This
is a serious contender for wind energy aforethought the real obvious
problem is how to handle extreme winds.
I
would attempt to build a larger device and to extend the height to
ensure that the exit tube remains vertical and surrounded by the
tower structure itself. I would then attempt to actually design the
funnel component out of retractable sails to allow retreat in the
face of extreme winds. Then if we are doing all that anyway it may
be possible to set up a simple arced spar pair and forms a capture
vee for the rising sail to naturally expand its capture area as it
extends. Of course is would also naturally rotate into the wind. It
should work as well if not better that the present design concept.
Even
better the design may allow internal controlled adjustment and
computer optimization also. It could easily behave like a gorgeous
flower.
SheerWind Reports
Its Commercial-Grade Field Unit Significantly Outperforms Traditional
Wind Generation and is Competitive with Natural Gas and Hydroelectric
Generation
February 20, 2013
MINNEAPOLIS--(BUSINESS
WIRE)--SheerWind, Inc., an innovator in high-performance,
cost-efficient wind energy technology, announces initial
field-testing results, which comparesINVELOX commercial-grade
wind energy generation with the same turbine on a traditional
tower-mounted system. The test results indicate
that INVELOX significantly outperforms the traditional
turbine and is competitive with natural gas and hydroelectric
generation by:
- Producing 600% more electrical energy (kWh)
- Operating at wind speeds as low as 1 mile per hour and in low wind regimes (class 1 and 2)
- Reducing installation capital cost to less that $750 per KW
- Increasing energy production capacity to record high of 72%
“This exciting
performance superiority over traditional wind and competitiveness
with natural gas and hydroelectric generation is attracting
significant interest from Fortune 500 and moderately sized companies;
government entities; industry experts; and others,” states Dr.
Daryoush Allaei, CEO of SheerWind, Inc. “Our ability to operate
efficiently and effectively in areas never considered viable with
traditional wind energy and at costs as low as $10 MWH makes
SheerWind a true game-changer in electric power generation.”
SheerWind’s INVELOX wind
energy system captures the breeze from an above ground portal and
funnels the wind through a tapering passageway that naturally
accelerates its flow. This kinetic energy drives
the INVELOX generator that operates at ground
level. INVELOX has the following advantages:
- Costs less than 1 cent per KWH, making it competitive with natural gas and hydroelectric powered generation
- Requires no government subsidies to be profitable
- Reduces operating cost by 50% of current wind turbine technology
- Minimizes environment, animal, bird and human impact
About SheerWind, Inc.
SheerWind’s
breakthrough wind technology is changing the course of power
generation. The patented INVELOX electricity generation
technology operates efficiently at wind speeds as low as 1 mile per
hour, requires no government subsidies, is price competitive with
traditional energy and has far less environmental impact than
traditional generation technologies. The US electric power generation
market is $250 billion and globally exceeds $1 trillion. The high
performance and efficiency capabilities of INVELOX offer a
global renewable energy solution that easily integrates with the
power grid for small and commercial operations. For more information

How it Works
Capture, accelerate,
concentrate. These three words express the essence of SheerWind’s
approach to wind power. The name INVELOX comes from this dedication
to INcreasing the VELOcity of wind. What the technology
produces—energy that is affordable, abundant, safe, and clean—is
nothing short of revolutionary.
Conventional wind
turbines use massive turbine generator systems mounted on top of a
tower. INVELOX, by contrast, funnels wind energy to ground-based
generators. Instead of snatching bits of energy from the wind as it
passes through the blades of a rotor, wind is captured with a funnel
and directed through a tapering passageway that naturally accelerates
its flow. This stream of kinetic energy then drives a generator that
is installed safely and economically at ground level.
Bringing the airflow
from the top of the tower to ground level allows for greater power
generation with much smaller turbine blades. It also allows for
networking, allowing multiple towers to direct energy to the same
generator. The unit is about 50% shorter than traditional wind towers
and uses a ground-based turbine with blades that are 84% smaller.
Fewer generators are required, so equipment and maintenance costs are
lower. Most importantly, energy output is greater.
INVELOX is scalable,
equally suitable for use in major wind farms or micro-generation
settings. It will produce power effectively at much lower wind speeds
than current systems do, which means it will have a dramatically
wider geographical range of use.
SheerWind’s value
proposition is clear: facilitating inexpensive, efficient power
generation with less impact to the environment and surrounding
community.
Technology Validation
INVELOX technology has
been reviewed and validated by a technical advisory board, a team of
experts from major research universities and agencies. Prototypes
were tested under controlled laboratory conditions, and test results
were used to build and validate full-scale computational fluid
dynamic (CFD) models.
Several demonstration
units are being field tested during 2012. The first small-scale unit
was installed in a field near SheerWind’s facility in Chaska,
Minnesota. The unit incorporates the instruments for full speed and
power data collection. Preliminary speed data have validated CFD
model predictions.
A larger-scale
(Commercial-grade) field demo unit has also been completed. Data
collection and testing has exceeded expectations.

Not promising, just seriously overhyped. The Invelox is a misleadingly represented wind generation device that likely gets 18 times worse generation, not six times better. Orders of magnitude of misrepresentation. Full analysis here:
