Devil is not so terrible as he is painted.. :)
Lest there be any lack of clarity...

"Perpetual motion similar to that of the amplifier but without supplying energy from the outside to the amplifier.
A typical example would be a Ventouri nozzle, acoustic sound amplifiers, Coanda effect, amplifiers and the like . .
Of course, the system must be designed very carefully the picture below is just to understand how it works.
Of course it will not be motor and alternator . .”

Feliks,

unless you are joking, this kind of “perpetual motion amplifiers” exists only in your imagination.

Take the easiest case, say “an acoustic sound amplifier” (like your acoustic guitar, regularly mentioned in the previous posts) and follow the energy.

The energy, just like the mass, cannot be created, nor be can destroyed; it just passes from body to body, from atom to atom. At the end, it is an interaction between atoms and nothing more (Boltzmann).

The total energy of the sound emitted by the acoustic guitar is ALWAYS less than the mechanical energy provided to the guitar strings.
You disagree?
Can you focus on the above simple sentence and explain what makes you think that the energy of the emitted sound is more than the energy given to the guitar strings?
Have you made any experiments / measurements that prove the opposite?
Or it is just your “feeling”?

The acoustic guitar is a good start.
Then you can “evaluate” properly your rest “perpetual motion amplifiers”.

On the other hand, I still think you are joking.



By the way, at your post 1181 it is mentioned the dual module OPOC engine of EcoMotors / Bill Gates.
Imagine having in your car a two module OPOC. When the load is light, you operate only the module near the gearbox. From time to time (when the load is heavy) the second module gets into play.
Did you think what is the reliability of this arrangement?
If not, take a look at http://www.pattakon....ariableCapacity

Half rotate my engine also can operate as a Stirling engine. Thanks to the excellent properties, having a low friction semi rotary piston, Stirling engine can be even much higher efficiency than previous versions of the conventional piston rubbing against the sides of the cylinder...

He, the current version of the flathead engine

 

http://en.wikipedia....Flathead_engine

 

And here is my version, but strangely drawn ..

dolnozaworowy1.jpg

 

The wikipedia is written with the maximum degree of pairing can get a 7: 1 And this is the fundamental flaw in the solution. Therefore, this low level of compression is because the valves need to have a place in the head to be able to go in and open up. In my constructs, valves (pistons) opening up, regress to the crankcase, so the head can be completely flat, without going into the notches on the valves. With a completely flat head, the compression ratio we receive in my design, possible 27: 1 It is a circuit are adequate for spontaneous combustion - diesel engine, which takes about 18: 1 compression ratio. So you can make the First Diesel Engine in the World with flat head ....

 

 

 

Also will not need to divide the block and heads, because my valves (pistons) can be loaded also from the crankcase, rather than the traditional valves from the head, so when the engine submission is possible in this way, the division heads and engine block becomes redundant. You can perform when the engine entirely from one piece, except for very an emergency head gasket and bolt heads that secure critical

So more or less look like the block of the world's first diesel ...

Take the case of such a pulse jet ..

 

http://en.wikipedia.org/wiki/Pulsejet

 

Take the case of such a pulse jet .. Especially his version of valveless .. I wonder why the exhaust gases from the fuel burned in the engine flow only one way? After all, the developed pressure should lead to the two parties can flow .. There's no valves ... that is, the string should be right too ... But it is not .. I wonder what it says Mr. Betz ...
Ai has little curiosity. And faster engine in Air is moving in, the better the string produces the same amount of fuel burned ... So, the speed of movement of the motor in the air ... will strengthen its capacity and within .. Interesting .. it's such an additional amplifier without additional energy from the outside ... I think that here you Betz has nothing to say ..

The intake tube takes in air and mixes it with fuel to combust, and also controls the expulsion of exhaust gas, like a valve, limiting the flow but not stopping it altogether. While the fuel-air mixture burns, most of the expanding gas is forced out of the exhaust pipe of the engine. Because the intake tube(s) also expel gas during the exhaust cycle of the engine, most valveless engines have the intakes facing backwards so that the thrust created adds to the overall thrust, rather than reducing it.

 

http://en.wikipedia....alveless_design

 

Your assumption seems to be incorrect Feliks. It would appear that exhaust gases do exit the intake pipe in a valveless design.

