"The gain in kinetic energy resulting from the increased linear velocity in the throat is offset (i.e., balanced) by the decrease of pressure in the throat. The reduction in pressure which occurs when the fluid flows through the throat is called the Venturi effect and is named after the Italian physicist Giovanni Battista Venturi (1746 - 1822) who first observed the effect."

Lesson Two: in terms of fundamental historical
Venturitubes 1937.pdf On the pictures below you can see how small the venturi nozzle is to drive the gyroscopes in the strands. My finger and applied on the next hand, illustrate the size of the venturi tube. It is almost equal to the diameter of my finger. Now, please imagine how much energy to give the fan with the same diameter of my finger... Since the narrowest point of the venturi tube, we can easily get up to 10 times higher air velocity, we can mount the engine behind the jet frame, which at high speeds the inlet has a good performance. For example, you can mount an engine on an Tourist Plane, which reaches 200 km / h at the entrance to the RAM JET would be about 2000 km / h.... This will generate additional good sequence, using a very simple engine ( or two ) Regards Andrew |

Since the gyroscope can be power, relatively high compared to the diameter of the venturi tubes (1 ") and he has the 2 ", then maybe you can do in F1 KERS Venturi "? The air sucked into the engine can be sucked through a venturi tube so, resulting in a negative pressure to drive the gyroscope, which will keep energy....:tsk That would be something like a turbine gives energy, but the intake pipe. Turbo Regards Andrew |

The Red Baron Windmill:
Due to the vacuum created by the wing, over which the wind flows, wind turbines in the channels of collective spin vacuum and provide energy.... Here you can see demonstrations of the film that created a vacuum at the top of the wing when the wind blows on him. The resulting vacuum can suck the ball into the pipe passing through the wing. http://www.youtube.com/watch?v=Fb8IFfnbjY8 By placing many of the holes on the top of the wing, use the vacuum on the entire surface of the wing. The Assembly shall meet in two sustaining supports and drives the suction fans to them with normal air pressure. This will of course be used to produce energy, and its amount will depend on the size of the system... Regards Andrew |

Well, some developing:
Of course, you must use the entire art of loving wing aerodynamics. And How companies grow one way: speed amplifier in the form of air intake venturi nozzle. Well, and a new kind of wings... Venturi nozzle flat... After all the two wings made contrary to each other.. Regards Andrew |

[quote name='gruntguru' date='Jul 6 2011, 08:37' post='5147823'] Those wings need endplates. Seriously - using the flow in a secondary device means that a lot of the wind power is wasted, because the mass flow through the turbines is much less than the wind mass flow captured by the machine. I have seen some interesting and original ideas in this thread, but you are wasting YOUR energy trying to improve on the efficiency of a modern wind turbine. [/quote] All of this, I waste my energy ,you able to understand that there are other, much more efficient ways of using wind energy. I know your great love for modern wind turbine, but you must remember that any excessive love sent your eyes, and impossible for an objective view of reality. Besides, is not just about the same efficiency, but also for it to be able to build a very simple structure that even the next 4,000 years will exist. I makes sense to build on the sea, because they almost always wind blows from one direction - from the sea. And so it will probably still over the next 4000 years... * In such a structure may be, for example, 100 such horizontal " flat venturi " and long for 300 meters. Constructed channels will lead to negative pressure turbines which generate much electricity. And the only element consuming to be turbine generators. The rest should survive 4000 years without repairs... So with these issues will be decisive, not only we can improve the efficiency of Venturi amplifier. Well unless the people have lost the ability to build such structures ... And here in a better resolution though you wanted to see more details: http://upload.wikimedia.org/wikipedi...h_Pyramids.jpg But who will be Pharaoh?? Regards Andrew |

And here's the picture of Homer family watching the Red Baron Windmill prototype with flat Venturi nozzles.
If you meet all expectations, this is a prototype of Homer performs with Stone, as Pharaoh himself had wished. And it will be a very durable building, well, for example, compared to the ridiculously short life of nuclear reactors... Best Regards Andrew |

Oh yes, a little bit of you have, then a little knowledge and work reliably over the idea and new invention ready..... Here you can see perfectly that we can get plenty of potential energy generated by the aerodynamics, without any propellers.... It allows a range of up to 3000 km by glider... http://en.wikipedia.org/wiki/Gliding Andrew |

You know perfectly well, with new ideas about the rank of the fundamental, very difficult to penetrate to the use of mass... But thanks to people like you, we can slowly try to.. Another, although not looking as Hekules, we have on video.. http://www.youtube.com/watch?v=Fb8IFfnbjY8 Instead, we can build an automatic flow of balls so that they can be sucked into the pipe. A falling ball (or WATER) with wings, they can hit their way back after a shoulder wheel, similar to a water wheel, giving him his potential energy .. Well, the automatic circuit, will cause the "Hercules" he can rest. This is just an example of how we can use another way of generating energy this way. Regards Andrew |

http://www.youtube.com/watch?v=NNbNN...eature=related http://www.youtube.com/watch?v=GPOql...eature=related http://en.wikipedia.org/wiki/Sailing..._than_the_wind Aerodynamic coefficient Cx is very small. It is certainly much smaller than in the traditional ship... This is not a traditional sail 2D, but the full 3D structure. Energy is processed and used to drive water propeller. Why can swim backwards and forwards. Like a film with 2D fan. So many of Snoopy Ship has a much higher efficiency due to 3D Andrew |

Old ideas in new study:
This gear drive in a helicopter that is bothering me. Another way to get rid of her. By the way, turned out that the rear propeller and also you can get rid of , because the helicopter does not have the torque of the main propeller. The helicopter had already been built. But it had drawbacks: no, for example, could not take full advantage of autorotation, because the propeller with a hole through the center did not have good aerodynamic properties.... http://en.wikipedia.org/wiki/Sud-Ouest_Djinnn http://en.wikipedia.org/wiki/File:He..._and_blade.jpg I missed this problem and the propeller is as it is most optimal. Also today after assuming control of the helicopter adjustable nozzle (vectoring nozzle) on the outlet gases from the turbine driven, will be very precise. http://en.wikipedia.org/wiki/Turbomeca_Palouste http://upload.wikimedia.org/wikipedi...ne_of_F-35.jpg In summary the lack of a gear transmission and rear propeller helicopter will certainly reduce weight.
