Yes, HYN, Andrew.

I have silently read all you ideas for some time now and have been very impressed with your creativity.
However, the more I think about it, the more I believe the time of the petrol engine is drawing to a close and the future is electric. If you could apply your impressive mind to batteries .... ?

Another way of getting electricity from hot exhaust pipes. Termionic generator, such as the electron tube. Current density obtained is about 10 watts of 1 cm square area of ​​the outlet pipe

Of course, the acquisition of the MHD generator, which has electrodes inside..

To assist the electron reactions, a high voltage can be applied, as in TIG welding machines,..

But nothing to prevent the high temperature of the inner cathode acquired using shale gas, or coal
if we pipe with a radius of 10 cm heated, it will receive its length 1cm, 600 watts, which is enough for the house to its length of 20 cm or 12 KW .... ....
Extremely small heating stove diameter 20 x 20 cm, and everything we have in the house for electricity, including heating ..
In this case, the inner tube should have fins to really depriving heat of combustion.

They're called eductors, used for industrial processes all over the world. They were also used in steam locomotives in the 19th century. Basically you use a high pressure gas source to accelerate a much larger flow rate of air, a bit.

Yes, you right . Industrial processes : http://www.croll.com/

Of course, I see that freed the next ideas of something we are very happy. Introduced only basis to be developed. Now I am going to have such a number, which encourages the implementation of this idea. Venturi nozzle is one in the figure is the front surface of 3.14 x 2.1 x 2.1 = 13, 8 cm sqare.
6 pieces battery has 6 x13, 8 = 83.0 sqare cm. that is, it is only the surface 8 x 10 cm ....
A man riding a bicycle is at least a surface of 50 x 50 cm = 2500 sqare cm. Theory can obscure the surface without loss, for which he will be hidden. So such sixpack can theoretically put 2500/83 = 30 pieces ... without magnification face of the rider. So these 180 pieces of brass drums ....

Or you could put a streamlined helmet onthe rider and gain far more.

You do realise that the energy recovered by the air motor will be at best a small fraction of the energy lost to aerodynamic drag of the venturis?

No... :rolleyes:

If on the brass cylinder with electric gyro cut the steps for air, we get a full hybrid-electric-air drive ...For sure the electric motor would be well-cooled, which contributes to the miniaturization ..

The end of such passive sports engine exhausts:

Posted Image

These old-style sausages only reach about 0.2 atmosphere vacuum. A new way of sucking exhaust ejector via a venturi is able to achieve 0.8 atmosphere vacuum. We can add it to the engine power of about 30% if the well will adjust camshaft....

As a result of additional air into the exhaust also added clarity will improve as a result of combustion gases....

The company has also achievements in the treatment of gases, both solid particles and NOx ..
For large trucks and marine engines, you can give the water cleaner exhaust. Then, no longer see the black smoke from the exhaust pipe truck. A vacuum is created and injected via a closed loop water will improve engine efficiency as a significant ..

It might - but the power required to drive the suction system would be several times any power gained. Damn that "perpetual motion" rule.

No. If a traditional single exhaust with long pipes, that's to do it just to increase the engine power ... Here, instead of a long tube relatively very short venturi nozzle and the air can be let in only when you need full power jet. Certainly the driven venturi vacuum in the air is much large than the normal long pipe .. :rolleyes:

It is just as if it was "Turbo" on the exhaust side... :D

This is a bit off the subject but in Oz in the 1950's there was a gadget that it seemed every second car on the road had. It was called the "Kleinig Extractor" and it was a venturi type of arrangement that was attached to the very endof the exhaust pipe. The idea being that the wind from the car's speed went into the venturi and sucked on the exhaust pipe end. It was claimed by the makers to give an increase in fuel economy - but I think it was generally accepted that it had no measurable effect.

Which reminds me - the TV has ads on again for the "Hiclone" (I think it's called) - I doubt that it does anything either.

I think the most important thing is for you to learn to distinguish between "witches" of scientists ... But it takes many years of reliable acquisition of knowledge, at least at the level of a scientist ... Then you can prophesy and appropriate examples to quote...

Living in Krakow, We had to learn to verify the information from the newspaper "Pravda" in Moscow.
"Pravda" in translation is True....
Unfortunately, many people with so-called "scientists" cocking his nose, he went to school for two years longer than others .. I think they can start the reaction, which does not know how to stop the problem and leave others to thousands of years ... Here is an example of how "Scientists" invented a new method of cooling the reactor ..

Here is a "right" to verify..

