the White Paper on the possibility to overcome the Betz Limit in wind power
It came to our attention that there seem to be a confusion between the Energy and the Power in our initial
paper published in Oct 2009. The corrected document is much cleaner; the
power does not intervene anymore, so we eliminated the confusion created by
using the power and the energy in our calculations.
The corrections do not change the conclusion or the
order of magnitude of Thermal energy extraction vs
Kinetic energy extraction.

White Paper on the possibility to overcome the
Betz Limit in wind power extraction
In our White Paper we
demonstrate that the wind power extraction can go beyond the Betz Limit,
without contradicting in any way Betzs Law. The ability of wind turbines
technologies to go beyond the Betz Limit will result in
future powerful wind turbines having much smaller dimensions compared to
the current large windmills.
Our recent patent application
discloses a device able to extract the wind energy beyond the Betz Limit.
Oct 4th, 2009
This year at Tesnic we have made
tremendous progress from a technology point of view.
We are proud to announce that
the Tesnic turbine incorporates now an additional efficiency increase
patent pending concept, as well as a new modular design for easier
manufacturing and installation.
Our most imperative goal is to start the commercial phase
and to offer these high efficient turbines on the market as soon as
possible. In fact we will be ready, in a 3 months
timeline, to produce the first 4kW turbines (shown in the attached picture)
as soon as we get the appropriate financing.
Unfortunately, recent unexpected and furtive financing
struggles cast a shadow on the planned timelines.
In spite of the past experiences in the financing area,
we are looking forward with confidence. We have already started discussions
with other private financing parties and hopefully these struggles will end
TESNIC technology displayed at the Environmental
Hall of Fame event in Chicago
As one of the Top 100 Clean Energy Technologies , TESNIC displayed its
technology at the Environmental
Hall of Fame event
in Chicago, from November 20th to 22nd, 2008. Our turbine raised a particular interest from the nominees and the
participants at the event.
Achieved important milestone in testing the TESNIC
We have succesfully
completed a series of tests that conducted to the optimisation of our
turbine. Moreover, the tests clearly demonstrated the tremendous effect of
the stacked disks in extracting the wind energy.
In identical tests conditions, the performances of a Darrieus
were greatly surpassed by the Tesnic
TESNIC technology displayed at the World Energy
Congress in Rome,Italy
invited as part of the Canadian delegation at the World
in Rome, Italy, from November 11th to 15th, 2007.
Once again the TESNIC technology raised great interest from the
participants all over the world.
technology exposed at CANWEA show
in Quebec City
The TESNIC technology raised great interest at the CANWEA show in Quebec City, Canada, from September 30th
to October 3rd, 2007. We have posted a video extract on the following link:
turbine @ CANWEA
We are proud to announce the completion of the first
phase of the wind tunnel tests of a 600W TESNIC turbine model. We have
posted a video extract of these tests on the following link: Wind
tunnel tests video.
After more than five months of intensive CFD simulations using the
CFX TASC flow tool, we are extremely pleased with the results and ready to
start the next phase.
The conclusion of these simulations was that the TESNIC
turbine has the ability to extract the wind power with efficiency in the
vicinity of the Betz limit.
The next step is to validate the simulation results in wind
tunnel tests, as well as in real life tests.
