Human Nature is greed oriented. Without monetary reward many bright minds will not be motivated to take up research

Many enlightened minds can rise beyond serial Human Nature, and they approach the matter differently. Of course, they also need to be rented and have to live in and out of the future, and this should be done ... this is not tantamount to greed

Well, here is the way to create a vacuum - different in my Red Baron Windmill ... but now the first Newcomen steam engine called atmospheric, has an inaccurate name .Because actually it is a vacuum-driven engine, which gives condensed water vapor underneath the piston. In my case, this underpressure - it receives differently, from the wings put up in the wind and brought on to entrust the earth through a pipe with a large cross-section. And on the surface of the earth such a motor with pistons driving generators .. It is the most effective way, because virtually thanks to good piston sealing,  vacuum  we will not lose any losses .. thanks to this the efficiency will be high and no moving element can be seen in principle, except the rotating axis of the generator ... ..
That is why it is worth knowing the history of technology, because it contributes to the creation of new inventions.
here more about this Newcomen engine. , which may be useful to my Windmill Red Baron ... and we will have an efficient motor with a piston seal class, used to produce electricity from the wind ...
Well, it is definitely not a heat engine .. so talking about temperatures is pointless.:smokin:

And finally, we have good access to this NASA CALCULATOR for flight profiles. No Java pieces are needed.
Well, you can see that there is a place on the air profile, where the speed of the air is 3 times higher than the speed of the general .. but this is only on a small part of the profile .. But there would be set turbine ..



here a link to this calculator and you can start learning aerodynamics yourself ... before the university is formed in this direction of aerodynamic energy.

Here is the thermodynamic problem .. We have in a box, in a vacuum is a set of thermal engines with generators ... Will this set be more efficient than it would be normally installed without a box?
  it's about how laws of thermodynamics work on the Equator, and how on the Pole.
Different temperatures
  on the Equator 40 degrees Celsius and at the Pole - 40 degrees Celsius also for efficiency and the layout of the engine will be important ...?

Unfortunately, the Carnot engine is only a fragment of the reality surrounding us related to heat engines .. But most try to explain it as a generally applicable law. In the meantime, for example, you can do a simple experiment at home with a "cold engine". Just pour cold water into the sink and put a screwed plastic drink bottle into it. We will see how it will change its shape due to the cooling of the air inside by cold water. Based on the change in its appearance, we see that also the engine would be possible on this principle. Everything is relative in physics .. But learning about heat omits many important physical quantities such as evaporation, freezing and most important - time. And theoreticians come to the conclusion that entropy is steadily increasing, but what about the scientific approach cannot be reconciled too much, because what will happen if this entropy is ever going to run out ?   
I present here, probably the largest heat engine that a man can build (It is suitable for the Guinness book of records  ) And theoretically, the pressure does not play any role in it, because the balloon from below is open .. the air heats up and the balloon can rise even at 5000 meters (record is 20,000 m), then the first balloon empties from warm air and fills the second, which thanks to the scrolling line to their tether will do electricity in the generator. Then the cycle repeats, from what we release at the top warm air and the bottom one, we fill it ... The old good principle and pressure does not play any role .. It's just a curiosity that not everything with heat is a Carnot engine ..
By the way, a hot air balloon is the longest-lasting machine in the air so far - the record is over 10 days ...
This shows because maybe there are other heat engines with higher efficiency than currently known .. Anyway. there is already a contribution to new thinking ...

I guess that there is nothing infinite, as some want to convince us that it is, however ... This is certainly all the "Big Bang" that took place in their heads ... Lofd Kelvin said that a machine heavier than air can not fly. ... And all you had to do was look at the bird and put on weight him ... But he probably thought it was a divine matter, but it flies ...

Andrew

So here in slow motion you can see how the valve works in a four-stroke internal combustion engine .. You can see perfectly the "precision" of this mechanism .. It is best to watch it on the maximum screen .. You can see how the valve is when not pressed (and then there is a stroke of work with high pressure ) we are simply shaken by the effect of spring vibrations bouncing off the valve face and inertia .. At the bottom of this valve there is a "mushroom" which closes the way to the cylinder .. But since the valve stem dances so, the mushroom also makes such movements .. A since it performs these movements, even when it is "theoretically" closed, it really does not close the cylinder tightly, despite the fact that it is subject to a stroke pressure of up to 100 atmospheres. And we can imagine how much of this pressure escapes from the cylinder, on the effect of these "supposed" small, but very spoiling cylinder tightness, the movements of this mushroom .. Because at a pressure of 100 atmospheres, we can imagine that even a small gap, however, can even drop to 30 atmospheres make .. this mechanism is economical, and produced in virtually all internal combustion engines .. And complacency that the valve will be tight, because it presses it to the seat, high pressure in the cylinder is only the "wishful thinking" of the designers of such a system. because you can see that this is not true, because the valve sways and bounces off the socket, just when it should be closed ... This film helped me understand why my engine without these valves has such high efficiency and power, because how it receives in the cylinder, these 100 atmospheres, I will never lose my tightness all the time, closing the "valve", maybe like 2 atmospheres .. Well, but the amount of energy to use will be 3 times greater than in a traditional engine ... because 98 atmospheres .. And so on every cylinder .. adding to this even 40% more displacement, and twice as high achievable maximum revolutions, it also receives incredible power ten times greater than the original factory engine ... the load. Well, to find out about all this, I had to do [for 3 years of hard work a prototype of this engine, and say that it is so, although at first it did not seem to me at all, that so much is possible .. But it is thanks theoretically, to drive a Toddler (Fiat 126), with the same power as the original, you need a motor that will be smaller these ... 10 times .. But all this can not be determined by just watching the animations of my engine and criticizing me .. You need to spend your private million dollars to find out that this is the case ... And this film also shows that it is possible with all the imperfections of the current valve system ...
Even an indicator pressure test on an oscilloscope shows us that the pressure drops, but does not show us WHERE it escapes ...  :lol:




