Rochester, NY – December 2, 2009 –
WindTamer Corporation (OTC.BB.WNDT-News) today released the results of a performance report from Professor Kenneth Visser of the Department of Mechanical and Aeronautical Engineering at Clarkson University in Potsdam, New York. The report is based on an analysis of field testing in the Geneseo, New York area and numerical modeling at the Clarkson University.
Gerald E. Brock, WindTamer’s founder, Chairman, Chief Executive Officer and Inventor of the patented WindTamer technology, said, “We are gratified but not at all surprised by the results of the Clarkson University study. We have known for some time, based on our own testing, that WindTamer will outperform its competition by a wide margin. We have also known that WindTamer can produce energy well above the Betz Limit, which has always been viewed as the theoretical limit of the percentage of power that can be extracted from wind moving through a turbine. It should also be noted that the hubs of the WindTamer units that produced these results were only 13 and 24 feet off the ground, which makes WindTamer an extremely attractive alternative to the huge wind towers that are seemingly unwelcome in some communities. The fact that a prestigious research institution such as Clarkson University and a widely recognized, highly respected researcher such as Dr. Ken Visser have now verified our findings is an important seal of approval.”
William A. Schmitz, President of WindTamer Corporation, said that, “From a sales and marketing point of view, this report reinforces our essential message, which is that individuals, businesses, wind farm developers and other purchasers of wind turbines have a new alternative that is not only efficient enough to make economic sense but is also whisper-quiet, less susceptible to wear and fatigue and safer than many turbines currently in use.”
If you do a search for wind turbines that beat the Betz limit, the WindTamer Turbine tops the list, and does so with some nice videos. (There seems to be an inverse correlation between video production and idea quality…) As these videos claim to beat the Betz limit, the theoretical maximum efficiency for a wind turbine which most informed people believe is an absolute limit, the WindTamer Turbine warrants some discussion.
Taking a look at the youtube video purporting to explain how the turbine beats the limit. What we see is a high-solidity (lots of blades) turbine inside a duct with a large diffuser extending behind it. The video explains that the diffuser creates a vacuum behind the turbine which increases the air flow through the rotor, boosting the power output. Fair enough. I wouldn’t say “vacuum”, but that all makes sense.
But then the video claims this arrangement produces double the aerodynamic efficiency of conventional turbines and beats the Betz limit. I don’t believe it.
If you’re not familiar with the Betz limit, here’s the gist of it (WindTamer Corp. might want to pay attention too). Picture a hula-hoop held in the air with wind blowing through it. There’s a certain amount of kinetic power in the wind passing through the hoop. If we put a wind turbine in the hoop, the wind turbine can capture some of the kinetic power passing through the hoop by slowing the wind down. The wind turbine can never take all the power flowing through the hoop because that would entail stopping the wind entirely, in which case there would be no wind to spin the turbine. Aerodynamic efficiency refers to how much of the power passing through the hoop the wind turbine captures. We know that to take all of it (100% efficiency) is impossible. So how much is possible? The backing math can readily be found on the web, such as here, but the answer is 16/27 or ~59%. This theoretical maximum is called the Betz limit.
Calculating a turbine’s actual efficiency is easy enough. You simply measure the power produced by the turbine, and divide it by the power of the air that would flow through the hoop if the turbine wasn’t there. As you’ve probably already figured out, this only makes sense if the hoop is the same size as the turbine. If the hoop doesn’t perfectly surround all the wind that the turbine is slowing down, then the number is meaningless. You can pick any hoop size you want, and get any number you want, but it won’t be a measure of aerodynamic efficiency!
This is the error (I’m not sure that it’s a mistake) that WindTamer conveniently makes. The figurative hoop in their calculations is only the size of their turbine’s rotor, rather than the size of the huge diffuser on the back of the turbine that is providing part of the power. If WindTamer balanced their books properly by accounting for the full area of their turbine in their efficiency calculations, we would see that their efficiency is in fact quite modest, and significantly less than the Betz limit.
For a more detailed critique of the WindTamer efficiency claims, have a look at Paul Gipe’s writeup. This sort of convenient flaw is common of a lot of unconventional wind turbine developers, unfortunately. As far as I’m concerned, anyone proclaiming to have beaten the Betz limit is either being deliberately dishonest or lacks a solid understanding of what aerodynamic efficiency means.
Despite the shiny prototypes and the still-popular youtube videos, it seems that WindTamer has for the most part disappeared into the woodwork, as most sketchy power device developers eventually do. There’s no WindTamer Corp website to be found. But it seems the technology has been licensed or sold to Arista Power, who’s website is advertising the turbines using the same false performance claims as found in the videos.

Equilibrado de piezas
El equilibrado representa una fase clave en el mantenimiento de maquinaria agricola, asi como en la fabricacion de ejes, volantes, rotores y armaduras de motores electricos. El desequilibrio genera vibraciones que incrementan el desgaste de los rodamientos, provocan sobrecalentamiento e incluso llegan a causar la rotura de componentes. Con el fin de prevenir fallos mecanicos, es fundamental identificar y corregir el desequilibrio de forma temprana utilizando metodos modernos de diagnostico.
