If they move to the Thames or Potomac River this venturi nozzle:

D=1 meter, L = 5 meter V min 0,6 m/sec V max 6 m/sec , Flow 500 kg/sec .....

A little electric power can be done...

The same goes for the sea tidal and sea currents.

Animation showing how using venturi nozzle drives the gyroscope to the flight instruments. Historically, the aircraft was not an electric current...
But now, if we do the jets in the right size, we thus also powered electric generator...






Even used a double Venturi nozzle, in order to increase the vacuum to best drive "turbine"

So yes, I think it best to start with what everyone has long-standing knowledge and know how not to reinvent the wheel.
Ideally we'll see this in professional.

I think that for the first time, that's enough.

I still have some of the existing achievements Venturi Nozzle:

I think that the next step will be to manufacture large quantities of electricity from wind, by the use of Venturi nozzles

The Underground Windmill.

Underground windmills will be an really new alternative to the Atom

Helicopter rotor blades without ???

Without blades

four animation.

Perhaps,perhaps...

One of the problems with current windmills is that they must be constantly pointed to the wind, not only to optimize energy generation, but also lest they might sustain some damage.
A set of nozzles, say in a six or eight pointed star arrangement, could feed a fixed windmill, which as you suggest, could now operate in a horizontal plane and be sustained in rails or whatever.
The nozzles, being quite solid structures, can take side winds, and one would just need to open/close the appropriate valves within the nozzle star at the right time depending on the direction of the wind, much easier and faster than rotating a whole windmill with the wind. One could also combine any number of such tunnels and stack nozzles at different heights.
The wind capturing device and the energy generating device become effectively uncoupled from each other.
About something that you think?

[quote name='gruntguru' post='4982321' date='Apr 20 2011, 01:11']Total power in the wind.
Power = 0.5 x Swept Area x Air Density x Velocity[sup]3[/sup]
from http://www.reuk.co.uk/Calculation-of-Wind-Power.htm...[/quote]


In the Wikipedia is a big mistake or inaccuracy
Call it what you think.

Now why is that:

Kinetic Energy = Mass x 0.5 x Velocity2 It is certainly true.

But when it comes to the calculated mass is no longer referred to as:

Mass / sec (kg / s) = Velocity ( m / sec ) x Area ( m2 ) x Density (kg/m3 )

In my opinion, if we count the mass, we must indicate the volume of the cylinder, which is in addition to its surface and its length.

Here, due to an error or a" shortcut calculations" assume that the length of the cylinder is equal to 1.

But it is not always true mass depends also on the length of the cylinder, because they can be 50 meters.

Of course, if you will take part in the formation of energy.

Even in a new traditional windmill blade width can have two meter, and now the model is invalid.

* But because the masses are Surface x L x Density. Always.

Well, where we have L ? ?

By the way. What has to calculate the speed of her weight?

Holidays are approaching, so we do spring cleaning. For sure we will use the vacuum cleaner. We can using such a vacuum cleaner to see how the underground windmill will run . Namely, you should close the pipe vacum cleaner is best without the caps to a small fan, for example, to cool the CPU, or a computer power supply. We will have a working model of an underground windmill......

The following picture shows the sports exhaust, which are built with a relatively long individual pipes from each cylinder. Their length L is crucial for their proper operation. Mass departing exhaust with a volume of such tubes will help the new portion of air intake into the cylinder, while the common valve opening. This mass is precisely calculated for the speed at which it will perform a so-called dynamic charge of the engine



Just the energy contained in the exhaust of precision of the volume of the exhaust manifold vacuum in the cylinder does.


Happy Easter to everybody !
