Two Swiss Gearlooses, Mr. Karl Bahnmüller and Mr.
Patrick Richter, have invented the wind tower, and
we wish them good luck in getting it ready for
series production. Who invented it? The Swiss. Seek
and you shall find!

<By Christoph Landolt.
Two people from Zurich want to produce electricity
around the world with their wind towers. Energy
specialists consider their concept worthy of
consideration.>
The Agile
wind tower by Karl Bahnmüller and
Patrick Richter
The wind tower with a
horizontal wind mill inside by Karl
Bahnmüller and Patrick Richter [1]
The
comparison between wind
turbine and wind tower,
scheme: The Agile wind tower
needs only 1/3 of the space,
in combination with a
generator and electricity
storage on the ground and a
compressed air tank for wind
in peak periods. [2]
The
wind council in the wind tower
has adjustable rotor blades,
scheme [3]
<Egon Lang, professor of energy technology at
the Zurich University of Applied Sciences (ZHAW),
was also skeptical at first. "Vertical wind power
plants are nothing new; their advantages and
disadvantages have been known for decades." There
are good reasons why the rotors of conventional
wind power plants rotate around a horizontal axis
at a lofty height: Higher is better. At 150
meters, the wind blows much stronger than further
down, where the rotors of vertical wind towers
turn. The technical literature therefore says that
vertical models can achieve at most 75 percent of
the efficiency of horizontal wind turbines.
Karl Bahnmüller and Patrick Richter, the two
inventors behind the company Agile Wind Power AG,
want to turn the market for wind turbines around.
They have also presented their idea to researchers
such as ETH Professor Lino Guzzella or Lang from
the ZHAW. The latter has great confidence in the
inventors: "The concept is promising." Richter and
Bahnmüller can't outsmart physics, but their
concept has some additional advantages, as Lang
explains in an interview with Tagesanzeiger.com.
Also a battery
[Rotor + generator on the ground + compressed
air tank].
Countless engineers have tried their hand at
vertical wind turbines, with manageable success.
In 1925, for example, Finnish naval officer Sigurd
Savonius developed a system using rotors shaped
like tubes cut in half. Frenchman George Darrieus
patented his system five years later, in which
rotor blades converge in an arc at the top and
bottom of the shaft. Both systems work, but
provide little power.
Richter and Bahnmüller believe the Agile wind
tower can catch on. Unlike horizontal-axis wind
turbines, the generator is not housed in a nacelle
a hundred meters up, but on the ground. This not
only makes maintenance easier. "We plan to combine
the wind tower with an energy storage system,"
Richter says. Instead of feeding electricity
directly into the grid, Richter wants to compress
air into a tank [compressed air]. When energy is
in demand and prices are high, the compressed air
could be turned into expensive peak electricity.
This, according to ETH professor Lino Guzzella, is
the real strength of the Agile system. Wind power
plants supply energy only 40 percent of the time,
and this can be efficiently stored with compressed
air.
Folding rotors
"The idea is ingenious," says ZHAW professor Lang.
But the coupling with an energy storage system is
not the only innovation that Richter and
Bahnmüller want to help achieve a breakthrough.
Also new is the idea of changing the position of
the rotor blades during rotation. Richter and
Bahnmüller have patented this system worldwide.
"In vertical wind turbines, one half of the rotors
moves with the wind, while the other half moves
against it," explains energy specialist Lang. In
conventional models, this causes a lot of energy
to dissipate.
By setting the rotor blades in the style of an
airplane wing or a sail, the two inventors can
solve this problem. The blades in the wind are
positioned transversely to maximize drag.
Meanwhile, the other blades, which move against
the wind, are pitched to create lift. Lang
compares to a sailing ship that can also be
steered against the wind.
However, the two professors also see this folding
mechanism as the biggest obstacle for the Agile
wind tower. They fear that the service life of the
parts is short because of the flapping motion. In
any case, it is worthwhile to continue the
development, says Guzzella. Ultimately, however,
the technical design will determine whether the
new vertical wind turbine stands a chance against
conventional models, he says. "Today's power
plants already use the wind very, very well."

