Anthony, studying like him in licence of physics, Nicolas Vivet built this
prototype, rather near to solar model the "3.4" described above -
and it functioned of the first blow!
Nicolas Vivet
announced me that following various tests, of condensation had been formed
inside its model, and had ended up deforming the plywood disc.
To cure this
problem, It advantageously replaced it by a plastic disc that it says to me
not to be not heavier than the precedent. It is apparently a very good idea,
especially when one does not have plywood marine at his disposal.
Below version 2 of its engine at the time of tests of operation:
version 2
turning with crushed ice
the same
one at the time of velocity measurements of rotation using a
stroboscope: 6 tours/sec are 360 tours/min!
Already
version 3!
The
most visible modification of this new engine is the addition of a
pulley on the central axis. The acknowledged goal of Nicolas Vivet
is to exploit the reversibility of the Stirling engine to produce
cold *. For that, it rotates it by an electric motor (red, with the
top of Stirling). But for the moment Nicolas Vivet considers these
results not very significant (-1,5°C) **
*
Another possible use: when the device is used out of thermal engine,
the pulley can then actuate a dynamo and convert the mechanical
energy into electric power...

Intrigued,
I hastened to adapt a small electric motor on the "model
simplified 1.1" - this electric motor consumes 100 MW with env
600 rpm, but the mechanical power should hardly exceed 50 MW...
After five minutes of rotation clockwise, I detected a difference in
temperature of approximately 1,8°C between the two plates, the
lower plate being coldest. While reversing the direction of
rotation, this difference falls to 0,3°C, the lower plate remaining
always coldest. It is possible that the energy, lost in frictions in
the slide, is the cause of this dissymmetry. It would raise the
temperature of the higher plate of a little more than one degree,
and the effect, due only to the cycle of Stirling, would be about
0,75°C - a value of the same order as the errors of measurement...
But it is true that these small Stirling engines were not designed
to this end...
One finds on the market of the generators of cold using the cycle of
Stirling, for example M77
de Sunpower. Model of entry of range, it makes it possible to
reach the sizeable temperature of 77°K (-196,15°C), but at the
cost of $33,000 without accessories, nor options!
ADVISORY: With any
technology, you take a high risk to invest significant time or money
unless (1) independent testing has thoroughly corroborated the
technology, (2) the group involved has intellectual rights to the
technology, and (3) the group has the ability to make a success of
the endeavor.
All
truth passes through three stages:
First, it is ridiculed;
Second, it is violently opposed; and
Third, it is accepted as self-evident.
