Here the wing crank, because the wind can produce ourselves, when we want and where we want .. remember the carousel, like hair blowing in the wind, when it was going on?

Here a link for professionals, which, in one place trying to give some knowledge about my engine. Thinking in terms of only heat the internal combustion engine and associated only with the efficiency of the internal combustion engine is a serious limitation of understanding of the internal combustion engine .. As described, the efficiency of the internal combustion engine, Primarily a depends on the efficiency to overcome the forces of inertia. Generally, twice heavier engine of the same displacement, will be much less efficient, its lighter version and the consequent efficiencies, have nothing to do with the heat .. Because overcome the forces of inertia does not cause any increase or loss heat .. So thinking only categories that everything can be reduced to the category of heat is a big mistake, because overcoming inertia can not "force" reduced to the category of heat.

Well, sometimes you can use the models made by others, and do not spend money on their models. Here you can see very well that this model boats, capable of flowing even into the wind .. But demonstrator, not even suppose that, in this way, is also a way to produce wind, because the boat is sailing faster and for this reason, the wind acting on the windmill you will be getting stronger ... if you are a boat tied to a string to floating around, it will float forever ... .. unless my eyes deceive me ..:tsk .. of course my solution, instead of the classic windmill, windmill will be Red Baron version double teaspoon, which closed Roots and the propeller will power.

Well, maybe you need to start from the simple structure ... Here a tandem bike in which the other in the rear never laze will not be ....
The experience you need to slowly gather .. the Wright brothers' first flight at the time, only 278 meters flew his machine ..

Here the newest model of the wind my car .. Only cosmetic changes on the outside .. :)


But inside the revolution ..
I present two screenshots of the simulator NASA airfoil and it is clear that at different angle of attack with a symmetrical profile, receive different values ??of lift .. From negative to positive .. or 160 KG positive, or 160 kg (320 lbs) negative (downward pushing sash) when changing the angle of attack of 30 degrees .. and dimensions of the wings 2, 5 meters square at a speed of 100 km / h (60 miles)



Well, this wing of their forces can drive the crankshaft directly ..
Here, the animation .. The angle of attack of the wing can change either electrically or mechanically (cam) There is no need for this high energy ..


Well needless to say that such a system also can work at creating their own wind ... ..

I had to publish it on Santa Claus, but that the climate summit a little hurried me .. Because after what happened there in May too tired and negotiate, as you no longer need .. maybe someone out there will send a telegram?:rolleyes:

So come on ramjet engine, such as the SR 71 .. which drives the generator on a treadmill, and give you the energy ... but when we have a stream of departing gases, after the addition of neodymium magnets can be good even with these tubes directly receive electrical energy generated MHD generator .. no as shown in the figure also how we will burn pulverized coal .. no but the engine is a framework is the same as scram jet, only at lower speeds. In 2015 Tokyo was developed in the engine scram is that with the help produced on the basis of MHD power also speeds up the exhaust gases on the MHD reverse. We need to get all our MHD mounted on the framework jet engine gave only electricity .. extra for electricity from the generator to the axis of the device .. but that's not all we can with the energy produced in this way receive .. Because the device is going to rotate in a circle with a diameter of 30 m, then we can all thermal energy from the combustion of fuel to pick up, building a 35-meter housing for the device. And WHOLE heat generated can pick up with the aid of heat recovery units (coolers or tubes such as in a steam boiler) and use it, or even to produce additional power, or (i) for heating .. This time none have not wasted

Wuzak, on 12 Oct 2015 - 03:07, said:
The SR-71 had turbojets, not ramjets.

So yes, engines SR71, a combined cycle engines .. to take-off and less than one Mach a turbine engine plays an essential role, but above the speed second element of this combination, which is a ram-jet engine (the tube that flows air) begins to play a dominant role speeds above Mach 3, giving it 82% of the total during what has at its disposal the plane. that is, if we gave up at that speed at all of the turbine engine, this string would only decreased by 18%. I think that on threads loss in our application we can afford and get rid of at all of this very complicated and expensive engine components SR 71. we are left only ram-jet, and he will be with an efficiency of about 95% at the speed .This is written in the NASA study concerning the second combined cycle Ramjet engine of the rocket engine .. rocket engine ..

But for our purposes of energy production should be enough speed less than 1 mach. Well, here the helicopter, which must be produced from 100KW power to fly ..

Except that I would not advise that a helicopter to fly .. but the current can do safely :rolleyes:

So now even a version
So here the animation ramjet engines between the wings in a spoon effect, which is about 9 times increase input speed .. Pipes of course without turbines, such as SR 71, and, so to eye with 250 MW of getting So, yes, the set of a diameter of 30 meters, having the 250 MW of power, he would have 12 pieces of such pipes since SR71, visible starter pneumatic boot, and the number 2 units would give so much energy around, a small nuclear power plant Only with the size of the power plant, even coal, consumed for own use 50 MW (high pressure pumps, blowers and fans, etc.). Here only the minimum energy for the fuel supply system, expressed in kilowatts ..
And the cost of investment that air football field, probably will be significantly smaller.
It's to improve the imagination, what I'm saying.
Well, here we have any fuel - coal dust, gas, oil.

And you know what these wings including my project still can be used? not even suppose ... :rolleyes:

This is EXHAUST. .. :D

Thus, the negative pressure is created dam that will serve to suck exhaust gas from the engine .. vacuum will remain on throughout the exhaust pipe .. will suck exhaust lot better than they do, competitive exhaust pipe curled in a "sausage" ...
And by the way a negative pressure can be so great that at some considerable speed, you can turn off the ignition .. :D and cut off the supply of fuel .. :D interesting at what it will speed .. :rolleyes:

and even before up to speed, it also can underpressure to run a turbine from the exhaust and nwtedy that the system does not have to be connected ..

Well, not to mention the alternator, which also would say fueled rotary vane pump on the vacuum ...

Yes, if so, a pair of wings spoon should be at the back of the car .... :D