 

And I think what gruntguru is saying is that Betz's law is not applicable to pulse jets - valved or otherwise.

Such a thing you have to use the Windmill Red Baron .. It is much more effective and efficient than a fan, which I used in my prototype .. because I used it because I wanted it to be seen from fast shakes due to the negative pressure produced .. Also each vane pump can be used, even with the water ring seal.

I notice that the difference is using pistons instead of valves. But I would like to know the benefits in terms of power, torque, durability and rpm.

How do I see the second way of producing energy from sea waves (apparently), then I think that it is exactly the same level as the "new" way of cooling the reactor. It just reminds me that the same people invent and are supporting each other, to give evidence that only nuclear energy is a clean and cheap to produce .. Because of course, both of whatever reality they have little in common..

I notice that the difference is using pistons instead of valves. But I would like to know the benefits in terms of power, torque, durability and rpm.

a brief summary of:
So yeah .. I made two prototype engines in such a system. First, this is my thesis at the Technical University. He had to show that the engine has the possibility to work at all. The assumption has done surprisingly well ..
My second prototype, with many improvements done and its description and photos are on my website. The idea was it to work in the car Fiat 126 p on car races, which were held in Poland at the time. In my assumptions had he gives an output of around 100 horsepower at 10 000 revolutions. I made a prototype with its design and start-up to a satisfactory level of about 3 years (1000 days) View as a day of work takes a good mechanic replacing a head gasket does not, for example, in the "Lotus", and you will know the approximate costs are such a prototype and its launch . ...
All these costs were, funding of my personal funds ..
But it was worth it. Flagellum yes - inventions also sometimes surprising, in a good way. Not everything new has to be wrong. IN THIS case in good page surprise was even beyond the scope of forecasts. Namely, how are the practice has shown a prototype of the engine has an output of around 250 horsepower at 10 000 revolutions .. it is dwai know half times than the expected value. with such a large difference, finding out about it was a big threat to life ... Here a little more fully described.
 
 
Due to this process, the engine is so big power from a relatively weak engine, its use in a racing car does not make sense, because the engine would have already collapsed at the start, using his full power. Also I did not want to risk because of this, the startup was repeatedly dismantled because some surprised me, not only when it comes to the same power. These repeated cutting weakened some of its elements, so they can no longer be too much to repeat ... But at the moment, have the engine in ready to work .. You can screw it to the 10 000 cycles. Unfortunately, I will not let the torque measurement, because it would crash ended his .. Just a reality this time by two and a half times, and so exceeded the limit of sustainability, the design .. 
Strange that since 2005, despite the existence of this site, no one was willing to see the prototype at work .. However, questions are asked, and sure. You maybe someone thinks that the data you publish false. . Really, please bear the costs of a visit, and so they will be much than the venue of the construction of its new prototype, and of course a few blunders that and I had .. Operation of the engine, is in every respect a surprise in the right direction .. Maybe instead of theorizing, it is worth it alone to see for yourself. 
 
If it comes to SERVICE LIFE is sure it will be a lot more stable, because most emergency items in today's engines are running timing and head gasket, In my design of these elements is not .....
 
As regards the speed that is a structure that allows no low speed, up to 30 000 revolutions of the main shaft .. crak timing   schaft spins then only 15 000 cycles, while maintaining constant high precision charge exchange as the existing structure does not guarantee,
 
The engine has a huge advantage. The most hot item in the combustion chamber heats up,  no more than 250 degrees Celsius. This is a huge advantage, because at this temperature does not occur in the most harmful NOx pollution, .. Of course, the compression ratio can also pick up a lot ..
Adding up all the advantages and possible regulatory tions, you will get about 50 % fuel efficiency, with the same parameters driving ...
Well unless you do not believe the Displacement gives more power .. :rolleyes:

"The engine has yet to operate against a load on a dyno"?

 

After it is all published, so that everybody knew what problems one can encounter. Because even I, as the inventor and constructor, profesional engineer of the engines made a mistake until two and a half times ... Therefore, each next prototype should have all these advantages into account and be designed so that its capabilities with those able to work on a dynamometer, and more, much longer than traditional motors. The parameters say that it is worth. Without build my prototype, no one would have guessed that so many advantages of this engine can produce. At the same time, the 50% does not depend on high-power engine it will continue, which can be somewhat restrict and the same 50% on gain.

