[quote name='Kelpiecross' post='6317600' date='Jun 18 2013, 03:26']I think there may be a way of getting around Betz' Law - as least to some extent. I should point out that what I am suggesting is not a plan to build a practical wind turbine - just a theoretical idea for capturing a greater percentage of the energy of a fixed cross-sectional area of wind than that allowed by Betz.
The idea simply is that (as I interpret the Law) Betz' Law applies only to a single stage turbine. If a series of turbines were placed in a duct similar to that shown in the first drawing of the Wiki article on Betz' Law - the duct expanding in area after each turbine to allow for the reduced velocity of the wind. The 40% of energy that gets past the first turbine has 60% captured, the 24% that gets past the second turbine has 60% captured by the third turbine and so on. Each turbine obeys Betz but overall the energy gathered is greater than that allowed by Betz and his bloody Law.
There often seems to be a way to get around the various basic laws of the universe (at least to some extent) without actually contradicting the laws. The point I am trying to make that it is not always a totally hopeless case to attempt something like Feliks is trying to do (but his idea won't work).
Did somebody else on this forum suggest this basic idea - or did I hallucinate it?[/quote]
I think that you gave a very good another example, the Betz "law "should be related but very skeptical. And it's a practice that we may work better for our imagination ... I can not but agree with the fact that my idea does not work. The images shown by me wings with a small fan, is the prototype shown in the "straight" Venturi nozzle. I assure you that with the right wind speed is very small fan rotates very quickly. Had he been exposed to the same wind without the help of the "straight" venturi nozzle, would not even be able to slowly rotate, because the relatively low wind, so little fan is not able to produce enough energy to overcome their resistance to motion. I have given, on which the profile is built, this "venturi nozzle straightened" so anyone can repeat the experience and see for yourself if it works. I was convinced and that is why I shared this information. Windmill used in the prototype rotor has a diameter of just 35 mm, the hub of which is as much as 19 mm in diameter. Even though it is "crippled" by a shoulder, shook actually fast. And he was inside the car, where the wind was not blowing at all ... Blowing in the wind wings creates a high vacuum. precisely because of this vacuum planes are flying, though is heavier than air a I are exactly the same negative pressure arising wing uses negative pressure not to fly, but to produce energy. And everyone knows that the negative pressure is created on the wing as it blows in the wind, so that so far only been used for flying plane, and will now also for the production of energy from wind. And there is no argument that it is "not working" because everyone can see that the plane is flying and a windmill, affixing to it as a vacuum cleaner, also rotates .. So a combination of both of these facts is possible, and certainly works. And there are no hallucinations. A "right" Betz who wants to talk about energy bypassing the mass, one has to such a process of its formation nohow ...
I greet those who are not afraid to have an open mind.
