[quote name='Wuzak' post='5587386' date='Mar 15 2012, 08:26']Will sufficient heat be generated in the exhaust to be used ina combined cycle situation?[/quote]
Yes, combined cycle, but also the latest trends ...
February 9, 2009 Thermoelectrics - the phenomena in which a temperature difference creates an electric potential - have been known about for almost 200 years, but practical applications have not been widespread due to their low energy efficiency. That may all now be about to change as Germany…
And since it has to work at the coal face powder (same what they use today's power plants for combustion in boilers).
can seals with carbon, similar to the scrubbing of electric motors
Metallized Carbon Corporation (Metcar) has released a carbon-graphite material for piston rings that need to seal high pressure gas in applications where the compressed gases must not come in contact with oil or grease. The piston rings are used in conjunction with carbon-graphite guide rings or carrier rings, which hold the piston centered on a cylinder bore.
Star engines were characterized biggest always force density
Below picture of the star half rotate around 10 (40) with "cylinders". for the transparency of the picture one can see only 3 additional "cylinders" more than is at the animated film.
One can also see dimensions of the whole of the engine in the assumption that every cylinder has such dimensions for the picture half rotate with the set connecting rod of the Sulzer D= engine of 900 mm and stroke 2500 mm .
So 10 (40) "cylindrical" engine half rotate about the same working capacity in comparing to the Sulzer 10 engine cylindrical on the picture below .
Sulzer: 10 Cylinders 20 m long , 15 m hight , 1500 Ton weight
Half rotate star : 10(40) "Cylinders" 4,5 m diameter , 4,5 m long
about 70 ton weight.
And most importantly.. Since in the engine half rotate mass innertia are several times Sulzer smaller than in the engine, engine half rotate can work with the much greater rotation speed.
Slzer : 102 RPM 60 000 KW
Half rotate 250 RPM 150 000 KW
In same intake work volume .
And now, the efficiency of the engine, due to the friction of the walls of the cylinder to rise about 5%. That is, it is the most efficient machine for the heat, whose efficiency exceeds 50% of the.

Re: ROLLS-ROYCE CRECY
I think the era of steam comes to an end. At most in obsolete nuclear power plants will be still used.
Half supports the engine has one very big advantage. Piston not friction on the walls of the "cylinder""Only the seals frictions cylinder
Thanks to these properties, the engine may be running on ... the coal dust.
Rudolf Diesel's first engine was built just on the coal dust, but unfortunately zacierał is at work. In the case of half rotate, will not look any login problems.Simply does not have any large surface friction
Only the directory should be chosen for personal seal. Each round you can straighten lines, of course, resistant to coal dust.....

Re: ROLLS-ROYCE CRECY
My 6 cylinder boxer..
Can have two times less cubic capacity, because that is two times smaller turnover at the flywheel.

Re: ROLLS-ROYCE CRECY
And in the meantime since the formation of the ideas, changes a lot. For example, go beyond the "magic circle of the cylinder" was the hardest thing.
When I discovered it, a new type of timing, was the new 4 stroke engine:

Re: ROLLS-ROYCE CRECY
I was with my friends in the Museum of aviation again. "I'd like him to show this demo in which the effect of the vacuum State at the top of the wings, which blows the wind from the fan, the ball is sucked in by a transparent tube
provided in the middle of the wings and a peg that pops up on the wing.
Doing this experience again, so your friend can see it, I am surprised that the ball a is NOT sucked in tube!!
It is that this experience has been vandalized, and the ball is sucked on
Vandalized based on this, with a transparent tube to the bottom was several times the seeds.
But this was not the reason for the lack of vacuum in the tube.
After arrives home, thoroughly by looking at the about the well running the show.
I noticed that the tube on the film extends over the upper surface of the wings have 70 mm
The vandalizet show the tube was brought down to equality with the upper surface of the wing.
And this was the main reason for the lack of vacuum in the tube !
Simply air her upper surface of the wing, when it encounters a simple hole in the wing, just get it and seeking to keep the pipes, eliminates any vacuum in it.!!
That is, that the ball could be the suck by the vacuum arising at the top of the wings, in this case the pipe must extend over the upper surface of the wing by about 70 mm !!!
When this tube does not extend, this does not transmit its down this vacuum, even in the smallest degree.
Why is this, explain the following drawings:
Yes so we are one of the one cases where due to vandalism, we fully the specificities of of the Red Baron Windmill...
According to estimates, the surface of the wing of a 100 m square, with a wind speed of 30 km\/h can produce approximately 750 KG lift.
To get 100 KG of thrust of the propeller to the ultralight trike, the engine must have a power of about 50 KW
You can take also denied that the 100 KG over da US 50 KW electrical Dynamo.
Which had managed to seize the entire lift such 100 m ^ 2 wings which is 750 KG, a power Dynamo would be 300 KW.
The Windmill of the Red Baron 100 m x 30 m = 3000 m ^ 2 and this will give us the 9000 KW.
Now you can build 10 such wings one above with which 30000 m ^ 2 = 90 MW.
No and now depends on how many% of this theoretical power we capture this lift and exchange it into electrical current.

Re: ROLLS-ROYCE CRECY
Here are a few solutions that can some of the problems to solve..
Surely you will need to test them in practice, before se makes the right decisions as to the shape of the structure of the drive.
Perhaps such a solution with a single tube might be the most efficient, because it will most laminar flow
Or a Cutter Heron
Of course, a whole can be properly enclosed guard areodynamic...
Well, here an example, if the electric drive can also adapt to the helicopter. Turbine itself would be inside the helicopter, but it would not be permanently linked to the rotor, so that no torque moved...
It is air- gear drive