I think that was told to us that found a new way to dispose of nuclear waste, after which longer even leak out, then they will not be anyone to harm the health claim ... If so, I think that now they should accept nuclear waste from all over the world and take care of after them .. Because unless the Columbia River has some mysterious properties of neutralizing radioactive leaks ....

Once again, I will return to produce electricity for the help of the MHD generator. Everything is locally renowned roughly on the subject presented here.
http://www.britannic...power-generator

From other sources I found out that the biggest difficulty was to obtain high stability of our power. But today, thanks to patent my friend, who at the end of the 60 lived in Krakow and was in the same club as me HAM. Station club had prefix SP9KHR and I ran as the transmitter of surplus U.S. - BC-610. My good friend, Tadeusz Bator, efficiently assisted me in this work and launched a SSB transmitter power of 1 kW at the club. A colleague at the beginning of the 70 he emigrated to Sweden. There, in 1982 received a U.S. patent on the device that we now effectively helps in achieving sustainable energy sources .. This is the patent as the inventor:
https://docs.google....s/US4371917.pdf

Now this version of the microprocessor is very popular, and we can easily obtain current, high stability of the MHD generator. It's an old idea with a new face ..

To be economically competitive, a coal-fired power station would have to combine an MHD generator with a Termionic generator in what is termed a binary cycle. The hot gas is first passed through the MHD generator (a process known as topping) and then on to the termionic of agenerating plant (the bottoming phase).
The third system is a framework for jet engine jet gases coming from the double thermal cycle. All three components are mounted, as in the classic treadmill, and drive generators disposed on the rotation axis, or to the external parts of the treadmill....
An MHD power plant employing such an arrangement is will known as an" open-three cycle".

Poor Chesy ... but it shows its superiority to the limited "scientists" ... and this is the third time ... supposedly to three times a charm .. Thanks to this picture, which shows the ineffective actions planned by the "scientists" in order to provide current, also see "professional" electricians employed in the nuclear power plant ... Namely, you can see at a glance that the cable mesh used here are not quite matching the power supply wire (as you can see, 50 mm2) currently used for this section are structured differently (with a thick tube symmetrical to the cable mesh). These were in the last century used by Tesla .. Clearly, the narrowest cross-section of wire mesh at its base there is a section of 50 mm2 ..... It is not surprising that Chase wanted to warm up ... Also, a method for isolating the tight mesh wire with electrical tape like electrical work in villages Congo ... a little more, having reserved electricians are now using special thick-walled heat-shrinkable tubing, in addition to the printed kind of phase / zero to Chase know where, do not warm up. ..

whether it's an intake or exhaust, a venturi or extractor can only produce a max pressure differential equal to the ambient pressure. There can also be greater pressures created by inertia effects of the fluid mass flow. Ultimately, it boils down to how much energy is transmitted to the gas flows.

Yes, indeed, you have provided true depending on ..
But he and others're trying to improve the efficiency of its windmill, however, take advantage of them .. I think that the way indicated by me are true and fair things develop ...The maximum value of the vacuum, indeed can not be greater than one atmosphere, but be aware that he can make a tornado, or hurricane, where the pressure difference is only a few dozen hectoPascal .... Because it is important that quantity possible we can in a relatively easy way to get ..

And keep in mind that the turbine engine with a power of 100 KW flows only 1 KG per second ( 1 m^3), and it produces such great power, with its relatively small size

One part of the reply to "when", is for example the case of such a drag, "windmill". Under normal conditions, standing statically on the ground windmill his case at all practically drag, we do not care, because we have any number of fan blowing on the wind. And now the resistance front, as will be larger, only the rigidity of its mounting must also be greater. Practically the value of the resistance front, even if it is larger, a large amount of available free of wind, makes no need to worry, we have the resistance front .... But from the moment when the "wind", we begin to produce, for example, an electric motor car, it is known that the resistance front "fans" will have a major impact on the amount of electricity needed to maintain a speed of "wind" (car). . Know that the windmill of "hole in the middle" will have less resistance. and even the shape of the hole to be similar to the airfoil wing, his leading the resistance may be at the level of resistance of this air wing and have even just 10% of the resistance of a flat plate, with the same profile section ... If it is only 10% of the and the amount of energy required to achieve this speed "wind" (car) will also be at the level of 10% of the energy needed to overcome the resistance of a planar face. So that is one of the first steps to reduce our price lunch, is the study of our "fan" in the wind tunnel in terms of the reduction of the resistance front, just what it is in their cars and their coefficient Cx

You can see that at higher speeds, the propeller can be very small ..