Metodos principales de equilibrado
Existen varias tecnicas para corregir el desequilibrio, dependiendo del tipo de componente y la intensidad de las vibraciones:
El equilibrado dinamico – Se utiliza en componentes rotativos (rotores, ejes) y se lleva a cabo mediante maquinas equilibradoras especializadas.
Equilibrado estatico – Se usa en volantes, ruedas y otras piezas donde basta con compensar el peso en un solo plano.
Correccion del desequilibrio – Se lleva a cabo mediante:
Taladrado (eliminacion de material en la zona mas pesada),
Instalacion de contrapesos (en ruedas, aros de volantes),
Ajuste de masas de equilibrado (como en el caso de los ciguenales).
Diagnostico del desequilibrio: equipos utilizados
Para identificar con precision las vibraciones y el desequilibrio, se utilizan:
Equipos equilibradores – Miden el nivel de vibracion y definen con precision los puntos de correccion.
Analizadores de vibraciones – Registran el espectro de oscilaciones, identificando no solo el desequilibrio, sino tambien otros defectos (como el desgaste de rodamientos).
Sistemas laser – Se usan para mediciones de alta precision en mecanismos criticos.
Especial atencion merecen las velocidades criticas de rotacion – condiciones en las que la vibracion se incrementa de forma significativa debido a la resonancia. Un equilibrado adecuado evita danos en el equipo en estas condiciones de funcionamiento.

폰테크
폰테크라는 방식은 급하게 현금이 필요할 때 자주 검토되는 수단으로 언급됩니다. 요즘은 비대면 진행, 당일 입금, 미납요금 대납, 전국 상담 같은 요소가 같이 노출되면서 안내 문구도 늘어났습니다. 하지만 검토할 때는 빠르다는 말보다 진행 구조를 먼저 봐야 합니다. 접수 방식, 진행 형태, 입금까지의 흐름을 먼저 확인하는 편이 낫습니다.
비대면 방식의 폰테크는 방문 없이 상담, 접수, 진행 안내까지 상당 부분을 원격으로 처리하는 형태가 중심입니다. 수도권뿐 아니라 강원도, 충청도, 전라도, 경상도, 제주까지 전국 단위 상담을 내세우는 경우도 많습니다. 이동 부담이 적다는 점은 장점이지만, 절차가 단순해 보일수록 조건 확인은 더 정확해야 합니다.
폰테크나 가개통 안내에서는 당일 진행, 당일 입금, 24시간 상담, 연중무휴 같은 문구가 자주 보입니다. 중요한 것은 표현보다 실제 진행 방식입니다. 어떤 기종을 다루는지, 조건이 어떻게 정해지는지, 어떤 방식으로 진행 가능한지, 입금 시점이 언제인지까지 확인돼야 합니다.
진행 흐름은 대체로 비슷합니다. 전화나 문자, 카카오톡으로 상담을 시작한 뒤, 조건과 기종을 확인한 다음, 방문·출장·비대면·대납 중 방식을 선택하고, 기기 수령 뒤 바로 지급으로 이어지는 방식입니다. 겉으로는 단순해 보여도 단계마다 체크할 부분은 다릅니다. 특히 상담 단계에서 본인 상황에 맞는 진행 형태와 가능 조건을 분명히 해야 뒤에서 꼬이지 않습니다.
전국 서비스를 내세우는 곳들은 서울부터 제주까지 세부 지역명을 길게 배치하는 경우가 많습니다. 이런 구성은 지역 검색에 강하고, 사용자에게 해당 지역에서도 진행 가능하다는 인상을 줍니다. 지역명과 서비스명을 붙인 표현이 반복되는 이유도 여기에 있습니다.
상담 채널은 보통 대표전화, 카카오톡, 상담신청 버튼처럼 바로 연결되는 구조로 잡힙니다. 보통 이런 채널 옆에는 신속 진행이나 1:1 상담 문구가 함께 배치됩니다. 다만 판단 기준은 광고 문구가 아니라 운영 정보와 절차 설명입니다.
요약하면 핵심 포인트는 세 가지입니다. 현금이 급할 때 빠르게 검토할 수 있다는 점, 비대면과 전국 단위 상담이 가능하다는 점, 절차 흐름이 비교적 단순하다는 점입니다. 이용자 기준에서는 빠르다는 말보다 조건과 절차를 먼저 보는 편이 맞습니다.

The Contradiction of an Australian Cigarette Website: Health Advice vs. Sales
A website has appeared offering customers in Australia the opportunity to buy tobacco products with delivery to their door. The website, which goes by Australia Tobacconist Hub, presents a striking contradiction: aggressive marketing of budget tobacco products alongside formal warnings about the dangers of smoking.