Andrew

In this film, you can imagine that on the other side of the valves there is the same disc as at the top and of course the wedges when it is to be closed, does the same at the bottom as this disc at the top of the springs









Andrew   

Well, here in the film you can see that the valves are almost not open at higher revolutions .. The same is seen this opening, the air that is to enter the cylinder ..

And the sound that this mechanism produces is huge .. You can take my word for it that the whole sound (95%) of the four-stroke engine comes from the timing mechanism ...
My engine has only 5% of this mechanical sound,

But on the exhale ... world record ...evil

Did you like my balloons? It is a buoyancy engine .. There are already such, but operate under water .. are exceptionally fuel efficient vehicles, which you once, then 3 seconds using energy and emerges again up .. Of course the circulation of Carnot have nothing to do, although in the level covers considerable distances but the faithful his followers will try to convince us that they have ... But they do not have an orthodoxy should not be ... despite teach this way at universities ...
First about the underwater glider, of course in English .. https://en.wikipedia.org/wiki/Underwater_glider

We develop thinking further, not burdened by this Carnot ..

Do you know how much engine power goes to overcome losses in the timing mechanism? When designing, it is assumed that it is 10% of the maximum power of this engine .... But, after all, it is very rare to use the full maximum power .. to maintain speed in the city - 50 miles, usually not more than 20% of this is used maximum power .. .. But then the same amount of power goes to the camshaft ... as if we used the maximum power ... So, in fact, in driving in the city the timing drive goes up to 50% of the power used then ... we still have to overcome as much resistance as braking with a 4-stroke engine. I learned about it when I was driving a car with a two-stroke engine, which practically did not have engine braking ... So in summary - the timing drive and pressing the valve springs - I think, on average, there is 50% of the currently used power, which we need to overcome, thanks to our fuel. .. believe me.

Here, such false graphs are:

https://x-engineer.org/automotive-engineering/internal-combustion-engines/performance/mechanical-efficiency-friction-mean-effective-pressure-fmep/?fbclid=IwAR0sKmfNIWHFh66SQ3SYYGhinqNQm5mt0steiBDLUFLVH4V4_Mba2uTqzBg

There was once a discussion on this subject .. I used to think so until 1980 ... But later I looked at it differently and I know, as a result of years of reflection and experience, that all this is sucked from the finger, these heat and mechanical losses, unfortunately .. Here is an evident example showing that the resistance to movement of the crankshaft and the camshaft is several times larger, so these charts are a complete fairy tale ..
And that's why they are not building new efficient engines ... previous engineers. and until they revise their views, they will not build a better engine .. Here you stubbornly do not see that my engine with the same capacity, the main piston sucks 3 TIMES more air into the cylinder, and you try to compare it to a traditional engine that sucks 3 times less ,, And you say that the losses on my pistons according to these graphs are much larger .. Yes, maybe (but I'm not sure) but they suck these 3 times more charge into the cylinder and This is an undeniable physical basis, but my engine must be more efficient , no matter whether you acknowledge or not...

https://www.youtube.com/watch?v=oP1n0N_cU0U&feature=youtu.be

You can see that the shaft itself is very light, you can turn the hand, it is very difficult to mount the camshafts, even using a long arm wrench .. I think that even 5 times more force is needed for this .. I used to rotate several engines that I modernized and I repaired and I know that this is a big difference in this strength .. And this will also be confirmed by every efficient engine mechanic...
And that's why modern engineers, unfortunately, put them down and are unable to make a working engine from 23 HP to 250 HP ... and until they start to find out, however, it is, they will not do it ... And I do a lot so that they deign find out ... until health allows.



These and this graph shows that the valve train movement resistance, despite increasing the turnover by 6 times, does not consume more energy .. It's some wonders, because they also have their inertia, and bearing resistance also increases, similarly to the resistance in shaft bearings crankshaft ... and as a result of increasing turnover from 1000 to 6000, this green space should be much wider ... .. and this indicates a very unreliable development of this chart. Because the valves also have their inertia, which increases with the square of revolutions, and thus the friction in the drive system of these valves also ...