As you can see the propeller drive in serious applications
So may be small and of recognition, a lot of power to control such a large fighter, because at higher speeds the propeller is more efficient. Its efficiency according to the speed increases up to the third power in the dependency ..

right on the apron in front of the hangar, and yet it was the Museum of Aviation, I played my models on a Wire ... I made ​​a nice deck Tarpan plane ... Sorry did not start, bi was too small only 2.5 cc engine and was required 5 cc .. but this did not have .. I could only dream of ..

Feliks - With regard to your idea earlier about applying venturi suction to a turbine - maybe you should try applying the venturi vacuum to a 1950's car windscreen vacuum motor. I have no idea how well it would work (or if it would work at all) - but I can see that a venturi-and-motor (whether turbine or positive displacement") could possibly have some advantages over a wind turbine.

Five to go.

Oh, yes, of course :wave:
On another forum

If you had even a basic understanding of engineering, you wouldn't feel that way.

Feliks has the sort of naive ideas that "environmentalists" have when they make sweeping generalizations about how doing X will save the world.

These designs are hair brained and outlandish, at best, with very little utility in the real world.

That small prop on the airplane is a small generator that powers the hydraulic and navigation software. Yes, when you are flying 500mph, you can generate 10hp by coasting. You WILL NOT power an entire city with the same principle and a 1' dia prop unless you are traveling at the speed of light.

I would LOVE to see some actual calculations. Math is math. Anyone with math skills should be able to read and interpret his calcs. Post those and I'll give him some credit. Until then, this guy is yelling the bible aloud from the street corner.




All right, we'll use the math ...
At the beginning of your data correct some of the aircraft speed. If it is to be an emergency control of the airplane, that's for sure, it must be to enable the load, ie the propeller must give sufficient power, as you have specified about 10 HP power control ... It's just that the aircraft lands at a speed of 220 km / h, and it must work perfectly yet. Propeller has a diameter of about 30 cm.

Well now using venturi calculator, count the venturi nozzle, which is in its narrowest point is 300 mm, so that the propeller be able to run when inserted into it. As you have specified, at the speed of 220 km / h it will give the 10 Hp.
I asked to facilitate the original input parameter of the nozzle diameter to 1000 mm (1m). her throat identified on the 300 mm. There's a quiet propeller would seem to shoot ... Here are the results of this calculator venturi ... input speed is 25km / h and the speed of the throat is 284 km / h, which is significantly more than the 220 km / h landing ... So we should calmly from the propeller to obtain these 10 Hp power ....

Now you should do such an experience (or as you have enough imagination you can not do): You have to cut out some plywood, or flat plates made of plastic, and cut out the circle with a diameter of 1000 mm (1m). So cut the wheel, you have to fasten themselves to the chest or his back. It should then get on the bike, and try to accomplish this on a bicycle pedaling speed of 25 km / h. I think it lets you easily measure .. A man riding a bicycle is not achieved by 1 Hp ... but quietly get this rate, the pinned wheel with a diameter of 1 m.
This wheel has the same, or even greater air resistance as a venturi nozzle with a diameter of 1 meter original input. But this gives us the nozzle throat, as he You noted about 10 Hp, because in the throat, the air flows at a rate ~ 10 times greater than the speed of Input, or 280 km / h.,
And the propeller can give us the 10 HP. It is 10 times more than we can give strength to propel the bike with the circular wheel strapped to us. I think that in order to achieve a speed of 25 km / h, we do not need more than 300 watts .... So, if the bike mount the front section of the nozzle 1000 mm, it will get the 10 Hp in her throat on the propeller and drive the bike with the nozzle to a speed of 25 km / h, we only need 300 watts ..


I think the only thing I have left is to wait for your points ...

Here, the first aircraft with Ram air turbine. Its ME-163 Komet:

And here the story framework:

stuff here alternators produce. At the same time, such as is sufficient to drive the the bicycle. It gives as much power as the guy who races

Now matching jets such dimensions alternator, it will have the characteristics needed to drive the bike (and other vehicles as well).It will have only 600 mm outer diameter ..

If the resistance front will be much smaller than the flat full circle. In laminar flow, may have only 15% of the value of such a flat resistance, as it has air wing profile....

Feliks - just to make it clear - are you saying that a 'bike and rider can be powered by their own slipstream?

Without researching on the internet etc. - I doubt if the Me163 was the first with a ram air turbine. I think they were fairly common on 1930's biplanes.

One to go until the new minellium.

Here is a link to the Factory RAT ....

Somehow strange lately rats have an impact on the formation of electrical energy ... Fukushima say that this mortal terror, and UTC are saying that this life .. Maybe show us in which direction we should go ...