What the Service Offers
The platform’s key target audience is people who smoke looking to save money. Key items on the price list include:
Double Happiness (?? ??) — $190 per block (10 packs x 20’s)
Manchester Sapphire Blue – Dubai Version — $220 per carton
Manchester Special Edition Flow Red (Dubai Version) — $250 per block
Manchester Blue Crush (Dubai Version) — $250 per block
Dunhill Blue (UK Version) — $220 per block
Dunhill Red (UK Version) — $190 per carton
Benson & Hedges Gold — $160 per carton
Zhongnanhai brand — $180 per carton
The seller emphasizes “competitive prices” (Cheap Tobacco Australia) and the availability of well-known names such as Marlboro, Manchester, Bossku, and Double Happiness.
Delivery and Payment Methods
The seller claims to offer quick, dependable, and private shipping across Australia (Fast Tobacco Delivery Australia). They claim to accept various payment options including bank transfer, USDT, PayPal, Wise, and more. Customer communication is conducted via WhatsApp, email, and other messaging apps — a common practice in the shadow economy for online tobacco sales.
A Strange Contrast
Curiously enough, the same website that sells cigarettes (while officially noting that it is illegal to sell tobacco products to minors) also shows a “STOP SMOKING” banner with an image of lungs crossed by a cigarette.
In a part named “STOP TOBACCO”, the text says:
“Giving up smoking is hard, but every effort counts. Within minutes, your body begins to heal — and as time goes by, your health and vitality return. Let’s start today!”
This anti-smoking advice appears right next to a list of items for sale selling cartons for $160–$250 and a call to action: “Buy Cigarettes Online in Australia at the Best Price.” Such hypocrisy is typical of illegal or semi-legal cigarette sellers that pretend to care about public health while continuing to sell addictive products.
Potential Legal Problems
The text fails to mention whether the seller has a proper local permit for tobacco. Australia is recognised for some of the most severe cigarette regulations globally, including standardised packaging rules and extremely high excise taxes. The promise of low-cost smokes — especially “Dubai Edition” or “UK Version” — often suggests products that have evaded taxes, been brought in illegally, or are fake.
Final Thoughts
The online shop described above is a classic case of a shadow online tobacco business. It exploits smokers’ wish for cheaper prices in the midst of Australia’s high legal tobacco taxes, while hiding behind superficial “Stop Smoking” slogans and promises of good service. Those thinking of purchasing should remember that buying unlicensed tobacco carries not only the chance of legal trouble but also a total absence of any assurance regarding product safety and authenticity.

The Contradiction of an Australian Cigarette Website: Health Advice vs. Sales
There is an online platform offering Australians the opportunity to purchase cigarettes and tobacco with delivery to their door. The website, which goes by Australia Tobacconist Hub, shows a clear inconsistency: aggressive marketing of cheap cigarettes alongside formal warnings about the health risks of tobacco use.
Product Range
The platform’s primary focus is people who smoke seeking lower prices. Among the products listed are:
Double Happiness brand — $190 per block (10 packets x 20’s)
Manchester Sapphire Blue (Dubai Edition) — $220 per block
Manchester Special Edition Flow Red (Dubai Version) — $250 per block
Manchester Blue Crush (Dubai Version) — $250 per carton
Dunhill Blue – UK Edition — $220 per block
Dunhill Red – UK Edition — $190 per block
Benson & Hedges Gold — $160 per carton
Zhongnanhai brand — $180 per block
The seller stresses “low costs” (Cheap Tobacco Australia) and the availability of popular brands such as Marlboro, Manchester, Bossku, Double Happiness, and others.
Delivery and Payment Methods
The seller claims to offer quick, dependable, and private shipping across Australia (Fast Tobacco Delivery Australia). They say they process various payment options including bank transfer, USDT, PayPal, Wise, and more. Customer interaction is conducted via WhatsApp and email — a standard method in the unlicensed sector for online tobacco sales.
The Contradiction in Messaging
Interestingly, the identical platform that promotes tobacco sales (while officially noting that selling to persons under 18 is illegal) also displays a “STOP SMOKING” banner with an drawing of a cigarette passing through human lungs.
In a part named “STOP TOBACCO”, the text says:
“Quitting isn’t easy, but every effort counts. Within minutes, your body starts recovering — and over time, your health and energy come back. Begin your journey now!”
This public health message sits directly alongside a list of items for sale selling cartons for $160–$250 and a prompt to buy: “Buy Cigarettes Online in Australia at the Best Price.” Such double messaging is characteristic of unlicensed or “grey market” tobacco shops that pretend to care about public health while continuing to sell addictive products.
Legal Risks
The text does not specify whether the seller possesses a proper local permit for tobacco. Australia is famous for some of the strictest tobacco laws in the world, including standardised packaging rules and extremely high excise taxes. The promise of low-cost smokes — especially “Dubai Edition” or “UK Version” — often points to products that have evaded taxes, been brought in illegally, or are fake.
Conclusion
The website in question is a textbook example of a dark-market cigarette seller. It exploits smokers’ wish for cheaper prices in the face of Australia’s high legal tobacco taxes, while hiding behind superficial “Stop Smoking” slogans and promises of good service. Those thinking of purchasing should keep in mind that purchasing unregulated cigarettes carries not only the chance of legal trouble but also a complete lack of quality or safety guarantees.