Switzerland 1.8.2011: Preparation
for the small wind turbine on a farm in the Frick
Valley: The wheel of time turns with the wind (orig. German: Das Rad der Zeit dreht mit dem
Wind)
http://bazonline.com/basel/land/Das-Rad-der-Zeit-dreht-mit-dem-Wind/story/19638916
A small wind turbine like this one should also
generate energy in Frick Valley [4]
<By Franziska Laur.
On a Fricktal farm, the rough wind will soon be used
to produce electricity - with one of Switzerland's
first small wind turbines.
Such a wind turbine is soon to be mounted on the
roof of the riding arena in Zeiningen.
Anyone who visits the Schib family's Tschopperthof
in Zeiningen from time to time knows that a rough
wind blows there. Literally. And Erich Schib wanted
to take advantage of it. "My father said 30 years
ago that the constant wind on the farm had to be
used," he says. That's why a small wind turbine is
now to produce electricity on the roof of the riding
arena.
Recently, the favor of the hour beckoned. The family
heard of an electrician on the German side who
supplies and installs such wheels - at an affordable
price of just over 7000 euros. Now the building
application is still open until August 8.
Legal obstacles
In Switzerland, it is one of the first small wind
turbines of this kind to be installed. But this
could soon change. "Since Fukushima, demand has
skyrocketed," says Dirk Süss of Enflo Windtec in
Kreuzlingen, which distributes the wheel. Until
now, the company has delivered mainly to Germany,
Spain and the Benelux countries. Depending on
local wind strength, the product can supply
one-quarter to one-half of a normal household's
consumption, Süss says.
But because the Schib family's indoor riding arena
is outside the building zone, the canton must also
give its blessing for the wind turbine to be
installed. At the Department of Construction,
Transport and Environment of the Canton of Aargau,
it is one of the first building applications for
such a micro wind turbine on the table. "In
principle, we support the use of renewable
energies," says Sascha Amhof, section head of the
department for building permits. In the case of
Zeiningen, a site outside the building zone is
involved. "Zoning conformity for wind turbines
outside the building zone cannot be affirmed."
Therefore, no ordinary building permit could be
granted.
However, since a property already exists in the
present case, the right to grandfathering applies.
In addition, there are no overriding interests
against the construction of a micro wind turbine,
especially since it is hardly noticeable in the
landscape and is mounted on an existing building
similar to a solar system. Thus, one could say yes
to such an application with a clear conscience.
The final decision, however, lies with the
municipality. According to Zeiningen's municipal
clerk Marius Fricker, the municipality is also
open to the request.
Solar power is sold
Two years ago, the Schib family had the roof of
the riding hall fitted with a photovoltaic system.
This is 430 square meters in size and, with its
32,000 kilowatt hours per year, covers the
consumption of eight to ten households. The family
has invested around a quarter of a million francs.
"I sell this production. But since we need quite a
lot of electricity on the farm, we also wanted to
contribute to our own electricity consumption -
hence the wind turbine," says Erich Schib.
The environmental science graduate manages the
farm and the boarding horses with his wife Nicole,
father Robert Schib lends a hand where necessary
and breeds horses, and brother Dieter Schib gives
riding lessons. And there is one thing in
particular that makes the Tschopperthof so
appealing: the love of nature is not just talked
about, it is lived every day. (Basler Zeitung)>
Altstätten (Switzerland,
St. Gallen) 10.3.2014: Wind generator
with wind buckets "Aroto" - combined
with solar plant optimal Self-developed:
Clever wind generators from the Rhine Valley;

World
first from the Rhine Valley: An SME
produces compact wind turbines for
self-sufficient power supply. The main
customer is to be Africa.
The wind turbines produced by G&S World
Bridge Trading in Altstätten weigh a light
250 kilos. They supply electricity at a wind
speed of just 10 kilometers per hour - in
other words, a light breeze. Compared to
conventional wind turbines, the small energy
factories have several advantages, according
to the manufacturers: The frost- and
heat-resistant Aroto produces energy
regardless of wind direction - and thanks to
so-called "wind spoons," it's also
completely silent. And while wind turbines
have to be shut down during storms, an
"Aroto" simply keeps working.
"Anyone who mounts three Arotos on their
roof will have a completely self-sufficient
supply of electricity," says CEO Georges
Gamper. This is interesting for countries
without a functioning power grid, such as
South Africa: "There, an Aroto pays for
itself within three years," says the
61-year-old.
Farmers' associations in South Africa have
already assured him that they will buy large
quantities. The Rhine Valley innovation is
also set to triumph in other countries such
as Nigeria. The Aroto can be supplemented
with solar panels as desired. "This is ideal
for Africa in particular," says Gamper.
Everything produced in-house
The Altstätt-based company produces the 35
different system components in-house. "We
don't want to be dependent on suppliers,"
explains the trained carpenter.
Everything from the wind bucket to the
generator was developed in Altstätten.
Gamper's business partner Sigfried Schmitt
had the idea six years ago. At that time,
the two founded their company, with the
vision of a self-sufficient wind power plant
already clearly in mind. In April, they want
to go into series production with it.
Gamper: "Soon we will be producing 1000
units a month." The price of an Aroto module
with nine wind spoons is 8600 francs.
The first system is already in operation on
the roof of a house in Widnau. "I expect
this combined system to supply around half
of our electricity needs," says the
homeowner.

This admittedly somewhat odd-looking
turbine actually has the potential to revolutionize
wind power technology! We are talking about Vortex
Bladeless! (Source 1) Rotor blades, as in
conventional wind turbines, this wind power
technology does not have. Also there is no gear, no
generator in the actual sense and also no brakes!
(Source 2) The current is won by oscillation. The
plant swings in the wind! (Source 2) To the use one
makes oneself a phenomenon called vortex-induced
oscillation. (Source 3) According to fluid
mechanics, the flow of wind is modified by striking
a blunt body. A cyclic vortex pattern is formed.
(Source 2) However, as soon as the frequency of
these forces is close enough to the structural
frequency of the blunt body, the body begins to
vibrate quite violently and enters into resonance
with the wind, as seen here on the lanterns! (Source
2, 3) This is exactly what we want to avoid at all
costs in architecture with e.g. high-rise buildings
or bridges. The buildings would be at high risk of
collapse. Here with the wind power engineering,
however, this oscillation supplies us with current!
(Source 2)
The calculation: The current by the vibrating rod of
Vortex is cheap, because it applies:
-- minimum area consumption
-- uses also weak winds from 2 to 8m per second,
where the big windmills still stand still
-- exploits also the small winds on the ground
-- cheap and light materials
-- hardly any transport costs
-- no technically complicated parts
-- hardly any repairs
What does the Vortex website say?
https://vortexbladeless.com/
-- Low maintenance costs
-- Harmless to wildlife, no damages
-- there are no complicated mechanisms: Gears and
brakes NO
-- Needs oiling NO
-- Self-running & standalone without control
-- Lightweight, minimal need of raw materials
-- Can handle all winds from all directions: Quick
response to wind changes.
