Can Wind Energy Be Bird Safe?
READ FULL ARTICLE
Nearly every week, Kimberly Kaufman receives messages from birders and conservationists alerting her to new wind energy designs that bill themselves as safe for wildlife. The technologies come in all shapes and sizes and are in varying stages of development. Yet each claims to do one thing that conventional wind turbines can’t: harness the incredible power of wind without killing birds.
Taking a Different Approach with Wind
One of the new companies is SheerWind, whose Invelox technology harvests wind energy even in areas where airflow is minimal. Invelox captures wind by funneling it through tubes that “squeeze” the wind and increase its speed, much in the same way that putting one’s finger over a garden hose will accelerate the flow of water. Then multiple turbines located inside the structure generate power from the magnified wind speed.
AUGUSTA – The Army National Guard at Fort Custer is working toward energy independence and anticipating the effects of climate change.
For at least two years the guard has been preparing a plan to use alternative energy and to look at possible consequences of changes in the environment and climate.
On Tuesday the guard provided a public look at the plan, “Adaptation Planning for Climate Resilience,” a Michigan Army National Guard pilot project.
During a series of meetings, the guard is attempting to look at long-term energy alternatives, recycling, and how it might respond to effects of climate change, according to Brig. Gen. Mike Stone, the Michigan National Guard assistant adjutant general for installations.
Stone told about 15 people attending the session Tuesday morning at Fort Custer that the guard is looking for ways to preserve resources and save money. “It is the right thing to do and it makes good business sense,” he said. Two of the most visible initiatives are a wind funnel designed to capture and increase air flow to turbine-generators and an adjacent field of solar panels.
Wind power is clean, reliable, infinite and an affordable alternative to fossil fuels. But not only that, wind energy is special and innovative! Our selection of nine miraculous wind turbines and wind farms from around the world proves that.

This 30 meter high horn is on a military base in the US state of Michigan . The wind flows through high openings inward. Turbines that are in the horn drafted generate energy. In the horn accelerates the flow, which at low wind speeds electricity can be generated.
The second church worldwide is applying the technology in the Netherlands. The municipality Goeree – Overflakkee launch a pilot project for five years. The test should show whether the technology is future-proof.
When it comes to harnessing wind for energy, Dr. Daryoush Allaei, a Purdue-trained Minnesota engineer and founder of SheerWind, thinks the industry is looking at the problem the wrong way. Current wind turbines are really only an optimized step beyond the old sail based windmills of Europe, passively waiting for the appropriate wind.
Instead, if the objective is power from wind, why not accelerate the wind for use in areas where turbines won’t work? Additionally, since conventional wind turbines kill approximately 573,000 birds annually, according to a 2015 Wildlife Society bulletin, it would be helpful to make them safer and usable in bird-filled areas like shorelines.
SheerWind’s technology is a cost-effective, high-performance alternative to conventional wind technology. By capturing, accelerating, and harvesting wind power in a funnel system called INVELOX, it turns traditional wind power systems upside down by first using a funnel to collect the wind, channeling that wind to increase its speed, and then delivering it efficiently to multiple turbines safely housed at ground level. It enables energy to be produced from very low wind speeds of 2 meters per second, in locations close to an end user — even on rooftops in urban areas —and eliminates the need for complex power and grid systems. Because the system is enclosed, it is bird-safe.
Renewable energy can come from the strangest places—and can be harvested in some of the most unique ways. This is truly evident in the recent launch of a somewhat Seussian-like wind generation station.
Generation Through Concentration and Acceleration
The funnel system—called INVELOX—harnesses incoming wind by channeling it through a funnel design that concentrates and accelerates the wind motion.

SheerWind states that this design allows for wind to be captured at speeds as low as 2 meters per second—and that it is structurally compatible enough to be built on urban rooftops.
According to an April 2016 report, the INVELOX can increase wind speeds by 7 to 12 times and create winds as high as 75 meters per second. READ MORE
SheerWind Brings Wind Funnel Technology To South Dakota
Through a new licensing agreement with Mark Luke Wind Energy LLC, Minnesota-based SheerWind’s wind power generating systems will now be marketed and deployed in South Dakota.
The agreement is SheerWind’s first of its kind in the U.S. and sixth globally. Mark Luke Cos., located in Sioux Falls, S.D., is introducing SheerWind’s technology under its renewables division.
SheerWind’s multi-patented INVELOX technology (for INcreased VELocity) turns traditional wind power systems upside down by first using a funnel to collect the wind, channeling that wind to increase its speed and then delivering it efficiently to multiple turbines safely housed at ground level.

An overseas test has revealed a technology available to New Zealand businesses is capable of producing results three times greater than traditional systems according to Pacific Wind program manager Reza Sehdehi.
This week, energy and engineering company Pacific Wind released results of a year-long study comparing the output of INVELOX to traditional wind generation capabilities discovering that not only did the INVELOX system outperform a traditional wind turbine tower it’s performance was triple that of traditional systems.
Rather than having turbines on poles in the air INVELOX systems place the turbines on the ground, using funnels to capture and direct air towards wind turbines.
Varying pipe widths in the system accelerate the wind utilizing the Venturi effect, a phenomenon used by Dyson airplane fans to deliver either cold or hot air to targeted areas.
This allowed the unit to produce 260% more electrical energy and 300% more power than traditional systems without any of the negative effects like wind noise or flickering.
“Make no mistake, INVELOX is the future of wind power generation,” says Sehdehi.
No doubt you’ve heard the phrase ‘the proof of the pudding is in the eating’. It might have first emerged in the 1920’s but it is no less true today, especially when it comes to things like technology.
Is the new technology as good as the creators say it is? Will it be up to snuff? Will it stand the rigours of the world? Is it yet another a hoax or a scam that will fail when actually put into practice?
People often seek out studies, reviews and whitepapers for good reason. They allow people to buy with the confidence that not only that new technology has no major flaws but any that minor ones have an easy solution as well.
INVELOX Review Proves Real-World Performance
Wind energy is a growing industry, with wind turbines springing up across the country. As useful as wind energy is, it has a serious downside.
Bird mortality – the large number of birds killed by the slow spinning turbine blades – has been an underreported yet critical problem. Although the exact number of bird kills is difficult to pin down, the Smithsonian’s Smart News estimated that between 140,000 and 328,000 birds die each year from collisions with wind turbines. And, it reported, taller wind turbines, while more energy efficient, offer a greater risk of collisions and fatalities.
Since that post, the company has expanded its reach, with projects and installations around the world, These include installations in Florida, The Nature Conservancy’s bird sanctuary Palmyra Atoll and multiple installations for the U.S. Army. Last month, the company’s authorized distribution HUB SheerWindChina broke ground in China for the largest INVELOX system to date – a 2.2 megawatt funnel that will include 3 turbines that are expected to have an annual energy production of over 10 million KWH.
