stop,
and return to operation when it is warmer.
Or brighter, louder, more pressure, whatever the driving mechanism is.
He used everything he could think of, to build machines that,
for all intensive purposes, perpetuate.


Energy potentials is all you need to look for.
The devices are designed to transfer the energy from one
potential to the other.


Any two points have 'some potential'.
They can be electric, thermal, physical,
magnetic, gravitational, etc.

Dr. David Jones said his spinning bicycle wheel devices were not perpetual motion.
He also said they contain various distractions to try to throw people off on how they work. 
Dr. Jones is reported to have written down how they work in a letter which was supposed to
be given to his former colleague after his death. I think he died in July 2017 or thereabouts.

All the best...

The wheel is driven by a linear motor powered by photovoltaic cells.

The simplest solution is often the best solution.