Well, here such a movie, if it could work such a balloon power plant ..  
Well, for example on a ship, if the exhaust gases from the engine were used, half in the fields with air, so that they were not too hot, then such a balloon with a capacity of 500 KG could be filled in 1 minute, if the ship's engine operated at full power. At one turn gives 20 m ^ 3 a salon with a high temperature .. multiply it by 100 revolutions per minute gives 2000 m ^ 3 .. Probably a few balloons would be needed .. But also such a diesel power plant on the mainland can be improved a little in this way .. to no heat was wasted ...

https://www.new4stroke.com/balons.mp4



of course with any other heat source of 80 degrees Celsius it is also possible ..



Andrew 

That's right, but you can always buy a German product at home, which is the 3rd type of energy on Earth .. And the one who set the law is Lord Kelwin, who thought that birds fly because it is a divine matter ... But that's nobody this sharp view of reality bothers and many repeat it ...
But here is this German idea ...

This German idea works or doesn't work, but certainly when applied to my balloons it shows the way to go .. My balloons are not perpetuam motion, just a giant heat engine for low temperature, which has already been proven to work because the balloon is rising due to this relatively low temperature inside.
And this German way how to properly enlarge it, it will work, enabling the previously wasted energy released into the air to use, and it can be energy released into the air from a coal-fired power plant, gas-fired power plant, or four-stroke energy engine (atomic power plants also), which only have no more than 50% efficiency, and the rest they release into the atmosphere And now maybe even with 40% of this energy can be used for electricity production, which can even give 90% of the total efficiency to give us such a new power plant ... 

Well, such "balloons" would have to have dimensions of 10 x 20 x 10 meters, and they could be built like scenes at outdoor concerts .. but the skin weight would be balanced, as well as thermal illumination in the form of foam polystyrene lining could be done .. No only the height of the tower is a problem .. Al I think that the height of 200 meters is quite real, that is, say, these 6 pieces of such "balloons" on this tower could work on one side, which would give a pull of up to 3000 KG ..

Well, for example, exhaust fumes from a diesel power plant could be introduced there, and with cooling hot water too .. So theoretically 50% of this heat energy lost in such a power plant could be forced to work ...



Even water vapor could also be used to fill a "balloon" .. its weight is only about 0.5 KG at a temperature of 80 degrees Celsius ..
hot air pump, e.g. power plant chimney ...
and works 24 hours a day regardless of the weather ..


Andrew

Interesting properties of such an engine .. At a tower height three times greater, we will also receive 3 times more torque on the power output shaft, while we provide the same amount of heat per second....




What if the 10 ray tower was ...? it will also be 10 times more energy ...
The only limitations are the realities of technical possibilities ..
But theoretically, the energy received can go to ... infinity ...

Interesting..

Are you assuming that the hot air is still the same temperature at the top, when the bucket turns over to let the exhaust air escape?



Which would mean that you are creating power without extracting any heat energy.



Yes,  thanks for the right thinking on the project ... Alone in the beginning, I described these balloons as the largest heat engine ... ..
But you can not say that it is a heat engine, because it just does not lose heat, and gives energy ..
This escaping heat can be reused by building a roof at the top that will collect it and bring it back to the bottom of the device for refilling.
By creating good thermal insulation, the heat lost will be minimal, and only theoretically we will have to supplement the heat lost as a result of putting it into the atmosphere, and not as a result of its loss for the work.
So it's not a classic heat engine, despite the fact that it uses heat ..




Andrew

Well, I see that I need to do the mathematical calculations step by step ...
so we have a 14m x 20m x 10m = 2800m ^ 3 bucklet ... he gives STRING at these 80 degrees Celsius those 500 KG of strength ... in a line, ALL bucklets give a total thrust of 12 x 500 KG = 6000 KG .
Now the pulling wheels have a diameter of 20 meters, i.e. a radius of 10 meters .. So we get a torque of 6000 x 10 m = 60,000 Kgm.
The circulation time of 1 bouquet is 100 seconds on this road 500 meters. or 500 meters divided by the circumference of the wheel, i.e. PI x D,    3, 14 x 20 m = 62 m, i.e. 500m / 62m = 8 turns, to overcome this path ... So one turn, that is 100 seconds / 8 = 12, 4 seconds lasts, i.e. 60 / 12.4 = 4.83 RPM  per minute, on the wheel shaft,
The power we get with such parameters is 4, 63 rev / min x 60,000 kgm = 335 HP.

But now we can build it in a shaft dug in the ground, every 1000 meters deep, which is not a problem, and still part above the ground ..
And of course further permutations ..

Another third film, which will show that with COLD we can receive electric current with low efficiency .. I can determine it by the speed of the received current after cooling one side of the peltier module plate .. We get the current very quickly, despite the fact that heat is not a very fast transmitter yours.
This time we take a cold spray with the medical ICEMIX peltier available in every pharmacy.