 

. Only you have to take into account the power Horrendous achieved what even the constraint can be very large, the prototype should perform very solid, and it will be worked longer than traditional large engine, even at full load. . Just fitness of this engine is larger and has a more simple possibilities of meaningful regulation, allowing more savings. 

 

To check how many existing design uses a belt drive, you can do the work for the two bikes: one four-stroke and two-stroke second. Please compare the percentage must be set aside if the dampers, the stationary bike, scattering the engine with no load, say up to 4000 rpm in each of them. The difference will be huge,
Drive traditional timing gets 10% of engine power .. but the maximum power .. Using in urban driving, say, an average of 20% of the maximum power, the drive valve timing must already use that 50% of this power, because the drive belt always gets the same amount of energy, regardless of the power used ..
 
Another type of experience can be pressed in the car that you drive, at a standstill, with the engine running. Press the accelerator pedal and keep the engine speed is 4000 rpm. You'll see a large percentage is to press the gas pedal pressed This amount of gas, it's exactly what needs to a traditional four-stroke to overcome the resistance of their own

Similar to Kosciuszko Mound ... Like so Mound in Krakow fell to the Vistula and obstructed it, we would have Tsunami from the mainland ... do not need any earthquakes ... Once the sequence of events predicted arguing against nuclear power ...
Maybe it is worth to seriously take this example, because there is always such a miracle as the heavens here we will fund .. I strongly tell against such power plants. You can not, as you believe in miracles ...

I think that we have come to some stage in the publication of new technical ideas. Although I still have a little to be published, it seems to me that at the moment you need to get to the Philosophy that the publication did not go to waste. So I propose that you read how this Philosophy looks at the present day historical perspective.... :rolleyes:

I do not quite understand, from where in the Fukushima irradiated with so much water? Surely you can create a flow of water to cool the reactors and pools, which will be held between the radiated heat exchanger reactor cooling water and the tank and clean water cooler .. then irradiated water will return to the cooling of the reactor, and there will need to be storable. Only the top up, if there are any leaks in the reactors and fuel pools .. However, pure water can be cooled by large air coolers and passed through a heat exchanger ..

"As the situation at Japan's 40-year-old Fukushima Daiichi nuclear plant goes from bad to worse—four of the plant's six boiling-water reactors have been damaged by explosions or fire, and radiation has begun leaking into the atmosphere—officials there continue to pump seawater into the reactors in a desperate attempt to cool down fuel rods and avoid a complete meltdown that could release radioactive fallout across much of the country and beyond. The move by Tokyo Electric Power Co. (TEPCO), which operates Daiichi, to use seawater doped with neutron-absorbing boron in the reactors' pressure vessels all but ensures that they will never function properly again, permanently damaging one of the world's 25 largest nuclear power stations.

Such extreme measures were necessary because the normal and auxiliary cooling systems, which circulate purified water to keep the fuel rods from melting down, failed.

It is a pity that what you quote a little place two years ago ..

 

Here, what's that supposed to take place now ..

All in all, great upset about the situation at Fukushima ... and more .. Because how can you use something over which there is only a half, and pretend to wise. I really reasonable only causes a big stress and headache ...

 

The culture must also technical culture...

Well after that our mourning have something on the front ..
No. So designing a good amplifier that amplifies much is not simple and easy ..
Here, it's about the type amplifier wind instruments. On this page, the instruments are charts that say the sound intensity can vary over a range frequencies with as much as 6 dB.,. This large difference is due to raw material from which it is made ​​instrument, with the same shape.
 
 
If we want to get a change of size (volume) using a classic amplifier-loudspeaker system is to get the 6 dB of sound, we need to use as much as 4 times greater electrical power, not, for example, 50 watt, well, up to 200 watts .. Up so much growth in sound, as it turns out, it gives us the right material for the trumpet ..
 
 
 
Yes, we can easily lose with this energy gain, as we will use the wrong material ....
 
Now the one of the simplest experiments of physics ..
It is a "kitchen an experiment." We take two tablespoons can be of tea or soup. Take them by their ends and bringing together bellies ... Between tummy wpuszczmy very small stream of water. I bet that you will not be able to maintain a 2 mm gap between them ...
We can also repeat the experiment horizontally, so that the speed of the fluid force is created ..
