My version of car wind.Solo of trumpet

Will test whether it could be faster than the wind... Boat too....

You never know what is beyond the present ...

Ice boat

But faster than the wind, it is possible ....

But perhaps the experience of the Ice Race can to help you change the aerodynamics in F1?
But in F1, there are winds above 300 km / h !
Fighter aircraft F-104 starts at a similar velocity. Right then, about 700 KG per 1 square meter load.
If using a well-sculpted are did the 700 KG used to accelerate boild F1 ......

I think that not everything has been said in the aerodynamics of F1.....

700 KG at 1 m^2 - 70 KG forward at 10 dcm^2 aditional F1 wings....

Can it save fuel by using the wings ??

It all depends on how clever way it uses the wing...

Or, the cyclist can get speed of 200 km / h?
And they like to ride in the peloton?

What on earth are you on about?

Put in Google Andrew Feliks, maby you find it

[lesweeks]

OK, done that. Still don't see how it relates to Classic Boats - i.e. what this forum is all about.

A balloon classic boat pulling you seen ? He may be at an altitude of 200 meters. There is always the wind is blowing, even as the sea is smooth as a table.
In addition, hydraulic may enlarge even more boat speed.

[lesweeks]

I think you miss the point. Classic Boats require wind at sea level to drive their sails. I'm sure you'll receive a far more appreciative response in another forum. Out.

This problem towers
can be resolved with Jazz Big Band. Just half of the turbine rotates in one direction and half in another page.

I did this study in the Venturi nozzle turbine and the calculations have a rather surprising results. Back to front.

Well, energy is the same at the entrance, like a normal windmill. Only I noticed that the amount of energy produced by the windmill, the third power (cube)depends on the speed of the wind.
Windmill depends on the diameter of the second power (sqare).
So I started with a lot of it is better to improve the efficiency of wind turbine using wind speed increases, and not via increasing the diameter of the fan.
Serves to increase the velocity venturi nozzle

V^3 , D ^2

As curiosity I enter the number of Hp has the arrangement of 15 m / sec. = 270 Hp


You probably use a turbine engine derived from a helicopter, to generate such energy

Doctor!

Can you pop in here a moment?

[quote name='gruntguru' post='4676641' date='Oct 29 2010, 09:53']Read the article. This is the absolute truth and applies to any wind turbine.

It might take a while to get your head around Betz's law, but unless you do, you are not in a position to dismiss it.

EDIT. By the way, 16 MW is the TOTAL power in a 100m diameter disc in a 15 m/s wind. Any machine extracting more than that has disproved the 1st law of thermodynamics - a perpetual motion machine.

I'm not an executioner. I help people with this type of issue for a living.[/quote]


Well, that warning was fuller, that I give you that for a Venturi entrance diameter of 100 m and wind speed 15 m / s flows as much air and treatment by 230 pieces CF6 engines of Boeing.

However, one more proof that the sails are much more efficient than the windmills.
Last Polish sailing ship "Fryderyk Copin" broke the mast in the North Sea and towed to Falmouth.
http://www.fryderykchopin.pl/?id=o-zaglowcu&sub=dane-techniczne

As you can see in the data sheet, the speed of an internal combustion engine Hp Scania 538 is 9 knots.
However, a sailing speed of 16 knots. Sails area is 1,200 square meter..

Obtaining such a ship speed of 16 knots just by driving it through the internal combustion engine would involve a minimum of about 2000 Hp.

However, the speed of the ship has been on their sails, even if it sails can not be exactly perpendicular to the direction of swimming, because it would obstruct each other with the wind.
So I have to be at a high angle to the direction of flow, which also means that only part of the force obtained from the sail, pushing the ship forward.

We can assume that the pool surface that can sail power forward. That is, 600 square meters.
This ship has the speed at 12 m / s wind.

And now Let's calculate how much, under the windmill can give us an area of 600 square meters of the wheel at a speed of 12 m / s

6 About the same perpendicular usable space as the ship sails00 m / 3,14 =191 , 191 sqrt =13,8 m , 13.8 X 2 = 27 m D widmil.

About the same perpendicular usable space as the ship sails.

Well, now we calculate how much power will give us a windmill with a diameter of 27 meters and wind speed 12 m / sec.

(12 x 12 x12 x 27 x27 / 1530) 0,4 = 326 HP

As you can see from the calculations where the power produced by the windmill is several times smaller than the engine power needed to flow the speed of 16 knots. (Teoretical 2000 Hp)
So you can tell from this example that the power produced by a windmill is 6 times smaller than the power produced by the sails.
or even this theory, the 100-meter windmill has 16 megawatts of power theory is not the absolute maximum power which disposes of the wind flowing through it.
According to this calculation gave the sails to six times more, - 30 megawatts.
Yes, I recommended that slowly read the theory about the new use of the wind ...


New widmil theory

However, the perpetual motion I would be careful. Because God every day we founded the thunderstorms. You know how much there is electricity? and does not need to use either sail or wind, in order to make electricity out of nothing.
And new dixieland:

I wish I understood more of what you are saying. If you are extracting those kind of energies, you deserve great success, and your work will be valued and respected by many poor people.

Graphically, it is very exciting and beautiful stuff, by the way.

welcome back eff, i think i`ve missed you

What on earth are you on about?

He thinks that if you put a wind stream through a venturi you can extract more energy with a turbine at the throat than you could without the venturi. This suggests that he does not have a strong grasp of fluid dynamics or indeed of basic physics. Or spelling.

I think he needs to buy less of that dodgy foreign tobacco.

There's a thousand and one of these types of things on the internet. People have created genuine engineering masterpieces in an effort to get the next breakthrough, but they don't work because they forget the fundamental rule of everything: You get nowt for nowt.

Still, I suppose that in the same way alchemy furthered science by finding out what doesn't work, these people are doing the same with physics, so... well, keep going fella. You never know, we might all be wrong in a massive way. Chances are pretty slim though.

not vice versa. normal windmill is a very primitive machine. even sail; is much more efficient
(Some 6 times). Venturi ... more. wind energy is enough in itself. see what makes big waves.

[beserksail]

Feliks, you are certainly making waves fella. Good luck.

It is proposed to be called Venturi widmill: " The Cube Turbine "

Do you know that such a large cooling towers at power plants are made of reinforced concrete walls with a thickness of 12 cm on average?

I'm very curious if that work well, though for that tip wentturi Inject and burn some fuel.
The calculations on the calculator Venturi, that, if the temperature of the air flow would be about 60 degrees Kelvin higher, the speed of the jet that increased by 50% !

If this is not too much to add, that was such a low temperature turbine engine
During low-wind, he could give a little energy.
It was like a ramjet engine
ramjet

jet helicopter


Well, such a complete install on the mountain. Would give as much energy as the whole of Poland produces.

Andrew, you divvie (not a complement) this is the Classic Boat Forum.
If you have a scheme to extract free power why not post it on the Bonkers Forum?

 

[Feliks]

case you do not know, where is the thread "need electricyty currend " ?
unless more is needed on the classic boat race?
